Diesel engine

The diesel engine is also known as the compression-ignition engine, it is a internal combustion engine that uses heat compression to ignite the fuel source that is injected into the combustion chamber. Diesel engines have the highest thermal efficiency on any standard internal or a external combustion engine, because of it very high compression ratio. A low speed diesel engine is usually used in ships, where overall engine weight does not matter that much. Diesel engines are manufactured in two or four stroke.
