Abstract

PURPOSE:To prevent reckless running of an engine in which a potentiometer acts as a sensor to detect operating variables of the engine, by automatically controlling a rotating speed of the engine to lower level when the potentiometer detects abnormal variable. CONSTITUTION:Potentiometer 100, acting as a sensor to detect position of an accelerator, is provided with operation circuit 113 which checks abnormality of potentiometer 100 and calculate injection volume. Circuit 113 is equipped with comparators 105, 106 which compare output voltage VA of potentiometer 100 with the highest limit VH and the lowest limit VL and input resultant of comparison into OR circuit 107. When signal S2 of higher level than OR circuit 107 is outout, potentiometer 100 is judged as abnormal and abnormality indicator 108 is actuated. At the same time, switch 109 is thrown into B and injection volume calculation circuit 110 of injection volume is energized with voltage VS of the same level as the voltage when an accelerator pedal is at an idling position.
