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.

摘要： Cylinders of an internal combustion engine are divided into at least two cylinder groups. First air-fuel ratio sensors are disposed in each exhaust branch pipe connected to the cylinder groups, and a second air-fuel ratio sensor is disposed in a common exhaust pipe upstream from the catalyst. When a vapor amount introduced into an intake passage during purge control is determined, the vapor amount is determined during normal operation using output values from the first air-fuel ratio sensors and the vapor amount value learned during normal operation. During rich-lean operation, the vapor amount is determined using the output value from the second air-fuel ratio sensor and the vapor amount value learned during rich-lean operation. Thereby, the vapor amount introduced into the intake passage when a switch is made from normal to rich-lean operation of the internal combustion engine is accurately determined.
