“…The introduction of non-conventional combustion regimes is seen as a possible key point. This is the case for PCCI (Premixed Controlled Compression Ignition), LTC (Low Temperature Combustion) and HCCI combustions, Figure 10 [60]. As shown, the tendency is to obtain a combustion process characterized by lower temperatures and a higher level of local air-excess ratio, in order to get off the region relative to NO x and soot emissions.…”

“…Soot exhaust emissions are, in turn, reduced by lowering the local equivalence ratio and by re-oxidation of formed soot (e.g. Neely et al, 2005;Dale et al, 2007). An effective multiple injection scheme may exploit, higher injection pressure to accelerate the atomization process, a pilot or pre-injection(s) to enhance premixing and, possibly, reduce noise, as well as post-injection(s), either to promote soot oxidation, or to trigger regeneration in diesel particulate filters (DPFs) (e.g.…”

“…On account of the low volatility of diesel fuel, the early injection with the conventional wide spray angle injector in low ambient gas density condition can result in very serious spray impingement and wall wetting, contributing to a dramatic increase in emissions and incomplete combustion or misfire in the low load range. Using a narrow spray angle to contain the spray in the bowl [19] or multiple injections [11,13,16] could be possible solutions.…”
