Abstract
A fuel and lubricating oil mixing system designed primarily for two-cycle engines. Lubricating oil and fuel are stored in separate containers and mixed prior to entering the carburetor. Fuel flow is monitored by flow detector which relays information to a control unit. This unit in turn controls valves and pumps, mounted on both lubricating oil and fuel lines, in order to maintain a preferred mixture ratio regardless of engine speed or fuel flow rate. Such control ratio makes possible maximum convenience and performance with minimum engine wear.
Claims6
A system for supplying mixed fuel and oil to an internal combustion engine having a fuel tank, an oil tank, and a carburetor, comprising:
