TOYOTA OXYGEN SENSORS

Appearance: DENSO Apply:GEO/TOYOTA oxygen sensors' Description

2 WIRE Oxygen Sensor ( Lambda Sensor) Non-heating oxygen sensor, Be installed near the engine.  Depend on the exhaust gas to

heat the Zirconia tube then the oxygen sensors can start to work.

Construction:

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).

                

            

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

2) fast reaction, high performance properties

Warrant:  

1) 10 months from the delivery time.

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

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

 2) Meet the strictest exhaust emissiom standards 

 3)Avoid the repair expense due to damage three-way catalytic converter
