Abstract: On the basis of the structure of the traditional electromagnetic injector, this paper proposes a new type of electromagnetic injector structure by changing the opening mode of the control valve. Taking the fuel injection consistency and response time as the evaluation indexes, a one‐dimensional simulation model was established to compare the fuel injection performance of the traditional electromagnetic injector and the new electromagnetic injector. For the new electromagnetic injector, the structural parameters of the control valve were optimized by orthogonal analysis. The results show that: compared with the traditional electromagnetic injector, the new electromagnetic injector had better multicylinder fuel injection consistency and more stable fuel injection quantity, but the opening delay, opening time, closing delay, and injection duration were increased by 30.77%, 11.14%, 33.46%, and 0.44%, respectively. The closing time was decreased by 8.55%, which was due to the change in the force and motion of the control valve body. After optimization, the response delay time of the injector was decreased and the fuel injection consistency became better. The opening delay, opening time, closing delay, and injection duration were decreased by 10.08%, 10.03%, 14.72%, and 4.57%, respectively; the closing time was increased by 3.42%. The average injection volume was decreased by 5.57%, and the variance value of fuel injection volume was decreased by 41.03%. [ABSTRACT FROM AUTHOR]
