5.8. Measuring instrument of a consumption of air (MAF)

The measuring instrument of a consumption of air provides the most direct method to measure engine loading as it measures amount of the air arriving in the engine. The stream of air arrives in the engine through a measuring instrument with warm and cold the film elements forming a part of the bridge scheme. The current passing through a warm film element, maintains its constant temperature at constant level, which above, than temperature of air arriving in the engine. The mass of air is determined by a current necessary for maintenance of temperature of a film element. The more the stream of air and, naturally, its cooling, the is more than a size of a signal submitted on the ESM block.
