Abstract

The ignition behavior of gasoline and two-and three-component surrogate fuels has been explored experimentally. Experiments were performed in a motored CFR engine operating in HCCI mode over a range of operating conditions representative of those of interest for a low-temperature combustion regime. For each fuel blend, the critical compression ratio (CCR - lowest compression ratio at which the main ignition occurs) was determined for a range of intake pressures, by varying the compression ratio for a fixed intake temperature and equivalence ratio. A simplified CFD model that considers detailed chemical kinetics and wall heat transfer was developed to simulate the experiments. The model is able to reproduce the measured CCRs for n-heptane and PRF80 fuels, depending on the chemical mechanism used. The model will then be applied to three-component and larger surrogates.
