摘要： The invention concerns a combustion chamber delimited by a piston head having, inside a planar peripheral ring, a recess in the form of a concave bowl open towards the chamber and off-center on the piston axis (X—X) side which faces towards the injector inclined on the axis (X—X) and is laterally implanted on the cylinder head for direct injection into the chamber, and on the axis (X—X), a boss having, in layout, a horseshoe or crescent shape which partially enclosed the recess. The boss has an overhanging edge above the connection between the recess and the boss, whereof the upper surface is convex towards the chamber. The width of the overhanging edge is at its maximum in the horseshoe shaped boss base and gradually decreases until it substantially disappears at the tips of the two wings of the horseshoe-shaped boss, thereby ensuring a good preparation for the air/fuel mixture in the center of the chamber, opposite the axial plug at the chamber top. The invention is applicable to internal combustion engine with applied ignition and direct injection.

摘要： The invention concerns a direct injection internal combustion engine comprising a camshaft and at least two cylinders (1), having in each cylinder a mobile piston (2) associated with at least to intake valves (4, 5), each located in an induction pipes (8, 9), and at least an exhaust valve (6, 7). The displacement of said valves is independent of the rotation of the camshaft and is controlled by a computer (15). The induction pipes (8, 9) are designed to produce an air velocity field inside the cylinder (1) parallel to said cylinder axis. The computer (15) controls, cylinder by cylinder, the opening and closing times of said at lent two intake valves (4, 5) to adapt the shape of the air velocity field inside the cylinder (1) to the engine power.

摘要： The invention concerns an intake manifold (1) comprising a plenum (8) and air ducts (13) one of which at least, for each combustion chamber of the engine, has a sudden enlargement (19) of its passage cross-section, immediately followed in downstream direction by a duct portion (20) having a gradually decreasing cross-section and ending (21) upstream of a flange fixing (16) the manifold (1) to the engine and its cylinder head. The plenum (8) and each of the air ducts (13) at least are made of synthetic material, preferably capable of being molded. The invention is useful for equipping internal combustion engine with pistons driven in reciprocating movement in the cylinders.

摘要： A fuel injector comprising a head which has a free outer face and a main orifice designed to spray a fuel jet in a main direction and a secondary orifice designed to spray a fuel jet in a secondary direction, the main and secondary orifices opening into the outer face and communicating directly with a common injection chamber which is selectively placed in communication with a supply chamber. The secondary direction forms an angle α between 10° and 80°, with the main direction so that the secondary jet intercepts the main jet in a burst zone which starts at a distance d of between 1 and 15 mm, and the flow rate of the secondary jet is between 80% and 100% of the flow rate of the main jet. The invention also relates to a spark ignition engine and to a method of manufacturing the injector.

摘要： Separated air flow in the neighborhood of the leading edge of a butterfly valve plate in a throttle body fuel injection system can result in whistling. To alleviate the noise, a provided with an recess, or relief, on the suction side of the butterfly valve plate, near the leading edge. The recess has sides that are substantially radial lines starting at the outer periphery of the valve plate and extending toward the center of the valve plate. At their centermost ends, they are connected by a substantially straight line running parallel to the axis of rotation of the butterfly valve plate.
