Auto Oxygen Sensor Epica 9042907 for Chevrolet

Auto Oxygen Sensor Epica 9042907 for Chevrolet Production introduction:   many modern oxygen sensors do not need outside air as a reference. Rather, a reference pump current is applied to the Nernst cell, which simulates the influence of the air. In these sensors, a gap in the element for the reference air is not required. Therefore, the sensor element requires less volume and heating it up requires less time and energy. Furthermore, operating without reference air makes the sensor less sensitive to contamination. 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.
