VALVELESS GAS DISTRIBUTION MECHANISM OF THE FOUR-STROKE INTERNAL COMBUSTION ENGINE

摘要

The utility model relates to the mechanical engineering industry, more precisely to gas distribution mechanisms for piston internal combustion engines. The valveless gas distribution mechanism contains a piston cylinder head (1) with windows (7, 8 and 9) and a camshaft (3) rotating in it with a cut ( five). The cut connects alternately the window (7) of the combustion chamber (10) with the window (8) for air intake and the window (9) for exhaust gases. The size of the camshaft cut width W is made depending on its radius r in the following ratio: W = 1.4142r. The size of the width of the windows Sho inlet, outlet and combustion chamber is made equal to the size of the cut width Ш of the camshaft. The technical result is to reduce the volume of residual gases.
