USE OF ANTIOXIDANT ADDITIVES FOR NOX MITIGATION IN COMPRESSION IGNITION ENGINE OPERATED WITH BIODIESEL FROM ANNONA OIL

ABSTRACT
The many researchers pointed out that the biodiesel produces reduced carbon monoxide, hydrocarbon, and smoke emission. However there is a slight increase in NOx emission for biodiesel when compared to that of conventional diesel. The addition of antioxidant additives is the effective method for mitigate the NOx emission. Hence, in this research work the effect of antioxidant additives on NOx emission in a annona methyl ester operated Diesel engine has been investigated. The antioxidant additives such as p-phenylenediamine, a-tocopherol acetate, 1, 4-dioxane, and l-ascorbic acid are used in this investigation. Results show that antioxidant additives are very effective in controlling the NOx emission. Among different antioxidant additives, 0.010%-m concentration of p-phenylenedimine additive is optimum for NOx emission reduction up to 42.15% when compared to that of neat biodiesel.
