540i O2 Sensor

Your car’s oxygen sensor is a major part of the emission control system. Basically, its function is to feed the data to the engine management computer so as to help the engine run efficiently and make it produce few emissions. Present cars have at least one computer installed on them. This device is tasked to monitor engine emissions and adjust the engine to keep emissions low.

Generally, there is a particular and perfect ratio of air and gasoline depending on the amount of hydrogen and carbon found in a given amount of fuel. There will be a fuel left over following the combustion in the event that there is a lesser air than the perfect ratio. When this happens, the so called “rich mixture” is present. Rich mixtures do not offer good effects because the unburned fuels produce pollution. On the other hand, if there is more air than the perfect ratio, there will be excess oxygen. This is called the lean mixture. This mixture produces more nitrogen-oxide that can add up the pollution. Another thing is that, it causes poor performance and engine damage in some cases.

BWM understands this problem that’s why its production of innovative and useful vehicle gadgets such as BMW 540i oxygen sensor is very consistent. This component is very important because the amount of oxygen that the engine can pull in depends on many factors such as the air temperature, engine temperature, barometric pressure, load on the engine, and many more.

The oxygen sensor is placed in the exhaust pipe and recognizes rich and lean mixtures. A chemical reaction generating a voltage is involved in its mechanism. The computer looks at the voltage to determine if the mixture is either rich or lean. Then, it adjusts the amount of fuel that enters the engine.
