METHOD OF CONTROLLING THE PROCESS OF COMBUSTION IN AN INTERNAL COMBUSTION ENGINE, AND ENGINE WITH MEANS FOR VARYING THE EFFECTIVE COMPRESSION RATIO OF THE CYLINDERS

摘要

Four-stroke internal combustion engine with variable geometric compression ratio, electrically operated inlet valves and means for supplying a homogeneous fuel/air mixture to the engine cylinders. The inlet valves (9) and the compression ratio are controlled by a control unit (15), so that the fuel/air mixture, within a lower engine rpm range, is compressed to self-ignition.
