Exhaust emission from engine combustion is concerned increasingly to environmental effect. Fuel additives mixed for reduction of the exhaust are more interested based on no modification of the engine. In this study, exhaust emission and performance of an indirect injection diesel engine were investigated under the various fuel test conditions with mixing additive based organic solution. The various fractions of palm oil biodiesel (POB) in the rest of diesel fuel from 2% to 100% denoted as B2 up to B100, respectively were considered. The improvement of POB fuel properties with using organic additive based oxidative desulfurization in the blended fuels in order to allow in the set regulations of Thai Department of Energy Business (DOEB). The modified fuels by blending the 0.1g additive in 2.5 liters diesel fuel tested were prepared and measured the physical properties such as viscosity, cetane number, flash point, heating value, and carbon residue of the modified fuels under ASTM standard test methods. The effect of the additive in POB blended fuel on CO, CO2, and NOx was investigated in this study. Comparing with the same fraction of POB blend without additive, the significant improvement of POB properties of all POB fuels adding the organic additive was obtained. Their properties for high POB fraction of B40 with additive are still allowed under the set regulations of DOEB. In addition, the experimental results showed the effective decrease of the exhaust emissions from using the organic additive in comparison with POB fuels in the same fraction.
