Is real time engine oil analysis possible? John E. Lees Space Research Centre, University of Leicester How to successfully adopt new technologies Wednesday 12 January 2011

Space Research Centre Real Time Oil Analysis  Is it important?  Does anyone really want it?  Is it possible with current technology?  Is the cost too high?  Are the devices too bulky?  Is there a viable solution?

Space Research Centre Formula 1  No real time oil analysis  Track side analysis  Over 500 sensors on each car  Oil from car tested using X-ray fluorescence spectroscopy  “That’s the holy grail” Mike Copton, 2004

Space Research Centre Economics  Change the lubricant too early and you will waste money: Replacing oil prematurely Taking vehicles off the road too often  Change the oil too late and you will waste money: Higher fuel bills Risk higher maintenance costs

Space Research Centre Economics  Estimated direct and consequential annual loss to industries in the USA due to wear is approximately 1-2% of GDP. (Heinz, 1987)

Space Research Centre Silicon detectors  Silicon X-ray Detectors  Good spectral response  Operate cooled < -20°C Comparison of X-ray fluorescence spectra of old (solid line) and new (circles) motor oil.

Space Research Centre Compound semiconductor devices High efficiency High temperature operation (>100°C) Robust Photon counting Energy resolution Fast response

Space Research Centre Summary  Real-time oil analysis would provide monitoring of key contaminants  In-situ robust device operating reliably at high temperatures  Accurate measurement would ensure optimum oil change  Economic and environmental benefit  Contact: Dr. John Lees –
