Abstract

Soot caused oil thickening is a known failure mode for lubricants operating in heavy-duty diesel engines. An integrated chemical sensor has been developed. It consists of a bulk acoustic wave quartz resonator and a capacitor formed between a grounded electrode of the quartz resonator and an additional electrode. Two series of engine oil drain samples were tested and the temperature effect on soot agglomeration was investigated. Different methods for diagnosing the real time oil condition and predicting the oil´s residual useful life are proposed.
