Abstract

엔진의 회전수를 설정된 주기만큼 판독하여 엔진의 회전수 변화에 따라 자동차의 상태를 판단하여 연료가 중단된 후에서 자동차의 상태 변화에 따라 강제 분사동작을 실행할 수 있도록 하여 연비와 엔진의 출력을 향상시킬 수 있도록 하기 위하여; 엔진의 회전수를 감지하여 해당하는 전기적인 신호를 출력하는 엔진 회전수 감지부와; 상기 엔진 회전수 감지부와 연결되어 강제 연료 분사중지상태인가를 판단하고, 강제 연료 분사중지 상태일 경우에 엔진의 회전수 변화율을 판단하고, 엔진 회전수 변화율이 설정된 값보다 크거나 같을 경우 강제 분사중지 동작을 중지하여 연료의 분사동작을 실행하는 엔진 제어부와; 상기 엔진 제어부와 연결되어 엔진 제어부에서 인가되는 제어신호에 따라 연료의 분사동작을 실행하는 연료 분사장치로 이루어져 있는 자동차의 연료 중단상태에서의 강제 연료 분사장치및 그 방법에 관한 것.Improves fuel economy and engine output by reading the engine speed by a set period to determine the state of the car according to the engine speed change, and to execute forced injection operation according to the state of the car after the fuel is stopped. To make it possible; An engine speed detection unit configured to detect an engine speed and output an electric signal; It is connected to the engine speed detection unit to determine whether the forced fuel injection stop state, in the case of forced fuel injection stop state to determine the engine speed change rate, if the engine speed change rate is greater than or equal to the set value forced injection An engine control unit which stops the stop operation and executes the injection operation of the fuel; And a fuel injector in a fuel stopped state of a vehicle, the fuel injector being connected to the engine control unit and performing a fuel injection operation according to a control signal applied from the engine control unit.
