  • Method of detecting soot in engine oil using microwaves
    Patent number: 4345202
    Abstract: To measure the percentage of soot in a diesel engine crankcase oil without any significant influence by oil additives or contaminants which build up in the oil during usage. The relative permittivity of the oil is measured in the microwave region of 8-12 GHz (X band). For soot content up to about five percent, the relative permittivity of the oil is a substantially linear function of the soot content.
