Abstract
A gasoline distillation apparatus (12) for an engine (14) includes a heated vapor separator (22), a condenser (24), and a controller (28). The heated vapor separator (22) partially vaporizes the engine's primary fuel (16) to generate a fuel vapor (44). The condenser (24) cools the fuel vapor (44) to produce a liquid secondary fuel (18) that is more volatile than the primary fuel (16). The controller (28) determines when the engine (14) is supplied with either primary (16) or secondary fuel (18). The secondary fuel (18) is used only during an initial engine operation period, while the primary fuel (16) is used all other times. After engine operation, the primary fuel (16) is purged from the engine (14) and replaced with the secondary fuel (18) to maximize secondary fuel (18) use during the initial engine operation period.
