Document Type and Number:
WIPO Patent Application WO/2007/113959
Kind Code:
A1
Abstract:
This invention provides a fuel for premixing compression self-ignition-type engine, which uses an ET synthetic base material, has excellent ignitability in premixing compression self-ignition combustion, can maximize engine output and engine rotation region, and can improve thermal efficiency of the engine. The fuel contains the whole or a part of a fraction of which the distilling temperature is in the range of 25ºC to 210ºC in an FT synthetic base material and is characterized in that (a) the total content of hydrocarbons having a content of not more than 5% by volume is not less than 30% by volume, (b) the research octane number is not less than 60 and less than 90, (c) the HCCI index represented by a predetermined formula is not less than 20 and not more than 55, and (d) the naphthene content is not less than 0% by volume and not more than 20% by volume.
