Abstract
In a method for predicting and/or correlating additive chemical structure to engine performance, at least one molecular descriptor for one or more additives are used to characterize the chemical structure. Based on the selected molecular descriptors, a value or functional relation of model parameters of a mechanistic engine model for the engine performance e.g. using reaction kinetics parameters is determined. For example, a functional relation between the molecular descriptors and the kinetic parameters by testing compositions comprising one or more additives is determined. Based on the mechanistic engine model a QSPR library describing the relation between the molecular descriptors of the additives and the kinetic parameters an engine performance of other additives may be estimated.
