Remote mixture control tool with cleaning function
First Claim
1. A remote mixture control device for testing and adjusting internal combustion engines comprising:
- (a) a housing being generally rectangular and having a front, a back, a top, and a bottom, said housing also having a plenum cavity extending from the front of said housing to the back of said housing, forming an open channel through the latitudinal center of the housing, said housing also having a venturi port extending from the top of said housing into the plenum, at an oblique angle thereto;
(b) a holding tank integrally formed within said housing, said holding tank also having an inlet port for filling, at least one ventilation port, and at least one outlet port;
(c) a liquid that is stored in said holding tank for delivery from the remote mixture device into the engine;
(d) a first control valve means within said venturi port to control the flow of liquids from said holding tank through said venturi port;
(e) a hose removably connected to said tank and said valve means to enable liquids stored in said holding tank to be transported into said venturi port;
(f) a second control valve means rotatably mounted in said housing to control the latitudinal flow of air through the plenum;
(g) a third control valve means rotatably mounted within said housing, below said venturi port, downstream of said first valve means to control the flow of air through said venturi port;
(h) nozzle means removably attached to the front of said housing such that said nozzle means covers the plenum and acts to direct the liquid-air mixture from the housing.

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.
