The limitation of fuel entry into the oil sump of an internal combustion engine during operation is important to preserve the tribological properties of the lubricant and limit component wear. For observationand quantification of the effects leading to fuel entry, a highly sensitive and versatile measurement system is essential. While oil sampling from the sump followed by laboratory analysis is a common procedure, there is no system for automatic sampling of all the positions and fast online analysis of the samples.

The aim of the research cluster “Fuel in Oil” is the investigation and quantification of the interaction between the fuel and the lubrication oil caused by late post injections, which are applied for the regenerationof the particulate filter or the NOx storage catalyst. To achieve the objectives, different phenomena like the fuel entry into the lubrication film, the fuel-oil transport by means of the piston rings, the evaporation of fuel out of the oil pan and the impact of the oil separator of the oil dilution were…
