Patent ID: 7962275

Claim:
A control device for an internal combustion engine, comprising: a fuel injection device 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; a fuel property specific determination device that specifically determines a fuel property of the fuel injected; a control device that performs an output correction process of controlling at least a portion of the internal combustion engine so as to correct the produced output based on a difference in the specifically determined fuel property; and a prediction device that predicts that there is a possibility that the produced output will decline or become unstable if the required injection amount is in a high injection amount region above a limit injection amount of the fuel injection device that is a maximum amount in a range of fuel injection amount properly injected while a linearity of the injection amount is secured, wherein if it is predicted that during the high injection amount region, the output corresponding to the required injection amount will decline, the control device performs the output correction process so that the output corresponding to the limit injection amount becomes an upper limit of the produced output.
