Abstract

Experiments and surrogate modeling have been preformed to assess the ignition characteristics of naphtha for its use in advance engines. Naphtha, which has low octane number, is proposed as a promising fuel for advanced compression ignition (CI) engines. In this work, Ignition delay times of Haltermann straight run naphtha (HSRN) were measured over wide ranges of pressures (20 and 60 bar), temperatures (620 - 1250 K) and equivalence ratios (0.5, 1 and 2). The naphtha used in this work has research octane number (RON) of 60 and motor octane number (MON) of 58.3. Our experimental data are compared with simulated ignition delay times of three surrogates: primary reference fuel (PRF), toluene primary reference fuel (TPRF), and six-components surrogate. Experimental and simulated ignition delays of the three surrogates show good agreement at high and intermediate temperatures. However, at low temperatures, the multi-component surrogate performs much better than the other two simpler surrogates in capturing the reactivity trends of HSRN.
