Abstract
A method for sensing the temperature of the air supplied to the combustion chambers of an internal combustion engine for the purpose of detecting air mass. Air temperature can be measured using an inexpensive detector having a transfer function exhibiting a delayed response. Dynamic performance is improved by applying to the detected temperature a temperature correction value that is obtained by applying a transfer function that is substantially the inverse of the transfer function of the temperature detector.
