Two stroke internal combustion engine includes gas transfer from beneath one cylinder to above second cylinder, recovering excess pressure

摘要

The two stroke engine comprises a cylinder block (2) with two cylinders (2a,2b). Each cylinder includes a device (21a,21b) for blowing above a piston in ascent, gas issuing from beneath the other piston in descent. The provides an interactive transfer of air provided for injection, or air-fuel mixture, serving to fill the cylinder before compression. The two stroke engine comprises a cylinder block (2) with two cylinders (2a,2b) in which the displacement of pistons (8a,8b) operates with a 180 degree phase shift w.r.t. the rotation of the crank shaft. Each cylinder includes inlet (12a,12b), transfer (13a,13b) and exhaust (17a,17b) pipes. Each cylinder includes a device (21a,21b) for blowing above a piston in ascent, gas issuing from beneath the other piston in descent. The provides an interactive transfer of air provided for injection, or air-fuel mixture, serving to fill the cylinder before compression.
