An improved diethyl ether (DEE) reaction mechanism consisting of 174 species and 973 reactions has been proposed. The present model is derived from an original model of Yasunaga et al. [A multiple shock tube and chemical kinetic modeling study of diethyl ether pyrolysis and oxidationYasunagaK.GillespieF.SimmieJ. M.CurranH. J.KuraguchiY.HoshikawaH.YamaneM.HidakaY. Yasunaga, K. Gillespie, F. Simmie, J. M. Curran, H. J. Kuraguchi, Y. Hoshikawa, H. Yamane, M. Hidaka, Y. J. Phys. Chem. A201011490989109]. On the basis of shock tube results in the temperature range of 900–1900 K, pressure range of 1–40 bar, and equivalence ratios of 0.5–2 as well as rapid compression machine (RCM) measurements of a stoichiometric DEE/O2/inert gas mixture at temperatures of 500–900 K and pressures of 3–4 bar, the ignition delay times (IDTs) were validated. Two-stage ignition at temperatures below 650 K and negative temperature coefficient (NTC) behavior at temperatures between 621 and 746 K are observed. In addition, the freely propagating flame velocities of a stoichiometric DEE/air mixture were validated at various temperatures as well. Using directed relation graph (DRG)-based methods for the improved mechanism reduction, a reduced mechanism composed of 80 species and 329 reactions has been achieved. Calculations for IDTs, laminar flame velocities, and temperature and species profiles using the reduced mechanism show very close agreement with those obtained using the improved mechanism. Meanwhile, sensitivity analyses of the burning velocity and IDT for the improved and reduced mechanisms were performed. Competing reactions related to DEE + OH and consumption of C2H5OC2H4s and HO2 were identified as being important for IDTs at various temperatures.

Researchers have studied on alternative fuels that can be used with gasoline and diesel fuels. Alternative fuels such as hydrogen, acetylene, natural gas, ethanol and biofuels also uses in internal combustion engines. Hydrogen in the gas phase is about 14 times lighter than the air. Moreover, it is the cleanest fuel in the world. On the other hand because of its high ignition limit (4-75%), low ignition energy, needs special design to use as pure hydrogen in internal combustion engines. It is proved that hydrogen improves the combustion, emissions and performance, when is added as 20% to fuels. Natural gas is generally consisting of methane (85-96%) and it can be used in both petrol and diesel engines. Ethanol can be used as pure fuel or mixed with different fuels in internal combustion engines. In this section, the effects of natural gas, hydrogen, natural gas + hydrogen (HCNG), ethanol, ethanol + gasoline, ethanol + hydrogen, acetylene, acetylene + gasoline mixtures on engine performance and emissions have been examined.
