Process for improving the functioning of a short-cycle internal combustion engine, and internal combustion engine with improved short cycle functioning and simplified structure

摘要

This engine is characterised in that each cylinder 1 is devoid of valves, throttles or regulators or similar devices so that the inlet port 6 and the exhaust port 7 are permanently freely open. Air injection means 10 constantly feed air under pressure towards the inlet port 6. In addition, the angle of rotation of the crankshaft 4 during which the inlet port 10 is cleared by the piston 3 is greater than the angle of rotation of the crankshaft during which the exhaust port 7 is cleared by the piston 3. Short cycle functioning is thereby obtained, that is to say less than two strokes resulting in maximum torque and power output which coincide. <IMAGE>
