DISPOSITION OF PROTECTIVE TUBE AND SEAL OF IMPROVED EXHAUST GAS SENSOR |
摘要 |
An improved oxygen sensor of the type adapted for installation in the exhaust conduit of an internal combustion engine. The improved sensor uses a metal oxide element to sense the partial pressure of oxygen in the exhaust gases to which the sensor is exposed. The sensor has a steel body and a ceramic member which extends into the exhaust gases to permit the exhaust gases to produce variations in an electrical characteristic of one of the sensor components. The improved sensor has a perforated protection tube (18) that has a radially extending flange (78). The flange (78) is located between the steel body (12) and the ceramic member (16), which forms a seal preventing exhaust gases from inside the engine's exhaust conduit from leaking beyond the sensor to the atmosphere. |
