Where is the car oxygen sensor?

Oxygen sensors are installed behind the exhaust manifold, one in front and one in the back.

Automobile oxygen sensor is a key sensing element in the control system of EFI engine, and it is also a key element to control automobile exhaust emission, reduce automobile environmental pollution and improve the fuel combustion quality of automobile engine.

Oxygen sensor is a measuring element that uses ceramic sensitive elements to measure the oxygen potential in various heating furnaces or exhaust pipes, and calculates the corresponding oxygen concentration according to the principle of chemical balance, so as to monitor and control the combustion air-fuel ratio in the furnace and ensure the product quality and exhaust gas emission to meet the standards. Widely used in the atmosphere control of coal-fired, oil-fired and gas-fired furnaces.

Oxygen sensor is used in the feedback control system of electronically controlled fuel injection device, which is used to detect the concentration of oxygen and air-fuel ratio in exhaust gas, monitor the combustion of theoretical air-fuel ratio (14.7: 1) in the engine, and send feedback signals to the computer.
