Automotive sensors and actuators

Sensors in the cars exhaust systems are needed to regulate the amount of emissions release into the air. Automotive exhaust emissions are a growing concern because we all breathe the same air. Reducing exhaust system emissions is a main concern in the effort to eliminate air pollution.

Automotive sensors and actuators, such as the oxygen sensor has become one of the world's most important technological advancements by reducing exhaust emissions by cars. These oxygen sensors are now a standard feature when creating performance and racing parts for professional championships, and also for the cars built for the general public. Most cars have one or two oxygen sensors. Since the introduction of Onboard Diagnostics II, the number of oxygen sensors per vehicle has doubled, the extra sensors are used future down in the exhaust line from the catalytic converter to observe its operating efficiency.

Even though the oxygen sensors perform such an important task, few people are even aware of their presence, let alone the major role oxygen sensors play in engine performance and reducing pollution.
