    摘要: The cavity of a plasma jet ignition plug is configured in a stepped shape; i.e., composed of a constricted portion and a diameter-increased portion (65). The inner diameter (B) of the constricted portion is made smaller than the inner diameter (A) of the diameter-increased portion. Further, as measured along the direction of the axis O, the length (Y) of the constricted portion is made equal to or greater than the length (X) of the diameter-increased portion. This configuration suppresses a pressure loss produced when the generated plasma expands within the cavity. As a result, the energy of the plasma at the time of jetting is increased, and the igniting performance for an air-fuel mixture can be improved.

    摘要: An initial position determining method is described for a position calculating operation for satellite signals from a positioning satellite. Signals are received from a positioning satellite. A number of candidate ranges are set. An estimated reception frequency for a received signal is calculated. A range may be selected from the candidate ranges based at least in part on a difference between a measured reception frequency and the estimated reception frequency for each range. A representative position from the selected range may be selected as the initial position to be used for a position calculating operation.

    摘要: An ignition device for a plasma jet ignition plug is provided. A resistance for decreasing electric noises is not incorporated in a plasma jet ignition plug. A resistance of not less than 1 KΩ and not more than 20 KΩ is provided to a path from a spark discharge circuit to a center electrode, thus reducing the generation of electric noises at the time of trigger discharge. Along with the reduction of the generation of electric noises, a loss of energy at the time of plasma discharge can be reduced by setting an inner resistance provided to a line extending to the center electrode from a plasma discharge circuit to 1Ω or less. Accordingly, the plasma jet ignition plug can jet flame-shaped plasma sufficiently large for igniting an air-fuel mixture.
