Influence of Varying Compression Ratio of a Compression Ignition Engine Fueled with B20 Blends of Sea Mango Biodiesel

The ever-worsening environmental situation brought on by the huge use of fossil fuels has ramped up biodiesel production. Several studies have shown that a 20% biodiesel-diesel blend (B20) could be best for utility in compression ignition (CI) engine. present study focuses characteristics variable ratio (VCR) engine running with B20 sea mango at ratios 16:1, 17:1 and 18:1. VCR is technology which permits to modify its improve fuel economy under varying loads. experimental results reveal an improvement 5.27% 6.25% BTE as well SFC mix, respectively, (CR) 18:1 against diesel standard CR, 17:1. At CR 18:1, CO, HC smoke emissions full load were 26.78%, 37.76% 23.44%, correspondingly lower than those CR. However, was found higher NOx all CRs. least noted although it 0.77% combustion also improved findings this indicate utilized replace without any modifications.
