Automotive Electronic Control Units
Automotive oxygen sensors are specialized devices used in vehicle emission control systems to measure the amount of unburnt oxygen present in exhaust gases. They work by comparing the ratio of oxygen to other gases in the exhaust stream to the ideal ratio found in fresh air. This information is then used by the engine management system to adjust fuel injection and ignition timing, ensuring optimal combustion efficiency and minimizing harmful emissions. These sensors are typically located in the exhaust manifold or close to the catalytic converter and operate at high temperatures, requiring careful design and construction to ensure durability and accuracy. Over time, automotive oxygen sensors can become fouled or degraded, leading to decreased performance and increased emissions; regular maintenance and replacement are essential for maintaining optimal vehicle performance and reducing environmental impact.
