ON-BOARD FRACTIONATION SYSTEM AND METHODS TO GENERATE AN ENGINE STARTING FUEL.

摘要

A Fuel Fractionation System (FFS) and associated methods to generate and store a fuel for internal combustion engines is provided. FFS provides a distillation column assembly (31) including a distillation column (33) to distill liquid fuel to form a volatile light fraction secondary fuel. The distillation column (33) includes a vaporization module (61) to vaporize a feed fuel in the distillation column and includes a condensation module (63) to condense heavy fraction components of the vaporized feed fuel. FFS also provides a controller (71) positioned to control the vaporization of feed fuel in the distillation column (33) to thereby control the separation of the feed fuel into light fraction fuel and heavy fraction fuel components, and positioned to control the condensation of the heavy fraction components so that fuel exiting a light fraction output port (53) in the distillation column (33) is substantially light fraction fuel components by volume.
