30.4.1 Effect on Engine Performance Characteristics
Results from engine tests conducted with oxygenated
fuels and oxygen-enriched intake air for peak cylinder
pressure, ignition delay, and BSFC are shown for DI die-
sel engines in Figure 30.16 and for IDI diesel engines
in Figure 30.17. Specically, Zannis and Hountalas

2500rpm and at 80% load (BMEP = 5 bar) using three
oxygenated fuels with various aromatic contents. The
