Abstract:
1. A power train system, comprising: a compressed air or gas supply; an accelerator or power switch; a compressed air or gas engine with at least one internal chamber configured for extracting energy from compressed air or gas, said engine operating in a first mode when the accelerator or power switch is engaged, and a second mode when the accelerator or power switch is not engaged, and at least three valves in communication with the internal chamber, said valves comprising an inlet valve, an equalizing valve, and a compression valve, wherein in said first mode the chamber in the compressed air or gas engine receives said compressed air or gas through the inlet valve from the compressed air or gas supply, said compressed air or gas subsequently expanding inside said chamber during an expanding power stroke and producing power via an output shaft, the equalizing valve opening at or near the end of the expanding power stroke at or near maximum chamber volume thereby allowing the chamber to normalize to or near ambient pressure, and during a return power stroke air or gas in the chamber exits through the inlet or compression valve, and further wherein in said second mode the chamber in the compressed air or gas engine receives low or ambient pressure air or gas through the inlet valve, said low or ambient pressure air or gas subsequently being compressed until reaching a threshold pressure sufficient to cause the compression valve to open and deliver the compressed air or gas to a storage tank or to the compressed air or gas supply, while the equalizing valve remains closed.
