Intelligent thermal management system for diesel

Abstract

The invention discloses an intelligent thermal management system for a diesel. The system comprises an ECU, a rotating speed sensor, a load sensor, a temperature sensor, a pressure sensor, an electronic control water pump, an electronic control thermostat and an electronic control fan, wherein the rotating speed sensor is connected with the input end of the ECU, the load sensor is connected with the input end of the ECU, the temperature sensor is connected with the input end of the ECU, the pressure sensor is connected with the input end of the ECU, the electronic control water pump is connected with the output end of the ECU so that electronic control can be achieved for the rotating speed of the electronic control water pump, the electronic control thermostat is connected with the output end of the ECU so that electronic control can be achieved for the valve opening degree of the electronic control thermostat, and the electronic control fan is connected with the output end of the ECU so that electronic control can be achieved for the rotating speed of the electronic control fan. The intelligent thermal management system for the diesel is simple and reasonable in structure, electronic control is achieved for the main parts such as the water pump, the thermostat and the fan of the intelligent thermal management system, the water temperature can rapidly rise to the temperature close to the target temperature after the diesel is started by calibrating the electronic control strategy, the diesel warming time is shortened, accurate water temperature control is achieved, the service life of the diesel is prolonged, and oil consumption and emission of the diesel are reduced.

Description

technical field [0001] The invention relates to the field of diesel engine cooling systems, in particular to an intelligent thermal management system for diesel engines. Background technique [0002] The diesel engine cooling system is mainly composed of water pumps, thermostats, fans, radiators, etc. The existing technical scheme of the diesel engine cooling system is that the water pumps, thermostats, and fans in the cooling system are all mechanically controlled structures. If it is fixed, the temperature of the cooling system cannot be precisely controlled according to the actual working conditions of the diesel engine and the changes in the environmental state. With the changes in the working conditions of the diesel engine and the environmental state, the cooling temperature of the diesel engine is often too high or too low, which affects the working life of the diesel engine and the diesel engine. Both fuel consumption and emissions are adversely affected. Contents ...
