กก In order to comply with the vehicle emission limits demanded by law, it is necessary to maintain a given air/fuel ratio exactly. |
| This requires sensors which precisely register the actual air-mass flow and output a corresponding electrical signal to the open and closed-loop control electronics. |
|
The micromechanical sensor element is located in the plug-in sensor's flow passage. This plug-in sensor is suitable for incorporating in the air filter. There are different sizes of measurement venturi available depending upon the air throughflow. The micromechanical measuring system uses a hybrid circuit, and by evaluating the measuring data is able to detect when return flow takes place during air-flow pulsation. |

|
| The load sensor's accuracy must not be adversely affected by either pulsation, return flows, EGR, and camshaft variable timing, nor by changes in intake air temperature. |
|
|
| In addition to improvements in its function, and a more rugged design, the following air-mass meter features are also of considerable significance: compact construction, low weight, low power consumption, high quality and low costs. Our air-mass meter is an optimised component which complies in full with the above stipulations. |
