FIELD: engines and pumps. ^ SUBSTANCE: two-stroke piston engine 10 comprises a pair of stationary opposed pistons 13, 15 fitted on one axle and liner 11 arranged to reciprocate relative to said stationary pistons. Said liner 11 constricts two spaces, each being functionally coupled with one of the pistons to constrict the chamber. First aforesaid chamber represents charge pre-intake chamber 21 with at least one intake opening 25, while second chamber makes combustion chamber 19 with at least one exhaust opening. Note here that said chambers are separated by pressure-controlled bypass valve 23. Reciprocation of liner 11 can be converted into rotation. ^ EFFECT: no need in mixing oil with fuel for engine lubrication, perfected suction and blow-off systems. ^ 11 cl, 19 dwg |
