Diesel

Diesel or Diesel fuel is a specific fractional distillate of fuel oil (mostly petroleum) that is used as fuel in a diesel engine invented by German engineer Rudolf Diesel. The term typically refers to fuel that has been processed from petroleum, but increasingly, alternatives such as biodiesel or biomass to liquid (BTL) or gas to liquid (GTL) diesel that are not derived from petroleum are being developed.

Diesel is produced from petroleum, and is sometimes called petrodiesel (or, less seriously, dinodiesel) when there is a need to distinguish it from diesel obtained from other sources. As a hydrocarbon mixture, it is obtained in the fractional distillation of crude oil between 250 °C and 350 °C at atmospheric pressure. Petro Diesel is considered to be a fuel oil and is about 18% denser than gasoline.

Diesel typically weighs about 7.1 pounds (lb) per US gallon (gal) (850 grams per liter (g/l)), whereas gasoline weighs about 6.0 lb per US gal (720 g/l), or about 15% less. When burnt diesel typically releases about 147,000 British thermal units (BTU) per US gal (40.9 megajoules (MJ) per liter), whereas gasoline releases 125,000 BTUs per US gal (34.8 MJ/l), also about 15% less. Diesel is generally simpler to refine than gasoline and often costs less (although price fluctuations often mean that the inverse is true; for example, the cost of diesel traditionally rises during colder months as demand for heating oil, which is refined much the same way, rises).

Diesel fuel, however, often contains higher quantities of sulfur. In Europe, emission standards and preferential taxation have both forced oil refineries to dramatically reduce the level of sulfur in diesel fuels. In contrast, the United States has long had "dirtier" diesel, although more stringent emission standards have been adopted with the transition to ultra-low sulfur diesel (ULSD) occurring in 2006 (see also diesel exhaust). U.S. diesel fuel typically also has a lower cetane number (a measure of ignition quality) than European diesel, resulting in worse cold weather performance and some increase in emissions.

High levels of sulfur in diesel are harmful for the environment. It prevents the use of catalytic diesel particulate filters to control diesel particulate emissions, as well as more advanced technologies, such as nitrogen oxide (NOx) adsorbers (still under development), to reduce emissions. However, lowering sulfur also reduces the lubricity of the fuel, meaning that additives must be put into the fuel to help lubricate engines. Biodiesel is an effective lubricity additive.

Diesel contains approximately 18% more energy per unit of volume than gasoline, which, along with the greater efficiency of diesel engines, contributes to fuel economy (distance traveled per volume of fuel consumed).

In the maritime field various grades of diesel fuel are used.

Chemical composition

Petroleum derived diesel is composed of about 75% saturated hydrocarbons (primarily paraffins including n, iso, and cycloparaffins), and 25% aromatic hydrocarbons (including naphthalenes and alkylbenzenes).[1] The average chemical formula for common diesel fuel is C12H26, ranging from approx. C10H22 to C15H32.

Synthetic diesel

Wood, straw, corn, garbage, and sewage-sludge may be dried and gasified. After purification the so called Fischer Tropsch process is used to produce synthetic diesel. [2] Other attempts use enzymatic processes and are also economic in case of high oil prices. Synthetic diesel may also be produced out of natural gas in the GTL process. Such synthetic diesel has 30% less particulate emissions than conventional diesel (US- California) [3].

Biodiesel

Biodiesel can be obtained from vegetable oil and animal fats (bio-lipids, using transesterification). Biodiesel is a non-fossil fuel alternative to petrodiesel. It can also be mixed with petrodiesel in any amount in modern engines, though when first using it , the solvent properties of the fuel tend to clear out all the garbage that has built up from the petrodiesel and can clog fuel filters. Biodiesel has a lower gel point than regular diesel, but is comparable to diesel #2. This can be overcome by using a biodiesel/petrodiesel blend, or by installing a small heater in your fuel system, but this is only nessecary during the colder months. There have been reports that a diesel-biodiesel mix results in lower emissions than either can achieve alone. A small percentage of biodiesel can be used as an additive in low-sulfur formulations of diesel to increase the lubricating ability that is lost when the sulfur is removed.

