“…This is supported by the work of Takeuchi et al [83], who found that a tendency toward LSPI correlates well with the auto-ignition temperatures of lubricants. Among the various physical and chemical properties of base stocks, viscosity shows the highest correlation with pre-ignition events.…”

“…Kassai et al [86] observed that Ca additives only had an effect in premixed PRF/air mixtures, especially with lower research octane number (RON) values, while no noticeable effect was observed with a premixed methane/air mixture. In contrast to Ca, Zn and Mo added to the oil in the form of zinc dialkyldithiophosphate (ZnDTP) and molybdenum dialkyldithiocarbamate (MoDTC), respectively, are regarded as pre-ignition inhibitors [83,86,88,89,[91][92][93][94]. However, Hayakawa et al [95] reported that adding ZnDTP and MoDTC up to 800 and 980 ppm to the fuel had no effect on fuel auto-ignition.…”

“…Koncepcja najczęściej cytowana w literaturze zakłada, że najważniejszymi czynnikami mającymi wpływ na proces nienormalnego spalania typu LSPI jest konstrukcja silnika, warunki jego pracy i właściwości silnikowego oleju smarowego w powiązaniu z właściwościami paliwa (Magar et al, 2015;Döhler i Pritze, 2013;Welling et al, 2014). Badania przeprowadzone w ośrodku badawczym firmy Toyota, ale także firm Ford oraz GM wskazały na duże znaczenie rozpraszania w komorze spalania silnika kropelek smarowego oleju silnikowego, mogącego stanowić źródło powstania LSPI (Takeuchi et al, 2012;Dingle et al, 2014;Qi et al, 2014;Li et al, 2019). W silniku ZI z bezpośrednim wtryskiem paliwa strugi rozpylanego w komorach spalania paliwa omywają ścianki tulei cylindrowych, powodując rozcieńczanie pokrywającego je filmu smarowego oleju silnikowego.…”

“…2. The area arising from the LSPI phenomenon in comparison with the phenomenon of conventional knocking mają bardzo duży wpływ na powstawanie i rozwój zjawiska LSPI (Takeuchi et al, 2012;Yasueda et al, 2013;Spicher et al, 2016).…”

“…[8][9][10] The engine lubricant oil also influences the LSPI, which is likely to occur when oil with a low autoignition temperature at high pressure is used. 11 Some articles have reported that oil additives affect the LSPI. 9,[11][12][13][14][15][16] Especially, Ca additives increase the frequency of LSPI, and molybdenum dialkyldithiocarbamate (MoDTC) and zinc dialkyldithiophosphate (ZnDTP) decrease the frequency of LSPI.…”
