Mathematical modeling for the performance and emission parameters of dual-fuel diesel engine using producer gas as secondary fuel

Abstract: This study presents mathematical modeling of some experimental investigations for different combinations of producer gas and diesel over a wide range of load conditions in dual-fuel operation of a four-cylinder turbocharged diesel engine. Response variables considered in this work were brake thermal efficiency, un-burnt hydrocarbons, carbon monoxide, and oxides of nitrogen. Mathematical models were developed to correlate the input parameters like gaseous fuel substitution and load with response variables. The developed models can be used to predict the responses for different values of gaseous fuel substitution (GFS) and load. Response surface methodology (RSM) has been applied for developing the models using the techniques of design of experiments and multi-linear regression analysis. General factorial design was used to plan the experiments. Second-order response surface models were found to be most suitable in the present work. Analysis of variance (ANOVA) of the experimental results at 95 % confidence level reveals that the developed models are significant. Comparison of experimental output with those predicted by the developed models showed close proximity having high correlation coefficients R 2 for the various response variables.
