Product Description

An energy-saving and eco-friendly power product with reliable structure, advanced performance and high performance/price ratio.
It uses a split type engine block whose strength and rigidity are superior to those of the gantry type and the tunnel type, able to bear higher explosion pressure. It achieves higher power and ultralow fuel consumption. Noise and vibration are smaller.
The engine block uses water-jacketed rapids belt and piston, which significantly lowers the operating temperature of the piston and the piston ring,and improves the operational reliability and service life of the diesel engine.
The stainless steel integral cylinder head gasket can bear high cylinder pressure and work reliably. The cylinder bolts do not come loose and the cylinder head gasket is not destroyed. The engine has strong cooling capacity, good lubricating capacity and a large margin, able to adapt to a high temperature of 45℃ and altitude environment.
