Investigation of temperature dependent viscosity change of a standard engine oil diluted with alternative fuels

Predictive maintenance can be used heavily in aviation, defence industry and heavy industrial engines. How and to what degree the usage of alternative and renewable fuels effect the engine oil must be researched. In this paper engine oil used in heavy diesel engines will be diluted with diesel, biodiesel and 1-Dodecene (jet fuel substitude) fuels (1-2-5-7-10% in weight), physico-chemical (parameters from the standart values will be considered for predictive maintenance. In conclusion; the effect of standart (eurodiesel), alternative (biodiesel) and military and aviation fuels on the chemical properties of the engine oil for every engine that uses these fuels will be revealed. In this data we can see at which point the oil becomes inadequate for use because of low performance, the condition of the fuel and ignition systems. This data will be the ground work for the development of predictive maintenance algorithms and machine learning. Keywords: predictive maintenance, engine, engine oil, dilution, characterization
