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 diesel 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).
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 ...
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.
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 ...
Perkins Engines Company Limited is primarily a diesel engine manufacturer for several markets including agricultural, construction, material handling, power generation, and industrial. It was established in Peterborough , England in 1932 and has been a subsidiary of Caterpillar Inc. since 1998.
Low speed diesel engines like the MAN S80ME-C7 have achieved an overall energy conversion efficiency of 54.4%, which is the highest conversion of fuel into power by any single-cycle internal or external combustion engine. [9] [10] [11] Engines in large diesel trucks, buses, and newer diesel cars can achieve peak efficiencies around 45%. [12]
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 ...
