Camshaft with cams of 180 μ&ogr;&iacgr;&rgr;&egr;ς and 90 μ&ogr;&iacgr;&rgr;&egr;ς degrees with cylinder head, with a single input-output sleeve, that is used in internal combustion engines, that consists of a camshaft (1), that has cams of 180 μ&ogr;&iacgr;&rgr;&egr;ς degrees (2) that open constantly the valves in the exhaust-intake strokes, while the cams of 90 μ&ogr;&iacgr;&rgr;&egr;ς degrees (9) that open the output throttles (9) and the input throttles (8) onlyin the respective exhaust-intake strokes. The throttles block the single input-output sleeve (5) on its ends, transforming it to output sleeve and to input sleeve. Essentially, the work production cycle of Otto is modified, since it is performed only by the input-output throttles (8, 9). Adversely, the valves (6) that seal the combustion chamber (7) follow another (double) timing, since they remain constantly open in the exhaust-intake strokes, namely in the 2 4 of each complete work production cycle in an internal combustion engine. This has practically, more economic engines in manufacture and operation, reduced pollutants and better performances and it also eliminates the inertia phenomenon on the valves and it can be compared only to multi-valve engines. |
