Use of Taguchi Method to Optimize the Operating Parameters of a High-Pressure Injector Driving Circuit
This paper develops a superior injector driving circuit for a 500c.c. motorcycle GDI engine. The POWER MOSFET component is introduced in the design of the three-pulse injector driving circuit. Experiments for the designed electric driving circuit are investigated to verify its feasibility. The experiments of the H.P. injector driving circuit are conducted for the fuel injection quantity of the H.P. injector under 80～100 bar fuel pressure, 1200～2000 μs injection pulse duration and DC 55～65V power supply voltage. PWM control is introduced to the last pulse 3A holding current for fast cut-off response time of the H.P. injector. Next, Taguchi method was used to lead the design of experiments (DOE). The fuel injection quantities were measured in the various control parameters as engine speeds, power supply voltages, injector driving currents, and fuel supply pressures by the designed injector driving circuit. Effect of these control parameters of the highpressure (H.P.) injector driving circuit on the fuel inject ion quantity are analyzed in the paper. Taguchi orthogonal array optimizes the operating parameters of the H.P. fuel injecting system. Results show that the three-pulse POWER MOSFET injector driving circuit is capable of operating stably and assure the accurate injection quantity of the H.P. injector.
