Abstract

The two piston per cylinder engine for the crankshaft driven air compressor is a modified uniflow, double-opposed piston type internal combustion engine. The engine has a cylinder (10) open at both ends. There is an ignition device (19), a fuel port (13) and a fuel device (14) at the center of the cylinder (10). There are two pistons (11, 12) that power two rods (18) and two crankshafts (26). Stem gears (30), ring gears (33) or belt gears (34) synchronize the movement of the pistons (11, 12), rods (18) and crankshafts (26). The pistons (11, 12) operate the exhaust port (15), the exhaust device (16) the air intake port (17) and the air reservoir/insertion device. All of the parts are modified to accommodate the crankshaft drive air compressor.

DETAILED DESCRIPTION OF THE INVENTION
The Uniflow, Double-Opposed Piston Type Internal Combustion Engine is modified to operate the Crankshaft Driven Air Compressor. The Uniflow, Double-Opposed Piston Type Internal Combustion Engine has a cylinder(lθ) open at both ends. There is an ignition device( 1 ), a fuel port( 13) and a fuel device( 14) at the center of the cylinder( 10). There are two pistons(l 1)(12) that approach each other at the center of the cylinder(lθ) to compress the air in preparation for insertion of the fuel for firing.
When the two pistons are at their closest approximation in the cylinder(lθ) the fuel insertion device(14) delivers fuel into the cylinder(lθ) and the ignition device(19) ignites the fuel. The ignition of the fuel increases the pressure in the cylinder(lθ) between the pistons(l 1)(12) and drives the pistons apart. The pistons drive the rods(18) which turn the crankshafts(26). The synchronizing gears(30)(33)(36) force the crankshafts(26) to turn with equal velocities. The equal velocities of the crankshafts(26) force the engine rods(l 8) to move with equal and opposite velocities. The equal and opposite velocities of the engine rods(l 8) force the pistons(l 1)(12) to move with equal and opposite velocities. The equal and opposite velocities of the pistons(l 1)(12) keep the pistons at equal or symmetrical distances from the center of the engine cylinder(lθ). The symmetry of the pistons(l 1)(12) permit the pistons to operate the exhaust port(l 5) and the air intake port(l 7) without valves and valve assemblies.
The exhaust port is placed in the cylinder at a distance where more than 50%> of the potential energy of the combustion of the fuel has been converted to mechanical energy by separation of the pistons(l 1)(12).
The air intake port( 17) is placed at a distance from the center of the cylinder( 10) where exhaust of the combusted fuel through the exhaust port(l 5) has reduced the pressure between the pistons(l l)(12) to a pressure equal to or less than the pressure achieved in the Air Reservoir/Insertion Device(25).
The pistons(l l)(12) in the engine drive the engine rods(18) which drive the crankshafts(26) which drive the compressor rods(28) which drive the compressor pistons(20) . The engine pistons(l l)(12) continue to separate until the compressor pistons(20) have completed the necessary compression of air to achieve the necessary flushing of the engine cylinder(lθ). The cylinder(lθ) is lengthened sufficiently to permit complete operation of the crankshaft driven air compressor. The pistons(l l)(12), the engine rods(18), the crankshafts(26) and the engine cylinder(lθ) are all modified to conform to the needs of the crankshaft driven air compressor. The positioning of the exhaust port(15) and the air intake port(17) are modified to maximize the efficiency of the crankshaft driven air compressor.

Claims

1. I claim as my independent claim a Uniflow, Double-Opposed Piston Type Internal Combustion Engine with the cylinder(lθ) modified by extension to permit operation of the crankshaft driven air compressor. The length of the cylinder(lθ) extended sufficiently to permit operation of the crankshaft driven air compressor.
2. I claim as the first dependent claim the placement exhaust port at a distance from the center to permit greater than 50%> of the energy of the combustion of the fuel to be converted to mechanical energy before the exhaust port(15) is opened by piston two(12).
3. I claim as the second dependent claim the placement of the air intake port at a sufficient distance from the center to permit the pressure between the pistons(l 1)(12) to fall to a pressure equal to or less than the pressure achieved in the Air Reservoir/Insertion Device at the time piston one(l 1) opens the air intake port(17)
4. I claim as the third dependent claim modification of the pistons(l 1)(12), the engine rods( 18), the crankshafts(26) to permit complete operation of the compressor rods(28) and pistons(20) in the crankshaft drive air compressor.
