“…Computer simulations can be used for determining the impact of octane rating, additives, and biocomponent in gasoline on the course of the engine power, its combustion and knocking [50][51][52]. Via computer modelling, there can be also a simulation of the amount of emissions produced [53,54]. Despite all the possibilities of computer modelling, experimental measurements are still irreplaceable, as for their ability to verify the accuracy of computer modelling measurement results.…”
