DK28 diesel engine parts talk about the common differences between marine diesel engines and vehicle diesel engines


The spraying method is different.


Marine diesel engines (except direct injection engines) are diesel and fuel mixed into the cylinder. The output torque of marine diesel engines will be greater than that of vehicle diesel engines. High torque will not affect the vehicle speed, but will affect the car's instantaneous acceleration and load capacity.


The vehicle diesel engine directly injects diesel into the cylinder that is already filled with compressed air.


The ignition method is different.


Marine diesel engines are ignited by compression spontaneous combustion. The fuel is ignited by the heat generated by the air compression in the cylinder. That is, air compression will increase the temperature. When the temperature of the compressed air is higher than the ignition point of the diesel, the diesel will burn. The vehicle diesel engine requires a spark plug to ignite the mixed gas.


The compression ratio is different.


The compression of marine diesel engines is greater than that of vehicle diesel engines, so its expansion ratio and thermal efficiency are relatively high, and the fuel consumption is lower than that of vehicle diesel engines.
