| Abstract |
This report documents the performance evaluations of Detroit Diesel Corporation 6V-53N and Cummins NH-220G engines operating largely on broadened military specification fuels, MIL-F-16884H. The performance evaluations also included a fundamental study of the relationship of fuel properties to various combustion phenomena measured in one cylinder of each test engine. Included are engine and test fuel specifications, engine performance analysis, engine operating data, and test fuel data. Fuel property correlations with engine combustion variables were developed using a multivariate analysis of fuel properties with engine performance variables. The power production and fuel consumption correlations were dominated by the test point variables speed and load included as independent variables. Additional multivariate analysis performed utilizing a transformation of the independent variable load, revealed acceptable fuel property correlations for power and fuel consumption. Kinematic viscosity, net heat of combustion, specific gravity, and hydrogen content influenced the power and fuel consumption of the Cummins NH-220G. The power and fuel consumption of the Detroit Diesel Corporation 6V-53N was influenced by kinematic viscosity, net heat of combustion, specific gravity, hydrogen content, aniline point, and boiling point distribution. |
