Abstract

When a two-cycle engine, which has its two cylinders horizontally disposed, is idling, drainage from the bottom chamber of the crankcase to the upper bearing is diverted into the transfer passage of the upper cylinder due to increased suction in the transfer passage of the upper cylinder. As a result, drainage does not flow to the upper bearing in any significant amount at idle. However, with higher speeds of the engine, most of the drainage flows to the upper bearing because of the decreased suction in the transfer passage of the upper cylinder.
