Abstract
The invention relates to gas distribution in two-stroke combustion engine. In each cylinder the engine has an emission valve (3) that acts in forced way from mechanism of gas distribution, and placed in piston an intake pass-through valve (6) that falls under effect of pressure drop on piston. Under-piston compressor chamber is connected to atmosphere with placed in free way suction valve (4). At working stroke the pass through valve (6) is closed with prevailing pressure in cylinder. Pressure in compressor chamber increases, and valve (4) is closed as well. At the end of working stroke the emission valve (3) is opened, pressure in cylinder is decreased and pressure in compressor chamber exceeds it. The pass-through valve (6) is opened and fresh air comes to cylinder, with help for displacement of worked out gases. At following stroke of compression valve (3) is closed, piston goes up, with compression of fresh air, and the piston pass-through valve (6) is closed. At the same time fresh air is sucked to under-piston chamber through the suction valve (4) for following cycle. Synchronization of operation of installed in free way valves (4 and 6) is performed due to pressure drops on those, due to that flow of exhaust gases from working chamber to compressor chamber is decreased.
