Horizontal 4-stroke Compressed Air Engine
August 1st, 2009 | 
Author:
This engine uses a valve of my own design to emulate a 4 stroke action, much like an internal combustion engine. However, this engine runs on Air. The intake valve is a standard poppet valve like an automobile engine uses. However, instead of a cam actuated exhaust valve, the engine uses a sliding piston in the head. When the intake valve is closed, a spring pushes the piston valve right and allows air out (and in) of the cylinder through the exhaust port. When the intake valve opens, the incoming pressurized air pushes the sliding piston to the left, closing the exhaust port and directing the input air to the cylinder where it pushes the piston down. A cam, which runs at 1/2 the speed of the crankshaft, admits air for a power stroke every other revolution of the crankshaft. The flywheels are about 3″ in diameter, the bore is 3/4″ and the stroke about an inch.

Building a Custom Valve Air Cannon for ~$50
UPDATE: I stepped the 1/4″ ball valve up to a 1/2″ valve to allow faster release of back pressure. The construction process and design of a coaxial piston cannon. 2″ diameter chamber and 1″ barrel, perfect for C-cell batteries. A massive video I know. I guess building a cannon and explaining the design in one go takes some time. Some test firing to come in a week or so. Still very cold weather here.
