Oxygen Sensor
•Working principle of oxygen sensor
Oxygen sensor can be used to detect the oxygen content in the waste gas of engine exhaust pipe for internal fuel closed
loop control of ECU, thus maintaining engine combustion at the most reasonable state of air and fuel ratio.
•Appearance of oxygen sensor
•Technical parameters
 Partially thick limit of air-fuel ratio: ＞750 Mvdc
 Partially thin limit of air-fuel ratio: ＜120 Mvdc
 Power of oxygen sensor heater: 7.0W
(The above parameters are measured at engine bench, the working conditions: exhaust gas temperature: 450°C; duty
cycle: 70%; 10Hz; voltage: 13.5V).
 The resistance of heater is: 9.6±1.5Ω (measured at 21°C)
 Operating temperature range: 260-850°C
•Installation requirements
 Installation angle (angle with the horizontal plane): ≥10 degrees
