Yuchai Yuchai YC2115 diesel motor for crawler drill

The diesel engine has the highest thermal efficiency (engine efficiency) of any practical internal or external combustion engine due to its very high expansion ratio and inherent lean burn which enables heat dissipation by the excess air. A small efficiency loss is also avoided compared to two-stroke non-direct-injection gasoline engines since unburned fuel is not present 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%. One-piece cylinder head and wet sleeve liners design- Ensure a longer performance life. Turbocharging system- Enhance response and performance life, providing prompt boost across the operating range. Fast start at low speed and excellent gradeability- Ensure vehicle deliver unmatched performance. Point-line meshing gear drive- Give you the best co
