ABSTRACT:
A system and method to predict engine air amount for an internal combustion engine is described. Included is a method to predict a change in engine air amount based on engine position. This method especially suited to engine starts, where engine air amount is difficult to predict due to low engine speed and limited sensor information. The system and method provides the prediction of engine air amount without extensive models or calibration. Fuel is supplied based on the predicted engine air amount.
