Oxygen Sensor 11787548961 For BMW R58 R59 R60

There are some differences between the rear oxygen sensor and the front oxygen sensor in design, mainly in their position, function and working principle:

1. Location: The front oxygen sensor is usually installed at the upstream position of the engine exhaust manifold to monitor the oxygen content in the combustion chamber to help the engine control system adjust the fuel mixture ratio. Then the oxygen sensor is usually installed at the downstream position of the exhaust pipe to monitor the oxygen content in the exhaust gas to help monitor and control the vehicle's emissions.

2. Function: The front oxygen sensor is mainly used to monitor and adjust the oxygen content in the engine combustion chamber to ensure combustion efficiency and fuel economy. The post-oxygen sensor is mainly used to monitor the oxygen content in the exhaust gas to ensure that the vehicle emissions meet the environmental protection standards.

3. Working principle: The front oxygen sensor measures the oxygen content in the combustion chamber, converts it into an electrical signal and feeds it back to the engine control system, thus adjusting the fuel mixture ratio. By monitoring the oxygen content in the exhaust gas, the post-oxygen sensor helps the vehicle's exhaust system to adjust its working state to ensure that the exhaust gas meets the regulatory requirements.

Generally speaking, the design difference between the front oxygen sensor and the rear oxygen sensor is mainly reflected in its installation position, function and working principle. Both of them play an important role in vehicle performance and environmental protection emissions, and need to be selected and maintained according to the specific conditions and needs of vehicles.
