Title:
内燃機関の点火時期制御装置
Document Type and Number:
Japanese Patent JP3616320
Kind Code:
B2
Abstract:
An ignition time controller for an internal combustion engine is provided for setting an ignition time such that it can rapidly converge to an appropriate value in accordance with a change in intake characteristics associated with a change in cam phase in either of a uniform combustion mode and a stratified combustion mode in a direct injection type internal combustion engine having a cam phase changing mechanism. The ignition time controller comprises a required torque determining unit for determining a required torque outputted by the internal combustion engine based on an engine rotational speed and an accelerator opening, a fuel injection time determining unit for determining a time at which a fuel is injected into a cylinder, a basic ignition time determining unit for determining a basic ignition time based on the engine rotational speed and the required torque in the uniform combustion mode and based on the engine rotational speed and the fuel injection time in the stratified combustion mode, and a basic ignition time correcting unit for correcting the basic ignition time in accordance with a cam phase deviation between an actual cam phase and a target cam phase.