Chemically, most biodiesel consists of alkyl (usually methyl) esters instead of the alkanes and aromatic hydrocarbons of petroleum derived diesel. However, biodiesel has combustion properties very similar to regular diesel, including combustion energy and cetane ratings. Paraffin biodiesel also exists. Due to the purity of the source, it has a higher quality than petrodiesel.

Uses

Diesel fuel is very similar to heating oil which is used in central heating. In Europe, the United States and Canada, taxes on diesel fuel are higher than on heating oil due to the fuel tax, and in those areas, heating oil is marked with fuel dyes and trace chemicals to prevent and detect tax fraud. Similarly, "untaxed" diesel is available in the United States, which is available for use primarily in agricultural applications such as for tractor fuel. This untaxed diesel is also dyed red for identification purposes, and should a person be found to be using this untaxed diesel fuel for a typically taxed purpose (such as "over-the-road", or driving use), the user can be fined $10,000 USD on the spot. Also, in the United Kingdom and Northern Ireland it is known as red diesel, and is also used by agricultural vehicles. Diesel fuel, or Marked Gas Oil is dyed green in the Republic of Ireland. The term DERV (short for "diesel engined road vehicle") is also used in the UK as a synonym for diesel fuel. In India, taxes on diesel fuel are lower than on gasoline as majority of the transportation, that transports grains and other essential commodities across the country, runs on diesel.

Diesel is used in diesel engines, a type of internal combustion engine. Rudolf Diesel originally designed the diesel engine to use coal dust as a fuel, but oil proved more effective. Diesel engines are used in cars, trucks, motorcycles, boats and locomotives.

Packard diesel motors were used in aircraft as early as 1927, and Charles Lindbergh flew a Stinson SM1B with a Packard Diesel in 1928. A Packard diesel motor designed by L.M. Woolson was fitted to a Stinson X7654, and in 1929 it was flown 1000 km non-stop from Detroit to Langley, Virginia (near Washington, D.C.). In 1931, Walter Lees and Fredrick Brossy set the nonstop flight record flying a Bellanca powered by a Packard Diesel for 84h 32m.

The very first diesel-engine automobile trip was completed on January 6, 1930. The trip was from Indianapolis to New York City - a distance of nearly 800 miles (1300 km). This feat helped to prove the usefulness of the internal combustion engine. The following year Dave Evans drove his Cummins Diesel Special to a nonstop finish in the Indianapolis 500, the first time a car had completed the race without a pit stop. That car and a later Cummins Diesel Special are on display at the Indianapolis Motor Speedway Hall of Fame Museum[4].

Westport claims to have invented a process called Westport-Cycle [5] with comparable efficiency using natural gas and petrodiesel.

Audi will fight for the overall win at the 24 Hours of Le Mans in 2006 with the Diesel-powered R10. This is the first time a maker has competed for the overall prize with a Diesel-fueled vehicle.

Other uses

Bad quality (high sulfur) diesel fuel has been used as a palladium extraction agent for the liquid-liquid extraction of this metal from nitric acid mixtures. This has been proposed as a means of separating the fission product palladium from PUREX raffinate which comes from used nuclear fuel. In this solvent extraction system the hydrocarbons of the diesel act as the diluent while the dialkyl sulfides act as the extractant. This extraction operates by a solvation mechanism. So far neither a pilot plant or full scale plant has been constructed to recover palladium, rhodium or ruthenium from nuclear wastes created by the use of nuclear fuel.

The ethical implications of producing, distributing, or watching fansubs is a topic of much controversy even when fansub groups do not profit from and cease distribution of their work once the series has been licensed. (Translated from Atomnaya Energiya; 76: No. Watching subtitled Japanese versions is usually seen as the intended method of watching anime by enthusiasts. al, Atomic Energy, 1994, 76(6), 442-448. Although it is a violation of copyright laws in many countries, some fans watch fansubs, recordings of anime series that have been subtitled by fans. et. DVD releases often include both the dubbed audio and the original Japanese audio with subtitles, are typically unedited, and lack commercials.

