摘要： An oxygen sensor includes a base body portion; and a plurality of function layers laminated on a surface of the base body portion. The function layers includes a solid electrolyte layer adapted to conduct oxygen ions; a reference electrode layer located on a base body portion side of the solid electrolyte layer; a sensing electrode layer located on the opposite side of the solid electrolyte layer to the reference electrode layer; a heater portion adapted to activate the solid electrolyte layer by heating; and a gas diffusion layer formed between the reference electrode layer and the base body portion, and adapted to diffuse a reference gas within the gas diffusion layer. The gas diffusion layer is formed to have a porosity indicating a limit current value ranging between 60 μA and 200 μA. The limit current value is a value of a current flowing between the reference electrode layer and the sensing electrode layer when the current flowing therebetween becomes substantially constant during the process of bringing a voltage applied therebetween higher.

摘要： A bent front wall 2a of a roof panel 2 is not bent at least inwardly of a press-worked direction of the roof panel 2, so that a front end of the roof panel 2 is free from undercut formation. This eliminates the necessity to further machine the front wall 2a of the press-worked roof panel 2, using for example a cam. Thus, manufacturing cost may be reduced without increasing man-hour.

摘要： In a heated type oxygen sensor having a sensing element responding to changes in the exhaust oxygen content and a heater inside, a diagnostic system for diagnosing deterioration of the heated type oxygen sensor comprises an electronic control unit being responsive to an engine temperature for discriminating whether the engine is in a cold-engine state or in a fully warmed-up state. The diagnostic system includes a first warm-up time setting circuit for setting a predetermined oxygen sensor's warm-up time at a first delay time which is preset to be suitable for the cold-engine state, during cold-engine operations, and a second warm-up time setting circuit for setting the predetermined oxygen sensor's warm-up time at a second delay time which is preprogrammed to be suitable for the fully warmed-up state, during fully warmed-up engine operations. The diagnostic system makes a diagnosis on deterioration of the oxygen sensor under a particular condition in which an elapsed time, measured from a time when the heater is turned on, reaches the predetermined oxygen sensor's warm-up time set depending on during cold-engine operation or during fully warmed up engine operation.
