ABSTRACT:
In an apparatus for controlling an internal combustion engine in which the quantity of air supplied to the engine is controlled to control the warming-up rotational speed of the engine, a first desired warming-up rotational speed characteritic relative to the temperature of engine cooling water and a second desired warming-up rotational speed characteristic lower in rotational speed level than the former are stored in an ROM of a micro-computer, so that, when the throttle valve is not opened during warming-up of the engine, the actual rotational speed of the engine coincides with the first desired warming-up rotational speed, while, when the throttle valve is opened during warming-up, the actual rotational speed of the engine coincides with the second desired warming-up rotational speed.