Torgov, V.G. ; Tatarchuk, V.V. ; Druzhinina, I.A. ; Korda, T.M. For the fans who may object to the editing and dubbing of anime, DVDs may be their preference. So far neither a pilot plant or full scale plant has been constructed to recover palladium, rhodium or ruthenium from nuclear wastes created by the use of nuclear fuel. The anime may also be edited to alter cultural references that may not be understood by a non-Japanese person and companies may remove what may be perceived as objectionable content. This extraction operates by a solvation mechanism. Licensed anime is modified by western distributors through dubbing into the language of the country. In this solvent extraction system the hydrocarbons of the diesel act as the diluent while the dialkyl sulfides act as the extractant. Anime is available outside of Japan in localized form, referred to as licensed anime or Dubs.

This has been proposed as a means of separating the fission product palladium from PUREX raffinate which comes from used nuclear fuel. Prequels and alternate stories are commonly adapted from the original. Bad quality (high sulfur) diesel fuel has been used as a palladium extraction agent for the liquid-liquid extraction of this metal from nitric acid mixtures. Not all successors to an anime are a sequel to the original story. This is the first time a maker has competed for the overall prize with a Diesel-fueled vehicle. Originally an OVA, it spawned three movies, three television series, and several spinoff titles and specials. Audi will fight for the overall win at the 24 Hours of Le Mans in 2006 with the Diesel-powered R10. A good example is Tenchi Muyo!.

Westport claims to have invented a process called Westport-Cycle [5] with comparable efficiency using natural gas and petrodiesel. A title that starts as a popular television series might then have a movie produced at a later date. That car and a later Cummins Diesel Special are on display at the Indianapolis Motor Speedway Hall of Fame Museum[4]. It is very common for one title to spawn several different releases. The following year Dave Evans drove his Cummins Diesel Special to a nonstop finish in the Indianapolis 500, the first time a car had completed the race without a pit stop. Most anime can be categorized as one of three types:. This feat helped to prove the usefulness of the internal combustion engine. Many non-Japanese cartoons are starting to incorporate mainstream anime shortcuts and symbols to appeal to anime's tremendously growing fanbase and cut costs.

The trip was from Indianapolis to New York City - a distance of nearly 800 miles (1300 km). This approach combined with Otsuka's "money shots" make key animators important individuals in the style and production of an anime film. The very first diesel-engine automobile trip was completed on January 6, 1930. The Hakkenden is particularly extreme, showing constantly shifting styles of animation based upon the key animator that worked on that particular episode. In 1931, Walter Lees and Fredrick Brossy set the nonstop flight record flying a Bellanca powered by a Packard Diesel for 84h 32m. The most extreme examples of this can be found in Mindgame or The Hakkenden. Woolson was fitted to a Stinson X7654, and in 1929 it was flown 1000 km non-stop from Detroit to Langley, Virginia (near Washington, D.C.). In Japan starting with the animation director Yoshinori Kanada (as a means to save time and money) each animator brings his/her own style to the work.

A Packard diesel motor designed by L.M. In most animation produced around the world animators are all forced to conform to a set style by the director or animation director. Packard diesel motors were used in aircraft as early as 1927, and Charles Lindbergh flew a Stinson SM1B with a Packard Diesel in 1928. Another unique aspect of anime not found in other commercial animation markets is the lack of a directoral system. Diesel engines are used in cars, trucks, motorcycles, boats and locomotives. In contrast, titles such as Only Yesterday, a film by Isao Takahata, take a much more realistic approach, and feature no stylistic exaggerations. Rudolf Diesel originally designed the diesel engine to use coal dust as a fuel, but oil proved more effective. Some titles make extensive use of common stylization: FLCL, for example, is known for its wild, exaggerated, stylization.

