TY  - JOUR
AB  - The work investigates the effect of various post-injection strategies on the flame patterns in a RicardoHydra optical single cylinder light duty diesel engine, operated in a partially premixed combustionmode (PPC), under low load (IMEP: ca. 2.3 bar) low speed (1200 rpm) conditions. The effect of postinjectionfuel amount (12 and 24% of the total fuel quantity per cycle) and post-injection timing (0,5, 10 deg aTDC) are investigated via pressure trace analysis and optical measurements. Flamepropagation is captured by means of high speed flame natural luminosity imaging and of CH, C2and OHline-of-sight chemiluminescence measurements. Results indicate that post-injectionssuppress mixture reactivity but enhances oxidation, and that a larger amount of fuel and/or later postinjection, leads to higher levels of natural luminosity, indicating possible higher soot-out emissions,while post injection close to the main combustion event appears to have a beneficial effect on the sootoxidation processes.
