Control device for internal combustion engine |
| abstract |
The present invention relates to a control device for an internal combustion engine. The subject is to detach the ash content adhering to the collector from the collector in a low temperature region. The internal combustion engine includes an internal combustion engine main body, a trap provided in an exhaust passage of the internal combustion engine main body to trap particulate matter in the exhaust gas, and a catalyst device provided in the exhaust passage upstream of the trap in the exhaust gas flow direction. A control device for controlling an internal combustion engine includes a carbon dioxide concentration control for reducing a carbon dioxide concentration in exhaust gas flowing into the trap when the temperature of the trap is equal to or higher than a predetermined first set temperature and lower than a second set temperature department. The first set temperature is set to be selected from a temperature range in which ash adhering to the trap can be detached from the trap when the trap is in an atmosphere where the carbon dioxide concentration is lower than that in the exhaust atmosphere. temperature. The second set temperature is set to prevent overheating of the catalyst device. |
