Mileage improvement system for internal combustion engines

Claim 1

A mileage improvement system for internal combustion engines comprising: a set of four continually operating cylinders to supply the minimum power requirements plus 10%; a separate continuous manifold supplying the fuel air system for the four minimum sized cylinders; four larger unloading cylinders each equipped with an unloading valve and connected to a separate unloading system; the four larger unloading cylinders when coupled with the appropriate smaller cylinder meet the highest power requirements of the vehicle; an unloader valve means responsive to the vacuum variations of the minimum cylinder manifold but located in the maximum cylinder manifold and controlling a blade to shut off the maximum cylinder manifold; a special unloading manifold to divert the contents of the unloading cylinders into opposite unloading cylinders and prevent partially unburned gases and various chemicals from contact with the outside atmosphere; a set of four unloading valves, each located in one of the four maximum cylinders to release compression or exhaust into a special unloading manifold chamber; and, the maximum and minimum cylinders are coupled in pairs to achieve the maximum power and the minimum unbalance and power surge.
