EXPERIMENTAL INVESTIGATION OF UREA-SCR IN C.I. ENGINE FUELLED WITH DIESEL AND JATROPHA BLENDS

Abstract

An Experimental Investigation was conducted to examine the performance and exhaust emission of diesel Engine by using Selective Catalytic Reduction (SCR) concept fuelled with diesel and Biodiesel namely Jatropha ( 25% of Jatropha and 75% Diesel blends). A test was conducted in four cylinder direct injection diesel engine with different loading condition. And the urea with distilled water solution was sprayed at the Exhaust manifold before it enters the SCR setup for different concentrations and the emission parameters were investigated are CO, HC, NOX and Smoke Opacity. Results showed that Biodiesel reduced the NOX and other emission. The result showed that the Biodiesel derived from jatropha oil showed comparable performance in the Selective Catalytic Reduction system (SCR). Results indicated that a maximum of 73.94% of NOX reduction was achieved with constant flow rate of 0.75 lit/hr with a urea concentration of 32.5% by means of the Titanium dioxide catalyst in Selective Catalytic Reduction (SCR) System.
