FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention can be used in two-stroke engines operating on different kinds of fuel such as gasoline, kerosene, alcohol, solar oil. Proposed two-stroke internal combustion engine has cylinder with two exhaust ports, piston connected with crankshaft through connecting rod, two intake channels with valves located in cylinder head, nozzle, combustion chamber formed by piston and cylinder head, and spark plug. Control air pressure sensor and valve control device are installed in cylinder head. Each valve control device has series-mounted and mechanically coupled rocker, rod, pusher, crankshaft with eccentric and spring to return valve into initial position arranged on valve between cylinder head and rocker. Oil in crank chamber case serves to lubricate and cool cylinder walls, piston and parts of crank gear.
EFFECT: improved economy of engine, reduced toxicity of exhaust gases.
