Vehicle fuel consumption and emission modelling: an in-depth literature review

Validated analytical modeling of diesel engine regulated exhaust CO emission rate

“…The research assumptions in this research include the following assumptions: (1) as to the field data, all vehicles pollute similarly for the same average speed and vehicle-miles traveled; (2) as to the field data, standard deviation in recorded speeds is small so that it can be negligible; (3) the interval variable in the statistical analysis is a random variable that is normally distributed; and (4) the models developed in this study are limited to diesel trucks and light-duty vehicles.…”

“…2,3 Empirical modeling and statistical modeling have been adopted in several research articles in the field of powertrain modeling. 2 For instance, Lindhjem et al 4 presented the physical emission rate estimator (PERE) which has been developed to complement the MOtor Vehicle Emission Simulator (MOVES) greenhouse gas (GHG) emission model for increasing the level of accuracy in estimating on-road vehicle emissions. They proposed the PERE as an empirical model that is partly based on the principles of physics in order to estimate on-road vehicle emissions.…”

“…However, no analytical model has been developed of diesel engine exhaust CO emission rate yet. 2 The following contributions are accomplished in this article: (1) unprecedentedly developing and validating analytically a model of the steady speed diesel CO exhaust emission rate for trucks (sections ''Modeling analytically the steady speed regulated diesel exhaust CO emission rate'' and ''Validating the developed model experimentally'') and (2) proving through statistical analysis the accomplishment of deviation of 1.7% of the simulated results from the corresponding field data outperforming other widely recognized models such as the comprehensive modal emissions model (CMEM) and VT-Micro for all freeway cycles (section ''Statistical analysis of the results of the validation'').…”

“…25 The developed model addresses a moment after opening the exhaust valve in the exhaust system at the average temperature of exhaust. The developed model does not need to incorporate an additional section of ''after-treatment'' for several reasons: (1) the developed model predicts the CO formation rather than CO 2 formation, (2) there is no analytic conversion to convert CO 2 into CO, and (3) there is no catalytic converter to convert CO into CO 2 but through the water-gas shift reaction which is included in the developed model.…”

Design of vehicle cruise control using road inclinations

“…In [6] the approach was evaluated in real experiments where the road slope was estimated by the method in [21]. Paper [3] classifies several modeling approaches for vehicle fuel consumption and emission, such as microscopic, mesoscopic and macroscopic modeling methods. From the aspect of microscopic approach, models of vehicle dynamics are preferred in the paper.…”
