Problems solved by technology

[0004] However, when the engine temperature is low, there is no need to turn on the active grille. At this time, turning on the active grille will increase the fuel consumption of the vehicle; and when the engine temperature is too high, only the active grille can dissipate heat for the vehicle, which is not enough to meet the requirements of the vehicle. Heat dissipation requirements cannot effectively reduce the fuel consumption of the vehicle

Abstract

The invention relates to an engine cooling system and a control method thereof. An engine comprises a small circulation pipeline and a large circulation pipeline, and a heat dissipation water tank is arranged on the large circulation pipeline. The system is characterized by comprising an electromagnetic clutch water pump, an electronic thermostat, a driving grille, an electric control fan and a controller, wherein the electromagnetic clutch water pump is arranged on a converging pipeline of the small circulation pipeline and the large circulation pipeline; the electronic thermostat is arranged on the large circulation pipeline; the driving grille is arranged on one side, facing the vehicle advancing direction, of the engine; the electric control fan is arranged between the driving grille and the engine; and the controller is electrically connected with the electromagnetic clutch water pump, the electronic thermostat, the driving grille and the electric control fan. The system can respectively control the running speed of the electromagnetic clutch water pump, the working state of the electronic thermostat, the opening degree of the driving grille and the rotating speed of the electric control fan according to the current engine water temperature, the current engine rotating speed and the current engine air inlet temperature. The oil consumption of a vehicle is reduced while the water temperature of the engine and the air inlet temperature of the engine are kept in the optimal temperature interval.

Description

technical field [0001] The present application relates to the technical field of vehicle control, in particular to an engine cooling system and a control method thereof. Background technique [0002] With the development of vehicle technology, the number of vehicles is increasing, which also leads to an increase in carbon emissions. The fuel consumption of the vehicle is directly proportional to the carbon emission of the vehicle. By reducing the fuel consumption of the vehicle, the carbon emission can be effectively reduced. Therefore, how to reduce the fuel consumption of vehicles is an urgent problem to be solved at present. [0003] In the traditional technology, by controlling the opening and closing of the active grille of the vehicle, the opening of the active grille is changed according to different ambient temperatures and vehicle speeds, so as to achieve the effect of using the natural flow of air to cool the engine, thereby reducing the fuel consumption of the ve...
