AbstractOptimized preventative maintenance schedules and in-situ monitoring of vehicle fluid conditions are essential for vehicle reliability, especially when operating in extreme conditions. In the particular case of engine oil, while many types of sensors exist, none directly measure in real time the chemical changes occurring as the oil degrades. A novel, miniature electron spin resonance oil condition sensor that electronically detects free radical concentration in engine oil is proposed. In combination with commercially-available pH, dielectric and humidity sensors adapted for automotive use, a full suite of onboard vehicle fluid diagnostic sensors can be implemented.
