PROCEDE D'ESTIMATION DE LA MASSE D'AIR ADMISE DANS UNE CHAMBRE DE COMBUSTION D'UN MOTEUR, ET VEHICULE DE MISE EN OEUVRE |
摘要 |
<p>The method consists of modeling the admitted air mass (M) as a function of a pressure variation (DELTAP) in the combustion chamber from the polytropic gas compression law, P.Vn = c. It comprises a pressure measurement stage within the combustion chamber (2) at a first time in a combustion cycle, a second pressure measurement stage at a second time and a calculation stage of the pressure variation between the two times. The admitted air mass is then calculated according to the formula M = A.DELTAP + B where A and B are variables determined according to the engine speed. An Independent claim is included for a vehicle comprising an I.C. engine.</p> |
