Use of high-intensity ultrasound as a potential test method for diesel fuel stability

Gareth J. Price, Matthew McCollom

Research output: Contribution to journalArticle


An automotive diesel fuel was subjected to irradiation with high-intensity ultrasound. In addition to the cracking of saturated alkane components of the fuel, sonication promoted polymerization reactions which concentrated aromatic and nitrogen-containing compounds into insoluble sediments having properties similar to those obtained in long-term storage tests on other diesel fuels. Hence the application of ultrasound may prove to be a useful method for accelerated testing and prediction of long-term diesel stability.
