Abstract
In this work autoignition delay times of two multi-component surrogates (high and low RON) were experimentally compared with their target full blend gasoline fuels. The study was conducted in a rapid compression machine (RCM) test facility and a direct test chamber (DTC) charge preparation approach was used for mixture preparation. Experiments were carried over the temperature range of 650K-900K and at 10 bar and 20 bar compressed pressure conditions for equivalence ratios of (Φ =) 0.6-1.3. Dilution in the reactant mixture was varied from 0% to 30% CO2 (by mass), with the O2:N2 mole ratio fixed at 1:3.76. This dilution strategy emulates exhaust gas recirculation (EGR) substitution in spark ignition (SI) engines. The multicomponent surrogate captured the reactivity trends of the gasoline-air mixtures reasonably well in comparison to the single component (iso-octane) surrogate. The trends in the negative temperature coefficient (NTC) region, at both diluted and undiluted conditions, were captured well by the multi-component surrogates. The addition of diluent prolonged the ignition delay times in reference to the undiluted conditions indicating no or weak chemical reactivity due to CO2 addition. The retarding effect of the CO2 dilution was more pronounced in the NTC region when compared to the lower and higher temperature range.
