Embodiment Construction

[0023] figure 1 The structure of an embodiment of the turbocharged engine system according to the invention is shown.

[0024] The turbocharged engine system has an engine E with 4 cylinders Z, a high-pressure turbocharger 1 , a low-pressure turbocharger 9 and a diesel particulate filter DPF. For clarity, other components of engine E are in figure 1 not drawn in.

[0025] The high-pressure turbocharger 1 comprises a high-pressure turbine 2 and a high-pressure compressor 4 driven by the high-pressure turbine 2 via a shaft 3 . The high-pressure turbine inlet 1 a is communicatively connected to an exhaust manifold 6 of the engine E through a high-pressure exhaust pipe 5 . The high-pressure exhaust pipe 5 is also called a high-pressure turbine connection pipe. The high-pressure compressor outlet 4a is communicatively connected to the intake manifold 8 of the engine E through the high-pressure intake pipe 7 . An intercooler 7 a is provided in the high-pressure intake pipe 7 . ...

Abstract

A turbine housing (101) for a high-pressure turbo-charger (1) of a turbo-charger engine system for an internal combustion engine (E) comprises a low-pressure charger opening (102) for taking up a low-pressure turbo-charger (9) and a high-pressure charger opening (103) for taking up a high-pressure turbo-charger (1). A high-pressure exhaust opening (107) is attached to a corresponding flange at an exhaust manifold (6) of the engine (E) and there is a short-cut exhaust opening (109) with a high-pressure turbine by-pass valve area (17) attached to a corresponding flange at the exhaust manifold (6). An external connection opening (10c) is attached to a muffler, a waste gate valve area (20) being provided in the close vicinity of the external connection opening (10c).

Description

technical field [0001] The present invention relates to a two-stage turbocharged engine system for an internal combustion engine. Background technique [0002] Such a two-stage turbocharged engine system is disclosed in US 4930315. This turbocharged system also suffers from the difficulty of installing a diesel particulate filter on it. Typically, one places an oxidation catalyst near the engine and a diesel particulate filter under the chassis. Cars equipped with such engines have unnecessarily low performance and lose heat energy when regenerating the Diesel Particulate Filter (DPF). Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a motor vehicle with a clean and powerful engine within the framework of existing vehicle platforms. [0004] This technical problem is solved by the subject-matter of the independent claims. The respective dependent claims give various advantageous developments. [0005] The pre...
