摘要: Abstract This paper investigates an experimental study of Alcohols–gasoline Dual-Fuel Spark Ignition (DFSI) Combustion for knock suppression and high fuel efficiency using a gasoline engine with compression ratio. DFSI is organized port-fuel-injection (PFI) oxygenated, latent heat octane number to suppress direct injection (DI) energy density volatility extend load. Systematical comparison about the effect stoichiometric M–G (PFI-Methanol DI-Gasoline), E–G (PFI-Ethanol E85W15–G (PFI-15% water 85% ethanol DI-Gasoline) G–G (PFI-Gasoline on was conducted. For each test, percentage PFI-Alcohol varied from 0% 100%. The effects these combustion modes knock-limit extension, economy, characteristics were investigated. potential approach alternative alcohol fuels in practical engines significant improvement suppression. exhibits better anti-knock performance achieves higher than other modes.
