Features & Benefits

● Well perform in 20000 hours reliability test and the most demanding requirements on temperature compact and metal fatigue.
● Our world-class foundry and machining factory guarantee the excellent quality and reliability of our major components.
● Alloy cast iron engine block, forged steel crankshaft and high-strength alloy connecting rod increase strength and rigidity.
● The improvement of piston cooling system reduces the piston temperature and oil consumption
● High efficient 4-valve, P fuel pump & P injector, postposition gear chamber and point-line gear-meshing patent technology improve combustion, noise level, vibration and fuel consumption
● Water cooling exhaust pipe reduces engine room temperature
● Provide dual starting methods (electric and pneumatic)
