Abstract

The invention provides a split type cooling system and method for an engine. The system comprises a cylinder body water jacket, a cylinder cover lower water jacket and a cylinder cover upper water jacket which are arranged around an engine cylinder body. The cylinder cover lower water jacket of the engine is connected with the cylinder cover upper water jacket in series. The cylinder body water jacket is connected with the cylinder cover lower water jacket and the cylinder cover upper water jacket in parallel after the cylinder cover lower water jacket and the cylinder cover upper water jacketare connected in series. Cooling liquid passes through a water pump, then flows into the cylinder cover upper water jacket through the cylinder cover lower water jacket and is mixed with cooling liquid of the cylinder body water jacket and cooling liquid of an engine oil cooler in an electronic thermostat installation cavity, and then the mixture is redistributed. A first temperature sensor is arranged on an electronic thermostat. A radiator is connected with the water pump. A second temperature sensor is arranged at a radiator cooling liquid outlet. According to the split type cooling systemand method for the engine, the consumed power of an electronic fan is effectively reduced, so that power consumption of the engine is reduced, and the fuel economy is improved.

Description

technical field [0001] The invention relates to a cooling system, in particular to an engine split type cooling system, and to the cooling method, which belongs to the field of engines. Background technique [0002] The role of the engine cooling system is to ensure that the engine maintains the optimum temperature under all operating conditions. It is necessary to prevent the engine from overheating in summer and prevent the engine from being too cold in winter. During cold start, it is also necessary to ensure that the engine can heat up quickly and reach the normal engine operating temperature as soon as possible to meet the heating needs of the whole vehicle. [0003] By installing an electronic thermostat and adjusting the cylinder valve, the flow distribution is carried out according to the coolant demand of each cooling component, and the coolant flow adjustment of the engine size cycle is realized. When the thermostat is closed and open, according to the difference...
