Abstract
The invention relates to a turbocharger (1) in which the bearing-housing-side diffuser wall is thermally decoupled in order to reduce the heat introduction at the bearing housing cover (5). The turbocharger (1) comprises a turbine (2), a compressor (3) which has a diffuser, and a bearing housing (4) which is arranged between the turbine (2) and the compressor (3) and which has the bearing housing cover (5). Said bearing housing cover (5) is composed of a material with a low thermal conductivity of at most 5 W/mK, for example a temperature-resistant plastic.
Claims8
A turbocharger (1)
- having a turbine (2),
- having a compressor (3) which has a diffuser,
- having a bearing housing (4) which is arranged between the turbine (2) and the compressor (3) and which has a bearing housing cover (5), wherein
- the bearing housing cover (5) is formed from a material with a thermal conductivity of less than 5 W/mK.
An engine driven vehicle, including an internal combustion engine having an air inlet and an exhaust outlet, an exhaust manifold connected to the engine exhaust outlet, and a turbocharger (1) in the flow of the exhaust manifold, wherein the turbocharger comprises:
- a turbine (2),
- a compressor (3) which has a diffuser,
- a bearing housing (4) which is arranged between and is connected to the turbine (2) and the compressor (3) and which has a bearing housing cover (5), wherein
- the bearing housing cover (5) is formed from a material with a thermal conductivity of less than 5 W/mK.
