On-line measurement of oil dilution is of interest in light of new environmental regulations imposed on today's high-performance engines.  In particular, after-treatment devices such as diesel particle filters (D.P.F.) or deNOx systems need to be periodically re-generated. Such re-generation process is typically performed by using post-injection cycles that can induce a transfer of fuel to the lubricant, resulting in oil dilution by fuel (or "fuel dilution").  

Our patented methodology is based on lubricant labelling using a radiotracer compound.  Fuel dilution & evaporation measurement is performed by circulating engine oil in a measuring chamber where volumic activity of the oil is monitored continuously.  

D-Lube: Fuel dilution monitoring equipment

Benefits:

o     Dilution / evaporation results are supplied on-line, during operation of the engine 

o        Excellent sensitivity and resolution that corresponds to 0.05%/h in terms of of dilution rate;

o        100% discrimination between fuel and lubricant, which is the weakness of the GC method where superposition of the heavy fuel fraction and the light oil fraction induces uncertainties.
