Problems solved by technology

[0002] With the development of internal combustion engines towards high speed, high acceleration, and heavy loads, the cylinder liner-piston assembly is often damaged before reaching the design life; the most likely damage form of the cylinder liner-piston is wear, and the existing liner-piston assembly is damaged. The detection method of the wear state of the piston assembly cannot form a quantitative index reference for the wear state of the cylinder liner-piston assembly, resulting in the user being unable to take timely measures, affecting the normal operation and service life of the internal combustion engine

Abstract

The invention discloses a prediction method for the abrasion state of a cylinder sleeve-piston assembly. The prediction method comprises the following steps: a, detecting the cylinder sleeve-piston assembly of an internal combustion engine for multiple times in a detection mode; b, recording detection results of the internal combustion engine cylinder sleeve-piston assembly in different abrasion states to form a reference table; c, detecting the internal combustion engine cylinder sleeve-piston assembly to be detected by using the detection mode in the step a; and d, comparing the result measured in the step C with the reference table formed in the step b to obtain the abrasion state of the cylinder sleeve-piston assembly of the internal combustion engine. Through the arrangement of the detection mode, the abrasion state of abrasion of the cylinder sleeve-piston assembly can be effectively reflected, and the method has the advantages of being high in calculation speed, high in recognition accuracy and more stable in prediction.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to a method for predicting the wear state of a cylinder liner-piston assembly. Background technique [0002] With the development of internal combustion engines towards high speed, high acceleration, and heavy loads, the cylinder liner-piston assembly is often damaged before reaching the design life; the most likely damage form of the cylinder liner-piston is wear, and the existing liner-piston assembly is damaged. The detection method of the wear state of the piston assembly cannot form a quantitative index reference for the wear state of the cylinder liner-piston assembly, resulting in the user being unable to take timely measures, which affects the normal operation and service life of the internal combustion engine. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a predictive method for dete...
