摘要： A control device for an internal combustion engine includes a fuel injection device (207, 2072) that injects a fuel in accordance with a required injection amount that is required for combustion in a combustion chamber that is performed to produce an output of the internal combustion engine (200), and a fuel property specific determination device (100, 221) that specifically determines a fuel property of the fuel injected. The control device further includes a control device (100) that performs an output correction process of controlling at least a portion of the interna! combustion engine (200) so as to correct the produced output based on a difference in the specifically determined fuel property.

摘要： The cylinders of an internal combustion engine are divided into at least two cylinder groups. First air-fuel ratio sensors (11, 12) are disposed in each exhaust branch pipe (5, 6) connected to the cylinder groups, and a second air-fuel ratio sensor (13) is disposed in a common exhaust pipe (7) upstream from the catalyst (10). When a vapor amount introduced into an intake passage (4) during purge control is determined, the vapor amount is determined during normal operation using the output values from the first air-fuel ratio sensors (11, 12) and the value of vapor amount learned during normal operation. During rich-lean operation, the vapor amount is determined using the output value from the second air-fuel ratio sensor (13) and the value of vapor amount learned during rich-lean operation. By doing this, the vapor amount introduced into the intake passage (4) when a switch is made from normal to rich-lean operation of the internal combustion engine is accurately determined.