Diesel is used in diesel engines, a type of internal combustion engine. The degree of stylization varies from title to title. In India, taxes on diesel fuel are lower than on gasoline as majority of the transportation, that transports grains and other essential commodities across the country, runs on diesel. Embarrassed characters will invariably produce a massive sweat-drop, which has become something of a stereotype of anime. The term DERV (short for "diesel engined road vehicle") is also used in the UK as a synonym for diesel fuel. Male characters will develop a bloody nose around their female love interests (typically to indicate arousal) -- this is supposedly due to blood rushing to the face in an exaggerated blush. Diesel fuel, or Marked Gas Oil is dyed green in the Republic of Ireland. Angry women will sometimes summon a mallet from nowhere and strike someone with it, leading to the concept of Hammerspace.

Also, in the United Kingdom and Northern Ireland it is known as red diesel, and is also used by agricultural vehicles. Angry characters may exhibit a "vein" or "stressmark" effect, where lines representing bulging veins will appear on their forehead. This untaxed diesel is also dyed red for identification purposes, and should a person be found to be using this untaxed diesel fuel for a typically taxed purpose (such as "over-the-road", or driving use), the user can be fined $10,000 USD on the spot. Other stylistic elements are common as well; often in comedic anime, characters that are shocked or surprised will perform a "face fault", in which they display an extremely exaggerated expression. Similarly, "untaxed" diesel is available in the United States, which is available for use primarily in agricultural applications such as for tractor fuel. Another variation of this style is "chibi" or "super deformed"; which usually feature huge eyes, an enlarged head, and small body. In Europe, the United States and Canada, taxes on diesel fuel are higher than on heating oil due to the fuel tax, and in those areas, heating oil is marked with fuel dyes and trace chemicals to prevent and detect tax fraud. Indeed, through Ribbon no Kishi, Tezuka set a stylistic template that later shōjo artists tended to follow.

Diesel fuel is very similar to heating oil which is used in central heating. [1] When Tezuka began drawing Ribbon no Kishi, the first manga specifically targeted at young girls, Tezuka further exaggerated the size of the characters' eyes. Due to the purity of the source, it has a higher quality than petrodiesel. Cultural anthropologist Matt Thorn argues that Japanese animators and audiences do not perceive them as inherently more or less foreign. Paraffin biodiesel also exists. Some Western audiences have interpreted such stylized eyes as more Caucasian. However, biodiesel has combustion properties very similar to regular diesel, including combustion energy and cetane ratings. Tezuka found that large eyes allowed his characters to better express their emotions.

Chemically, most biodiesel consists of alkyl (usually methyl) esters instead of the alkanes and aromatic hydrocarbons of petroleum derived diesel. The most common is the large eyes style drawn on many anime characters, common mainly due to the influence of Osamu Tezuka, who was inspired by the exaggerated features of Western cartoon characters such as Betty Boop and Mickey Mouse and from Disney's Bambi. A small percentage of biodiesel can be used as an additive in low-sulfur formulations of diesel to increase the lubricating ability that is lost when the sulfur is removed. Some examples have become so common that they are often described as being definitive of anime in general, and have been given names of their own. There have been reports that a diesel-biodiesel mix results in lower emissions than either can achieve alone. While different titles and different artists have their own unique artistic styles, many stylistic elements have become extremely common. This can be overcome by using a biodiesel/petrodiesel blend, or by installing a small heater in your fuel system, but this is only nessecary during the colder months. Some higher-budgeted television and OVA (Original Video Animation) series also forego the shortcuts found in most other anime.

