Oil metering device for supplying oil to a fuel tank

摘要

A fuel tank includes a first container adapted to contain a fuel mixture, and a second container adapted to contain oil. A metering arrangement is provided for selectively delivering a measured quantity of said oil from the second container to the first container when fuel is added to the first container. The volume of the oil delivered to the first container being proportional to the volume of fuel added to the first container. A valve assembly is also provided for alternatively providing fluid communication between a metering chamber and the first container and the metering chamber and the second container and for permitting oil flow to the first container only when the fuel tank cap is removed.
