Abstract: The fuels contain as detergent materials (A) diamides from 12-20C fatty acids and polyamines with 2-6C and 2-4N atoms, and (B) esters from 12-20C fatty acids and ethanol- or propanolamine. Pref. they also contain (C) a steric-hindered phenol contg. bulky alkyl substits. as anti-oxidant, and (D) residual oils from nonanol and decanol synthesis by the OXO process, as solvent modifiers for (A) and (C) and upper lubricants. Amt. of (A+B) or (A+B+C) is pref. 20-2000 (50-500) ppm. Ratio of (A); (B) (C) is pref. from 1:1:8 to 8:1:1 and of (A+B+C) : (D) is from 9:1 to 1:9. The additives prevent gum and resin deposits in carburetorrs, which interfere with the fine adjustments required for complete combustion and minimum hydrocarbon and CO contents in the exhaust gases.

Abstract: The basic patent (DE2909565) specified the use of triethylammonium nitrate as a cetane number improver in diesel fuels consisting essentially of ethanol and/or ethylene oxide derivs. The present patent in addition specifies mixts. of triethyl- and diethylammonium nitrates and, if necessary, monoethyl ammonium nitrate for the same purpose. Use of the nitrates and the finished fuel are both claimed. The di- and triethyl derivs. pref. together constitute at least 70wt.% of the mixt. of ethylammonium nitrates, and this mixts. Pref. constitutes 15-25wt.% of the fuel.

Abstract: The use of polyethers of formula (I) and/or acetals of formula (II) as diesel fuels, opt. in combination with =45 vol. % ethanol and/or methanol, =30 vol. % water and/or =85 vol. % mineral diesel oil, is claimed. (where A is ethylene or 1,2-propylene; R1 is 1-8C alkyl; R2 is H or 1-4C alkyl; n = 1-5; R3 is H or 1-12C alkyl; R4 is Me or et; m = 0-5). (I) and (II) have high cetane nos. (e.g. 18-80), so that fuels with a relatively high alcohol and water content can be produced. The fuels produce very little pollutant emission and have better low-temp. stability than conventional diesel oils.

Abstract: Diesel fuels based on ethanol, ethylene glycol monoethyl ether (EGME) and/or polyethylene glycol monoethyl ethers contg. 2-4 CH2CH2O units, contain triethylammonium nitrate (I) in amt. sufficient to improve their cetane number. Addn. of (I) in amts. of 1-25wt.% increases the cetane number to >=27 for ethanol, >=24 for EGME, >=71 for triethylene glycol monoethyl ether (TGME), and >=31 for their mixts.

Abstract: Diesel fuels consist of (a) a petroleum middle distillate, suitable on its own as a diesel fuel (pref. at least 60 vol.%), (b) a smaller concn. of methanol (pref. 10-25 vol.%), and (c) aliphatic 6-20C (9-11C) alcohols, opt. etherified (pref. 5-15% of an alcohol liquid at ambient temp.). Component (c) acts as solvent for (a) and (b). The fuels make it possible to use in diesel engines at least some methanol (which can be made through synthesis gas from non-oil sources. The addn. of C gives homogeneous mixts. of relatively good ignitability.
