Efficient heat distribution and intelligent control method of motor truck

Abstract

The invention discloses an efficient heat distribution and intelligent control method of a motor truck. According to the method, the on-off time and the rotating speed of a moving piece are controlled intelligently through an EMS system; a temperature self-learning intelligent control method of an electronic fan clutch is added into a high pressure common rail electronic control system strategy of an engine, that is, different cooling liquid temperatures and temperature rising rates are monitored, the control over the electronic fan clutch is learned automatically in combination with the environment temperature, and thus extra cooling loss of the engine is reduced. The method adopts multiple rounds of concept and scheme design, theoretical calculation and CFD analysis, experimental verification and optimization design, on the basis that no special hardware is added, energy conservation and noise reduction of a cooling system of the motor truck are achieved and the service life of parts is prolonged through the improvement of heat exchange capacity and intelligent control, thus, system reliability is improved, and usage cost and maintenance cost of a user are reduced substantially.

Description

technical field [0001] The invention relates to a control method for improving the efficiency of a truck, in particular to an efficient heat distribution and intelligent control method for a truck. Background technique [0002] According to relevant information, about 50% of car failures come from engines, and about 50% of engine failures are caused by cooling system failures. The function of the cooling system is to ensure that the engine can work normally and reliably under any load conditions and any thermal environment conditions required by the user without causing the engine to be overcooled or overheated. In particular, the performance of the current engine is continuously enhanced, and the use of supercharged engines is gradually increasing. This type of engine is often characterized by compact structure, generally increased thermal load and mechanical load, and is more sensitive to engine cooling issues, so attention must be paid. [0003] Traditional truck cooling...
