Optimization Design of Diesel Fuel Injection Pump Phase Using Timing Belt
In order to improve the reliability of the diesel engine timing system,this article analyzes the im-pact of the installation phase of the high-pressure oil pump on the timing system in diesel engines using timing belts.A study was conducted on the installation phase of the high-pressure oil pump for a certain 3L displace-ment diesel engine.The AVL multi body dynamics software Excite Timing Drive was used to conduct dynamic simulation analysis of the timing system,and parameters such as the swing angle and belt amplitude of the timing tensioner under the optimal phase of the high-pressure oil pump were confirmed.These parameters were verified through comparative experiments.The results show that under the optimal phase,the high-pressure oil pump can effectively avoid the periodic torque superposition of the timing system,minimize the torque and impact borne by the timing system,and improve the reliability of the timing belt.
