The invention relates to a device to obtain a sump-pump two stroke engine separated from the system to transform the reciprocating rectilinear motion into rotational motion of the output shaft, and relevant independent lubrication system characterised in that it is provided a separation element of the inner part of the two stroke engine, i.e. the inner volume of the assembly including head - cylinder volume of the sump occupied by the mechanism to transform the rectilinear motion of the piston into rotary motion, said separation element dividing said volume into two distinct and separated zones, respectively a warm zone and a cold zone, said warm zone being comprised of the volume physically delimited by the inner part of the head and by the head of the piston, wherein the scavenging, the eventual injection of the fuel, the combustion and the expansion occur, and by the lower part of the piston wherein the intake and the compression of the scavenging fluid occur, and a cold zone, the latter being the zone under the division or separation element wherein the mechanism to transform the motion of the output shaft is housed. |
