Cooling water jacket is cast in both the cylinder head and the cylinder block of the diesel engine.After the coolant is pressurized by the water pump, it enters the cylinder water jacket through the water distribution pipe.The coolant absorbs the heat from the cylinder wall while flowing, the temperature rises, and then flows into the cylinder head water jacket, enters the radiator through the thermostat and pipe. At the same time, due to the rotation of the fan, air blows through the radiator core,so that the heat of the coolant flowing through the radiator core is continuously dissipated, and the temperature is reduced, Finally, it is pressurized by the water pump and then flows into the water jacket of the cylinder again,so that the continuous circulation will increase the speed of the diesel engine.in order to make the front and rear cylinders of a multi-cylinder diesel engine cool evenly,generally diesel engines are equipped with a water pipe or cast water distribution room in the cylinder block.with a water pipe or cast water distribution room in the cylinder block.The water pipe is a metal pipe, along the longitudinal heat outlet, the larger the pump, so that the cooling strength of each cylinder before and after is similar the whole machine cooling evenly.
