【 摘 要 】

The work carried out deals with effect of variation in compression ratio (VCR) on engine performance and emission by applying thermal barrier coating on to engine parts for improving engine performance when biodiesel (mixed milk scum and safflower) is used as alternative fuel and the layer of thermal coating was made of Alumina-Titanium oxide (Al2O3/TiO2) plasma coated on to the base of NiCrAl. The work also deal with experimental analysis of performance and exhaust emission characteristics of diesel-biodiesel blends use in single cylinder 4-stroke with varying compression ratio (VCR) i.e. 14:1, 16:1- 18:1 using biodiesel blends i.e. B20, B40,B60,B80 and B100 with load variation from a load to full load and compare with base. The result showed a reduction in specific fuel consumption.CO and HC emissions are slightly more than the conventional coated diesel engine at low and medium loads but lesser at higher load where NOx is reduced.
