ABSTRACT:
An apparatus (10) to convert a four-stroke internal combustion engine to a two-stroke pneumatically powered engine. An air compressor (60) is driven using the rotation of the crankshaft (22) and compressed air is delivered through a supply line (74) to at least one holding tank (68). A supply line (76) delivers compressed air from the tank (68) through a regulator (20), which controls the pressure and volume, to the pneumatic distributor (24). A plurality of high pressure hoses (50) finally communicates the compressed air to the cylinders (86) of the engine (12) via the spark plug orifices (18). The pneumatic distributor (24) has a rotor (42) which opens gate valves (44) to supply compressed air to the cylinders (86) wherein the pistons (88) are at top dead center, making every downstroke a power stroke. The modified dual-lobed camshaft (80) operates the exhaust valves (84) so that every upstroke of a piston (88) is an exhaust stroke and exhaust freely escapes through the exhaust manifold (90).
