Abstract

The invention provides a grid icing fault processing method, a grid icing fault processing device, electronic equipment and a storage medium. The method comprises the steps of acquiring a first pressure value of a pressure sensor after inter-cooling, a second pressure value of a pressure sensor of an air inlet pipe and a temperature value of a temperature sensor of the air inlet pipe; checking whether the grid is frozen or not according to the first pressure value, the second pressure value and the temperature value; and if yes, controlling a heating relay to heat a grid. Whether the air inletheating grid is frozen or not can be automatically checked and determined according to ECU, the grid can be intermittently heated, and icing in the grid can be eliminated.

Description

technical field [0001] The present application relates to the technical field of intelligent control, and in particular to a fault handling method, device, electronic equipment and storage medium for grid icing. Background technique [0002] The intake heating grille can improve the cold start performance of the diesel engine in a low-temperature environment. It is usually installed on the intake pipe, and the position of the intake heating grille is placed before the mixing of cold and hot gases. Condensed water and ice are formed inside the grille, but because the front of the grille will be far away from the intake pipe, it will affect the heating effect of the grille on the gas in a low temperature environment, which is not conducive to the low temperature start of the diesel engine. [0003] When the vehicle is running normally, the temperature of the exhaust pipe is generally around 250°C to 350°C, and the temperature of the exhaust gas introduced from the exhaust pipe...
