Abstract

The invention belongs to the technical field of engines, and particularly relates to a method and device for monitoring engine abrasion. The method for monitoring engine abrasion comprises the following steps: acquiring engine oil consumption; acquiring fuel consumption; according to the engine oil consumption, the fuel oil consumption, calculating the engine oil consumption ratio and storing theengine oil consumption ratio; calculating the ratio of the sum of the engine oil consumption ratios in one period to the sum of the pre-stored engine oil consumption ratios in one period; and triggering an early warning device of an engine according to the ratio not smaller than a preset threshold value. According to the method for monitoring engine abrasion, the abrasion conditions of four matched sets of the engine can be monitored, checking or replacement is conducted according to the abrasion conditions, the engine is prevented from breaking down, and normal movement of the engine is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a method and a device for monitoring engine wear. Background technique [0002] Cylinder liner, piston, piston ring, and piston pin are the four sets of the engine, and the four sets are the important parts of the engine. The wear and tear of the four sets will cause oil burning, high piston air leakage, high crankcase pressure, and increased dust in the exhaust gas. However, the wear of the four sets is difficult to find without disassembling the engine. Therefore, it is difficult to predict the engine Four matching wear conditions may lead to engine failure and affect the normal use of the engine. Contents of the invention [0003] The purpose of the present invention is to at least solve the problem that it is difficult to obtain the wear and tear of the four matching parts of the engine. This purpose is achieved through the following technical solutions: [0...
