In order to reduce the fuel consumption of commercial
vehicle and resulting CO2 emissions further, the research on
electronic integrated control based on engine operating conditions was
conducted. Taking an inline 4cylinder
common rail diesel engine as the research object, the electronic cooling system
including engine water pump and thermostat was regulated according to the
engine water temperature to warm the engine quickly and keep the optimal
temperature during the driving. In addition, the combustion process could be
improved through the optimization of VGT. The test results show that the
cooling water temperature can be controlled near the corresponding optimal
value under various conditions by the control system. The system can improve
the fuel consumption of diesel engine by about 3.51%, which verifies the
feasibility and effectiveness of intelligent control scheme.
