Patent ID: 7014668

Claim:
A stable motor fuel composition for a diesel, gas-turbine or turbojet engine having reduced emission of pollutants, said motor fuel composition comprising: (a) an oxygen-containing component comprising at least two different oxygen-containing organic compounds, said oxygen-containing organic compounds comprising in total at least four different oxygen-containing functional groups comprising alcohol, ether, aldehyde, a C 4 to C 13 keto group, ester, nitrate inorganic ester, acetal, epoxide or peroxide, wherein each of said oxygen-containing organic compounds contains at least one of said oxygen-containing groups; and, optionally, (b) a hydrocarbon component, wherein the motor fuel composition is homogeneous and has the properties: (i) density at 20° C. of not less than 0.775 g/cm 3 ; (ii) cloud temperature is not higher than 0° C. at atmospheric pressure; (iii) stable at atmospheric pressure from a cloud temperature of −50° C. to an initial boiling point of 180° C.; and (iv) amounts of liquid evaporated by boiling at atmospheric pressure include: not more than 25% of the total volume of the motor fuel composition distills at temperatures no higher than 100° C.; not more than 35% of the total volume of the motor fuel composition distills at temperatures no higher than 150° C.; not more than 50% of the total volume of motor fuel composition distills at temperatures no higher than 200° C.; not less than 98% of the total volume of the motor fuel composition distills at temperatures no higher than 400° C.
