Abstract:
A method for converting conventional engines to a natural gas fueled engine by a natural gas converter comprising:a means for withdrawing compressed natural gas from a storage supply through an on-off valve and through a natural as dispenser to a main gas flow valve, combining said compressed natural gas with atmospheric air induced from an engine air cleaner thereby making an air/gas mixture, pressurizing said air/gas mixture by passing the air/gas mixture through a convergent-divergent venture; and allowing the air/gas mixture to then enter the engine manifold,wherein the flow of the compressed natural gas is regulated by the combination of valve mechanisms and a pressure-actuated diaphragm having an upper and a lower chamber,wherein a difference in pressure in said upper and said lower chamber of said diaphragm controls the opening and closing of said main gas flow valve which regulates the flow of compressed natural gas to a convergent nozzle.
