The design of engine balance shaft, vibration, stable rotating speed, the vibration is

significantly less than the same engine.

Roller rocker arm, reduces the friction between the cam and the rocker arm, reduce  engine friction loss.

The use of lightweight and small piston, reduce the inertial mass of round trip time,  greatly reducing the power loss.

The design of nozzle injection piston, effective control of piston temperature, maintaining  engine performance stable, improve the service life of the engine.

Rear suspension with existing CG models, the vehicle has good applicability.
