diesel engine:

· Strengthen the design to ensure the reliability: the body, crankshaft, connecting rod and other important parts of the three-dimensional finite element analysis, the temperature distribution is more reasonable, high strength, high rigidity

· Supercharger with vent valve structure: automatically adjust the intake air and intake pressure, to maintain a stable intake air charge coefficient, to maintain a good combustion, an increase of diesel engine speed range, improve low-speed and high-speed performance and emissions

· Oil pump front: to ensure oil pressure, lubrication more excellent, more reliable operation Piston forced cooling: to improve the piston heat load, reduce the deformation, cooling system is more perfect, more reliable operation.

· Fuel pump forced lubrication: full lubrication, improve lubrication, reduce the fuel pump wear, extend life, work more stable and reliable.

· Steering pump gear drive: stable operation, high transmission efficiency, better safety, higher reliability

· Air pump gear drive: stable operation, high transmission efficiency, better security, higher reliability

· Vibration optimization design: the belt with a shock absorber structure, vibration, low noise
