Abstract
A method of initiating combustion in an internal combustion engine that has a main chamber (5) of variable volume into which an ignitable mixture is introduced, an auxiliary chamber (10) opening out into the main chamber and a controlled valve unit (11, 14, 15) for putting the auxiliary chamber into communication with, or isolating it from, the main chamber. The method includes controlling the controlled valve to put the auxiliary chamber into communication with the main chamber during a period that includes the top dead center between the compression stage and the expansion stage. An engine is specially adapted to implement the method.
