CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE |
摘要 |
A control device of an internal combustion engine performs an air-fuel ratio feedback control to set an air-fuel ratio to a target air-fuel ratio, and determines abnormality of a fuel system based on a feedback correction amount by the air-fuel ratio feedback control. The control device of an internal combustion engine includes: a double tank type oil pan including: an inner tank and an outer tank for storing oil; and a mechanism which switches between connection and disconnection of the inner tank and the outer tank; and a controller configured to control the mechanism to connect the inner tank and the outer tank in a case where the feedback correction amount is equal to or larger than a first predetermined value. Thus, it is possible to prevent the air-fuel ratio from getting rich, and it is possible to appropriately prevent the erroneous determination of abnormality of the fuel system. |

1. A control device for an internal combustion engine, which performs air-fuel ratio feedback control to set an air-fuel ratio to a target air-fuel ratio, and which determines abnormality of a fuel system based on a feedback correction amount by the air-fuel ratio feedback control, comprising:
a double tank type oil pan including: an inner tank and an outer tank for storing oil; and a mechanism which switches between connection and disconnection of the inner tank and the outer tank; and a controller configured to control the mechanism to connect the inner tank and the outer tank in a case where the feedback correction amount is equal to or larger than a first predetermined value. |
