Abstract

The invention belongs to the technical field of engines, and in particular relates to a detection method, a detection device and an engine for stuck supercharger. The method includes: obtaining an engine speed; obtaining a first pressure at the outlet of an air filter of the engine and a second pressure at the outlet of a supercharger according to the result that the engine speed reaches a preset speed, and calculating the difference between the second pressure and the outlet of the supercharger. the first pressure difference of the first pressure; compare the first pressure difference with the first preset pressure difference; determine the supercharger for the first time according to the result that the first pressure difference is smaller than the first preset pressure difference A stuck occurs. The detection method of the supercharger stuck in the present invention obtains the first pressure difference according to the first pressure at the outlet of the air filter and the second pressure at the outlet of the supercharger, and compares the first pressure difference with the first preset pressure Compared with the difference, when the first pressure difference is less than the first preset pressure difference, it can be determined that the supercharger is stuck, thereby providing a method for effectively judging that the supercharger is stuck.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a detection method, a detection device and an engine for a stuck supercharger. Background technique [0002] Supercharger stuck is a form of damage to the supercharger of the engine. Specifically, it means that the impeller of the supercharger cannot rotate, so that the supercharger cannot play the role of supercharging. The supercharger of the engine is difficult to disassemble and inspect. When there is a problem with the engine, the supercharger is generally not suspected first. It can be seen that the stuck supercharger is one of the engine faults with certain concealment. In the related art, there is no method for effectively judging the stuck of the supercharger. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to at least solve the problem that there is currently no effective method for judging whether the supercharger is stuck. Thi...
