Abstract

Diesel fuel composition comprising a diesel base fuel and at least one blowing agent wherein the blowing agent is selected from ester compounds, oxalate compounds and diazene compounds and wherein the blowing agent has a solubility in diesel base fuel at 25° C. of 100 mg/kg or greater, a decomposition temperature in the range from 50° C. to 300° C. as measured by thermogravimetric analysis (TGA), and wherein the diesel fuel composition has an evaporation rate of greater than that of the diesel base fuel as measured by acoustic levitation.
