The subject of this paper is a unique single-cylinder, direct injection lubricant test engine which matches current and future diesel engine design trends. The paper demonstrates that lubricant test results from this engine correlate with results from a highly turbocharged, six-cylinder engine when operating with both cutback and tight-fitting crown land pistons. An additional finding from this study was a correlation in both engines between ring weight loss and cylinder bore polishing when tight-fitting crown land pistons are used.
