Embodiment Construction

[0043] figure 1 A schematic partial view of a turbocharger arrangement indicated generally at 10 is shown. The turbocharger arrangement has a housing 12 delimiting the turbocharger arrangement 10 with respect to the outside, wherein a plurality of elements of the turbocharger arrangement 10 are housed within the housing 12, which elements during operation Warm up accordingly.

[0044] The turbocharger arrangement 10 has a turbine housing 14 in which a turbine wheel 16 is accommodated, wherein the turbine housing 14 is connected to a manifold structure 18 of a (not shown) internal combustion engine and exhaust system 20. Via the manifold structure 18, the exhaust gas of the internal combustion engine is introduced into the turbine housing 14, which correspondingly drives the turbine wheel 16 in the turbine housing 14, wherein the exhaust gas of the internal combustion engine from The turbine housing 14 is exhausted via an exhaust system 20 . The turbine wheel 16 is rotatabl...

Abstract

The invention relates to a turbocharger arrangement structure for an internal turbocharger arrangement. The turbocharger arrangement for the internal combustion engine has a housing in which elements are arranged. An optical duct is formed in the housing and is assigned to at least one of the elements. The optical duct is assigned an infrared detector that is designed to detect infrared radiation from the at least one element through the optical duct to determine a temperature (T) of the at least one element.

Description

technical field [0001] The invention relates to a turbocharger arrangement for an internal combustion engine, which has a housing in which a plurality of components are arranged, and an optical channel / light guide (optischenKanal), The optical channel is formed in the housing and assigned to at least one of the elements. [0002] The invention also relates to a method for measuring the temperature of an element of a turbocharger arrangement. Background technique [0003] In the field of automotive engineering, legal requirements and customer demands lead to internal combustion engines with low fuel consumption and with ever-increasing specific engine power. This increased power density results in an increase in thermal energy that is rejected as heat loss from the combustion chamber to the cooling system, exhaust system, and ambient environment. This increased waste heat also increases the thermal load on a large number of components of the internal combustion engine and e...
