Abstract
A diesel fuel composition is set forth for an increased cetane number vis-a-vis conventional diesel fuel compositions. The composition generally comprises one or more compounds selected from the dialkoxy alkane (DAAK) chemical family. In a preferred embodiment of the present invention, the diesel fuel composition consists of moderate amounts of dimethoxy propane (DMPP) and dimethoxy ethane (DMET) blended into a conventional diesel fuel.
Claims5
A diesel fuel composition for increased cetane number comprising one or more compounds selected from the group consisting of:
- (a) dimethoxy propane (DMPP) as represented by CH.sub.3 --O--C.sub.3 H.sub.6 --O--CH.sub.3 ;
- and
- (b) dimethoxy ethane (DMET) as represented by CH.sub.3 --O--C.sub.2 H.sub.4 --O--CH.sub.3 wherein the concentration of the DMET in said diesel fuel composition is either:
- (i) any concentration less than 100 volume % if the DMET is used in combination with DMPP in said diesel fuel composition;
- or
- (ii) any concentration greater than or equal to 25 volume % but less than 100 volume % if the DMET is not used in combination with DMPP in said diesel fuel composition.
