Due to the application of the universal connector, a few types of the universal types of the universal oxygen sensors substitute a large number of original part sensors. Make a
breakpoint at a proper place on the lead-out sensor and install a universal connector to
connect the sensor with the relate wires of the vehicle.
4 Wire Universal oxygen sensorConstruction:
Zirconia tube- the core element of the sensors.
We can manufacture zirconium tubes independently, and adjust the parameters to the best state meeting to the technology requirements. At present, our products have been under durability test for almost 50,000km at least.
Operational principle:
WHAT’ S “λ”?
Lambda is a mathematical calculation representing air/fuel ratio. The
figure is derived by dividing the actual air/fuel ratio of the engine by
the theoretically correct value [14.7:1].
Stoichiometric Air Fuel Ratio(AFR)=14.7:1 (λ=1)
Mixture rich:the actual AFR is smaller than the Stoichiometric AFR
Mixture lean:the actual AFR is bigger than the Stoichiometric AFR
If the mixed air is too rich (λ<1), the voltage is about 1v, fuel injection need to be decreased;
If the mixed air is too lean, the voltage ia about 0V, the fuel injection need to be increased (λ<1).
