Abstract
분사노즐의 동작상태만을 감지하여 연료의 분사시기와 분사량의 보정동작을 실행할 수 있도록 하여 디젤엔진의 연료 분사동작을 제어할 수 있도록 하는 분사노즐의 동작상태에 따른 분사량과 분사시기 제어장치 및 그 방법을 제공하기 위하여, 분사노즐에 형성되어 있는 니들밸브의 동작상태를 감지하여 해당하는 신호를 출력하는 분사노즐 동작상태 감지수단과; 상기 니들밸브의 동작정도를 감지하여 해당하는 신호를 출력하는 분사노즐 위치감지수단과; 상기 분사노즐 동작상태 감지수단과 분사노즐 위치 감지수단과 연결되어, 자동차의 주행상태에 따라 연료의 분사시기와 연료의 분사량을 산출하고, 상기 분사노즐 동자가상태 감지수단에서 인가되는 신호와 분사노즐 위치 감지수단에서 인가되는 신호를 이용하여 전상태에서의 분사시기와 연료 분사량을 판단하여 산출된 연료의 분사시기와 분사량을 보정하고, 연료의 분사동작을 위한 제어신호를 출력하는 엔진 제어수단과; 상기 엔진 제어수단에서 인가되는 제어신호에 따라 동작상태가 가변되어 설정되는 시간동안 연료의 분사동작을 실행하는 분사 노즐부와; 상기 엔진 제어수단에서 인가되는 제어신호를 따라 동작상태가 가변되어 상기 분사노즐부를 통해 분사되는 연료량을 분사노즐부로 압출하는 연료펌프로 이루어져 있다.Apparatus and method for controlling the injection amount and injection timing according to the operation state of the injection nozzle to detect the operation state of the injection nozzle and to control the fuel injection operation of the diesel engine by performing the correction operation of the injection time and injection amount of the fuel. In order to provide, the injection nozzle operation state detection means for detecting the operation state of the needle valve formed in the injection nozzle and outputs a corresponding signal; Injection nozzle position sensing means for sensing an operation degree of the needle valve and outputting a corresponding signal; It is connected to the injection nozzle operation state detection means and the injection nozzle position detection means, and calculates the injection timing of the fuel and the injection amount of the fuel in accordance with the driving state of the vehicle, and the signal and injection nozzle applied by the injection nozzle pupil state detection means Engine control means for correcting the injection timing and injection amount of the fuel calculated by determining the injection timing and the fuel injection amount in all states using the signal applied from the position sensing means, and outputting a control signal for the fuel injection operation; An injection nozzle unit which executes an injection operation of fuel for a set time in which an operation state is changed according to a control signal applied from the engine control means; The operation state is changed in accordance with a control signal applied from the engine control means is composed of a fuel pump for extruding the amount of fuel injected through the injection nozzle unit to the injection nozzle unit.
