“…The composition can be inferred by using MFB models, e.g. Rassweiller and Withrow model [28], assuming complete combustion and using initial known variables, such as the injected fuel ( , ) or the air admitted ( , ). In this manner, the only unknown is the residual gasses, which can be obtained as a function of the total mass.…”

The development of one cycle resolution control strategies and the research at HCCI engines demands an accurate estimation of the trapped mass. In contrast to current methods for determining the mass flow, which are only able to determine averaged values of the flow entering the cylinders, the present paper proposes a methodology based on the in-cylinder pressure resonance. The determination of such frequency allows inferring the cylinder mass with one cycle resolution. In addition, the method permits determining error metrics based on the mass conservation principle. Validation results for a reactivity controlled compression ignition (RCCI) engine equipped with electrohydraulic variable valve timing (VVT) are presented to illustrate the performance of the method.

“…Rassweiler et al [16] introduced an SOC detection method using pressure rise due to combustion, and McCuiston et al [17] and Mittal et al [18] proposed a simplified HR model [9,19,20]. These methods describe the combustion process well; however, it is difficult to apply them to real-time applications due to great data acquisition until the end of combustion as well as high computational load.…”

“…In fact, as far as the imep evaluation is concerned, an erroneous adjustment of the TDC reference position has been recognized to be a major error source: an uncertainty of 1°CA is expected to provide a change of up to 10% in the calculated value of the imep from the pressure-volume indicated diagram [10]. The effects that crank angle phasing errors can have on the heat release rate and mass fraction burnt have not been clearly defined and quantified [11]. Finally, the measurement noise should be removed from the pressure signal by means of a numerical treatment, which is usually applied after the data have been averaged over several consecutive cycles.…”
