ABSTRACT:
A method controls the intake and/or the exhaust of at least one deactivated cylinder (10, 12, 14, 16) of an internal-combustion engine operating in four phases. The cylinder includes an intake with an intake valve (28), an exhaust with an exhaust valve (34), a fuel injector (42), an ignition (48) and a piston sliding within this cylinder between a position corresponding to its top dead center (PMHa, PMHd) and a position corresponding to its bottom dead center (PMBa, PMBd). When the engine runs at low or partial loads, one of the valves (28, 34) of the deactivated cylinder is opened in the vicinity of a top dead center (PMHa, PMHd). This valve is closed in the vicinity of the next top dead center (PMHd, PMHa).
