Calculation and Design of High-Speed Electromagnetic Drives for the Engine Fuel Systems with Electronic Control

Abstract

The purpose of the proposed model for calculating the high-speed electromagnetic drives is their integration into a complex model and calculation program for conjugated hydromechanical, thermophysical and electromagnetic processes used in design and optimization of the high-pressure fuel supply equipment of the modern gasoline, diesel and gas engines. The paper considers features of the high-speed electromagnetic drives functioning, and approaches used to describe the processes occurring in them are analyzed. Mathematical models of the non-stationary electrical processes powered by a booster source and of magnetization of the soft magnetic materials taking into account static and dynamic hysteresis are presented. A drive model is formulated for the conjugated problem of processes in the high-pressure fuel systems. The results obtained using models for calculating the electromagnetic drive as part of the fuel system complex mathematical model are compared with experimental data and 3D simulation in the ANSOFT Maxwell environment. This comparison confirms reliability of the proposed model. Design of a control valve drive for the high-pressure fuel pump of a medium-speed engine is described. Features of calculation and design of the high-speed drives are considered, including the influence of elevated temperature, dynamic hysteresis and complete demagnetization at the end of the process. A conclusionis made about the proposed model efficiency in tasks of analyzing and creating the high-speed drives with the response time of 0.1 ms for fuel systems of the electronically controlled engines
