    摘要: A zincate type zinc alloy electroplating bath which comprises a Zn compound, an alkali hydroxide, a salt of Fe(II, III) or Ni(II), a chelating agent for dissolving said salt of Fe(II, III) or Ni(II) and brightening agents. The chelating agent is selected from the group consisting of a commercially available chelating agent and a reaction product of a mixture of one or more kinds of aliphatic amine with epihalohydrin. The brightening agents contain alkylated polyalkylene polyamine in which some of the basic nitrogen atoms of polyalkylene polyamine are alkylated by alkyl groups of C.sub.1 to C.sub.3, and one or more compounds selected from the group consisting of reaction products of imidazole or its derivative with epihalohydrin and reaction products of imidazole or its derivative with epihalohydrin in the presence of aliphatic amine.

    摘要: In an internal-combustion engine disposed in a vehicle, when the engine is in an idle state and the vehicle speed is not equal to zero and is less than a predetermined value, the air-fuel ratio of the engine is controlled so that the air-fuel mixture is on the lean side of the stoichiometric air-fuel ratio. In addition, even after the vehicle speed becomes zero, the air-fuel ratio is controlled so that the air-fuel mixture is on the lean side for a predetermined time period.
