Embodiment Construction

[0113] figure 1 An internal combustion engine according to the invention is shown in a schematic illustration with a combustion engine 10 in the form of a plurality of cylinders 12 . The cylinder 12 together with a piston guided up and down in it and a cylinder head (not shown) define a combustion chamber in which fresh gas (mainly or possibly only air) is combusted together with fuel. In this case, fuel is injected directly into the combustion chamber by means of an injector 16 in a controlled manner via a control unit 14 (engine control unit). Combustion of the fuel-fresh gas mixture causes a cyclic up-and-down motion of the piston, which in turn is transmitted in a known manner via a connecting rod (not shown) to a crankshaft (likewise not shown), whereby the crankshaft is driven in rotation.

[0114] Fresh gas is supplied to the combustion engine 10 via a fresh gas line and for this purpose is drawn in from the surroundings via an air intake (or intake port, i.e. Ansaugmü...

Abstract

The invention relates to a compressor with a shell. The shell is provided with a flow cavity for rotatably supporting a compressor impeller and an inlet channel for connecting a compressor inlet and the flow cavity. A flow guide device is arranged in the inlet channel, and the section of the inlet channel is divided into a middle section and an edge flowing region, and the two regions are transited into the flowing cavity in an area of the inlet plane of the impeller of the compressor, and the waste gas recirculation pipeline is introduced into the edge flowing region, and the edge flow regionis closable by means of a closure means in a section upstream of the through opening of the exhaust gas recirculation duct. The flow guiding device is provided with an overflow opening in the section, in the middle of the longitudinal axis, of the flow guiding device, and at least one end section of the flow guiding device is adjacent to the axial direction of the end section of the compressor impeller. The edge flow region is closed in a closed state of the flow guide device in a closed state of the flow guide device in an area of the inlet plane of the compressor impeller, and is opened inan open state. In addition, an exhaust pipeline of the engine shell is introduced into an edge flowing region.

Description

technical field [0001] The invention relates to a compressor and an exhaust gas turbocharger with such a compressor. Furthermore, the invention relates to an internal combustion engine, in particular an internal combustion engine for a motor vehicle, comprising such a compressor. Background technique [0002] In the compressor of the internal combustion engine, the fresh gas supplied to the combustion engine of the internal combustion engine via the fresh gas line is compressed. In this case, the pressure increase (Druckanhebung) depends on the rotational speed of the compressor wheel (Verdichterlaufrad) and the mass flow of fresh gas conducted via the compressor wheel. In the direction of the surge limit (Pumpgrenze) of the compressor characteristic curve, the inflow (Anströmung) of the inlet edges (Eintrittskanten) of the impeller blades (Laufradschaufeln) is increased on the pressure side due to the reduced inflow velocity with respect to the peripheral speed, ie The oc...
