Performance, Emission and Combustion Characteristics of a VCR Engine Fueled with Sea Mango Biodiesel/Diesel Blends

The constant emission of greenhouse gases into the atmosphere, due to continuous burning fossil fuels, has been driving researchers develop an environmentally friendly alternative fuel solution. An experimental investigation was conducted on a laboratory scale, evaluate physicochemical qualities, performance, emissions, and combustion characteristics sea mango oil biodiesel blends pure diesel single-cylinder, variable compression ratio (VCR) engine. Tests were at 1500 rpm, 210 bar, 23° bTDC, under varying loading circumstances 0, 3, 6, 9, 12 kgs, ratios 16:1, 17:1, 18:1, respectively. findings revealed that higher (CRs) improve emission, At CR BTHE, SFC, EGT improved by 8.78%, 11.18%, 2.52% more than standard (17:1). CO, HC, smoke emissions also lowered 14.65%, 18.56%, 11.56%, respectively, 18:1. NOx increased 6.77%. improved, with increase in CR. this show can be used as no engine modifications.
