Title Diesel engine
Description
(from Freebase)
A diesel engine (also known as a compression ignition engine and sometimes capitalized as Diesel engine) is an internal combustion engine that uses the heat of compression to initiate ignition to burn the fuel, which is injected into the combustion chamber during the final stage of compression. This is in contrast to spark ignition engines such as a petrol engine (known as a gasoline engine in North America) or gas engine (using a gaseous fuel, not gasoline), which uses a spark plug to ignite an air-fuel mixture. Both diesel engines and spark ignition engines are modelled by the Otto cycle. The diesel cycle (a thermodynamic model slightly different from the Otto cycle) is not to be confused with the diesel engine, both of which were developed by Rudolf Diesel and named after him. The diesel engine has the highest thermal efficiency of any regular internal or external combustion engine due to its very high compression ratio. Low-speed diesel engines (as used in ships and other...
