Abstract

본 발명은 연료 분사량 제어장치에 관한 것으로서, 종래의 연료 분사장치는 냉각수의 온도가 높거나 낮음에 관계없이 항상 일정한 압력으로 연료를 엔진에 분사하므로, 냉각수의 온도가 낮을때에 분사되는 연료가 엔진으로 공급되어 미연소됨으로 인해 많은 양의 유해가스가 발생되고, 또한 엔진의 성능도 저하되는 문제점이 있었다. 따라서, 상기 문제점을 해결하기 위한 본 발명은 압력 발생기와 연료 탱크 사이에 연료 리턴량을 조절하는 리턴량 조절부를 설치하고, 연료 펌프의 회전량을 조절하는 제어부를 설치하여 냉각수 온도에 따라 엔진에 분사되는 연료의 압력을 조절하여 엔진의 연소능력을 향상시킬수 있도록 한 연료 분사량 제어장치이다.The present invention relates to a fuel injection amount control apparatus, and the conventional fuel injector always injects fuel to the engine at a constant pressure regardless of whether the temperature of the coolant is high or low, so that fuel injected when the temperature of the coolant is low is applied to the engine. Due to the unburned and a large amount of harmful gas is generated, there is also a problem that the performance of the engine is also reduced. Therefore, the present invention for solving the above problems is installed between the pressure generator and the fuel tank is installed in the return amount adjusting unit for adjusting the fuel return amount, the control unit for adjusting the rotation amount of the fuel pump is injected into the engine in accordance with the coolant temperature It is a fuel injection amount control device to improve the combustion capacity of the engine by adjusting the pressure of the fuel.
