Electromagnetic system fuel injection apparatus an internal combustion engine having an electromagnetic system fuel injection apparatus, and a drive circuit of an electromagnetic system fuel injection apparatus |
摘要 |
Using a control coil having a high response characteristic suited to valve opening and a hold coil suited to a hold to valve open during fuel injection using a small current, during the valve opening time, a high voltage is applied to the control coil suited to the valve opening operation and, during the time the valve is to be held open a low and stabilized voltage is applied to the hold coil. In a fuel injection apparatus, drive manner employed during a valve opening time and a valve hold time is optimized.
