Engine cooling system and engine cooling control method

Abstract

The invention provides an engine cooling system and a control method thereof. The system comprises an engine, a control module, an electronic water pump, an electronic thermostat, a temperature sensorand a heat dissipation device; the temperature sensor is arranged on the engine and electrically connected with the control module; the temperature sensor is used for measuring the current temperature of the engine and transmitting the current temperature to the control module; the control module is electrically connected with the electronic water pump and the electronic thermostat and used for controlling starting and stopping of the electronic water pump and the opening degree of the electronic thermostat according to the current temperature and first target preset temperature stored in thecontrol module to enable the current temperature to reach the first target preset temperature; and the electronic thermostat is used for controlling the flow of heat dissipation fluid in a first water way. According to the engine cooling system, control over the cooling system can be accurately achieved through few electronic components, and the engine always works at the proper temperature.

Description

technical field [0001] The invention relates to the technical field of engine cooling, in particular to an engine cooling system and an engine cooling control method. Background technique [0002] As the core component of the vehicle, the engine keeps the engine working at a suitable temperature, which can reduce the fuel consumption and emissions of the vehicle. When the engine is working, it will generate a lot of heat, which will increase its temperature, so its cooling is very important. . [0003] The current cooling system has multiple electronic control components, whose functions are superimposed, resulting in control logic conflicts; the engine cooling system cannot operate according to the set temperature, and the improvement of fuel consumption is poor; there are also unreasonable control strategies, unbalanced coolant temperature, and low coolant temperature Or high, so that there is a quality risk in the engine. Contents of the invention [0004] In view of ...
