Beschreibung
Zusammenfassung:	A method for estimating a peak cylinder pressure associated with operation of an internal combustion engine may include receiving, in a cylinder combustion model, a fuel signal and an air signal. The cylinder combustion model may be configured to estimate at a first crankshaft angle, a first mass fuel burn rate and a first burned fuel-air ratio associated with combustion. The cylinder combustion model may also be configured to estimate at a second crankshaft angle, a combustion ignition delay associated with the combustion, and estimate at the second crankshaft angle, a start of combustion associated with the combustion of the fuel and the air supplied to the cylinder. The cylinder combustion model may be further configured to estimate, based at least in part on the start of combustion, a peak cylinder pressure associated with the combustion of the fuel and the air supplied to the cylinder.
