Medium-speed diesel engineers: part I-design trends and the use of residual/blended fuels
Fuel costs can exceed 50 percent of the total diesel plant's operational expenditures. To reduce fuel costs, medium-speed engines are now available with improved fuel consumption and ability to burn residual fuels. Part I of this paper reviews these engine and design changes needed for both improved fuel consumption and the ability to burn poorer quality fuels. Characteristics of these fuels and international fuel specifications are discussed. Ignition quality of residual fuels by a modified ASTM D 613 procedure are presented and correlation shown to calculated diesel index and calculated carbon aromaticity index (CCAI). Residual fuel ignition delay effects on combustion pressure rise, fuel consumption, and piston temperature in a laboratory single-cylinder diesel engine are shown.
