Air inlet heating control method and device, electronic equipment and computer storage medium

Abstract

The invention provides an air inlet heating control method and device, electronic equipment and a computer storage medium, and the air inlet heating control method comprises the steps that firstly, according to the water temperature, the environment temperature, the engine oil temperature and the working temperature of a heating grid, whether a first control condition is met or not at present is judged; then, if it is judged that the first control condition is met currently, the current state of the starter relay is determined; if the current state of the starter relay is the closed state, whether a second control condition is met currently or not is judged according to the air inlet temperature and the air inlet pressure; and if it is judged that the second control condition is met at present, a heating grid relay is controlled to be started. Therefore, electric quantity loss caused by simultaneous work of the starter and the heating grid is avoided, meanwhile, the air inlet temperature in the starting process can be increased, and the starting performance can be better improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a control method, device, electronic equipment and computer storage medium for intake air heating. Background technique [0002] The starting ability of a diesel engine at extremely low temperature will directly affect the range of use of the diesel engine. In a low temperature environment, due to the low ambient temperature and low intake air temperature, the temperature of the mixed gas at the end of the compression top dead center will be low during the starting process of the diesel engine, which is not conducive to the self-ignition of the diesel engine. [0003] At present, in order to improve the starting performance of a diesel engine in a low-temperature environment, the intake air preheating method is generally used to increase the intake air temperature at start-up. In the current air intake heating control strategy, when the vehicle is powered on, the amb...

Problems solved by technology

[0004] However, due to the large internal frictional resistance and high oil viscosity when the diesel engine starts for the first time in an extremely cold environment, the voltage drop of the battery during the starter motor is generally large (the voltage drop is about 10V). Allowing the intake heating grille to work will accelerate the loss of battery power, and in severe cases will cause the starter to fail to reach the minimum speed for diesel engine starting
