- Summary:
- To mitigate the global warming and to develop sustainable transportation, investigations on combustion properties of carbon neutral fuels id est, electro-fuels and bio-fuels such as propanol and butanol are essential. In the past, there were very limited researches concerning the fuel-lean combustion of those fuels, which is however a promising method for reducing the NOx emissions. Moreover, the literature chemical kinetic mechanisms have not been widely validated against the fuel-lean combustion data. Ignition delay time (IDT) is one key parameter and is widely used for validation of chemical kinetic mechanisms. The measurements of IDTs of diluted 1-propanol (nC3H7OH, CH3CH2CH2OH) and 1-butanol (nC4H9OH, CH3CH2CH2CH2OH) mixtures (with 90% bath gas (Ar+N2)) were therefore conducted in a rapid compression machine (RCM), at temperatures between 800 and 1000 K, pressures of 20 and 40 bar, under lean combustion conditions with equivalence ratios (ф) of 0.25, 0.5 and 0.9. The IDTs of 1-propanol are notably longer than those of 1-butanol at the same conditions. The obtained experimental data were further compared with simulated results applying literature chemical kinetic mechanisms. Moreover, the influences of temperature, pressure, and equivalence ratio on IDTs were characterized by sensitivity analyses. The reactions of fuel molecules with HO2 and OH radicals are dominant for the autoignition of both 1-propanol and 1-butanol
