Description

The present invention relates to a device for purging two-stroke internal combustion engines with the use of twin channels inclined towards each other and intersecting in front of the window entering the working cylinder, depending on the change in the amount of air; passing through each of the pair of channels, forming an air stream changes the direction of its movement in the cylinder in order to improve the process of removing combustion products and increase the purity of the air intended for subsequent combustion.

In FIG. 1 shows in section a working cylinder of a double acting engine; FIG. 2 is a vertical section of a cylinder of simple action; FIG. 3rd section; FIG. 4 is a modification of FIG. 2; FIG. 5 and b - the shape of the zykulneni distribution cams.

The device is as follows: before entering the working cylinder of the window a (Figs. 1, 2 and 4)} two bent and intersecting kayal bivas are inclined: through each of the paired bivals, is regulated by valves g and spools g, g g (Fig. 1) so that spool 1 serves channels b, b;

four

and the spools are g and i

respectively, the channels in, in. The hp and 5 channels are assigned for exhaust exhaust. In the position shown in FIG. 1, the valve z is open, and the spools i and z are closed; if the spool / cam action d (figs. 1 and 5) is gradually shifted downwards, and the spools g and i, connected by a common th e, the action of paired cams d (fig. 1 and b) are shifted upwards, then the amount of air passage B, b will gradually decrease through the channels, and the amount of air passing through the upper channel b will increase and forming with the jet will begin to bend to the upper piston cover, in accordance with the direction of the channel c. To service the underside of the working cylinder, the valve z-, from the open position, moves as described, and the valves z and z must move downwards, which circumstance is ensured by the corresponding shape of the cams d. And d (Fig. 5 and b).

FIG. Figures 2 and 3 depict the cylinder nfJocToro action, with the amount of air entering channels b and c being regulated by two independent valves zi and g.

FIG. 2 provides for the use, instead of two cranes Zi and Zj, of one common crane g (Fig. 4), simultaneously regulating both channels biv.

The subject of the patent.

A device for purging two-stroke internal engines, characterized by the use of paired, oblique to each other and intersecting in front of the window of a-channels bc in front of the cylinder entering into the working cylinder, depending on the change using a crane d (Fig. 4) or taps j. Hz (Figs. 2 and 3), or spools 1, 1, D (Fig. 1), the amount of air passing through each of the paired channels forming the air flow changes the direction of the failure movement in the cylinder.
