IC engine working according to two- and four-stroke cycles - has suction chamber connected before inlet apertures of each cylinder

摘要

The suction chamber has a space for fresh air and one for mixt., and two vanes (5,6) pivotable around a common axis or mixt. and fresh air respectively, to which is connected a rotatable control disc. The vanes are so adjustable by means of the control disc that the volumes of the suction spaces (12) for mixt. and for fresh air (13) become larger or smaller, one opposed to the other. The control disc is rotatable from the housing face surface (20) for the one vane (6) to the housing face surface (10) for the other (5). It also contains a suction hole for connecting the pump chamber (11) via the pre-chamber and the channel with the engine crank sump. USE/ADVANTAGE - As an internal combustion engine functioning in accordance with the two- and four-stroke principles minimising discharge of pollutant material in exhaust gas emissions, and providing a marked fuel economy.
