Clogged Oxygen Sensors?

TIP…Make certain that your oxygen sensor is working like new….this leads to maximum power and fuel efficiency.

Use of CATACLEAN as recommended, will help prevent carbon deposit build up on your oxygen sensors. As a result, proper air flow will be maintained which translates into maximum performance, fuel economy and reduced emissions.

A petrol engine burns petrol in the presence of oxygen. There is a particular ratio of air and petrol that is optimum and that ratio is 14.7:1 (different fuels have different optimum ratios -- the ratio depends on the amount of hydrogen and carbon found in a given amount of fuel). If there is less air than the optimum ratio, then there will be fuel left over after combustion. This is called a rich mixture. Rich mixtures are bad because the unburned fuel creates pollution. If there is more air than this optimum ratio, then there is excess oxygen. This is called a lean mixture. A lean mixture tends to produce more nitrogen-oxide pollutants, and, in some cases, it can cause poor performance and even engine damage.

The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The mechanism in most sensors involves a chemical reaction that generates a voltage. The engine's computer looks at the voltage to determine if the mixture is rich or lean, and adjusts the amount of fuel entering the engine accordingly.

The reason why the engine needs the oxygen sensor is because the amount of oxygen that the engine can pull in depends on many variables, such as the altitude, the temperature of the air, the temperature of the engine, the barometric pressure, the load on the engine, etc.

When the oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing. Result…..poor performance and reduced fuel efficiency.
