Abstract: The present invention relates to a method for controlling an internal combustion engine having a means (16) for directly injecting fuel as well as a means (22) for admitting at least one fluid into the combustion chamber, a cylinder (12), a burned-gas exhaust means (28), and a processing and control unit (48) receiving information on at least the driver's torque demand and the engine speed (Ne), comprising a) determining the desired torque (Torque_des) corresponding in particular to driver demand; b) from this desired torque, determining a desired Indicated Mean Effective Pressure (IMEP_des) from which the parameters (Mair_sp, BGR_sp) are established to control admission of at least one fluid into the combustion chamber; and c) determining a specified value of the IMEP (IMEP_sp) from the desired IMEP and at least one magnitude linked to the fluid admitted into the combustion chamber, to define the fuel injection parameters (Mfuel_i, SOI_i, Pfuel) in the combustion chamber.

Abstract: The present invention relates to a dipped headlight for a motor vehicle, comprising a light source cooperating with a mirror in order to form an illuminating beam with a V-shaped cut-off, the mirror comprising four regions arranged side by side, a first region giving the beam its width, a second region giving the beam its range under the horizontal part of the cut-off, a third region giving the beam its range under the inclined part of the cut-off, and a fourth part giving the beam its range along the longitudinal axis of the vehicle. According to the invention, each region is joined to the adjacent region without a step, the first region of the mirror has a reflecting surface which strongly spreads the light in the lateral direction, and the second and third regions are located on the same side of the light source.
