Authors Abstract
Content
A new mass air flow meter, using a sensor element based on micro silicon technology, is presented. The sensor is able to detect the amount and direction of air flow. It is located in an aerodynamic bypass, which acts as a nonlinear filter. This enables the mass air flow meter to correctly determine the air mass aspirated by a four cylinder engine, even in the case where, due to strong oscillations of the flow, timewise backflow occurs near the measuring position. Results of laboratory and engine tests will be presented.
