Classification: CPC F | IPC F

Claim 11:
12. The controller according to claim 1, wherein
the filter regeneration process includes a temperature raising process and an oxygen supplying process, and
the controller is configured to execute:
the temperature raising process that
stops the ignition with the ignition plug to stop combustion in the cylinder,
performs the injection of the fuel from the fuel injection valve, and
allows air-fuel mixture to flow to a catalyst without being burned in the cylinder, causing (i) the catalyst to generate heat by burning the air-fuel mixture and (ii) the heat generated by the catalyst to transfer to the filter,

after the temperature raising process is terminated, the oxygen supplying process that
stops the ignition with the ignition plug to stop combustion in the cylinder,
stops the injection of the fuel from the fuel injection valve, and
allows the air to flow to the filter to burn the particulate matter collected by the filter.
