Method of preparing a combustible mixture in an internal combustion piston engine

Claim 1

In a method of preparing an enhanced combustible mixture for an internal combustion piston engine, having a cylinder with a cylinder head, a piston movable in said cylinder between a bottom dead center position and a top dead center position, a working space defined by the surfaces of the cylinder, of the piston and of the cylinder head, said engine being controlled by timing means and operable through cyclical strokes which include intake, compression, combustion and exhaust, the improvements which comprise the steps of: connecting said working space to a source of air before said compression stroke; producing a mixture of exhaust gases and atomized fuel droplets and supplying said exhaust gas and fuel mixture to a storage space closely adjacent to but separate from said working space of the engine; then during said compression stroke in the working space, providing for a laminar inflow of air by virtue of positive displacement of the fuel and exhaust gas mixture in the storage space and compressing the same so that the mixture maintains a non-combustible chemical composition in said storage space during said compression stroke; and as said piston approaches said top dead center position which terminates said compression stroke, applying said mixture with said air flow to produce a sudden pressure increase in said storage space causing immediate pumping into said working space of said mixture of fuel and air for subsequent combustion therein.
