Abstract
Field-censored failure data collected from six identical Colt-Pielstick PC2-400 Great Lakes marine diesel engine components are analyzed. Appropriate censored lifetime data analysis techniques are presented and applied to obtain the probability density function (PDF) parameter estimates for the entire population when only a portion of that population has failed. Weibull and exponential PDF parameters are evaluated for seven components—namely, cylinder pistons, heads, jackets, liners and O-rings, connecting rod bearings, fuel cams, and turbochargers. Reliability and hazard functions for these items are presented and discussed. It is shown that the exponential model is inappropriate for these items.
