    摘要： A quaternary ammonium hydroxycarboxylate is produced by quaternizing a tertiary amine with a hydroxycarboxylic ester represented by the following Formula 1: wherein R1 to R3 are as defined in the disclosure. By using only one tertiary amine having at least one substituent different from R1 of the ester moiety of the hydroxycarboxylic ester and by controlling the reaction conditions, a mixture of quaternary ammonium hydroxycarboxylates having different quaternary ammonium ions is produced. By reacting an inorganic acid with the quaternary ammonium hydroxycarboxylate or its mixture, a quaternary ammonium salt of inorganic acid or its mixture is produced.

    摘要： A misfire diagnostic system for an Internal combustion engine comprises a crank-shaft angle sensor for monitoring a crankshaft angular velocity reflecting a combusting condition of each of engine cylinders, and a control unit for calculating an angular-velocity correction factor of each of the engine cylinders on the basis of the angular velocity in every engine operating region only under a stable engine operating condition. The control unit corrects the angular velocity by the angular-velocity correction factor of each of the engine cylinders for every engine operating region. The presence of a misfire is accurately decided on the basis of the angular velocity corrected for every engine cylinder and for every engine operating region.
