<p>The invention concerns a two-stroke engine comprising a cylinder (1) wherein moves a piston (2), exhaust (6) and intake (7) devices and a blower (9) for blowing in the cylinder (1) a scavenging air stream, wherein an additional volume (10) communicates with the cylinder (1) through closing and opening means (11, 12) whereof the movements are controlled synchronously or out-of-shift with those of the piston (2) in the cylinder (1) such that, during the combustion/expansion phase, the burnt gases compress the air located in the additional volume (10) by penetrating therein at least partially; the air/burnt gas mixture is trapped therein under pressure; then the mixture is induced into the cylinder (1) during the intake phase.</p> |
