Abstract:
A direct-injection internal combustion engine switchable between a first operation mode and a second operation mode according to an operating condition, comprising:an accelerator operation amount detector that detects an accelerator operation amount;a parameter detector that detects a parameter relating to intake air;a controller that determines an engine control amount based on at least the accelerator operation amount when the engine is in the first operation mode and determines the engine control amount based on at least the parameter relating to intake air of the engine when the engine is in the second operation mode; anda calculator that calculates a correction amount corresponding to a responding performance for changing the engine control amount, whereinthe calculator calculates the correction amount during operation of the engine in both of the first and second operating modes, andthe controller determines the engine control amount using the correction amount when the engine is operated in the second operation mode.
