All automobiles with standard internal-combustion engines in the United States, Europe, and Japan are now required by law to have oxygen sensors. Mounted in the exhaust manifold, an oxygen sensor continually monitors the oxygen content of the combustion gases that leave a car's engine.
This residual oxygen content Indicates how efficiently the fuel is burning and the engine is running.
The oxygen sensor not only detects the oxygen content the hot gases leaving the engine but also sends an electrical signal to the electronic engine-control system. If the signal indicates that the engine is not operating at peak efficiency, the electronic engine-control system then read justs the amount of air that's mixed in with the fuel, so that the engine again works under optimum conditions.
Fortunately, the conditions that produce minimum pollution also result in peak gas mileage.
The oxygen sensor gives, an average, about four extra miles per gallon of gasoline, probably enough for five to ten trips to the grocery store on each tank of gas.
