摘要： The invention relates to an internal combustion engine with direct fuel injection comprising at least two adjacent inlet valves (1) per cylinder, a number of outlet valves (2), an essentially coaxial spark plug (3), an injection valve (4) and a piston (5,5′). The aim of the inventive engine is to provide an improved mixture preparation which is characterized by low fuel consumption and low exhaust emissions. To this end, the injection valve (4) is arranged between two of the adjacent inlet valves (1) and the section of the cylinder wall adjacent to said inlet valves (1). in addition, the piston (5,5′) has a longitudinally extended combustion chamber cavity (6), whereby the combustion chamber cavity (6) essentially extends along the front surface of the piston (5,5′) in the direction of the vertical projection of an injection stream (E) exiting from the injection valve (4). Said cavity also comprises a step (7) which essentially runs in a transversal direction.

摘要： A spark-ignition reciprocating piston engine has at least one piston cylinder, at least one inlet port arranged at an end of the cylinder, an inlet valve located at the inlet port and that is movable to open and close the inlet port, and an inlet conduit leading to the inlet port for feeding a fluid from a fuel feed to an inlet area of the inlet port. The engine includes a partition arranged within the inlet conduit which divides the inlet conduit into at least two partial conduits over at least a portion of a length of the inlet conduit between the fuel feed and the inlet area. At least one of the partial conduits is connected to the fuel feed. The partial conduits converge directly in front of the inlet port to form the inlet area. The partition is located within a plane that extends essentially transversely to an axis of the cylinder at least in the inlet area. The partition has an end edge facing the inlet area, and has at least one portion that is movable to deflect a flow of the fluid on blow-by from the inlet conduit, through the inlet port, and into the cylinder. A controllable actuation arrangement is connected to the portion for changing a distance from the end edge to the inlet port.

摘要： The invention relates to a variable valve train for reciprocating engines, in particular internal combustion engines comprising at least one cam of a camshaft that is rotatably mounted in the cylinder head. Said cam actuates a lift valve using a pulley assembly which can be displaceably guided in a sliding-block part along an adjusting inclined plane, together with a valve actuating element which is connected in series. The valve stroke can be adjusted in a variable manner in relation to the cam by the displacement of the sliding-block part and the pulley assembly is elastically pre-tensioned in relation to the cam. To achieve a sturdy valve train which exhibits uniform valve accelerations, a free travel (s) that allows an excitation movement of the pulley assembly is provided between the cam heel and the valve actuating element. The valve actuating element is configured as a two-part cam follower with a rocker action and the sliding-block part has a sliding-block guide comprising an additional excitation inclined plane for the pulley assembly.
