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.


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).



 Testing Data:

                             Exhaust gas temperature at 350°C

Sensor voltage (MV) at λ=0.93~0.97


Sensor voltage (MV) at λ=1.05~1.10


Response time (600MV~300MV)

         < 250MS

    Heating power at 12V

        12w/18w(for different system)





Fuel:unleaded petrol(quality same as  93# or above)

Operating Temperatures:

Exhaust gas at sensor element: 350°C ~ 850°C

Hexagon of the sensor housing: ≤570°C

Cable and protective sleeve: ≤250°C

Connector:  ≤120°C


1) 10 months from the delivery time.

 (But please use the fuel without lead and no for taxi and other commercial vehicles).

Features: 1) Good Design and outstanding performance meet or exceed the OE  equipment.

2) fast reaction, high performance properties

 FUNCTION: 1) Save up to 15% of fuel expense. 

 2) Meet the strictest exhaust emissiom standards. 3) Avoid the repair expense due to damaged three-way catalytic converter.
