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

  2. 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?

  3. 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

  4. 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

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

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

  7. Compound semiconductor devices • High efficiency • High temperature operation (>100°C) • Robust • Photon counting • Energy resolution • Fast response

  8. Oil Analysis - 1 E-type Jaguar After 2000 miles

  9. Oil Analysis - 1 500 miles – “flushing oil”

  10. 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 – 0116 252 5519john.lees@le.ac.uk
