Abstract

In conventional CI engine diesel is used as a fuel which provide better power, efficiency and BSFC but it increase the CO2, CO, HC, SOX and NOx emission. These gases affect the environment and human health. It causes global warming and greenhouse effect and responsible for acid rain too. Diesel is non-renewable energy resources and increase our dependency for importing fuel on other country. Due to depletion of the fossil fuel and increasing hazardous effect on environment pollution an ecofriendly alternative
is needed. It is observed that CI engine can be operated with blend of jatropha biodiesel with diesel blend without design modification. Using these blend in different proportion result shows that NOx emission increases and stability of fuel is also suffer. NOx emission and stability of biodiesel blends is tried to nullify by selecting phenol group antioxidant with different proportion.
