Abstract
A gasoline engine has an actuating system including an in-cylinder fuel injection system and an ignition system, capable of changing over combustion between spark ignition combustion and compression autoignition combustion, and a controlling system for controlling the combustion changeover. In a transition from one combustion to the other, the actuating system is controlled to perform transient combustion such as stratified charge combustion with fuel injection on the compression stroke, or combustion with fuel injection during a valve shutoff period during which intake and exhaust valves are both closed.
