Abstract
플라이휠에 부착되어 회전되는 톱니의 수를 감지하여 전기적 신호로 변환함으로써 크랭크축의 각 속도를 감지하는 센서휠과, 상기한 센서휠의 출력단자에 입력단자가 연결되어, SCV 구동용 솔레노이드를 펄스폭변조방식으로 제어함으로써 보다 세밀하게 기관의 공연비를 희박연소 상태로 유지하고, 희박연소에 의한 미점화가 발생할 경우에 이를 감지하여 공연비를 일정량 만큼 농후하게 조정함으로써 토크의 저하를 방지하는 전자제어장치와, 전원전압과 전자제어장치의 출력단자에 입력단자가 연결되어 전자제어장치로부터 출력되는 펄스폭변조 신호에 의해 SCV를 구동하는 SCV구동용 솔레노이드로 구성되어, 기관의 공연비를 거의 희박상태에 가까운 최적의 상태에서 운전되도록 하면서 기관의 미점화를 감지하여 미점화가 발생될 경우에 기관의 공연비를 적절하게 조정함으로써 토크의 급격한 변동을 방지하는 내연기관의 희박연소 제어시스템에 관한 것.The sensor wheel detects each speed of the crankshaft by detecting the number of teeth that are attached to the flywheel and converts it into an electrical signal, and an input terminal is connected to the output terminal of the sensor wheel. Electronic control device to maintain the air-fuel ratio of the engine in a lean burn state more finely by controlling in a manner, and to detect when the unignition caused by lean burn occurs, and to adjust the air-fuel ratio by a certain amount to prevent a drop in torque; The input terminal is connected to the power supply voltage and the output terminal of the electronic controller, and consists of an SCV driving solenoid that drives the SCV by the pulse width modulated signal output from the electronic controller. The engine can be operated in a state that detects unignition of the engine and, when an unignition occurs, By properly adjusting the fuel consumption relates to the lean combustion control system for an internal combustion engine to prevent a sudden change of the torque.
