Abstract: The invention relates to a method of control of an internal combustion engine comprising at least one electrically controlled inlet valve. To reduce hydrocarbon emissions by the cold engine, the opening of the valve is controlled in two successive phases (32, 34), the first phase (32) corresponding principally with the admission of fuel and the second phase (34) mainly corresponding with the air inlet. The opening of the valve is substantially lower during the first phase than during the second phase in order to pulverize the fuel into fine droplets during the first phase.

Abstract: In this method, during the same operating cycle of the cylinder, the following phases are carried out: an opening phase at the exhaust (OE-OF); a first opening phase at the intake (OA1-FA1); a second opening phase at the intake (OA2-FA2); a fuel injection phase (OI-FI) and a combustion phase. The exhaust closing time (FE) is between the first intake opening time (OA1) and the second intake opening time (OA2). The invention also relates to an internal-combustion engine having a cylinder which operates in accordance with such a method, and a motor vehicle provided with such an engine.

Abstract: The invention concerns a method for controlling the operation of a cylinder assembly according to which the following phases are carried out during the same operating cycle: an exhaust opening phase (L1); a first inlet opening phase (L2) during a compression phase of the piston, and; a second inlet opening phase (L3) subsequent to the first. The second inlet opening phase (L3) begins once the piston reaches a position located in the second third of the travel thereof, in an expansion phase, and the first phase (L1) is carried out entirely during the exhaust opening phase (L1). The invention also concerns an internal combustion engine that operates according to the aforementioned method, and to a motor vehicle equipped with this engine.
