Abstract

PURPOSE: To prevent a hazard of overrun of the like and protect an engine from damage, by detecting abnormality of a controller further stopping the engine at an abnormal state.
CONSTITUTION: A servomotor is controlled in accordance with a fuel injection quantity control signal OS4 by a servo signal S1 output from a servo circuit 18. Accordingly, correlation disappears between an accelerator pedal and fuel injection quantity. That is, optimum control of the accelerator pedal is performed by the control signal OS4 with calculation of te fuel injection quantity by an arithmetic unit 27. While the signal of a potentiometer connected to the servomotor shows the position of a sleeve to become a signal IS9. While a fuel shutoff valve is controlled by a fuel shutoff control signal OS5, and an engine is stopped by closing to shutoff a suction port 37.
