1）The technology of electronic unit pump is interchangeable with fuel pump with electronic speed governor, which optimizes fuel system, satisfies larger power and guarantees lower               emission. The oil pump is added with a check valve to prevent secondary injection so as to achieve better combustion effect. 

2） Intake and exhaust pipes are redesigned to meet better performance requirements. 

3） Supercharger with high pressure ratio and large flow is used to increase airflow pressure, boost intake volume and effectively reduce exhaust gas emission. 

4）Cracking connecting rod and connecting rod bearing bush undergone spraying process reinforce operational and reliability and render easier maintenance.

5） Piston diameter is increased, shape of piston combustion room is improved, and vibration oil chamber structure and diamond coating piston ring are applied to increase                                 combustion efficiency and improve operating economy and reliability of engine.

6） Mass flow hand pump and filter component are added and oil-water separator is attached to ensure stable operation of fuel system.
