http://mywikimotors.com/m50b25/ WebDec 23, 2024 · MFB50 and Pmax are used for the definition of the injection start angle (SOC): the SOC of the injectors is used as a control lever to individually reach the target value of MFB50. Pmax, instead, is used to set a lower bound for MFB50, preventing the use of SOC settings that would lead to exceeding the maximum tolerable pressure peak.

WebJun 25, 2024 · The combustion phasing was retarded to a MFB50 of 20° CA aTDC to limit peak firing pressures, and the mixture was enriched to limit exhaust gas temperatures. The engine, however, was not knocking at this condition, so there is margin to further optimize the calibration. Of particular note was the fast combustion, with bulk burn durations (10 ... WebMay 24, 2024 · The combustion control system calculates the angular position where 50 % of the injected fuel mass is burned (MFB50) using in-cylinder pressure for every cycle. In addition, the fuel injection timing is changed to make current MFB50 follow the target values. The EGR rate can be estimated by using trapped air mass and in-cylinder pressure when ...
