Do you know that the efficiency of your BMW 7 Series depends upon the richness or leanness of the air fuel mixture? Having a precise amount of air and fuel mixture will surely optimize the performance of your car, specifically the ignition and fuel system. The ideal ratio would stay at 14.7:1; however, it is a known fact that vehicles do not operate perfectly, so the ratio of your air fuel mixture would fluctuate at one time or another. To address this particular need, your car has been equipped with a BMW 7 Series oxygen sensor.
Also known as 02 sensor, your BMW 7 Series oxygen sensor is an exhaust system component that serves a primary function of detecting the air-fuel mixture of your internal combustion engine by evaluating the amount of oxygen present in the exhaust gas. It then sends live information to the powertrain control module of your car in order to execute the necessary adjustments. The air fuel mixture will be increased or decreased by the PCM, depending on the information sent by the BMW 7 Series oxygen sensor.
So how does your BMW 7 Series oxygen sensor precisely measure the amount of oxygen in the exhaust gas? Actually, it does its job with the help of a sensing element—a zirconium ceramic bulb coated on both sides with thin layer of platinum. The bulb’s interior is vented through the wiring or the sensor body to the outside temperature. On the other hand, the exterior part of the BMW 7 Series oxygen sensor is exposed to the hot exhaust gases.
Just like the other car components, your BMW 7 Series oxygen sensor will eventually wear out—because nothing lasts forever. The sensing element will sooner or later be contaminated with oil ash and other contaminants from the normal process of combustion. When this happens, it would reduce its ability to quickly respond to the changes in the air fuel mixture.
