Web23 de out. de 2024 · In a V8 engine, Active Fuel Management (AFM) lifters are used to switch the engine from 8 cylinder operation to 4 cylinder operation to save fuel under light load conditions. WebHow AFM Works. An AFM cantilever with a protruding ultra-sharp tip is raster scanned over the sample, which makes either intermittent or constant contact with the surface. The tip interacts with the sample, experiencing repulsive or attractive inter-atomic forces. A laser beam is reflected off the back of the cantilever onto a detector.
