A Study on the Effect of Fuel Pipe Vibration and Wall Thickness on Injection Pressure Wave

摘要

The vibration and wall thickness of injection pipe are the main factors that effect on the accuracy measuring the pressure wave of fuel injection system. Some contrast-imitation tests have been done on the injection pump stand using a measurement system with a clamp-on sensor developed by the authors. Based on it, the law and the degree effected by these factors on the measured pressure and its characteristical values are studied, a method to decrease the effects of these factors on measurement result is also discussed in this pato decrease the effects of these factors on measurement results is also discussed in tis paper.
