Embodiment Construction

[0028] Embodiments are provided that direct exhaust gas through a plurality of exhaust manifolds each connected to a turbocharger. figure 1 is an engine schematic diagram illustrating an example embodiment of an internal combustion engine according to the disclosure. figure 2 is a flowchart illustrating one example method that may be performed by the engine of the present disclosure.

[0029] In the context of the present disclosure, the term "internal combustion engine" includes in particular spark ignition engines, but also diesel engines and hybrid internal combustion engines.

[0030] figure 1A first embodiment of an internal combustion engine 1 is shown schematically, which is equipped with two exhaust-gas turbochargers 8 , 9 . Each exhaust-gas turbocharger 8, 9 comprises a turbine 8a, 9a and a compressor 8b, 9b arranged on the same shaft. The hot exhaust gases are expanded in the turbines 8a, 9a releasing energy, and the compressors 8a, 9a compress the charge fed to ...

Abstract

Embodiments for a turbocharged engine including two turbochargers are provided. In one example, a turbocharger engine includes two turbochargers arranged in parallel, each coupled to a separate exhaust manifold. Bypass of exhaust around both turbochargers may be provided via a single wastegate.

Description

[0001] related application [0002] This application claims priority from European Patent Application No. 11159784.5 filed on March 25, 2011, the entire content of which is hereby incorporated by reference for all purposes. technical field [0003] The present disclosure relates to a supercharged internal combustion engine having at least two exhaust-gas turbochargers. Background technique [0004] An internal combustion engine has a cylinder block and at least one cylinder head interconnected to form cylinders. In order to control the charge exchange, an internal combustion engine requires a control element, usually in the form of a valve, and an actuating device for activating said control element. The valve actuation mechanism required for valve movement, including the valve itself, is referred to as the valve drive mechanism. A cylinder head is typically used to house the valve drive mechanism. [0005] During charge exchange, the combustion gases are expelled via the...
