ABSTRACT:
A four cycle internal combustion engine in which cylinders are arranged in pairs. The pistons in each pair of pistons are arranged to operate in tandem.
A U shaped arm which is arranged to turn around a center is connected through one set of linkages to a pair of pistons and through a second set of linkages to a crank. The center of rotation of the said U shaped arm is arranged to move around a center in a manner which will change the length of the stroke of the pistons without affecting the compression ratio.
A third "air pumping cylinder" is located midway between the two cylinders. This cylinder contains an "air pumping piston".
A cam operated rotary valve which is located in the top of the air pumping cylinder will be turned to an intake port during the down strokes of the air pumping piston and will permit air to be drawn in to this cylinder.
The rotary valve will be turned to a closed position during the up strokes of the air pumping piston. This will permit air to be compressed.
Near the top of the compression stroke, the rotary valve will be turned to a port which will conduct hot compressed air from the air pumping cylinder to a cylinder in which a fuel mixture has been compressed. This will create turbulence in this mixture and ignite this mixture.
The cycle will then repeat for the second cylinder.
