Abstract
Experimental ignition delays for 2-methylfuran (2MF) were measured using a rapid compression machine at an equivalence ratio of 1.0 with an oxygen concentration of 4.1% in nitrogen and argon, in the temperature range 970-1050 K and pressure range 2.80-2.95 MPa. The measured ignition delays were compared with the numerical predictions. The ignition delays were found to decrease with an increase in the temperature and the simulated ignition delays were in reasonable agreement with those obtained from experiments. In addition, the ignition delays for primary reference fuel (PRF) 90, PRF 90 / 2MF (PRF 90: 70 vol%, 2MF: 30 vol%), and PRF 90 / ethanol (PRF 90: 70 vol%, ethanol: 30 vol%) blend fuels were measured. The addition of 2MF and ethanol to PRF 90 decreased the ignition delays. The ignition delays for PRF 90 / 2MF blend fuel were longer than those for PRF 90 / ethanol blend fuel. A detailed kinetic model for PRF / 2MF blend fuel was constructed, which reasonably predicted the experimental results.
