Automobiles release far fewer pollutants into the
atmosphere than they did 20 years ago, thanks to
sophisticated emission control systems. There are two
critical elements to these systems which, over time,
commonly need replacement.
This device converts dangerous polluting gases (such as
carbon monoxide) into water vapor and less harmful gases.
When a replacement converter is needed, it is often
smaller than the original, factory-installed equipment,
thanks to continually improving technology which lets
converters work more efficiently.
This device constantly monitors the percentage of oxygen
present in exhaust gases and transmits that information to
the engine control computer. The computer then adjusts the
air/fuel mixture to assure the cleanest combustion. A
properly functioning oxygen sensor is therefore critical
to engine performance.