Biodiesel has a lower gel point than regular diesel, but is comparable to diesel #2. Other animators like Tatsuyuki Tanaka (in Koji Morimoto's Eternal Family in particular) use squash and stretch, an animation technique not often used by Japanese animators; Tanaka makes other shortcuts to compensate for this. It can also be mixed with petrodiesel in any amount in modern engines, though when first using it , the solvent properties of the fuel tend to clear out all the garbage that has built up from the petrodiesel and can clog fuel filters. Directors such as Hiroyuki Imaishi (Cutey Honey, Dead Leaves) simplify backgrounds so that more attention can be paid to character animation. Biodiesel is a non-fossil fuel alternative to petrodiesel. Some animators in Japan overcome production values by utilizing different techniques than the Disney or the old Tezuka/Otsuka methods of animating anime. Biodiesel can be obtained from vegetable oil and animal fats (bio-lipids, using transesterification). These movies have much higher production values, due to their anticipated success at the box office.

Such synthetic diesel has 30% less particulate emissions than conventional diesel (US- California) [3]. Exceptions to these rules are early classic films, such as those produced by Toei Animation up until the mid 1960s, and recent big budget films, such as those produced by the enormously successful Studio Ghibli. Synthetic diesel may also be produced out of natural gas in the GTL process. Animator Yasuo Otsuka was the pioneer of this technique. [2] Other attempts use enzymatic processes and are also economic in case of high oil prices. These are commonly referred to as "money shots" outside of Japan, where more effort is put into the animation of one scene to give it emphasis over the rest of the work. After purification the so called Fischer Tropsch process is used to produce synthetic diesel. There are often scenes where the frame rate of the animation far exceeds the quality of the rest of the production.

Wood, straw, corn, garbage, and sewage-sludge may be dried and gasified. (See also limited animation.). C10H22 to C15H32. The overall effect of these techniques, such as reduced frame rate, several still shots and scrolling backgrounds, has led some critics to accuse anime of choppiness or poor quality in general. Petroleum derived diesel is composed of about 75% saturated hydrocarbons (primarily paraffins including n, iso, and cycloparaffins), and 25% aromatic hydrocarbons (including naphthalenes and alkylbenzenes).[1] The average chemical formula for common diesel fuel is C12H26, ranging from approx. Anime studios have since perfected techniques to draw as little new animation as possible, using scrolling or repeating backgrounds, still shots of characters sliding across the screen, and dialogue which involves only animating mouths while the rest of the screen remains absolutely still, a technique not wholly unfamiliar to Western animation. In the maritime field various grades of diesel fuel are used. This was intended to be a temporary measure to allow him to produce one episode every week with an inexperienced animation staff.

Diesel contains approximately 18% more energy per unit of volume than gasoline, which, along with the greater efficiency of diesel engines, contributes to fuel economy (distance traveled per volume of fuel consumed). Osamu Tezuka adapted and simplified many Disney animation precepts to reduce the budget costs and number of frames in the production, though it should be noted that Disney films made in the west are not anime. Biodiesel is an effective lubricity additive. This may be due to a philosophy of applying more effort into each of a few drawings than less effort into one of many. However, lowering sulfur also reduces the lubricity of the fuel, meaning that additives must be put into the fuel to help lubricate engines. The drawing style used in anime is counter productive to the animation process, having far too many details and subsequently making it difficult to keep the number of drawings comparable to other cartoons with design ethics that stress simplicity. It prevents the use of catalytic diesel particulate filters to control diesel particulate emissions, as well as more advanced technologies, such as nitrogen oxide (NOx) adsorbers (still under development), to reduce emissions. Another type of Anime CDs release are Drama CD, featuring songs and tracks which makes use of the seiyū to tell a story, often not included in the main anime.

High levels of sulfur in diesel are harmful for the environment. Despite the word "image" in the CD's name, it only contains music and/or "voice messages" (where the seiyū talks with the audience or about herself), making the listener think that the character him/herself is singing. diesel fuel typically also has a lower cetane number (a measure of ignition quality) than European diesel, resulting in worse cold weather performance and some increase in emissions. In addition to the themes, the seiyū for a specific anime also frequently releases CD for their character, called Image Albums. U.S. Opening and ending themes, as well as insert songs, are frequently performed by popular musicians or Japanese idols, so in this way, songs become a very important component of an anime program. In contrast, the United States has long had "dirtier" diesel, although more stringent emission standards have been adopted with the transition to ultra-low sulfur diesel (ULSD) occurring in 2006 (see also diesel exhaust). ED) often make commentary about the plot or the program as a whole, and are often times used to highlight a particularly important scene.

