    Abstract: Gasoline compositions and additive mixtures containing compounds having the formula ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are independently selected from hydrogen, hydrocarbyl radicals, and substituted hydrocarbyl radicals, and R.sub.4 is selected from hydrogen, hydrocarbyl radicals, substituted hydrocarbyl radicals, hydrocarbyloxy radicals, and hydrocarbyloxycarbonyl radicals, in an amount sufficient to alleviate the plugging of certain catalysts being used in an engine exhaust system to lower the amount of undesirable constituents in exhaust gas from an engine being operated on gasoline containing a cyclopentadienyl manganese antiknock.

    Abstract translation: 含有下式的化合物的汽油组合物和添加剂混合物其中R 1,R 2和R 3独立地选自氢,烃基和取代的烃基,R 4选自氢,烃基,取代的烃基,烃氧基, 和烃氧基羰基,其量足以减轻用于发动机排气系统中的某些催化剂的堵塞,以降低来自在含有环戊二烯基锰抗爆炸剂的汽油上运行的发动机的废气中的不期望成分的量。
