Abstract
An internal combustion engine includes a filter configured to capture PM contained in exhaust gas flowing through an exhaust passage. A CPU of a control device executes a calculation process of calculating a PM deposition amount, namely an amount of PM captured in a filter, based on an operating condition of the internal combustion engine and an alcohol content rate of fuel that is supplied into a cylinder, and when the PM deposition amount exceeds a specified amount, executes a regeneration process of burning PM captured in the filter.
Claims2
An internal combustion engine control device that is applied to an internal combustion engine including a cylinder, an exhaust passage through which exhaust gas discharged from the cylinder flows, and a filter configured to capture particulate matter contained in the exhaust gas flowing through the exhaust passage, the internal combustion engine control device comprising
- a processing circuit, wherein:
- the processing circuit is configured to execute a calculation process of calculating a PM deposition amount based on an operating condition of the internal combustion engine and an alcohol content rate of fuel that is supplied into the cylinder, the PM deposition amount being an amount of the particulate matter captured in the filter;
- and
- the processing circuit is configured to, when the PM deposition amount exceeds a specified amount, execute a regeneration process of burning the particulate matter captured in the filter.
