Abstract
Embodiments of a pre-turbo catalyst positioned within a turbine in a turbocharger of an engine are disclosed. In one example approach, a turbocharger for an engine comprises a turbine and a catalyst substrate mounted directly within the turbine.
Claims14
A turbocharger for an engine, comprising:
- a turbine;
- and
- a catalyst substrate brick mounted directly within an inlet of the turbine, wherein a top surface of the catalyst substrate brick is positioned in the inlet a distance below an edge of a throat of the turbine at a coupling interface of the turbine with an exhaust manifold of the engine.
A turbocharger for an engine, comprising:
- a turbine;
- and
- a catalyst substrate brick mounted directly within an inlet of the turbine, wherein a diameter of the catalyst substrate brick decreases in a direction from a coupling interface of the turbine with an exhaust manifold of the engine towards the turbine.
A turbocharger for an engine, comprising:
- a turbine;
- and
- a pre-turbine catalyst substrate disposed in the turbine, the catalyst lacking a mantle and held in place via in interference fitting against interior walls of the turbine, wherein a top surface of the catalyst substrate is positioned in an inlet of the turbine a distance below an edge of a throat of the turbine at a coupling interface of the turbine with an exhaust source of the engine.
