Abstract

The invention relates to the technical field of vehicles, in particular to an engine cooling system control method and device and an engine cooling system. The engine cooling system control method comprises the steps that the rotation speed value of an engine is obtained; when the rotation speed value of the engine is larger than or equal to the first preset rotation speed value, a control systemof a reversing fan is triggered to be started; the water temperature value of the engine and the air inlet temperature value of the engine are obtained; and when the water temperature value of the engine reaches the first preset water temperature value or the air inlet temperature value of the engine reaches the first preset air inlet temperature value, the control system of the reversing fan controls the fan to rotate reversely, and reverse blowing is conducted. In the scheme, through setting of the reasonable air inlet temperature and the optimal water temperature range, automatic control over forward rotation and reverse rotation of the reversing fan is achieved, it is ensured that weeds and scraps attached to the surface of a radiator are removed in time, and faults caused by the highengine running water temperature, the high air inlet temperature and the like are avoided.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a control method, a control device and an engine cooling system of an engine cooling system. Background technique [0002] At present, the cooling system of an automobile engine generally uses a fan to dissipate heat. The engine's operating water temperature and intake air temperature have a certain impact on the engine's emissions. After a value, manually control the reversing fan control handle to change the direction of the reversing fan. Use manual artificial control, which can only be controlled by referring to the water temperature of the engine, and the user may ignore the use of the reversing fan during normal driving. When the weeds are broken Chips block the surface of the heat exchanger, high engine water temperature alarms, high engine intake temperature leads to limited engine torque, the vehicle cannot work normally and efficiently, and at the same time, weed debri...
