A compressed air supply system includes an engine. The engine has at least one combustion chamber defined by a cylinder, a piston operable to reciprocate within the piston, and an injector operable to inject fuel into the cylinder. The engine further includes at least one intake valve, at least one exhaust valve, and at least one compressed air valve, all associated with the cylinder. The engine has a combustion cycle for producing power, wherein the combustion cycle includes a compression stroke, a power stroke, an exhaust stroke, and an intake stroke. The engine also has an air compression cycle for producing compressed air. The air compression cycle includes an air compression intake stroke and an air compression stroke. At least one control component is in communication with the engine and is configured to selectively control the engine to alternate between the combustion cycle and the air compression cycle. |
