Emissions analysis on second generation biodiesel

Abstract

CNSBD can be used as a fuel without any modification in existing CI engine.

Pentanol reduces HC, CO, NO_x and Smoke emissions significantly.

New and next generation alternative fuel is employed.

Blending of CNSBD with pentanol resulted in no separation of phases and found miscible.

This work investigates the effect of adding pentanol with biodiesel derived from cashew nut shell on its emissions characteristics is conducted in stationery diesel engine. The main purpose of this work is intended to reduce the emissions by fuelling biodiesel derived from cashew nut shell and the pentanol blends. Cashew nut shell biodiesel is prepared by transesterification process. Oxygenated additive used in the work is Pentanol. The experiment is conducted using four test fuels such as, biodiesel derived from cashew nut shell (CNSBD), a fuel containing 90% cashew nut shell biodiesel and 10% pentanol (CNSBD90P10), a fuel containing 80% cashew nut shell biodiesel and 20% pentanol (CNSBD80P20) and neat diesel. Experimental work concluded that by adding 10% of pentanol to cashew nut shell biodiesel 10.1%, 2.6%, 5.1% and 2.1%reduction in CO, HC, NO_x and Smoke emissions were observed respectively. Further by fueling with these blends, no modifications in engines were required.
