چکیده انگلیسی
In the present analysis, the dissemination of dimethyl ether (DME) as an alternative fuel with the charged air inside the HCCI engine chamber until accomplishing the burning procedure have been numerically expected by utilizing CFD with detailed chemical kinetics mechanism. The physical technique of the ignition and pollution arrangement in the engine barrel with DME fuel is examined with a developed hydrocarbon reaction mechanism at various HCCI engine loads. The mechanism is including 81 chemical species and 362 basic chemical reactions. Along these lines, the used CFD/discipline code predicts the admittance of the fuel spray, ignition, and pollutant development of DME as a biodiesel fuel. The split injection technique has been used to inject the dimethyl ether remotely at the engine admission tube. The in-cylinder flow field enhances farther the engine chamber fuel/air distribution. The outcomes showed that the blend of DME fuel with charged air is exact and efficient to accomplish the in-barrel blend homogeneity. It is anticipated that, under every engine working condition the production of the methyl radical is considered as imperative part in dimethyl ether pyrolysis and oxidation. In the meantime, the formaldehyde sub-component is a huge division of the general dimethyl ether (DME) ignition system.
