|Type:Oxygen Sensor||Car Make:FOR BMW||OE NO.:0258003810||Place of Origin:Zhejiang China (Mainland)|
|Brand Name:PBK||Model Number:0258003810||certificated:ISO9001|
Unheated 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.
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
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).
1) Good Design and outstanding performance meet or exceed the OE equipment.
2) fast reaction, high performance properties
1) 10 months from the delivery time.
(But please use the fuel without lead and no for taxi and other commercial vehicles).
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