In Europe, emission standards and preferential taxation have both forced oil refineries to dramatically reduce the level of sulfur in diesel fuels. Insert songs and ending songs (abbr. Diesel fuel, however, often contains higher quantities of sulfur. The theme song (also referred to as the Opening song or abbreviated as OP) usually matches the overall tone of the show, and serves to get the viewer excited about the upcoming program. Diesel is generally simpler to refine than gasoline and often costs less (although price fluctuations often mean that the inverse is true; for example, the cost of diesel traditionally rises during colder months as demand for heating oil, which is refined much the same way, rises). BGM is used to set the tone of a given scene, for example Neon Genesis Evangelion 's "Decisive Battle" is played when the characters are making battle preparations and it features heavy drum beats and a militaristic style which highlights the tension of the scene and hints at the action to follow. When burnt diesel typically releases about 147,000 British thermal units (BTU) per US gal (40.9 megajoules (MJ) per liter), whereas gasoline releases 125,000 BTUs per US gal (34.8 MJ/l), also about 15% less. The most frequent use of music in Anime is background music or BGM.

Diesel typically weighs about 7.1 pounds (lb) per US gallon (gal) (850 grams per liter (g/l)), whereas gasoline weighs about 6.0 lb per US gal (720 g/l), or about 15% less. Anime series with opening credits use the opening theme song as a quick introduction to the show. Petro Diesel is considered to be a fuel oil and is about 18% denser than gasoline. Skilled BGM composers are highly respected in the anime fan community. As a hydrocarbon mixture, it is obtained in the fractional distillation of crude oil between 250 °C and 350 °C at atmospheric pressure. It is for this reason that anime music is often composed and performed by 'A-list' musicians, stars, and composers. Diesel is produced from petroleum, and is sometimes called petrodiesel (or, less seriously, dinodiesel) when there is a need to distinguish it from diesel obtained from other sources. Anime soundtracks are big business in Japan, and are often times met with similar demand as chart topping pop albums.

. Much like western live-action cinema, anime uses music as an important artistic tool. The term typically refers to fuel that has been processed from petroleum, but increasingly, alternatives such as biodiesel or biomass to liquid (BTL) or gas to liquid (GTL) diesel that are not derived from petroleum are being developed. Hanaukyo Maid Team is based on the French maid fantasy.

Atlanta, GA: U.S. Anime has many genres, with as many as traditional, live action cinema. Toxicological profile for fuel oils. Anime features a wide variety of artistic styles which vary from artist to artist and is characterized by stark, colorful graphics and stylized, colorful images depicting vibrant characters in a variety of different settings and storylines, aimed at a wide range of audiences. 1995. This term is much more common in Europe since Manga Entertainment started out in the UK. ^ Agency for Toxic Substances and Disease Registry (ATSDR). An alternate explanation is that it is due to the prominence of Manga Entertainment, a distributor of anime to the US and UK markets.

Among English speakers, manga usually has the stricter meaning of "Japanese comics". In Japan, manga can refer to both animation and comics (although the use of "manga" to refer to animation is mostly restricted to non-fans). In more recent years, anime has also frequently been referred to as manga in Europe, a practice that may stem from the Japanese usage. Since anime or animeshon is used to describe all forms of animation, Japanimation is meant to distinguish Japanese work from that of the rest of the world.

The term Japanimation is much more commonly used in Japan to refer to domestic animation. In general, the term now only appears in nostalgic contexts. The term survived at least into the early 1990s but seemed to fade away shortly before the mid-1990s anime resurgence. It saw the most usage during the 1970s and 1980s, which broadly comprise the first and second waves of anime fandom.

