1）Integrated cylinder head made of high-alloy cast iron is used, and cylinder head with AVL tangential air passage is applied, which reduces swirl flow ratio, increases intake flow                      coefficient and airflow intensify, airflow pressure and power, and substantially reduces emission.

2）The design of double water pump and mass flow engine oil pump improves cooling capacity of diesel generator working with high thermal load under high power; use of external                 oil cooler enhances cooling and lubrication capacity and meets application in regions of different ambient temperature.

3）The exhaust pipe with supercharger in the middle is compact in structure.

4）The body is made of vermicular graphite cast iron and internally equipped with an auxiliary oil passage. The piston is cooled in a way of forced oil injection through special cooling                 nozzle, featuring high strength and powerful shock absorption, to reduce thermal load of the diesel generator.

5) Shape of piston combustion chamber is improved, and oscillation structure is applied to improve combustion efficiency and increase operational economy and reliability of the                     engine.
