Factors that Affect BSFC and Emissions for Diesel Engines: Part 1 - Presentation of Concepts 870343
The per cylinder displacement in cubic centimeters (PCDICC) vs. brake specific fuel consumption (BSFC) have been plotted for both DI and IDI diesel engines. The smallest and largest PCDICC are 25.7 to 2,000,000. It was found for the DI engines that the lowest to the highest (BSFC) ranged from approximately 155 to 450. In terms of ratios these turn out to be about 2.9. Reasons for the increase in BSFC with decrease in PCDICC are presented. Background material are presented to help in explaining the trends experienced. Boundary conditions of the injected fuel as to duration, drop size, and their effect on BSFC, emissions are postulated.
