Modeling and Experiments of Dual-Fuel Engine Combustion and Emissions

A reduced chemical kinetic model for IC engine combustion simulations with primary reference fuels

“…Only reactions from the fuel through ketone decomposition were considered in the optimization, since the reaction steps below this level were common to both iso-octane and n-heptane fuels and they have been successfully validated in numerical models for engine studies [19,38,39].…”

A numerical investigation on combustion and emission characteristics of a dual fuel engine at part load condition

“…In this work, specific temperature is used as the threshold value for transition from ignition to combustion. The ignition delay time is supposed as a period when the cell temperature is less than 1100 K [12,29] and this phase is controlled chemically. The ignition model was used to consider low temperature combustion [29].…”

“…They represented that, the characteristic-time model could predict engine combustion, performance and emission characteristics very well for cases with natural gas up to 90 percent (10 percent diesel pilot quantity). If the energy supplied by the diesel fuel is less than about 10%, a flame propagation model such a Spark Ignition (SI) engine should be used for natural gas combustion [12]. Liu et al studied the dual fuel engine combustion with numerical and experimental methods.…”

A reduced combustion kinetic model for the methanol-gasoline blended fuels on SI engines

“…Therefore, the ignition delay of RMV2 should be optimized. The optimization method used in this step was the rate constant variation, which has already been shown to be an effective technique for ignition delay optimization [42]. According to the results of Opat et al [43], and Ra and Reitz [41], only the reactions above C 4 level were involved.…”
