Product Details

Characteristics

 

1)High-pressure oil pump is directly connected, and steel coupling and drive bearing seat of fuel pump are canceled, which reduces installation process and further enhances drive reliability.      
2)TIntegrated oil cooling and oil filtration assemblies are applied. Product appearance is optimized. Cooling and filtration efficiency is improved.      
3)Supercharger with large flow and high pressure ratio is used to improve charging efficiency and enhance combustion efficiency.      
4)Large-flow diesel filter is used to improve filtration efficiency.
