PROCEDE ET DISPOSITIF DE COMMANDE DE SOUPAPE AVEC PLUSIEURS PHASES DE LEVEE, PROCEDE D'ALIMENTATION D'UN MOTEUR

摘要

The method involves bringing an inlet valve of a heat engine in opening position, and maintaining the valve in intermediate position i.e. between closing and opening position, to control the valve. The valve is brought and maintained at determined durations according to fuel load to be introduced in cylinders. The durations are determined such that the valve is brought to a closing position approximately during the starting of fuel compression time following the inlet time. Independent claims are also included for the following: (1) a device for controlling a valve between closing and opening positions (2) a method for supplying oxidant of a cylinder during an inlet time by displacing a inlet valve between a closing and opening positions.
