Abstract
A combustion method for a supercharged four-stroke engine having at least four cylinders includes a combustion cycle during which a cylinder of the engine is in the exhaust phase while another cylinder is in the supercharged air intake phase with a burnt gas scavenging stage. The start of the exhaust phase of the cylinder in the exhaust phase is shifted in relation to the start of the burnt gas scavenging stage of the cylinder in the intake phase.
