Abstract: A supercharging unit for an internal combustion engine has a high-pressure turbine which drives a high-pressure compressor so as to perform a rotational movement about a first axis and through which exhaust gas of the internal combustion engine flows, and having a low-pressure turbine which drives a low-pressure compressor so as to perform a rotational movement about a second axis and through which exhaust gas flows. The high-pressure turbine is arranged rotationally conjointly on a first shaft, and the high-pressure compressor is arranged rotationally conjointly on a second shaft, wherein the first and the second shaft are arranged parallel to one another and are arranged offset with respect to one another, wherein the first and the second shaft are mechanically operatively connected to one another such that the high-pressure compressor can be driven by the high-pressure turbine.

Abstract: A method for operating an internal combustion engine having at least one fuel injection valve for introducing fuel into a combustion chamber of the internal combustion engine, the valve being supplied with a specified current intensity in order to adjust a specified flow cross-section of a fuel fluidic connection in the combustion chamber. The maximum specified current intensity during normal operation is equal to a first current intensity and during a release operation is equal to a second, higher current intensity.

Abstract: In an internal combustion engine with two-stage register charging, comprising an exhaust gas line including a flow control valve with a first outlet tube section leading to a low pressure turbine via a high pressure turbine and a second outlet tube section leading directly to the low pressure turbine, the flow control valve includes a flap for controlling the exhaust gas flow from the internal combustion engine so as to either block the exhaust gas flow or direct the exhaust gas to the low pressure turbine selectively through the high pressure turbine or directly to the low pressure turbine or simultaneously via both paths.

Abstract: The invention relates to a fuel injection system for an internal combustion engine. The inventive fuel injection system comprises a high-pressure pump (1) for delivering the fuel from a fuel reservoir (2) and a number of fuel injectors (5) for injecting the fuel into the combustion chamber of the internal combustion engine. The system is further provided with a high-pressure fuel line (4) that links the high-pressure pump (1) with the fuel injectors (5) and that contains a high-pressure reservoir (3). A fuel return line (11) returns the fuel that was not injected by the fuel injectors (5) and a leakage line (12) returns the leakage amounts that occur at the fuel injectors (5). According to the invention the high-pressure fuel line (4), the fuel return line (11) and the leakage line (12) are combined in a common fuel line (13) which is characterized by cross-sections of flow that are separated from one another by walls and that correspond to the individual lines (4, 11, 12).
