Analysis of the Diesel Engine Performance Using the Statistical Analysis System Software 861231

For the diesel engine performance analysis, the authors have developed computer programs that are implemented in the Statistical Analysis System (SAS). Programs have been developed specifically for the analysis of the diesel engine performance, residue formation on the internal engine parts, and fuel injection line pressure traces on the different alternative fuels while using EMA cycle.For the diesel engine testing, the consistency of the type of data and the experimental designs makes it possible to develop a system of SAS programs to analyze and report the data. The modularity of these programs makes adaptation from one trial to the next a simple procedure.Results from the analysis of the experimental data were in close agreement with the engineering interpretation of the observed differences between fuels. However, careful engineering interpretation of the results is required due to the high sensitivity of the statistical analysis.
