Understanding Low Speed Pre-Ignition Phenomena across Turbo-Charged GDI Engines and Impact on Future Engine Oil Design

Investigation on low-speed pre-ignition from the quantification and identification of engine oil droplets release under ambient pressure conditions

“…With fuel economy standards pushing forward to further reduce emissions, downsizing and turbocharging will continue to be adopted in new gaoline powered vehicles [6,7], and therefore to be operated at regimes (low engine speed) and loads (high load) where LSPI events are more likely to occur. This phenomenon is therefore a setback to continue the development of these technologies and new engine designs, affecting fuel economy improvements and the reduction of emissions [8,9].…”
