CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE

摘要

An engine ECU executes a program including the step of detecting engine start (S100), the step of detecting, when rapid catalyst warm-up is necessary (YES in S110), the temperature of the engine coolant THW (S120), the step of estimating, when the THW is lower than a predetermined threshold value (YES in S130), the amount of fuel sticking to the wall surface of an intake port (S140) and calculating a cold-state increase correction value Q (P) for an intake manifold injector (S150), the step of changing the DI ratio r to satisfy the cold-state increase correction value Q (P) (S160), and the step of performing the rapid catalyst warm-up (S170).
