ABSTRACT:
An operation control system for an internal combustion engine includes a mechanically connecting device connecting between an accelerator pedal and a throttle valve and operable such that an amount of change in the valve opening of the throttle valve relative to a change in the stepping amount of the accelerator pedal is smaller in a smaller stepping amount region than in a larger stepping amount region. A throttle valve opening sensor is adapted to generate as actual throttle valve opening an output signal directly proportional in valve to a stepping amount of the accelerator pedal. A control unit is responsive to the output signal from the throttle valve opening sensor for controlling an operating amount of the operation control system. The system thus permits fine adjustment of the intake air quantity supplied to the engine in a low load region and can accurately sense the throttle valve opening during operation of the engine in the low load region, to thereby achieve improved driveability of the engine at acceleration, etc.
