The invention discloses an electronically controlled engine service test method, which includes: when the vehicle power generation system enters the load power measurement mode, acquiring the output power of the vehicle power generation system and the preset power threshold of the engine; When the first difference between the preset power threshold and the rated power of the engine is greater than or equal to the preset first difference, it is determined that the engine is faulty, and the cause of the fault is located; when the first difference is smaller than the preset When the first difference is set, calculate the second difference between the output power of the vehicle power generation system and the rated power of the vehicle power generation system; when the second difference is greater than or equal to the preset value of the vehicle power generation system When the second difference is set, it is determined that the vehicle power generation system is faulty and the service test of the electronically controlled engine is ended. Through the above method, the power of the engine and the power of the power generation system can be automatically measured, the cause of the failure can be judged, and corresponding maintenance instructions can be given.
Description
technical field [0001] The present invention relates to the technical field of electronically controlled engines, in particular to an electronically controlled engine service testing method, device, equipment and storage medium. Background technique [0002] Mining cars refer to narrow-gauge railway transportation vehicles that transport bulk materials such as coal, ore, and waste rocks in mines. During daily use, repair and maintenance, mining cars often measure the power of the whole vehicle to judge whether the engine itself or the whole Whether there is a component failure or a serious electrical failure in the generator system that causes insufficient power of the whole machine. [0003] At present, the power measurement of the whole machine requires manual operation by professionals, the operation process is complicated, the test module is expensive, and a lot of labor costs are wasted, and it is impossible to accurately locate the engine failure or the vehicle power g...
