Abstract

PURPOSE:To reduce loss power by operating a valve by a cam fitted onto a crank shaft and reducing the pressure in a crank chamber. CONSTITUTION:When a piston E lowers, a cam A fitted onto a crank shaft B turns, and a valve D is shifted, and the pressure in the crank chamber reduces. When a piston E reaches bottom dead center, the cam A shifts a connecting rod C, and the valve D is shifted, and the mixed gas is supplied into a cylinder from a scavenging hole. When the piston lowers, the loss power reduces, since the inside of the crank chamber is decompressed.

うものである。[Detailed Description of the Invention] In a conventional two-stroke engine, when the piston descends to the bottom dead center, the scavenging hole does not open yet, so compression pressure is generated in the crank chamber, resulting in loss of horsepower.
Figure 1 Yamaben and Inkam (This is an attempt to reduce horsepower loss as much as possible by absorbing the pressure inside the crank chamber using a sword spring.

(The 07 connecting rod and the 2nd valve are an integral structure.
