The original MAF sensors from Vitesco Technologies precisely measure the air mass in the air intake system of diesel, gasoline, hybrid and fuel cell engines to enable ideal combustion.
 
Furthermore, the precise air mass measurement supports optimized fuel consumption, OBD requirements and, in the case of diesel engines, helps to control the exhaust gas recirculation rate and reduce raw nitrogen oxide emissions. For special applications, the MAF is also used in secondary air systems (e.g. in systems for heating or for free-burning the catalytic converter).
 
The MAF is based on a chip with MEMS technology. Depending on the variant, air mass and air temperature or, optionally, air pressure and humidity can be measured in order to obtain an even more precise signal. The MAF communicates with the engine control unit via an analog or digital signal. It is always installed after the air filter and before the turbocharger in the intake system.
