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%.

* Felxible –can be customerized according to customer’s request, drawing will be submitted for approval. Such as taking off radiator and replacing with the heat exchanging system, total power solution such as gear box coupling and canopy design.

*Durability- With YUCHAI engines have been engineered to meet the durability and performance needs of light truck applications.

* Long-Life Expectancy – these critical parts are manufactured by leading companies, other part comes from reliable manufacturers, these sets guarantee long functional life, outstanding performance, and high efficiency.

* Easy availability of the spare parts -- the key parts are same as parts for vehicle diesel engine,better exchange and universality and durable.

* Easy maintenance –Diesel engine not require heavy maintenance. It is very easy, safe, and simple to use. Well-planned and preventive maintenance measures are generally available for these sets which are also low in cost.
