ABSTRACT:
A mixture control device is disclosed that is used to test internal combustion engines. The device is usually temporarily installed on an engine to test catalytic converters, to clean internal engine parts, or to determine specific operating problems with an engine. The device can also be used as a teaching aid to show different operating conditions without making permanent or difficult adjustments. The device can also be used in racing applications to allow a driver to adjust the mixture of an engine, while on the course, to ensure peak efficiency under varying race conditions. The device consists of a housing that has a plenum formed within its center. The plenum runs the entire length of the housing. A venturi port is also formed on the housing and it feeds fuel and air into the plenum for injection into an engine. Fuel is supplied through an internal tank and is supplied to the venturi port through a small hose and a needle valve assembly. The fuel tank has a two different outlet ports to allow convenient placement of the device during use. Two valves control the amount of air and air-fuel mixture that are injected into the engine. An outlet port is fastened to one end of the device to allow the user to inject the supplemental mixture into any convenient port on a vehicle.
