FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: internal combustion engine has cylindrical working chamber 1 with piston 3 sliding inside; chamber is closed by cylinder cover 4 with high pressure atomized fuel injection device 5. Engine operates according to two cycle mode with closed cleaning system passing through cylinder cover with two axially symmetrical valves with aligned axes, one of which, namely, outer intake valve 7, engages with seat 15 in cylinder cover, and the other, exhaust valve 6, has cylindrical shape with its bearing surface pressed to seat 16 formed in lower portion of intake valve 7. Intake valve opens towards working chamber and exhaust valve opens in opposite direction to limit outlet passage 8 between valves. Fuel injection device 5 gets into working chamber, in fact, in center of bushing 21 limited by cylinder cover and around which exhaust valve 6 slides. EFFECT: enlarged operating capabilities. 1 dwg |
