Abstract
Multivariate statistical procedure has been used to compare various alternate fuels based on the residue formation on selected engine parts.
The results from the Multivariate Analysis of Variance procedure which does the simultaneous comparison of the chosen response variables are presented. The assumptions for this test procedure are given. Problems which could affect the validity of the statistical procedures for the endurance test are discussed.
Data from a 200-hour EHA laboratory screening endurance test is used to illustrate the statistical methods.
Results from the statistical analysis of the experimental data were in close agreement with the engineering interpretation of the observed differences between fuels. Critical engineering interpretation of the statistical results is still required due to the high sensitivity of the statistical analysis.
