Experimental Study to Reduce Nitric Oxide Emission Using in Cylinder and Post Combustion Strategies in a Compression Ignition Engine

Abstract

Grapeseed oil methyl ester is selected as a base fuel for this research study. The experiments were conducted in a single cylinder, Kirloskar make CI engine with rated power 5.2 kW and constant speed of 1500 rpm. Initially, tests were conducted with base fuels namely, diesel and grapeseed oil biodiesel (GSBD) to understand the performance, combustion and emission parameters. GSBD emits more NO compared to diesel due to their higher oxygen content. At full load condition, NO emission for GSBD is 22% higher than diesel newline
