Effect of antioxidant on performance and emission characteristics of diesel engine fuelled with diesel-palm biodiesel blends -A review study

I.C. Engine and Automobile Engineering

In conventional CI engine diesel is used as a fuel which provides better power, efficiency and basic specific fuel consumption. But it increases the CO2, CO, HC, SOX and NOx emission. Which affect the environment and human health. It causes global warming and greenhouse effect and sometimes acid rain too. Also diesel fuel is nonrenewable energy resources and increases our dependency for importing fuel on other country. Due to depleting the fossil fuel and increasing effect of environment pollution from this fuel demands an ecofriendly alternative which can be used in diesel engine without any major modification. This study presents a detailed analysis of the effect of antioxidant on performance and emission characteristics of diesel engine fuelled with diesel-palm biodiesel blends. It is observed that using palm biodiesel in diesel engine emits lower CO and HC and emits higher NOx. Higher level of NOx emission can be reduced by adding phenol group antioxidant in biodiesel and its blend.
