Control method and device for auxiliary engine of special vehicle, storage medium and equipment

Abstract

The invention discloses a control method and device for an auxiliary engine of a special vehicle, a storage medium and equipment. The control method comprises the steps that after the auxiliary engineis started, a current environment temperature value T2 and a cooling water temperature value T3 of the auxiliary engine are read; according to the environment temperature value T2 and the cooling water temperature value T3, the corresponding warming-up time t1 of the auxiliary engine is determined, and a clutch of the auxiliary engine is controlled to be disengaged for t1 seconds for warming up;and after the engine is warmed up, the clutch is controlled to return, and the auxiliary engine is gradually adjusted from the current speed to the final target rotating speed in stages. The vehicle is warmed as required, the operation efficiency is improved, the service life of the engine is longer, meanwhile, the auxiliary engine is controlled to be adjusted to the final target rotating speed step by step from the current speed after vehicle warming is completed, the smoke intensity and noise can be effectively reduced, great benefits are achieved for improving the stress of a belt or a universal transmission shaft, and the service life of the belt or the universal transmission shaft is effectively prolonged.

Description

technical field [0001] The invention relates to the field of engine control, in particular, to a control method, device, storage medium and equipment for a special vehicle auxiliary engine. Background technique [0002] Special-purpose vehicles, such as road sweepers and sweepers, generally have auxiliary engines to provide power for operations. In order to ensure the normal operation of the auxiliary engine, there is generally a warm-up process before the auxiliary engine works. However, the existing warm-up process cannot meet the warm-up needs of different environmental conditions, such as the warm-up time in high temperature seasons Too long will reduce the operating efficiency and waste fuel consumption, and the warm-up time in the season with low temperature is not enough, which will also affect the service life of the engine and increase fuel consumption; in addition, the speed of the auxiliary engine can be directly adjusted to The target speed will bring a lot of n...
