Abstract (en)
[origin: DE102013202038B3] The air heat characteristics of air heat flow (3) supplied to engine combustion chamber (1) and exhaust gas heat characteristics of delivered exhaust gas heat flow (9) are determined. The heat distribution factors which indicate a fraction of exhaust gas heat flow reduced around air heat flow related to injected fuel heat flow (5) are determined. The engine supplied fuel mass is calculated from one of air and exhaust heat characteristics, and heat distribution factors. The fuel injector is controlled as based on comparison value of supplied fuel mass and fuel mass reference value.
