09 - SQR484F EMISSION CONTROL SYSTEM
Oxygen sensor consists of upstream oxygen sensor and downstream oxygen sensor. Upstream oxygen
sensor is installed on the upper part of precatalytic converter assembly, and downstream oxygen sensor is
installed on the lower part of precatalytic converter assembly. The oxygen sensor can detect the oxygen
content in exhaust gas, and determine whether combustible air-fuel mixture is completely burnt out or not, so
as to guarantee the maximum efficiency of catalyst assembly in converting the HC, CO and NOx in exhaust
gas.
