Abstract
A system and method are provided for estimating the flow rate of air entering an air inlet of a turbocharger compressor. A first pressure value corresponds to pressure at or near the air inlet of the compressor, and a second pressure value corresponds to pressure at or near the air outlet of the compressor. A temperature value corresponds to a temperature at or near the air inlet of the compressor, and a speed value corresponds to an operating speed of the turbocharger. The flow rate of air entering the air inlet of the turbocharger compressor is illustratively estimated as a function of the first pressure value, the second pressure value, the temperature value and the speed value.
