“…where f m & and j u are the mass flow rate and the velocity of fuel at the nozzle exit, as m & the entrainment rate with swirl flow effect, which is calculated according to the equation proposed by Kau et al (6) , and s u the average swirl velocity over the total spray 5,…”

“…In this study, the ratio (R MS ) of the momentum from entrained gas over the total momentum in the spray, which is calculated by equation (6), is assumed to represent the degree of spray deflection instead of θ 1 and θ 2 in the equation (5). The proportional coefficient for R SA was determined based on the heat release rates for the case with pilot injection quantity of 6 mm 3 , and the same value was used for other pilot injection quantities.…”

In this study, a phenomenological combustion model, which had been developed based on a stochastic combustion model for simulating combustion with multi-stage injection in diesel engines, was improved to estimate the NOx and soot emissions with modifications in the model for the interaction of sprays from sequent injection stages. Model validation was performed by comparison with experimental data from a single-cylinder diesel engine. To understand the variation of NOx and soot production with injection conditions, analysis of combustion process was conducted based on the calculation results from different injection parameters including injection timing and quantity.
