ABSTRACT:
An improved exhaust gas oxygen sensor of the type adapted for installation in an exhaust conduit of an internal combustion engine. The improved sensor is of the type employing a titania oxygen sensing element responsive to the partial pressure of oxygen in the exhaust gas. A ceramic insulator supports the titania oxygen sensing element and is of improved design. Prior designs have contributed to cold-working of the electrode lead wires connected to the titania oxygen sensing element. The improved insulator design has a pedestal located adjacent the passages in the insulator through which the lead wires pass for the purpose of minimizing cold-working of the lead wires. This aids in preventing fracture of the wires during their use in a feedback fuel control system employing the oxygen sensor.
