1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).
However, a real 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 ...
Whereas all EMD and Detroit Diesel two-stroke engines employ forced induction, only some EMD engines employ a turbo-compressor system. Some Detroit Diesel engines employ a conventional turbocharger, in some cases with intercooling, followed by the usual Roots blower, as a turbo-compressor system would be too costly for certain very cost ...
Napier Deltic—a high-speed, lightweight diesel engine used in fast naval craft and some railway locomotives. SVO—Straight Vegetable Oil—alternative fuel for diesel engines. Wärtsilä-Sulzer RTA96-C—world's most powerful, most efficient and largest diesel engine. WVO—Waste Vegetable Oil—filtered, alternative fuel for diesel engines.

In a naturally aspirated engine, air for combustion (Diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines, namely petrol direct injection) or an air/fuel mixture (traditional Otto cycle petrol engines), is drawn into the engine's cylinders by atmospheric pressure acting against a partial vacuum that occurs as the piston travels downwards toward bottom dead centre ...
The 1.1 L (1,120 cc) U diesel engine is a 3-cylinder version of the 1.5L U series unit and is made with cast iron block and aluminum cylinder head with chain driven DOHC with 4 valves per cylinder, Delphi common rail direct injection (CRDi), variable geometry turbocharger (VGT) and intake air swirl control.
In engineering, the Miller cycle is a thermodynamic cycle used in a type of internal combustion engine. The Miller cycle was patented by Ralph Miller, an American engineer, U.S. patent 2,817,322 dated Dec 24, 1957. The engine may be two-or four-stroke and may be run on diesel fuel, gases, or dual fuel.
