You don't want to breathe an air with a pollution level harmful to your health, not even the air that smells stinky right? There's not much we can do about the progress of air pollution. But through technological improvements and with ordinary people's small ways, rate of its progress can at least be slowed down. By simply making sure that the emissions control system of your Cadillac can provide efficient job, you are already making a very valuable contribution.

One of exhaust system's parts which serve an essential job in producing exhaust with the least level of toxic elements is the oxygen sensor. If your Cadillac houses a good quality Cadillac oxygen sensor, the machine would most likely prevent the occurrence of stinky smell of rotten egg and emergence of black smoke from the exhaust tips. That indicates lesser amount of hydrocarbons, nitrogen oxide, and carbon monoxide in the waste products. It also means prevention of engine damage, good mileage and better performance.

The Cadillac oxygen sensor is a hollow tube which is divided into three compartments by a U-shaped platinum-coated rod. It's a mechanism that responds to the oxygen by producing electrical signal. Significantly, it works on checking the red-hot exhaust hundreds of times per minute in order to get the accurate amount of oxygen content, subsequently determining whether the mixture is lean or rich. These are exhaust mixtures which do not have perfect fuel, air and hydrogen ratio, and can both result to bad exhaust quality if not given the necessary balancing.

After the oxygen sensor obtained the data, it would direct the information to the vehicle computer. A computer would then process necessary adjustments to correct or at least trim down the excess, and reach the level nearest to perfect ratio. Perfect ratio however, depends on the type of engine which the Cadillac is equipped, so as the kind of oxygen sensor used. The computer will also provide a data of the system's operation by converting the output into something understandable by human for monitoring purposes.
