Abstract
A four-stroke internal combustion engine includes variable geometric compression ratio, electrically operated inlet valves and a device for supplying a homogeneous fuel/air mixture to the engine cylinders. The inlet valves and the compression ratio are controlled by a control unit, so that the fuel/air mixture, within a lower engine rpm range, is compressed to self-ignition.
