“…The heat transfer coefficient has to be modeled, with the model attempting to reproduce the heat release rate obtained from experiments. The effects of different heat transfer coefficient models are studied in this paper, where the models used are the Woschni correlation (Bengtsson, Gafvert, & Strandh, 2004;Woschni, 1967), modified Woschni correlation for HCCI engines (Chang et al, 2004), and Hohenberg correlation (Hohenberg, 1979;Sanli et al, 2008;Zeng & Assanis, 1989).…”

Homogeneous charge compression ignition (HCCI) engine technology is relatively new and has not matured sufficiently to be commercialized compared with conventional engines. It can use spark and compression ignition engine configurations, capitalizing on the advantages of both: high engine efficiency with low emissions levels. However, the combustion behavior in an HCCI engine is difficult to predict because it has no spark plug or injector. The chemical kinetics mechanism influences the combustion with some heat losses to the cylinder wall. The effect of different heat loss models in a diesel HCCI engine has to be investigated further. A single-zone thermodynamics model was used in this study along with three different heat loss models: Woschni, modified Woschni, and Hohenberg correlations. It was found that the difference in heat loss models leads to a big difference in the heat flux, and the modified Woschni model has the highest heat flux among these models. The effects of the different scaling factor and characteristic velocity were also investigated. The study concluded that the modified Woschni model produced more accurate results, while the Woschni and Hohenberg models require more tuning of constants before they can be used in a diesel HCCI engine.

“…These models were used to predict combustion phasing [22][23][24][25], load [26], exhaust gas temperature [27], cyclic variability [28] and heat release [29] in HCCI engines. A second model group includes detailed thermo-kinetic models that were used to predict auto-ignition delay [30][31][32][33][34][35], combustion phasing [36,37], HC and CO emissions [38] and heat release [39,40]. The first group requires substantial experimental data, while the second group requires computational resources which are not available for real-time engine control.…”

Abstract-The homogenous charge compression ignition (HCCI) engine is an attractive technology because of its high efficiency and low emissions. However, HCCI lacks a direct combustion trigger making control of combustion timing challenging, especially during transients. To aid in HCCI engine control we present a simple model of the HCCI combustion process valid over a range of intake pressures, intake temperatures, equivalence ratios, and engine speeds. The model provides an estimate of the combustion timing on a cycleby-cycle basis. An ignition threshold, which is a function of the in-cylinder motored temperature and pressure is used to predict start of combustion. This model allows the synthesis of nonlinear control laws, which can be utilized for control of an HCCI engine during transients.
