Abstract

Different alternative fuels have been proposed by various researchers in diesel engines in view of increased NOx and particulate emissions. Out of the various methods proposed, dual fueling is one of the most important techniques that helps solve the different operational problems related to diesel engine combustion and emission. In the current study, modeling and predicting the formation of NOx emission in a duel fuel liquefied petroleum gas (LPG)–diesel engine has been undertaken. Simulations have been conducted for various LPG flow rates at different engine loads and the predicted NOx values are compared with the experimental values. The results found that there is a decent agreement between the forecasted and the investigational results, where the average difference is within 13.7%. Furthermore, it is found that minimum NOx emission was observed for an LPG flow rate in the range of 0.4–0.6 kg/h and when the engine is running with 75% loading.
