Sažetak
From indicated pressure in engine cylinder the real heat release rate (HRR) can be derived. Such HRR itself is substantial source of in-cylinder combustion process data. These data are useful for numerical simulations of similar in-cylinder processes. Instead of single Vibe function much better representation of the same process is achieved with the sum of multiple Vibe functions with various starts, durations and Vibe exponents. The paper presents genetic algorithm method approach to find these multiple Vibe functions. From such derived Vibe functions a lot of additional informations of combustion process is achieved, for example multiple fuel injections with smeared combustion effects, which are not detectable in HRR.
