Yuchal YC4D80-T20 Diesel engine

The diesel engine has the highest thermalefficiency (engine efficiency) of any practicalinternal or external combustion engine due toits very high expansion ratio and inherent leanburn which enables heat dissipation by theexcess air. A small efficiency loss is alsoavoided compared to two-stroke non-direct-injection gasoline engines since unburned fuelis not present at valve overlap and therefore nofuel goes directly from the intake/injection tothe exhaust. Low-speed diesel engines (asused in ships and other applications whereoverall engine weight is relatively unimportant)can have a thermal efficiency that exceeds50%. One-piece cylinder head and wet sleeve linersdesign-Ensure a longer performance life.Turbocharging system-Enhance response andperformance life, providing prompt boostacross the operating range. Fast start at low speed and excellentgradeability- Ensure vehicle deliver unmatchedperformance.Point-line meshing gear drive- Give you the best CO
