METHOD AND DEVICE FOR EVALUATION OF FRESH AIR MASS IN COMBUSTION CHAMBER, METHOD OF FULL FILLING EVALUATION, RECORDING UNIT FOR THESE METHODS AND VEHICLE EQUIPPED WITH EVALUATION UNIT

摘要

FIELD: transport.;SUBSTANCE: invention relates to transport and can be used for evaluation fresh air mass Ma entering combustion chamber of engine cylinder. According to the invention, during engine cycle the evaluation (128) of total mass Mtot, of gas contained in combustion chamber is performed at the end of fresh air inflow, the evaluation (120, 124) of mass of burnt gases contained in combustion chamber is performed at the end of burnt gas outflow, and the evaluation (128) of fresh air mass Ma is performed from difference between evaluated total mass Mtot and burnt gas mass Mb.;EFFECT: higher accuracy of fresh air mass evaluation which air enters engine cylinder combustion chamber.;13 cl, 3 dwg
