Patent
·
OSTI ID:6974780
A fuel composition is described for an internal combustion engine comprising: (a) a major portion of a fuel containing (i) a C/sub 1/-C/sub 2/ alcohol and (ii) 0-50 volumes of gasoline per volume of alcohol; and (b) from about 0.003 to about 10.0(w)% of, as a wear-inhibiting additive, a condensate product of the process comprising: (i) reacting a dibasic acid anhydride with a polyoxyisopropylenediamine; (ii) reacting the maleamic acid with an N-alkyl-alkylene diamine at about 60/sup 0/ to 100/sup 0/C for about 0.1 to 10.0 hours, thereby forming a condensate product; and (iii) recovering the condensate product.
