Automation of the cooling system for an internal combustion engine by programming a controller and using a thermal state control system

The issues of cooling control automation for an internal combustion engine (ICE) of cars and trucks are considered. An algorithm for controlling the number of revolutions of the electric motors for the liquid pump and the radiator fan, depending on the temperature of the internal combustion engine coolant is proposed. This algorithm is stir up by the Arduino MEGA 2500 microcontroller in conjunction with the motor driver. The automatic control system for the thermal state of the internal combustion engine will reduce fuel consumption, wear of the cylinderpiston group, as well as the emission of harmful substances into the atmosphere.
