    Abstract: A fuel composition for spark-ignition engines consisting essentially of gasoline and a barium compound in an amount of 100 ppm or more in terms of barium metal and relative to the gasoline, said barium compound being selected from the group consisting of a barium sulfonate, a barium naphthenate, a barium alkylsalicylate and a barium .alpha.-alkylalkane monocarboxylate. Spark-ignition engines utilizing this fuel composition operate with improved characteristics relative to adhesion of carbon to the spark plugs. The exhaust from the engine does not degrade the exhaust gas purifying catalyst even when the engine is equipped with an exhaust ignition control device.

    Abstract translation: 一种用于火花点火发动机的燃料组合物,所述燃料组合物主要由汽油和钡化合物组成,其量以钡金属计,相对于汽油计为100ppm以上,所述钡化合物选自磺酸钡, 环烷酸钡,烷基水杨酸钡和一种α-烷基烷烃单羧酸钡。 使用该燃料组合物的火花点火发动机相对于碳与火花塞的粘附性而具有改进的特性。 即使在发动机配备有排气点火控制装置的情况下,来自发动机的排气也不会使排气净化催化剂劣化。
