摘要： In an engine provided with a valve lift amount variable mechanism and a center phase variable mechanism for an intake valve, a region between a region where a flow rate of an intake air passing through the intake valve reaches a sonic speed and a region where an intake air amount does not substantially change relative to a change in an opening area of the intake valve is made to be a learning region. Then, in order to resolve an error in intake air amount in the learning region, a correction value for correcting control process of the valve lift amount variable mechanism is learned. When the learning of the correction value is converged, the learning correction value is corrected with an occupied rate of the valve lift amount variable mechanism in the influence ratio between influences on the two mechanisms in relation to the error. Further, based on the error occurring in a state corrected with the learning correction value which is corrected with the influence ratio, a correction value for correcting control process of the center phase variable mechanism is learned.

摘要： A wall surface of a combustion chamber (5) of an internal combustion engine (1) is divided into a low temperature wall surface (5b) and a high temperature wall surface (5a, 6a, 15a) comprising other components, and behavior models of the fuel adhering to these wall surfaces are created. By determining the fuel ratio which vaporizes from the wall surfaces and burns, and the fuel ratio which is discharged without being burnt, in respective models according to the wall surface temperatures, particularly under transient conditions, these behavior models allow the fuel amount burnt in the combustion chamber (5) and the fuel amount discharged in the exhaust gas to be precisely known.

摘要： An engine control system for an internal combustion engine comprises a combustion system for changing over a combustion mode from a first mode such as a stratified charge combustion mode to a second mode such as a homogeneous charge combustion mode, and an EGR system for controlling an EGR flow to the engine with an EGR control valve. A controller calculates a delayed target equivalent ratio which varies gradually from a first ratio for the first mode to a second ratio for the second mode, and further calculates a modified target equivalent ratio in consideration of an amount of an EGR gas. The controller determines the combustion changeover timing by monitoring a parameter based on the modified target equivalent ratio to take account of the influence of the EGR gas.
