Auto Oxygen Sensor Regal 12621696 for Buick  

Auto Oxygen Sensor Regal 12621696 for Buick  Production introduction:   The lambda sensor is used to indicate whether the fuel mixture is rich or lean. The levels of oxygen are determined by exposing one electrode to the outside air and another to the exhaust gas. The difference in oxygen content causes a flow of electrons through a ceramic element that generates a voltage potential between two boundary layers. Oxygen sensor is the standard configuration of automobile. It uses ceramic sensitive element to measure the oxygen potential in the exhaust pipe of automobile, and calculates the corresponding oxygen concentration according to the principle of chemical balance, so as to monitor and control the combustion air-fuel ratio, so as to ensure the product quality and exhaust emision up to the standard.
