Abstract

The invention discloses an engine cooling system. The engine cooling system comprises a water pump, a thermostat, a cylinder body, a cylinder cover, an engine oil cooler, a complete vehicle radiator,a warm air heating core body, a first valve body, a second valve body and a third valve body. The water pump, the cylinder body, the cylinder cover and the thermostat sequentially communicate to forma small circulating branch. The water pump, the cylinder body, the engine oil cooler, the first valve body and the complete vehicle radiator sequentially communicate to form a large circulating pipeline. A pipeline between the first valve body and the complete vehicle radiator communicates with a cooling liquid outlet of the cylinder cover. A cooling liquid inlet of the warm air heating core bodycommunicates with a cooling liquid outlet of the first valve body. A cooling liquid outlet of the warm air heating core body communicates with the second valve body. A cooling liquid outlet of the second valve body communicates with the thermostat. The cylinder body and the engine oil cooler communicate with a cooling liquid inlet of the third valve body. A cooling liquid outlet of the third valvebody communicates with the thermostat. By means of the engine cooling system, the engine warming speed of an engine can be increased.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine cooling system. Background technique [0002] Traditional engine cooling systems are passive, simple in structure or low in cost. The design standard of the cooling system is to solve the heat dissipation problem at full load, so the excessive heat dissipation capacity at partial load will cause waste of engine power and prolong the engine warm-up time. We hope that the cold start time of the engine is as short as possible, because the engine emits more pollutants and consumes more fuel when idling. The structure and principle of the cooling system have a great influence on the cold start time of the engine. [0003] In prior art, please refer to figure 1 , figure 1 It is a structural schematic diagram of an engine cooling system in the prior art; it includes a cylinder block 01, a cylinder head 02, a water pump 03, a thermostat 04, an oil cooler 05, EGR06, a vehicl...
