WebJun 5, 2016 · The pilot injection timing strongly determines the initial combustion phase and the exhaust emissions of the dual-fuel engine. By appropriate advancing the pilot injection timing, higher BTE, lower THC and CO emissions are achieved. However, NO x … WebOct 7, 2009 · It is kind of annoying because I am trying to set my pilot injection to occur 1500us before the main injection, and because of the extra timing I am getting about …
WebAug 12, 2024 · The pilot injection timing shows minimal influence on the main combustion process. Better performance can be obtained with partially premixed combustion with a slightly late injection timing compared with that of the original (ORG) base case. NOMENCLATURE HPDI High-pressure direct-injection ORG ORiGinal IMO International … Webearly pilot injection timing tends to produce intermediate main ignition delay resulting in a complete combustion process due to long residence time for the reaction of fuel-air (Guntram A. Lechner, Timothy J. Jacobs et al. 2005-01-0167, 2005). As a result, the early pilot injection timing produces the higher in-cylinder pressures leading to ...
WebMay 12, 2024 · If the pilot injection time is short enough or the pilot injection/fuel mass ratio is large enough, the pilot injection creates an acceleration effect for the main injection. Although a shorter injection interval helped to form the acceleration effect, it performed worse in terms of the space utilization and thermo-atmosphere utilization.
