Performance and Emission Characteristics of VCR Diesel Engine with Pre Heated Lemon Grass Biodiesel as Fuel

Abstract

Abstract Under this experimental analysis the lemon grass oil was considered, it’s converted into biodiesel as lemon grass biodiesel methyl ester (LGB) through transesterification process. The Kirloskar TV1 was used as the reference fuel in the fuel injection system 4-stroke diesel engine. The lemon grass biodiesel methyl ester (LGB B20) blend B20 is selected because it nearest to the diesel value. The lemon grass biodiesel is preheated at 60°C temperature that is (LGB B20 preheating @ 60°C). The results of the test showed that LGB B20 kinematic viscosity and density gradually decreased with fuel temperature rise. The performance characteristics of Preheating biodiesel is increased the BTE and slightly reduce the BSFC at noted in the full load condition. And the emission characteristics at full load condition of CO, HC and smoke density as decreased, it was observed slight increase of NOx emission.
