Abstract
In order to study the wear of cylinder bore fundamentally, a reciprocating friction tester was produced and utilized. The friction between a cast iron and a piston-ring and the wear of the cast iron were examined under the corrosive oil with sulphuric acid.
The findings are summarized as follows; (1) The friction and wear around TDC and BDC was confirmed to be greater than between these reversal points. (2) The friction and wear around the reversal points increased with the sulphuric acid which has caused the deficiency of oil film and the corrosion of the cast iron.
