Oxygen sensor is the use of ceramic sensitive elements to measure the oxygen potential in various heating furnaces or exhaust pipes, calculate the corresponding oxygen concentration by the principle of chemical balance, to monitor and control the combustion air-fuel ratio in the furnace, to ensure product quality and exhaust emission standards of measuring elements, widely used in all kinds of coal combustion, oil combustion, gas combustion and other furnace atmosphere control.
The function of the sensor is to determine whether there is excess oxygen in the exhaust gas of the engine after combustion, that is, the oxygen content, and convert the oxygen content into a voltage signal to transmit to the engine computer, so that the engine can achieve a closed-loop control with excessive air factor as the goal; Ensure that the three-way catalytic converter has the maximum conversion efficiency for the three pollutants in the exhaust hydrocarbon (HC), carbon monoxide (CO) and nitrogen oxide (NOX), and maximize the conversion and purification of emission pollutants.
