Abstract:
1. A control apparatus for an internal combustion engine having a first fuel injection mechanism injecting fuel into a cylinder and a second fuel injection mechanism injecting the fuel into an intake manifold, comprising: a first controller controlling said internal combustion engine in a warm state so that only said first fuel injection mechanism injects the fuel to start said internal combustion engine; and a second controller controlling said internal combustion engine in a cold state so that only said second fuel injection mechanism injects the fuel to start said internal combustion engine, wherein said first fuel injection mechanism is an in-cylinder injector and said second fuel injection mechanism is an intake manifold injector, wherein the first controller controls a first fuel injection profile to the internal combustion engine that is in the warm state, wherein the second controller controls a second fuel injection profile to the internal combustion engine that is in the cold state, and wherein the first and second fuel injection profiles each determine a ratio of fuel that is injected by the in-cylinder injector to fuel that is injected by the intake manifold injector, and where the first and second fuel injection profiles are defined by at least one of an engine speed and an engine load.
