Abstract
Methods and systems are provided for a comprex charger. In one example, a comprex charger is integrally arranged with an electric machine and shares a cooling arrangement therewith.
Claims20
A charged internal combustion engine, comprising:
- at least one cylinder;
- an exhaust gas discharge system configured to discharge exhaust gases;
- an intake system configured to supply charge air to the at least one cylinder;
- at least one comprex charger comprising a cylindrical cellular wheel which is rotatable about a rotation axis, is arranged in a housing, and comprises a plurality of cells which extend between end faces of the cellular wheel along the rotation axis of the cellular wheel, and wherein the comprex charger comprises a liquid cooling system;
- and
- a controller with computer-readable instructions stored on non-transitory memory thereof that when executed enable the controller to adjust a rotational speed of the cylindrical cellular wheel in response to one or more of a temperature or a pressure of exhaust gas in the exhaust gas discharge system upstream of the comprex charger and a temperature or pressure of charge air in the intake system upstream or downstream of the comprex charger.
3 more elements
A system, comprising:
- an engine comprising an exhaust gas discharge system and an intake system;
- a comprex charger comprising a cylindrical cellular wheel rotatable about an axis of rotation within a housing, wherein the cylindrical cellular wheel comprises a plurality of cells extending from opposite extreme ends of the cylindrical cellular wheel;
- wherein
- the comprex charger is electrically driven via an electric machine, the comprex charger and the electric machine are configured as an integrated component;
- and
- a controller with computer-readable instructions stored on non-transitory memory thereof that when executed enable the controller to adjust a rotational speed of the cylindrical cellular wheel in response to one or more of a temperature or a pressure of exhaust gas in the exhaust gas discharge system upstream of the comprex charger and a temperature or pressure of charge air in the intake system upstream or downstream of the comprex charger.
3 more elements
A method, comprising:
- setting a rotational speed of a comprex charger arranged in a housing with an electric machine, wherein the comprex charger comprises a cellular wheel configured as a rotor of the electric machine, wherein the setting is based on one or more of a temperature or a pressure of exhaust gas in the exhaust gas discharge system upstream of the comprex charger and a temperature or pressure of charge air in the intake system upstream or downstream of the comprex charger;
- and
- adjusting the rotational speed of the comprex charger in response to a comparison between an actual EGR flow rate and a desired EGR flow rate.
