Abstract
In a compression stroke and an exhaust stroke, a part of a mixture in a downstream intake passage is introduced through a branch intake passage into a crank chamber . The mixture introduced into the crank chamber flows into a valve chamber 16 during the expansion stroke and the intake stroke. From which it flows back to an intake port through a circulation passage , and is eventually charged into a combustion chamber during the intake stroke. As the mixture passes through a first communicating passage which allows fluid communication between the crank chamber and the valve chamber , a gasoline component which is vaporized with comparative easy is vaporized by a heat released from a cylinder block so that the mixture is separated into the lubricating oil and gasoline components.
