TL;DR: In this paper, a two-zone model was used to determine information about the burned and unburned gas temperatures and the modification of the standard Rassweiler and Withrow expression to incorporate polytropic indices for compression and expansion.
Abstract: This paper investigates a number of new approaches to mass fraction burned analysis for application to spark ignition engine combustion processes. The rationale for these new approaches is to retain the simplicity and computational efficiency of the technique of Rassweiler and Withrow, but to overcome some of the limitations inherent in the standard methods. The approaches investigated include the use of a two-zone model to determine information about the burned and unburned gas temperatures and the modification of the standard Rassweiler and Withrow expression to incorporate polytropic indices for compression and expansion.The investigation makes use of an engine simulation model, which was used to generate the pressure data. This technique provided a ‘known’ burn rate against which to evaluate the methods investigated. Some experimental data taken from a Rover K4 optical access engine is also presented.The successful aspects of this investigation are the use of the Rassweiler and Withrow equatio...

TL;DR: In this paper, a single cylinder, spark ignition engine is operated both with gasoline and raw biogas at a compression ratio of 10 under wide open and part throttle conditions, and the engine performance, combustion and emission parameters are measured over a range of speed variations.
