ABSTRACT:
Electric signals produced in association with both a speed of movement of an acceleration pedal and an engine temperature are transmitted to a fuel injection valve in an intake system asynchronously with the running of an engine, so that an amount of fuel being injected from the fuel injection valve is increased as the speed of movement of the acceleration pedal increases and as the engine temperature is lowered. As a result, fuel is injected at a proper rate according to both the acceleration required and the engine temperature, the driving feeling during acceleration as well as a fuel consumption rate are improved, and an amount of detrimental components in the exhaust gases is lowered.
