FUEL FRACTIONAL DISTILLATION DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a fuel fractional distillation device of an internal combustion engine having a fail-safe mechanism used when a gas phase fuel becomes short.

SOLUTION: This fuel fractional distillation device 17 of the internal combustion engine comprises a fractional distillation part 19 connected to the fuel supply system 11 of the internal combustion engine 1 and fractionally distilling a fuel into a gaseous phase and a liquid phase, a gaseous phase fuel storage means 23 storing the gaseous phase fuel fractionally distilled in the fractional distillation part, and a gaseous phase fuel supply means 18 supplying the gaseous fuel of the gaseous phase fuel storage means to a specified destination. The device also comprises a storage amount acquisition means 24 for acquiring the storage amount of the gaseous phase fuel storage means and a fuel introduction means 28 for introducing the fuel of the fuel supply system to the specified destination when the means determines that the storage amount is equal to or less than a prescribed amount.
