摘要

The air intake channel which the air (13) is supplied at least the air/the fuel/the mixture preparation device which supplies the mixture of the lube (15) with, the crankcase internal space (12) vis-a-vis (16) with, vis-a-vis the crankcase or the cylinder by the fact that it is jointed to the crankcase or the cylinder at the same time Drive the overflow channel which at least supplies the air and the fuel by the fact that it is jointed the intake valve (8) the air intake aperture which it has (7) vis-a-vis vis-a-vis the air intake aperture (17) with, by the bracket axle (4) from the crankcase internal space, the intake valve (8) and the exhaust air valve (10) the valve which is activatedThe Drive assembly (18) with, from the crankcase internal space being the block of one or more which is another body, one small scale aisle (23, 24, 25, 26 and 27) through at least, the block of one or more which is communicated with the crankcase internal space exclusively (19, 20, 21, 21 ' and 22) the valve Drive assembly housing which it possesses (19, 20, 21, 21 ' and 22) with especially to have, each block of the valve Drive assembly housing (19, 20, 21, 21 ' and 22), in the shaft center direction of the cylinder boa furthermore the altitude advantageIt was mounted, namely, the lowest part of the crankcase compared to approaching into the combustion chamber, it possesses the lowest part which is mounted, 4 strokes engine of crankcase scavenging/oil lubricated type (1).
