Impact of alternative fuels on performance and pollutant emissions of a light duty engine tested under the new European driving cycle

► Effect of animal fat biodiesel and GTL fuels on pollutant emissions under controlled NEDC has been studied. ► Regulated gaseous emissions were determined to evaluate the effect of alternative fuels along urban and extraurban cycles. ► The potential of fuels was also quantified through the measurements of smoke opacity and particle concentration. ► Reduction in particulate matter has been observed with the use of GTL and biodiesel fuels.
