摘要： An oxygen sensor includes a generally cylindrical casing. A detecting section is disposed at an axially one end side of the casing so as to detect a concentration of oxygen. Lead wires are electrically connected with the detecting section and outwardly extend through an axially other end side of the casing. A seal member is disposed inside an end section located at the axially other end side of the casing. The lead wires pierce the seal member. An insertion section is located at the axially one end side of the casing so that the detecting section projects over the insertion section. The insertion section is inserted into a through-hole formed in a wall of an exhaust pipe, so as to install the oxygen sensor to the exhaust pipe in a condition where the detecting section projects into the exhaust pipe. A ratio of a length of an outer projecting section of the oxygen sensor to a cross-sectional area of the insertion section inserted into the through-hole is set at a value not lower than a value at which a temperature in the seal member reaches a heat resistant temperature limit of the seal member.

摘要： An A/F ratio detecting arrangement includes a sensor casing having an oxygen sensor part arranged between first and second electrodes and an oxygen pump part arranged between third and fourth electrodes, which are heated by a heater. A signal output processing circuit serves to provide an A/F ratio signal. A signal switcher serves to provide a provisional oxygen content signal derived from the first and second electrodes when the oxygen pump part is not activated yet, and the A/F ratio signal when the oxygen pump part is activated.
