高压共轨喷油器流量动态特性及敏感参数影响
Dynamic Flow Characteristics and Influence of Sensitive Parameters of High-pressure Common Rail Injector
摘要
Abstract
A numerical model of a high-pressure common rail injector was established based on the AMESim simulation platform.By adjusting the parameters of key components of the injector,its influ-ence on dynamic flow characteristics was studied,and sensitivity analysis was performed.The experi-mental results show that the diameter of the injector orifice,the size of the oil supply hole,and the lift of the needle valve have a significant impact on the injector flow.The main influencing factors of the injec-tor flow are different under different energizing durations of the solenoid valve:When the injector's pressure chamber is not fully opened during energizing duration,the size of the oil supply hole is the main influencing factor of the injector flow;when the injector's pressure chamber is fully opened,and the injector is in stable condition,the size of the injector hole and the lift of the needle valve are the main influencing factors.关键词
