Process and device for controlling the air flow of an idling heat engine

摘要

A process and apparatus for controlling the air flow at the intake of a heat engine fed by fuel injection. The air flow is controlled as a function of the rotational speed of the engine, particularly in the vicinity of the rated idling speed. The control point is determined as a result of a filtering made on a value linked to the instantaneous value of the rotational speed of the engine followed by a weighted average between the filtered value and a magnitude linked to the rated idling speed.
