A method for managing a torque applied to an output shaft of a combustion engine, the combustion engine including combustion chambers, in each of which there is mounted a piston connected to the output shaft in order to apply a torque to it, the output shaft being connected to a rotary machine associated with a management member. The method involves detecting conditions of deactivation of one combustion chamber and controlling the rotary machine so as to apply to the output shaft, prior to the deactivation of one combustion chamber, a compensating torque which tends to cause a resultant torque applied to the output shaft to tend towards a deactivation torque applied by the combustion engine to the output shaft after deactivation of the combustion chamber.

Method for managing a torque applied to an output shaft of a combustion engine when one combustion chamber is deactivated, and corresponding management system

A method for controlling, during temporary stoppage, a four-stroke combustion engine including a block delimiting cylinders which define combustion chambers equipped with pistons into which opens an intake pipe and an exhaust pipe, both provided with valves that can move between open and closed positions. The method involves detecting conditions of a temporary stoppage of the engine and commanding the exhaust valves to be kept in the closed position once the engine has gone through an intake phase during the last engine cycle prior to the stoppage.
