Abstract

이 발명은 재시동시에 연료분사량을 시동 횟수에 따라 다르게 하는 연료분사장치에 관한 것으로, 시동 회수를 측정하기 위한 이그니션 스위치와, 시동이 걸렸는지를 검출하기 위한 크랭크 포지션 센서와, 상기 이그니션 위치와 크랭크 포지션 센서의 출력을 입력받아 그에 따른 적정한 연료분사량을 결정하여 연료분사가 이루어지도록 제어신호를 출력하기 위한 전자제어유닛과, 상기 전자제어유닛의 제어신호를 입력받아 연료를 분사하기 위한 연료분사장치를 포함하여 구성되어 시동회수에 따라 각기 다른 비율로 연료량을 감소시켜 효율적인 연료 분사기 되어 시동이 용이하도록 하며, 효과적으로 연료량을 제어하여 연료를 절약할 수 있는 재시동시에 연료 분사량을 시동 횟수에 따라 다르게 하는 연료분사장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel injection device for varying the fuel injection amount depending on the number of startups at restart, an ignition switch for measuring the number of startups, a crank position sensor for detecting whether startup has been performed, the ignition position and the crank position An electronic control unit for receiving the output of the sensor to determine the appropriate fuel injection amount according to the output of the control signal for fuel injection, and a fuel injection value for injecting the fuel by receiving the control signal of the electronic control unit It is configured to reduce the amount of fuel at different rates according to the number of start-ups, so it is an efficient fuel injector for easy starting, and the fuel injection amount varies depending on the number of start-ups during restart, which can effectively control the amount of fuel and save fuel. Relates to a device.
