摘要： There are provided a spark plug in which a plating film applied to a ground electrode can be relatively easily removed, without cost increase, to prevent deterioration in ignition performance, and a process for producing the spark plug. A spark plug 1 has a metal shell 3, a ground electrode 27 made of a Ni alloy and a Ni plating layer 28 containing Ni as a main component and applied to surfaces of at least a rear end portion of the ground electrode 27 and of the metal shell 3. A Ni plating film 41 applied to a center-electrode-side part of a portion of the ground electrode 27 to be bent has been irradiated with a laser beam or the like, thereby forming a molten layer 29 in which metal materials of the Ni plating film 41 and the ground electrode 27 are molten together on the center-electrode-side part of the portion of the ground electrode 27 to be bent. The Ni plating layer 28 is formed on a part of the ground electrode 27 other than the part irradiated with the laser beam.

摘要： A plasma jet spark plug and a manufacturing method therefor are disclosed. In a state in which a noble-metal chip having a flange-like outwardly projecting portion is disposed in a communication section of a ground electrode, an electrode base metal of the ground electrode is disposed in a stepped engagement portion of a metallic shell, which retains an insulator therein. While being pressed against a front end portion of the insulator, the noble-metal chip is joined to the electrode base metal, whereby a clearance between the ground electrode (electrode base metal) and the front end portion of the insulator can be closed. Therefore, energy of plasma generated within the cavity does not leak.

摘要： An ECU estimates the temperatures of the heat generating portions provided in a drive force transmission system, or a transaxle, a rear differential, and a torque coupling, in correspondence with not only the rotational speed (the differential rotational speed) of each heat generating portion and the torque transmission rate of the torque coupling but also the outside temperature detected by an outside temperature sensor. If the estimated temperature of any of the heat generating portions exceeds a respective predetermined temperature, the ECU controls operation of the torque coupling to suppress overheating of the heat generating portion. That is, the temperature of each heat generating portion is accurately detected through a simplified structure and overheating of the heat generating portion is effectively suppressed.
