Online Monitoring of Cylinder-to-cylinder Uniformity in Diesel Engine Based on Instantaneous Rotational Speed
摘要
Abstract
Considering the situation of rotational speed changing and space limitation, a smart online monitoring system for diesel engine is designed. After sampling the signal of magnetoelectricity speed sensor, the instantaneous speed signal of the diesel engine is analyzed. Corresponding parameters are computed to estimate the fault of the diesel engine. After analyzing the parameters of 120 swatch samples in normal condition, one cylinder misfire and two cylinder misfire working conditions when the engine operates at low speed, middle speed, accelerating and high speed, it is shown that these working conditions can be distinguished effectively using these parameters. Corresponding thresholds of the parameters are also indicated to estimate the cylinder-to-cylinder uniformity.关键词
