Abstract
An intake manifold arrangement for internal combustion engines whereby the combustion chamber can be supercharged without the use of mechanical gears and/or pumps. A pressure chamber is mounted upon the combustion chamber and communicates with the combustion chamber and an air and fuel mixture supply. A check valve for selectively allowing the mixture to enter the pressure chamber is provided between the air and fuel supply and the pressure chamber. At the connection between the pressure chamber and the combustion chamber, an intake valve for selectively allowing the mixture within the pressure chamber to enter the combustion chamber and reenter the pressure chamber during the initial portion of the compression stroke is provided. The check valve allows the fuel and air mixture to travel therethrough into the pressure chamber and the compression chamber only during a portion of the intake stroke when a vacuum is present. An exhaust boost or scavenging arrangement is provided whereby pressurized air is selectively forced into the combustion chamber at approximately halfway between bottom and top dead center piston locations during the exhaust stroke after bottom dead center and unti…
