Land Rover Discovery Air Flow Meter

Bosch Air Flow Meter - 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 load sensor’s accuracy must not be adversely affected by pulsation, return flows, EGR, and camshaft variable timing, or 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. The Bosch micromechanical air-mass meter HFM5 is an optimized component which complies in full with the above stipulations.

FIC Air Flow Meter - FIC rebuilt Air Flow Meters go thru a rigorous cleaning and inspection before they are accepted for remanufacturing. The process; AFM's are stripped to the component level. - All parts, mechanical and electrical are tested to meet OEM specifications. - Unit is assembled using known good parts. - Simulator then runs AFM through all phases of operation. - Spring tension, wiper position and CO screw are calibrated to OEM specification. - Once the AFM meets all OEM specifications the unit is sealed and packaged.
