Electronic lambda sensor Oxygen sensor for Volvo Upstream oxygen sensor O2 sensor OE 30756122 ламбда-датчик

Product Description:

Upstream Oxygen sensor
OE NO.:   30757555 30756122

Applicable vehicle type: For Volvo

The automotive oxygen sensor is a sensing component installed on the engine exhaust pipe, used to detect the oxygen concentration in the exhaust gas. It monitors the air-fuel ratio within the engine and transmits feedback signals to the car's computer, thereby enabling precise control of fuel injection volume, reducing fuel consumption and exhaust pollutant emissions, and improving engine performance.

Main Classification

• By Material: They can be classified into Zirconium Dioxide (ZrO₂) oxygen sensors and Titanium Dioxide (TiO₂) oxygen sensors. These two types of oxygen sensors are the most widely used in the current market.
• By Signal Characteristics: They can be classified into wide-range oxygen sensors and narrow-range oxygen sensors. Wide-range oxygen sensors can accurately measure a wider range of air-fuel ratios, while narrow-range oxygen sensors can only determine whether the air-fuel ratio is rich or lean.
• By Heating: They can be classified into heated oxygen sensors and non-heated oxygen sensors. Most modern passenger cars use heated oxygen sensors to enable them to quickly reach operating temperature.
