Brand new Yuchai YC6J210-33 210hp diesel engine for marine
The diesel engine has the highest thermal efficiency
(engine efficiency) of any practical internal or external combustionengine due to its very high expansion ratio and inherent lean
burn which enables heat dissipation by the excess air. A smallefficiency loss is also avoided compared to two-stroke
non-direct-injection gasoline engines since unburned fuel is notpresent at valve overlap and therefore no fuel goes directly from
the intake/injection to the exhaust. Low-speed diesel engines (as used in ships and other applications where overall engine weight
is relatively unimportant) can have a thermal efficiency that exceeds 50%.
