Embodiment Construction

[0017] An internal combustion engine of the type described above is used as a motor vehicle drive unit. In the context of the present disclosure, the expression "internal combustion engine" includes diesel engines and Otto cycle engines, and also hybrid internal combustion engines utilizing a hybrid combustion process, as well as hybrid drives comprising internal combustion engines and electric machines capable of being connected according to the drive To and receive power from the internal combustion engine, or additionally output power as a switchable auxiliary drive.

[0018] In recent years, there has been a tendency to develop small, highly supercharged engines, where supercharging is the main method of increasing power, in which the air required for the combustion process in the engine is compressed. The economic significance of said engines for the automotive industry is constantly increasing.

[0019] As mentioned above, supercharging is often accomplished by using an...

Abstract

The invention discloses an exhaust gas-turbocharged internal combustion engine and the method for operating the same. In one example, a compressor includes a diffuser formed in a compressor housing downstream of an impeller of the compressor, the diffuser including guide blades mounted on a rotatable annular support of the diffuser. Further, an engine controller may adjust rotation of the annular support based on one or more engine operating conditions.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from German Patent Application No. 102015203171.3 filed on February 23, 2015, the entire content of which is hereby incorporated by reference for all purposes. technical field [0003] The present specification generally relates to methods and systems for controlling a turbocharger compressor of an internal combustion engine. Background technique [0004] Supercharging is the process of increasing the power of an internal combustion engine by compressing a portion of the air required for the combustion process before it reaches the combustion chamber of the cylinder. This is often accomplished using a device called a turbocharger consisting of a compressor and a turbine arranged on a common shaft. The hot exhaust gas flow from the cylinders is supplied to the turbine where it expands with the release of energy, as a result the shaft starts to spin. The energy supplied by the exhaust g...
