Abstract
This paper establishes the mathematical model of the piston ring’s wearing capacity for the marine diesel engine, studies the influence of the piston ring’s axial motion and radial motion to the magnetic field’s output signal, computes and analyzes the corresponding relationships of the magnetoresistive sensor’s output and the piston ring’s wearing capacity, and does the on-board experiment on the oil tanker with the 6RTA52U diesel engine. Measuring actually the magnetoresistive sensor’s output corresponding to the piston ring’s wearing capacity of the marine diesel engine confirms the correctness for the mathematical model of the wearing capacity. The research conclusions lay the technical foundation for the online monitor of the piston ring’s wear.
