Performance Test and Analysis of Crankshaft Pulley of a Four-cylinder Diesel Engine
In order to solve the problems of large vibration,poor crankshaft signal quality and difficult cold start of a four-cylinder diesel engine,a new crankshaft pulley with damping function and crankshaft signal disk is designed in this paper.The torsional vibration of crankshaft system is tested by experiment,and then the signal quality of crankshaft is measured and analyzed by oscilloscope,and the cold start performance of the whole machine is verified.The results show that the torsional vibration strength of the crankshaft system corresponding to the rubber rings with different natural fre-quencies is different,and the new scheme can solve the problem of signal loss.The results obtained in this paper can pro-vide design and test basis for other models of torsional vibration and signal quality optimization.
