Abstract: An air intake device of an internal combustion engine comprises a cylinder head having therein two intake ports that are adapted to connect to a cylinder of a cylinder block; and a single partition plate that extends across both the two intake ports so that each of the two intake ports is divided into first and second air passages.

Abstract: The drivetrain includes a differential mechanism having four or more input/output elements and having two degrees of freedom. The input In from an engine, the output Out to a drive shaft, and two motor-generators MGi and MGo are assigned to the elements, and one of the elements other than the element to which the output assigned is provided with brakes B. By braking the element other than the output with the brakes, a large reduction ratio can be achieved, so startability can be improved without enlarging the capacities of the motor-generators.

Abstract: A four-element, two-freedom-degree planetary gear mechanism is constructed by arraying four input/output elements of a sun gear S1, a ring gear R, a carrier C and a sun gear S2 in a alignment chart. One of the two elements R and C arrayed on the inner side is assigned to the input In from an engine whereas the other is assigned to the output Out to the drive shaft, and the two outer elements S1 and S2 are connected to motor-generators MGi and MGo, respectively. As a result, the torque for the motor-generators to bear can be made lower than the engine output, and the energy to pass through the motor-generators is made lower to improve the transmission efficiency of the drivetrain.

Abstract: During the starting, a) the temperature (T) of the engine and the pressure (P) of the fuel delivered by said pressurizing means are monitored, b) if T is below a predetermined threshold temperature (Ts), an engine starting mode is established in which the engine is started with fuel at high pressure as soon as the pressure (P) becomes higher than a predetermined threshold pressure (Ps1), and c) an engine starting mode is established where the engine is started using fuel at low pressure if T>Ts.

Abstract: The invention relates to a bipolar plate for a fuel cell comprising on at least one of its faces at least one flute able to form with the surface of an adjacent electrode at least one gas distribution channel, wherein said distribution channel has a shape or geometry such that the liquid of the biphasic flow flowing in said channel may be moved away from said electrode surface. The invention also relates to a method for preparing such a bipolar plate and to a fuel cell comprising at least one of such bipolar plates.

Abstract: Motor vehicle functional front end comprising at least one upper crossmember (2) and, at each end of the upper crossmember, a support piece (3) capable of supporting at least one lighting unit of the vehicle, characterized in that the connection between the upper crossmember and each support piece is provided by one nesting into the other, combined with a possibility of adjustment in a roughly horizontal direction perpendicular to the axis of the vehicle.

Abstract: Motor vehicle functional front end particularly comprising an upper crossmember (1). The said crossmember comprises, near to one of the ends of the said crossmember, a point of reference allowing it to be positioned on the vehicle, longitudinally and laterally, with respect to a reference point provided on a front wing of the vehicle.
