Abstract
An internal combustion engine comprises an engine body, a filter provided in an exhaust passage of the engine body and trapping particulate matter in the exhaust, and a temperature sensor detecting a temperature of gas flowing cut from the filter. A control device controlling this internal combustion engine comprises a fuel cut control pan configured to perform fuel cut control stopping a supply of fuel to a combustion chamber of the engine body and a forced ending part configured to forcibly make the fuel cut control end even if a condition for performance of fuel cut control had stood based on a trend in change of temperature of the gas temperature detected by the temperature sensor.
Claims8
A control device for an internal combustion engine, wherein
- the internal combustion engine comprises:
- an engine body;
- a filter provided in an exhaust passage of the engine body and trapping particulate matter in the exhaust;
- and
- a temperature sensor provided at the exhaust passage at the downstream side from the filter in a direction of flow of exhaust and detecting a temperature of gas flowing out from the filter, and wherein
- the control device is configured to:
- perform fuel cut control, stopping a supply of fuel to a combustion chamber of the engine body;
- and
- forcibly end the fuel cut control even if a condition for performance of fuel cut control stands based on a trend in change of temperature of the gas temperature detected by the temperature sensor when reaching a predetermined timing at which the control device determines that the trend in change of temperature of the gas temperature will switch or has switched from a decreasing trend to an increasing trend.
