“…In other recent work by some of the current authors [29], oil was deliberately directly injected into the charge of a full bore optical engine, with the transport properties of the lubricant indicated to have some effect on the likelihood of pre-ignition and knock occurring. These observations were in good agreement with those reported simultaneously elsewhere in a full metal engine by Wellings and co-workers using identical lubricant blends [30].…”

“…W związku z powyższym istnieje kilka teorii co do mechanizmu powstawania omawianego zjawiska i czynników na nie wpływających. 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).…”

“…In addition, the examination of various lubricating oil detergents revealed that calcium in particular could promote pre-ignition. In (Welling et al, 2014;Long et al, 2016), a standard injector was used to insert oil into the combustion chamber of a non-optical test engine in order to artificially induce pre-ignitions.…”
