Abstract

Method for operating an internal combustion engine, in particular a gas spark-ignition engine with prechamber ignition, wherein the prechamber is supplied from the outside with a gas mixture as a scavenging gas whose CO₂ content is subjected to open-loop or closed-loop control, and wherein hydrogen is additionally added to the scavenging gas.

Claims

1. A method of operating an internal combustion engine, in particular a gas Otto cycle engine with prechamber ignition, wherein a gas mixture is fed to the prechamber from the exterior as scavenging gas, whose CO₂ content is controlled or regulated and wherein hydrogen is additionally added to the scavenging gas.

2. A method as set forth in claim 1 characterised in that the CO₂ entirely or partially originates from the exhaust gas of the internal combustion engine.

3. A method as set forth in claim 1 characterised in that the CO₂ entirely or partially is produced in a thermochemical reactor.

4. A method as set forth in claim 1 characterised in that the hydrogen is produced by a vapor reforming process.

5. A method as set forth in claim 4 characterised in that the CO₂ is fed to the vapor reforming process from the exhaust gas of the internal combustion engine jointly with fuel.

6. A method as set forth in claim 2 characterised in that the hydrogen is produced by a vapor reforming process.

7. A method as set forth in claim 3 characterised in that the hydrogen is produced by a vapor reforming process.