Anime is sometimes referred to by the portmanteau Japanimation, but this term has fallen into disuse. Anime can be used as a common noun, "Do you watch anime?", as a mass noun, "How much anime have you collected" or as a suppletive adjective, "The anime Guyver is different from the movie Guyver". Hence, the pronunciations "ah NEEM" and "uh NEEM" are generally considered incorrect. As with a few other Japanese words such as Pokémon and Kobo Abé, anime is sometimes spelled as animé in English with an acute accent over the final e to cue the reader that the letter is pronounced as [e].

Some theorize the word comes from the French animé ("animated") or "les dessins animés" (animated drawings) and pronounce it as "ah nee MAY", though the Japanese themselves deny this theory, and the fact that it is written in Japanese syllables as アニメ (anime) rather than アニメイ (animei) further lowers its credibility. The English word anime is a transliteration of the abbreviated version of this Japanese term, and it is typically pronounced as /ˈænɪˌmei/, or "ANN ih may" ("AH nee may" is a less common variant). The term is a broad one, and does not specify an animation's nation of origin or style. Both the original and abbreviated forms are valid and interchangeable in Japanese, but as could be expected the abbreviated form is more commonly used.

It is a direct transliteration and reborrowed loanword of the English term "animation." The Japanese term is abbreviated as アニメ (anime, pronounced: /ɑnimɛ/ ). The Japanese term for animation is アニメーション (animēshon, pronounced: /ɑnimɛːʃɔn/), written in katakana. The 1990s and 2000s saw an increased acceptance of anime in overseas markets. In the 1980s, anime was accepted in the mainstream in Japan, and experienced a boom in production.

During the 1970s, anime developed further, separating itself from its Western roots, and developing unique genres such as mecha. The history of anime begins at the start of the 20th century, when Japanese filmmakers experimented with the animation techniques that were being explored in the West.

Anime may also be adapted into live action television programs. Anime is often influenced by Japanese comics known as manga. Anime may be broadcast on television, distributed on media, such as DVDs, or published as console and computer games. Anime is aimed at a broad range of audiences because there are a wide range of different genres that any series may be categorised under.

Storylines may feature a variety of characters and may be set in different locations and in different eras. Anime is characterized by character and background styles which may be created by hand or may be assisted by computers. Anime (アニメ) is a style of animation originating in Japan. Opening credits, closing credits, and eyecatches may sometimes be found in OVA releases, but not universally.

Popular OVA titles include FLCL, Bubblegum Crisis, and Tenchi Muyo!. Titles often have a very regular, continuous plot best enjoyed if all episodes are viewed in sequence. As a general rule OVA anime tends to be of high quality, approaching that of films. They are most commonly released directly to video.

OVAs are typically two to twenty episodes in length; one-shots are particularly short, usually less than film-length. OVA (Original Video Animation; sometimes OAV, or Original Animated Video) anime is often similar to a television miniseries. "Eyecatch" scenes are often found in TV series anime and are generally similar throughout the series. Most TV series anime episodes will have opening credits, closing credits, and often an "eyecatch", a very short scene, often humorous or silly, that is used to signal the start or end of the commercial break (as "bumpers" in the United States are used in a similar fashion).

One full season is 26 episodes, and many titles run half seasons, or 13 episodes. Most episodes are about 23 minutes in length, to fill a typical thirty-minute time slot with added commercials. Television series are generally low quality compared to OVA (Original Video Animation) and film titles, because the production budget is spread out over many episodes rather than a single film or a short series. Television series anime is syndicated and broadcast on television on a regular schedule.

There are also theatrical shorts derived from existing televisions series and billed in Japanese theaters together to form feature-length showing. These may, however, be longer than the average movie. Other types of films include compilation movies, which are television episodes edited together and presented in theaters for various reasons, and are hence a concentrated form of a television serial. Some examples of these are Winter Days, and Osamu Tezuka's Legend of the Forest.

Some anime films are only released at film or animation festivals and are shorter and sometimes lower in production values. Popular anime movies include Akira, and Spirited Away. Films, which are generally released in theaters, represent the highest budgets and generally the highest video quality. An example of this style is Gravitation.
