ABSTRACT:
A device for vaporizing liquid fuel for increasing burn efficiency within an internal combustion engine has been provided. Fuel is injected by means of a fuel injector (I) in timed sequence without the presence of air into a closed vacuum chamber (C) wherein the droplets of fuel are immediately changed to gaseous form. A pressurized oil lubrication system lubricates the piston walls and provides a vapor barrier within a rolling piston vacuum pump (P). Heat exchange means (H,H') are provided to maintain the temperature of the gaseous fuel substantially constant and at a lower vapor point to minimize recondensation as it is supplied to the intake manifold of the internal combustion engine. Control means (U) are provided to adjust both the frequency and duration of the injection liquid fuel droplets into the vacuum chamber (C).
