One factor in estimating the performance potential of a new automobile fuel prior to market introduction is understanding the fuel’s auto ignition propensity, historically qualified by its research octane number (RON), motor octane number (MON) and sensitivity (S = RON – MON). In order to estimate the octane numbers, researchers typically need multiple liters of the new fuel, potentially involving a prohibitive expense for exotic new fuels. This project attempts to predict the octane numbers using small sample volumes, less than 0.5 ml of fuel; this would mean lower costs in screening new fuels, leading to more potential fuels being considered. To predict the octane numbers, we build Gaussian process models.  We implement a greedy computational kernel search to optimize the types of structures our Gaussian process can learn.  Results suggest these approaches are both computationally effective and efficient.
