Exhaust Gas Recirculation

The EGR valve has been around since tail-pipe emissions were a concern in cars. Electronically controlling this valve provides the engine control designer with that much more control over the air-fuel stoichiometry making this world a cleaner place to live. ST’s PRODUCTS are used in this application to improve fuel economy and lower vehicle exhaust gas emissions. Providing solutions from the embedded MICROCONTROLLER to the power SWITCHES, from VOLTAGE regulation to the serial communications physical layer, ST has the answer for your EGR control needs.
