Abstract
This is a story of Y2 K (yr 2000) in Indian industry. An engine manufacturing company faced the problem of low Lubrication Oil Pressure (LOP) of a six-cylinder diesel engine. The engine under study was used for power generation application. In this paper, we describe how planned Design of Experiment (DOE) was used successfully to resolve the issue of low LOP. Planning or designing an experiment is a well-known technique in statistical literature. What is new is a successful application in resolving the low LOP issue. Hence, we thought of reporting the study in the paper. The paper is written in a tutorial format and would be useful in other studies.
