ABSTRACT:
The invention is an apparatus which is mountable to the two-barrel fuel mixture intake of an internal combustion engine, ordinarily eight cylinder, wherein the two intake barrels are covered with a special plenum which replaces the ordinary carburetor, this plenum having a central septum dividing it into two chambers, one of which communicates separately with each of the intake barrels, and each chamber mounting a separate carburetor with a separate fuel input, there being separately controlled valves in the fuel input lines of the two carburetors so that by cutting the fuel off to one carburetor, half of the cylinders become inoperative thus saving fuel. An opening is provided in the septum which is valved to open when it is desired to run all eight cylinders to insure pressure equalization in the intakes for all cylinders.
