Claims12
A diesel fuel composition comprising from about 85 to about 95 weight percent of dimethyl ether, from 1 to about 20 weight percent of water, and from about 1 to about 20 weight percent of methanol, wherein the lowest concentration of methanol in weight percent, min. meth. conc., that is permitted in the diesel fuel composition containing a given water concentration in weight percent, water conc., is defined by the relationship
- 0≦min. meth. conc.≧0.5 (water conc.)−2.6
- and the largest concentration of methanol in weight percent, max. meth. conc., that is permitted in the diesel fuel containing a given water concentration in weight percent is defined by the relationship
- max. meth. conc.≦20−0.6.
