- Summary:
- In this work, the effect of ozone, hydrogen, carbon monoxide, and exhaust gas recirculation addition to Hatermann gasoline combustion was investigated. Thus, the laminar and turbulent velocities of these blends were experimentally determined using spherically propagating premixed flames in a constant volume combustion vessel. Stoichiometric mixtures of two initial pressure (0.1 and 0.5 MPa) were tested along with two initial temperature of 358 and 373 K. Relative to the laminar flames, turbulent burning velocity of two turbulence intensities of 0.4 and 1.2 m/s are reported. Two initial mixture pressure of Po = 0.1 and 0.5 MPa were investigated at two initial mixture temperatures (358 K and 373 K). Enhancement in initial temperature and pressure results in a significant increase in laminar burning velocity compared to the base fuel (Haltermann gasoline). With 40% (by mass) addition of synthetic EGR (20% CO2 80% N2), successful propagation of flame was not attained; however, the addition of ternary additives blend improves the kinetics of the combustible mixture to grow a fully propagating flame. The presence of ternary additive limits the reduction of laminar burning velocity to 33% as compared to base fuel (43% reduction), with 20% EGR addition. Increasing turbulence intensity led toward an enhancement in turbulent burning velocity due to increased wrinkling of the flame front. The addition of 10% H2 with 5% CO-1000 ppm O3 shows remarkable enhancement (80%) in laminar flame speed as compared to base fuel at stoichiometric
