Understanding optimal engine operating strategies for gasoline-fueled HCCI engines using crank-angle resolved exergy analysis
This study couples a crank-angle resolved exergy analysis methodology with a multi-zone chemical kinetic model of a gasoline-fueled HCCI engine to quantify exergy loss mechanisms and understand how the losses change with different HCCI engine operating conditions. The in-cylinder exergy loss mechanisms are identified as losses to combustion, heat loss, unburned species, and physical exergy lost to exhaust gases.
