Abstract
Motor fuel composition comprising a mixture of hydrocarbons in the gasoline boiling range containing in combination a minor amount of a substituted asparagine containing the formula: ##STR1## in which R and R' each represent a secondary or tertiary alkyl or alkylene radical having from about 7 to about 20 carbon atoms and a minor amount of a cyclomatic compound having the formula: MA.sub.x B.sub.y wherein M is manganese, A is a cyclopentadienyl radical and B is an electron donating group.
Claims6
A motor fuel composition comprising a mixture of hydrocarbons in a gasoline boiling range containing from about 0.001 to 5.0 weight percent of a substituted asparagine having the formula:
- ##STR5## in which R and R' each represent a secondary or a tertiary alkyl or alkylene radical having from about 7 to 20 carbon atoms and from about 0.02 to 3.5 grams per gallon of manganese as a cyclopentadienyl manganese tricarbonyl.
An unleaded motor fuel composition comprising a mixture of hydrocarbons in a gasoline boiling range containing from about 0.001 to 5.0 weight percent of a substituted asparagine having the formula:
- ##STR6## in which R and R' each represent a secondary or a tertiary alkyl or alkylene radical having from about 7 to 20 carbon atoms and from about 0.02 to 3.5 grams per gallon of manganese as a cyclopentadienyl manganese tricarbonyl.
