The present invention relates to a control apparatus for an internal combustion engine. An object of the present invention is to suppress deterioration of emission and fuel consumption arising during acceleration due to an effect of an exhaust valve opening timing.An upper limit of a fuel injection quantity is set based on the exhaust valve opening timing. The fuel injection quantity is limited to the upper limit or less when the fuel injection quantity is increased during acceleration. The exhaust valve opening timing at which the upper limit is maximized is set to a relatively advanced timing in a low engine speed range, moving in the retard direction as the engine speed rises from the low engine speed range toward a mid engine speed range, and moving in the advance direction as the engine speed rises further from the mid engine speed range toward a high engine speed range.
