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.
