Impact of second-generation alcohols on emission characteristics of biodiesel

ABSTRACT

An effective alternative for the non-renewable fuel is vegetable oil. The major properties of vegetable oil that oppose the above statement is its high viscosity and low volatility, which could lead to several problems in compression ignition engines. So, the viable method to make it suitable for using in Compression Ignition engine is converting the same to biodiesel, that is, vegetable oil esters using the process of transesterification. During this study, the emission characteristics of a direct injection diesel engine that is fuelled with a blend of mustard oil biodiesel and n-amyl alcohol are compared. The test has been performed at a steady-state condition in a single-cylinder direct injection diesel engine at a constant speed of 1500 rpm. The test results revealed a significant reduction in the emissions like smoke and oxides of nitrogen.
