Abstract

The invention belongs to the technical field of engines and particularly relates to a detection method and a detection device for clamping stagnation of a supercharger and an engine. The method includes the steps that the rotating speed of the engine is obtained; the first pressure at the position of an outlet of an air filter of the engine and the second pressure at the position of an outlet of the supercharger of the engine are obtained according to the result that the rotating speed of the engine reaches the preset rotating speed, and the first pressure difference of the second pressure andthe first pressure is calculated; the first pressure difference is compared with the first preset pressure difference; and clamping stagnation of the supercharger is judged the first time according to the result that the first pressure difference is smaller than the first preset pressure difference. By means of the detection method for clamping station of the supercharger, the first pressure difference is obtained according to the first pressure at the position of the outlet of the air filter and the second pressure at the position of the outlet of the supercharger, the first pressure difference is compared with the first preset pressure difference, and when the first pressure difference is smaller than the first preset pressure difference, clamping stagnation of the supercharger can be determined. Thus, the method capable of effectively judging clamping stagnation of the supercharger is provided.

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 supercharger sticking. Background technique [0002] The supercharger is stuck, which 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 the engine has a problem, the supercharger is generally not suspected first. It can be seen that the supercharger stuck is one of the engine failures with a certain degree of concealment. In the related art, there is no method capable of effectively judging supercharger sticking. Contents of the invention [0003] The purpose of the present invention is at least to solve the problem that currently there is no method capable of effectively judging whether the...
