Study on Alternate Fuels and Their Effect on Particulate Emissions from GDI Engines
Kapitel i bok, 2020

With strict environmental legislations and to reduce related health hazards, there is immense focus on reducing particulates from gasoline direct injection engines. With increasing use of biofuels in the market, their blends with hydrocarbon fuels are also being considered as cleaner alternatives to gasoline. This chapter confers the addition of oxygenates to gasoline and their capacity to reduce sooting tendency compared to gasoline. Challenges related to optimizing combustion by appropriately choosing engine parameters such as start of ignition, duration of injection, etc. have been addressed. Optimizing combustion can reduce the particulate emissions, by sometimes increasing efficiency. Oxygenated fuels always have the advantage of higher oxidation of soot formed inside the cylinder, which further reduces particulate emissions. Towards the end of this chapter, disadvantages of using oxygenated fuel blends or alternate fuels are discussed.
