Method and system for controlling auto-ignition in an internal combustion engine

摘要

A method and system for controlling an auto-ignition in an internal combustion engine, comprises setting the closing timing of an outlet control device of a cylinder increasingly before or ahead a top dead center (TDC) during the exhaust stroke with the decreasing engine loads at the rate of a change in the closing timing per a unit change in the decreasing engine loads. This change in the closing timing increases with the decreasing engine loads. The opening timing of an inlet control device of the cylinder is set after the TDC.
