Automated Oil Reblending System

Precise monitoring and maintenance of engine lubricating oils is essential to extend operating life and minimize engine wear. Oil analysis has long been used by the Navy for preventative maintenance of its fleet. However, the manpower requirements for these maintenance programs place a significant burden on personnel. There is demand across all the armed services for the automation of preventative maintenance operations, and a shift to more cost-effective condition-based maintenance (CBM) programs. New technologies to automate engine maintenance are also of great interested for both manned and unmanned vehicles. We propose a feedback-controlled continuous oil blending system that will eliminate the need to ever change the oil in an engine. The system employs our novel miniature electron spin resonance spectrometer, combined with a proprietary feedback system to continuously replenish additives lost during normal engine operation, without operator intervention.
