Ignition delay times of methane/diethyl ether (DEE) blends measured in a rapid compression machine (RCM)

Diethyl ether (DEE) is an interesting species for combustion at least two reasons: On the one hand, it used as a kind of ”worst case” reference substance studies concerned with prevention accidental ignition events. other also candidate bio-fuel. For this reason, in work, auto-ignition different /DEE-mixtures (90/10 and 95/5 mol-% /DEE) are studied rapid compression machine (RCM). In RCM, gas mixture compressed piston–cylinder device up to 20 bar held under isochoric conditions top dead center. Auto-ignition occurs after delay time (IDT). IDTs measured temperatures ranging between 515 925 K, both, stoichiometric fuel-rich mixtures (equivalence ratio ?=2). The experimental data compared results simulations involving detailed chemistry, well fuels investigated same RCM (results from literature).
