Experimental Analysis of Cylinder-bore Corrosive Wear by Utilizing a Radioisotope Tracer (First Report)

In order to clarify the influence of fuels containing sulfur and ethanol on cylinder-bore wear, the wear measurements by utilizing a radioisotope technique were performed. The results showed that when fuels containing sulfur were used, bore wear rate increased at a specific water temperature and depended on the base number of the engine oil. For this reason, it is estimated that the corrosive wear is caused by sulfuric acid generated from sulfur in fuels.
