Abstract

The invention relates to the field of electric control diesel engine power control, and discloses a diesel engine air inlet grille heating control method and system.The diesel engine air inlet grille heating process is divided into a preparation stage, a preheating stage and a starting stage according to information such as the air inlet temperature, the cooling liquid temperature and the engine rotating speed when a diesel engine is started; corresponding heating control methods are adopted in different stages, the heating duration and output power of the air inlet grille heater are controlled by controlling grille heating pulse width modulation signals, the heating effect of the air inlet grille can be controlled without changing hardware products, cost is low, accurate heating of the air inlet grille of the diesel engine can be achieved, and the service life of the diesel engine is prolonged. And a better heating effect is achieved.
