Diesel engines rely on adiabatic heating during their compression stroke to elevate the temperature sufficiently to ignite the fuel.

Diesel engines are run with an excess of oxygen to combust small particles that tend to form with only a stoichiometric amount of oxygen, necessarily producing nitrogen oxide emissions.

Diesel engines on the other hand operate on the principle of compression ignition, so that a fuel which resists autoignition will cause late ignition which will also lead to engine knock.

Recent examples of this trend include the conversion of all public transport in the city of Delhi from Diesel engines to CNG engines on the basis of the orders of the Delhi High Court ; the monitoring of forest use by the High Courts and the Supreme Court to ensure that there is no unjustified loss of forest cover ; and the directions mandating the disclosure of assets of electoral candidates for the Houses of Parliament and State Assembly.

And the ideal Otto cycle formula stated above does not include throttling losses, which do not apply to Diesel engines.

Diesel engines ( heat engines using the Diesel cycle ) are used in automobiles, power generation, Diesel-electric locomotives, and submarines.

The Diesel engine has the lowest specific fuel consumption of any large internal combustion engine employing a single cycle, 0. 26 lb / hp. h ( 0. 16 kg / kWh ) for very large marine engines ( combined cycle power plants are more efficient, but employ two engines rather than one ).

Two-stroke Diesels with high pressure forced induction, particularly turbocharging, make up a large percentage of the very largest Diesel engines.

In North America, Diesel engines are primarily used in large trucks, where the low-stress, high-efficiency cycle leads to much longer engine life and lower operational costs.

Many model airplanes use very simple " glow " and " Diesel " engines.

" Diesel " model airplane engines have variable compression ratios.

Diesel engines in a museum

Diesel engines are manufactured in two-stroke and four-stroke versions.

Diesel designed many heat engines, including a solar-powered air engine.

Companies such as MAN B & W Diesel, ( formerly Burmeister & Wain ) and Wärtsilä ( which acquired Sulzer Diesel ) design such large low-speed engines.

Diesel engines are often used for back up generation, usually at low voltages.

Diesel engines and HCCI ( Homogeneous charge compression ignition ) engines, rely solely on heat and pressure created by the engine in its compression process for ignition.

Diesel engines take in air only, and shortly before peak compression, spray a small quantity of diesel fuel into the cylinder via a fuel injector that allows the fuel to instantly ignite.

However, a Diesel engine will be more efficient overall since it will have the ability to operate at higher compression ratios.

If a petrol engine were to have the same compression ratio, then knocking ( self-ignition ) would occur and this would severely reduce the efficiency, whereas in a Diesel engine, the self ignition is the desired behavior.

) A historical implication of this is that the Diesel engine would eventually have been invented without the aid of electricity.

; Poor fuel economy: Even compared to other heavy passenger vehicles, Hummers without the Diesel engine options have very poor fuel economy.

Diesel submarines have barometers installed on them to monitor vacuum being pulled in the event that the snorkel closes while the diesels are running and, as a consequence, sucking the air out of the boat.

OPET is the first firm ever to have brought 98 octane unleaded fuel to Turkey and introduced Ultra Euro Diesel fuel to the Turkish consumers before it was launched in the European market.

Some webcomics, such as Helen, Sweetheart of the Internet, Macanudo, Van Von Hunter and Diesel Sweeties have been syndicated and published on daily newspapers ' comics pages.

Here she details how corporations such as Nike, Pepsi or Diesel have approached Culture Jammers and Adbusters and offered them lucrative contracts in return for partaking in ' ironic ' promotional campaigns.

Segar's newspaper strips also featured a number of her relatives named after other oils, including her brother, Castor Oyl, their mother, Nana Oyl ( after " banana oil ," a mild slang phrase of the time used in the same way as horsefeathers, i. e. " nonsense "), their father, Cole Oyl, and Castor's estranged wife, Cylinda Oyl ; more recently, Olive's nieces Diesel Oyl & Violet Oyl have appeared in the cartoons.

Diesel engines by their nature do not have concerns with pre-ignition.

VW was rumoured to have worked on a Diesel version of the aircooled boxer but abandoned this engine due to noise and heat issues.

1300, 1600 and 2000 engines all have a 4-speed manual gearbox ; a 5-speed manual gearbox was optional with 1600 and 2000 engines, and standard with the 1600 Economy engine, the 2300 and 2300 Diesel.

Diesel engines with traditional mechanical injector systems have an integral governor which prevents over-speeding the engine, so the tachometers in vehicles and machinery fitted with such engines sometimes lack a redline.

One night, on a local street racing gathering, he enters his modified 1995 Mitsubishi Eclipse 2G RS 420A into an illegal race with Dominic Toretto ( Vin Diesel ), Edwin ( Ja Rule ) and Ryo ( RyoTheRapper ) bartering the pink slips, due that he doesn't have enough money to bet in the race, asking for cash and respect if he wins the race.

Diesel switchers tend to have a high cab and often lower and / or narrower hoods ( bonnets ) containing the diesel engines, for all round visibility.

Diesel engines rely on fuel compression for ignition, but usually also have glowplugs that preheat the combustion chamber to allow starting of the engine in cold weather.

They have similar properties to Diesel # 2 which is used as road Diesel around the world.

( It has been argued that engines of this type might have become known as " Akroyds ", had Diesel not been a rather paranoid person not prone to giving other inventors credit.

The five-cylinder kerosene one, with which he claims to have flown over Long Island Sound on 17 January 1902 was, I believe, the first aviation Diesel.

He was admitted to the Institute nearly a year ago, yet Nurse Diesel and Dr. Montague have been keeping him there because of how much money Victoria is paying them.

The Fiat Croma was the first passenger car in the world to have a direct injection Diesel ( Turbo D i. d.

Ferrymead Railway and Diesel Traction Group locomotives and carriages have participated in each of these steam-based festivals, held on the Weka Pass Railway, except for the 2003 event.

They analyzed nine applications, mostly compilers, written in six different languages: CLOS, Dylan, Cecil, MultiJava, Diesel, and Nice.

It was mostly made of remaining players and staff of the defunct Yanmar Club, the former B-team of Yanmar Diesel F. C., later to be known as Cerezo Osaka.

* About 21 North British diesel shunters are preserved, mostly by public museums or by preservation societies on heritage railways in the UK, e. g. the Scottish Railway Preservation Society ( SRPS ) Diesel Group owns D2767 and returned this to working order on 25 June 2008.

Air whistles were used on some Diesel and electric locomotives, but these mostly employ air horns.
