System for discharging water from crank chamber

摘要

A system for discharging water from a crank chamber of a two-cycle engine of a compression-type crank chamber including a water discharge passageway for connecting a bottom portion of the crank chamber with an outside area, a first valve and a second valve mounted in the water discharge passageway, and an operating member for manually opening and closing the second valve. The second valve is located downstream of the first valve and the first valve is adapted to be brought to an open position by a positive pressure in the crank chamber.
