<p>This invention pertains to a fuel-injection device, wherein a solenoid valve adjusts a fuel-injection level of the fuel-injection pump by adjusting its throttling for the fuel-injection passage to supply the fuel to a compressor. A driving pulse to drive the solenoid valve is formed taking various factors into consideration. For example, the driving pulse is composed of its segment having a large duty ratio and of its segment having a small duty ratio in order to secure a responsiveness of the solenoid valve. The driving pulse is formed on the bases of a change in electrical voltage to drive the solenoid valve, varying levels of voltage drop in a wire harness installed for every cylinder, and of varying levels of responsiveness unique with fuel-injection pumps.</p> |
