Problems solved by technology

[0011] However, the known solutions have disadvantages in the rated power range, especially at high engine speeds, such as partial loading of the turbine wheel, resulting increased clogging behavior (Aufstauverhalten, sometimes referred to as accumulation behavior) and the The radial alternating load of the impeller

Embodiment Construction

[0057] The drawings are for conceptual illustration and are not to scale in terms of their dimensions and proportions.

[0058] figure 1 The basic configuration of the exhaust gas turbocharger assembly 1 is shown schematically in a sectional view perpendicular to the axis of rotation 11 of the impeller 6 . The illustrated turbocharger assembly 1 is an example of a turbocharger assembly 1 for a double flow, ie a turbocharger assembly 1 with two flow sections 3 , 4 . The turbocharger assembly 1 has a turbine housing 2 in which an impeller 6 is mounted on a rotatable shaft 11 . The turbocharger assembly 1 is characterized in that the two flow sections 3 , 4 are arranged one above the other and surround the impeller 6 in a helical manner at least along an arc section with different radii. In other words, the housing 2 has a helical design, wherein the flow sections 3 , 4 are separated by a radial housing wall as separating tongue 5 , and wherein the turbine wheel 6 is arranged, ...

Abstract

The invention relates to a turbocharger for high performance engine concepts. An exhaust gas turbocharger assembly 1 for a turbocharged internal combustion engine with a spiral housing 2, having at least two separated flow passages 3,4, at least one separating tongue 5 separating the adjacent flow passages, and a turbine rotor 6, wherein the separating tongue is arranged such that the end 7 of the separating tongue, said end facing the turbine rotor, is spaced from the edge 8 of the turbine rotor such that crosstalk between the flow passages in the flow direction occurs upstream of the turbine rotor, wherein a crosstalk cross section AUS is determinable depending on the distance dTT between the separating tongue end 7and the edge of the turbine rotor 8.

Description

technical field [0001] The invention relates to an exhaust gas turbocharger assembly for high-performance motor concepts. Background technique [0002] In a supercharged internal combustion engine with a multi-cylinder combustion engine, the common exhaust gas collection of the exhaust gas line, which connects the exhaust gas duct with the exhaust gas turbine, leads to exhaust gas discharged from one of the combustion chambers to the remaining combustion chambers The so-called crosstalk of the exhaust shock. High specific powers require increased de-throttling of the exhaust gas passage or reduction of push work. In this connection, extended venting control times are often used in order to achieve an early shift of the venting opening with comparable venting terminations. This can lead to undesired effects on the operating behavior, especially when the combustion engine is operated at increased load, since exhaust gas can flow back from the exhaust gas collector into the c...
