| 1 | Development and testing of a detailed kinetic mechanism of natural gas combustion in internal combustion engine显示文摘A detailed chemical mechanism to describe the combustion of natural gas in internal combustion (IC) engine has been developed,which is consisting of 233 reversible reactions and 79 species.This mechanism accounts for the oxidation of methane,ethane,propane and nitrogen.It has been tested using IC engine model of CHEMKIN 4.1.1 and experimental measurements.The performance of the proposed mechanism was evaluated at various equivalence ratios (φ=0.6 to φ=1.3),initial reactor conditions (Tini=500 to 3500 ℃;Pini=1.0 to 10 atm) and engine speed (2000-7000 rpm).The proposed kinetic mechanism shows good concordances with GRI3.0 mechanism especially in the prediction of temperature,pressure and major product species (H2O,CO2) profiles at stoichiometric conditions (φ=1.0).The experimental results of measured cylinder pressure,species fractions were also in agreement with simulation results derived from the proposed kinetic mechanism.The proposed mechanism successfully predicts the formation of gaseous pollutants (CO,NO,NO2,NH3) in the engine exhaust.Although there are some discrepancies among each simulation profile,the proposed detailed mechanism is good to represent the combustion of natural gas in IC engine. | M.Mansha A.R.Saleemi Badar M.Ghauri Naveed Ramzan | 2010 | Journal of Natural Gas Chemistry2010，19，2： | 2 |
