The Research and Motor octane numbers of Liquefied Petroleum Gas (LPG)

This paper presents an experimental study of the Research (RON) and Motor (MON) octane numbers of Liquefied Petroleum Gas (LPG). A comprehensive set of RON and MON data for mixtures of propane, propylene (propene), n-butane and iso-butane are presented, using a method that is consistent with the currently active ASTM Research and Motor test methods for liquid fuels. Empirical models which relate LPG composition to its RON and MON are then...
