Analysis of Engine Exhaust Pressure Wave Performance
摘要
By analyzing the form of pressure wave within automotive exhaust system and relationship between propagation process and working condition of engine, simulate a work cycle for purpose of timely diagnosing troubles, thus presenting exhaust stroke of four cylinders through pressure wave; modifying of the speed of engine will affect the amplitude of pressure wave, harmonic components, phase position and other parameters; at the end of the exhaust stroke, exhaust pressure wave generates interference, superposition and negative effect, which is of great importance for analysis and diagnosis of engine troubles by using exhaust pressure wave.
