Abstract: An internal combustion engine has a camshaft (23) which acts on inlet and outlet valves (5, 7), wherein the lift curve (EV, AV) of the inlet and outlet valves (5, 7) is determined by the shape of the cams (24, 25) of the camshaft (23). Arranged on the camshaft (23) is an additional auxiliary cam which acts on the outlet valve (7), as a result of which a phase-offset auxiliary lift curve (AVz) is imparted to the outlet valve (7).

Abstract: The invention relates to an exhaust gas turbocharger for a reciprocating internal combustion engine, which comprises an exhaust gas turbine in the exhaust gas train and a compressor in the intake train. The exhaust gas turbine has two exhaust gas flows via which exhaust gas is fed to the turbine wheel. The diameter ratio of the turbine wheel diameter to the compressor wheel diameter follows a function that depends on the working volume of the internal combustion engine.

Abstract: The invention relates to a compressor (5) in the induction tract (6) of an internal combustion engine, comprising a compressor wheel that is rotatably mounted in a compressor inlet channel (9) and that is used to compress supplied combustion air to an increased boost pressure. The compressor is also equipped with an adjustable conductor grid device (12) in the flow path to the compressor wheel, said device comprising two separate, co-operating conductor grids (27, 31), each containing a plurality of guide vanes (33, 34) that are distributed around the periphery. The flow cross-section between the guide vanes (33, 34) of the two conductor grids (27, 31) can be adjusted by means of the displacement of at least one conductor grid (27, 31).

Abstract: An exhaust gas turbocharger (1) for an internal combustion engine comprises an exhaust gas turbine and a compressor (3) which is connected to said turbine (2) by a shaft (4). The turbine (2) is configured in the form of a radial turbine (2) with a radial supply channel (5) and a radial flow entry cross-section (6) to the turbine wheel (9). A variable turbine geometry (7) is provided, enabling the cross-sectional adjustment of the radial flow entry cross-section (6). The variable turbine geometry (7) is supported between two support walls (11, 14) that are fixed to the housing. One of said support walls (14) projects into the supply channel (5) in such a way that the rear side of this support wall (14) that faces away from the variable turbine geometry (7) is at a distance from the inner wall (12) of the supply channel (5) and the exhaust gas located in the supply channel (5) can flow against said rear side.

Abstract: Disclosed is an exhaust gas turbocharger (2) for an internal combustion engine (1), comprising a compressor (5) in the intake pipe system (6) and an exhaust gas turbine (3) in the exhaust gas leg (4). The exhaust gas turbine (3) is provided with an exhaust gas collection chamber located inside a turbine housing (24). The exhaust gas of said exhaust gas collection chamber can be fed to the turbine wheel (27) via a cross section of a turbine inlet. The inventive exhaust gas turbocharger (2) further comprises an exhaust gas by-pass (31) which bridges the cross section of the turbine inlet and connects the exhaust gas collection chamber to a discharge area (28) of the exhaust gas turbine (3). The exhaust gas turbine (3) forms a pump for a gas-feeding device while a gas-feeding conduit (18, 21) that is assigned to the gas-feeding device extends into the exhaust gas by-pass (31).
