ENDOTHERMIC POLY-FUEL TWO-STROKE ENGINE WITH BIDIRECTIONAL POURING PIPES

摘要

The object of the present invention is a two-stroke endothermic engine (1), specifically designed for the reduction of polluting emissions, comprising a single transfer port (109) for the transfer of the fresh mix (MF) or fresh mix + lubricating oil (MF&O) and for the transfer of the scavenging air (AL) in the cylinder (106). Said scavenging air (AL) is of a sufficient volume to expel from the chamber (107) substantially all of the flue gases (GC) formed in the second phase (b) of "expansion-suction end" or "top dead centre" (PMS).
