oil dilution modeling using a multicomponent model

摘要

Patent specification: "Oil dilution modeling using a multicomponent model". The present invention relates to a method for determining the composition of a fuel in a lubricant that is located in an internal combustion engine compartment. the composition of a fuel having at least a first portion of a first fuel component and a second portion of a second fuel component (k2) is predefined. The mass flow (mff) with which fuel is introduced into the lubricant in an introductory phase or discharged from the lubricant and from the compartment in an unloading phase is determined. The mass flow composition (mff) is determined from a first mass flow (m1e; m1a) of the first fuel component (k1) and a second mass flow (m2e; m2a) of the second fuel component (k2). ), which are determined on the basis of (a) an input parameter (ep) at the input phase or a discharge parameter (ap) at the discharge phase, and b) the first portion of the first fuel component (k1) and the second portion of the second fuel component (k2) in the fuel.
