Mazda Oxygen Sensors

Environment friendly automobiles are being promoted by most automakers in order to contribute with the conservation of good atmospheric condition. However, that sounds odd, because in reality waste materials from machineries do not give any good contribution to the environment. All that auto manufacturers can do is develop equipments that can minimize the harmful effect of the vehicles’ exhaust and continuously improve the quality of emissions control system as well as their engineering standards. Oxygen sensors are among the most effective devices which the automotive industry has produced concerning its responsibility to take action with the global problem as one of the biggest contributor of air pollution. Internationally marketed automobiles such as Mazda are expected to play valuable part in that objective. Thus utilizing Mazda oxygen sensors is very much necessary.

The presence of oxygen in the process of combustion leads to burning of gasoline, so right amount of oxygen in the system should be monitored. The oxygen sensors’ job is to inform the driver about the amount of oxygen present in the exhaust mixture by sending the data to the vehicle computer. The smell of rotten egg, black smoke from the exhaust, and poor performance mileage are the usual effects of inefficient oxygen sensors. This is caused by a non-balanced ratio of hydrogen and carbon content as against the amount of fuel. There is no particular amount of those elements required in order to achieve perfect ratio. This aspect basically depends on the type of engine. Mazda runs with various kinds of engines, thus they possess different perfect ratios. For a gasoline engine, the perfect ratio of air and gasoline amount runs 14:7:1. When lesser air is present than that of perfect ratio, the exhaust system would fail to burn all the fuel. The mixture produced with the kind of ratio is called rich mixture which results to pollution. And if there’s more air in the combustion, the mixture is considered as lean mixture. In the same way, the result is more pollutant elements or nitrogen oxide, and may actually lead to poor performance or worse create engine damage.

Mazda oxygen sensor is positioned in the exhaust pipe, in the location where the oxygen content can be measured right before it leaves the cylinder. It is also known as O2 sensor, lambda probe, lambda sensor, lambda sond or EGO sensor. This instrument accurately checks the red-hot exhaust hundreds of times per minute with the goal of helping the emissions control system produce the least exhaust gases as possible. The chemical reaction that the sensor produces generates voltage, which then determines if the mixture is lean or rich and adjusts the amount of fuel entering the engine for balancing. If the sensor fails to execute its operation properly, the computer then would end up guessing the air and fuel ratio and consequently also fail to adjust fuel amount. The sensing ability of a Mazda oxygen sensor can be affected by altitude, air and engine temperature, barometric pressure, engine load and some other aspects.
