Product Description
The main purpose of installing front and rear oxygen sensors in automobiles is to monitor and control the oxygen content during engine combustion, so as to ensure combustion efficiency, reduce exhaust emissions, improve fuel economy and protect the environment. The specific reasons are as follows:
1. Combustion efficiency control: The front oxygen sensor is located at the upstream position of the engine exhaust manifold, which is used to monitor the oxygen content in the combustion chamber and feed it back to the engine control system to help adjust the fuel mixture ratio, thus improving the combustion efficiency and reducing fuel consumption.
2. Emission control: The post-oxygen sensor is located at the downstream position of the exhaust pipe, which is used to monitor the oxygen content in the exhaust gas and feed it back to the exhaust system of the vehicle to help adjust the working state of the emission control device, so as to reduce the emission of harmful gases and meet the environmental protection standards.
3. Fuel economy: Through the monitoring and control of the front oxygen sensor and the rear oxygen sensor, the engine combustion efficiency can be ensured to be the best and the fuel mixing ratio is appropriate, thus improving fuel economy and reducing fuel consumption.
4. Environmental protection: Through the monitoring and control of the front and rear oxygen sensors, the harmful gas content in the exhaust gas can be effectively reduced, the environmental pollution can be reduced, and the atmospheric environment and human health can be protected.
Generally speaking, the purpose of installing front and rear oxygen sensors in automobiles is to monitor and control the oxygen content during engine combustion, so as to improve combustion efficiency, reduce exhaust emissions, improve fuel economy and protect the environment. These sensors play an important role in the vehicle emission control system, which helps to ensure that the vehicle performance and environmental protection emissions meet the standards.
