  • Patent number: 7490467
    Abstract: A gas flow enhancer for a combustion engine includes a housing, configured to receive an inlet flow of gas at an inlet pressure, and enclosing an expansion chamber. Disposed within the expansion chamber are a set of inner vanes and outer vanes, and a flow separator. The outer vanes are disposed outside the flow separator and produce an outer helical flow of the gas. The inner vanes are disposed within the flow separator and produce an inner helical flow of the gas, the inner helical flow having a higher velocity and lower pressure than the outer helical flow. The outer helical flow and inner helical flow are recombined at an outlet of the expansion chamber so as to produce an outlet laminar flow profile having a lower average pressure than the inlet pressure.
