MODELING OIL DILUTION USING A MULTICOMPONENT MODEL

摘要

The present invention relates to a method for determining the composition of fuel in a lubricant located in the housing of an internal combustion engine. The composition of the fuel having at least a first portion of the first fuel component and a second portion of the second fuel component K2 is predefined. The mass flow rate (MFF) at which fuel is introduced into the lubricant at the introduction stage or released from the lubricant and from the housing at the discharge stage is determined. The composition of the mass flow rate (MFF) comprises a) the introduction parameter (EP) of the introduction stage or the emission parameter (AP) of the discharge stage, and b) the first and second fuel components of the first fuel component (K1) in the fuel ( It is determined from the first mass flow rate (m1E; m1A) of the first fuel component (K1) and the second mass flow rate (m2E; m2A) of the second fuel component (K2), which is determined based on the second part of K2).
