摘要
Abstract
Delayed response in high-speed solenoid valves will cause fuel injection timing misalignment and lower accuracy of cyclic fuel injection quantity.This problem results in an increase in fuel consumption and diesel engine exhaust emissions.This paper demonstrates,through multi-objective analysis and optimization of the electromagnetic valve structure,that minimizing the response delay of the valve is achievable.This paper establishes a simulation model of the electronic unit pump using AMESim software.It is proved by the experiment model accuracy.The key parameters influencing the solenoid valve response delay are predicted by the method of experimental design.The key parameters are residual air gap,spring preload,half angle of the poppet valve,the diameter of the valve rod,and the diameter of the poppet valve.Used the modeFRONTIER multi-objective multidisciplinary optimization application platform and the NSGA-Ⅱ genetic algorithm,the opening and closing response delay time as a target of multi-objective optimization,the model of electronic unit pump high-speed solenoid valve is set up.The optimized results indicate the delay time of closing the solenoid valve is reduced by 6%,the delay time of opening the solenoid valve is reduced by 17.7%,and the injection pressure peak is increased by 0.62 MPa,which improve the accuracy of the cyclic fuel injection quantity.关键词
