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 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.

Diesel fuel, on the other hand, has a higher energy density, and in combination with higher combustion pressures can deliver very strong torque and high thermodynamic efficiency for more ' normal ' road vehicles.

A Diesel engine can reach as high as 70 % ( Diesel's lab engine tested at 75. 6 % efficiency, VW TDI is at 46 %).

Because Diesel fuels are of low volatility, they can be very hard to start when cold.

* and vegetable oils ( which can be used only in internal combustion ( Diesel ) engines.

Other institutions, namely the " Königliche Industie Schule " ( Royal Industrial School ), the Augsburg Rudolf Diesel School of Building and Engineering ( Academy for Applied Technology ) and the Augsburg School of Art and Design can be mentioned as roots of the university.

Diesel engines can be operated on dual fuel mode using producer gas.

Diesel substitution of over 80 % at high loads and 70-80 % under normal load variations can easily be achieved.

With the addition of a supercharger or turbocharger, opposed-piston designs can make efficient two-stroke cycle Diesel engines.

Diesel and electric locomotives can work with a much lower factor of adhesion than a reciprocating steam locomotive because their power is applied smoothly, unlike the latter's pulsed power delivery.

Diesel Car magazine said of the BX " We can think of no other car currently on sale in the UK that comes anywhere near approaching the BX Turbo's combination of performance, accommodation and economy ".

Just south of the station is Metro-North's Southeast Diesel Maintenance Facility, and trains either beginning or ending their routes here can be seen snaking to and from it before or afterwards.

The Detroit Diesel Series 50 can be fueled by diesel fuel or compressed natural gas ( CNG ).

Diesel engines can produce black soot ( or more specifically diesel particulate matter ) from their exhaust.

The Coyote is powered by a Detroit Diesel 6V53T engine developing, and can reach speeds of 120 kilometres per hour.

The units are owned by Diesel Unit Preservation Associates Ltd. DUPA own other railcars which can be found in use at various preserved railways in the UK.

Diesel engines can produce strong torque at relatively low rotational speeds, which is generally desirable when driving an alternator, but diesel fuel in long-term storage can be subject to problems resulting from water accumulation and chemical decomposition.

Desperate to set things right in the last minute, Thomas decides to gather his courage to ask Diesel 10 to clear the wreckage so that George the steamroller can be retrieved to repair the runway.

Diesel 10 eventually agrees, and when the steam and diesel engines see him working alongside Thomas, they all decide that they can work together quickly to repair the damage.

Dieseling ( in the sense of engine run-on, and disregarding combustible gaseous mixtures via the air intake ) can also occur in Diesel engines, when the piston or seals fail due to overheating, admitting engine oil into the cylinder.

A later development of this engine, known as the Diesel engine can burn heavy fuels and oils.

The second theatre is powered by an independent 75 KVA Diesel Generating set and this can be detached to form a stand-alone operation theatre, and is to be used in disaster management.
