Abstract
Disclosed is a method for controlling combustion in an internal combustion engine including, on the one hand, an air inlet pipe provided with an air flow regulator in the pipe and, on the other hand, a single cylinder associated with the regulator, and including the following steps: determining the engine speed and/or load; and when the speed is below a predetermined value and/or the engine load is below a predetermined value, the air flow regulator in the inlet pipe is operated in such a way that the air flow is temporarily reduced during the engine cycle compared with the position that the butterfly-type throttle valve occupies during the other strokes of the engine cycle, while an intake valve that lets air from the inlet pipe into the corresponding cylinder is open.
