Claim:
1. A control apparatus of an internal combustion engine which is capable of a lean burn operation and which comprises: a catalyst which is provided in an exhaust passage of the internal combustion engine and which has an oxidizing ability; a supercharger; an in-passage injection valve which injects fuel into an intake passage of the internal combustion engine; an in-cylinder injection valve which injects fuel into a cylinder of the internal combustion engine; and a variable valve apparatus which changes at least one of an opening timing of an intake valve and a closing timing of an exhaust valve of the internal combustion engine, wherein the control apparatus performs creating a valve overlap that is a state where the intake valve and the exhaust valve of the internal combustion engine are opened, completing an injection of fuel from the in-passage injection valve during a period in which the intake valve is closed, and completing an injection of fuel from the in-cylinder injection valve during an intake stroke when intake air pressure of the internal combustion engine is higher than atmospheric pressure.
