Abstract
PURPOSE: To carry out starting excellently, feeding back signal of oxygen concentration in the exhaust gas, by installing switch to change over the transmitting signal to the control equipment to be in the theoritical air fuel ratio usually, concentrating the air fuel ratio at starting.
CONSTITUTION: The oxygen concentration in the exhaust gas is detected by O2 sensor without indication in the drawing, the signal is inputted to the first comparator 18 from 16, 17, the detecting signal and setting signal are compared with comparing integral circuit 19. The signal is inputted to the second comparator 21, the standard wave signal from standard wave generator 20 composed of constant voltage resistor 24, condenser 28 comparator 25, 26, memory circuit 30 and change- over switch 33 is inputted, main and slow solenoid drive circuit 22, 23 are controlled to set O2 concentration in the prescribed range. The changing-over to rich or lean is carried out with the changing-over switch 33.
