4) Installation notes
Oxygen sensor should be installed in the exhaust gas mixing place, and when a vehicle moves, air cooling metal shell and wire
should be flow.
On the exhaust pipe can ensure the representative of the exhaust components and can meet the requirements of the temperature limit
position. Installation location should be as close as possible to the engine. The exhaust pipe should be provided with screw, screw in
oxygen sensor used for.
nstall the attitude of oxygen sensor
Oxygen sensor should be installed with the horizontal plane angle is greater than or equal to 45 degrees, and the sensor tip down, to
avoid the cold start of condensed water accumulated between the sensor housing and sensing ceramic tube.
Oxygen sensor wire can not bend more than 60 degrees, the bend arc radius is greater than or equal to 20 mm, and the wire should
not bear the tensile stress. The following diagram.
