METHOD FOR IMPROVING THE OPERATION OF AN INTERNAL COMBUSTION ENGINE AND INTERNAL COMBUSTION ENGINE WITH IMPROVED OPERATION AND SIMPLIFIED STRUCTURE

摘要

Method and internal combustion engine with improved operation and short cycle. The engine of the invention is characterized in that each cylinder (1) is deprived of valve, throttle or regulator or the like so that the inlet port (6) and the exhaust port (7) are permanently freely open. Air injection means (10) continuously supply pressure air in the direction of the inlet port (6). Furthermore, the rotation angle of the crankshaft (4) during which the inlet port (6) is cleared by the piston (3) is larger than the rotation angle of the crankshaft during which the exhaust port (7) is cleared by the piston (3). Thereby, a short cycle operation, that is to say shorter than a two-stroke operation, leading to a common maximum of torque and power is obtained.
