WebHRR. The best method of validating the HRR model of an ICE is to compare a measurable parameter that the HRR is depended on (such as the fuel consumption) to model prediction. The measured fuel mass was neither used in the modelling of the HRR nor when the fuel consumption was estimated from the modelled HRR/CHR data. For this reason, the … Web1.
