Effect of C.R. and load on Performance and Emission Parameters of VCR Diesel Engine

Abstract: In this research paper experimentation is conducted for diesel fuel on Single cylinder 4 stroke VCR diesel Engine at various compression ratios (16,17, and 18) and variousloads(3 kg,6kg,9kg and 12kg) .Results analysis is done to study the effects of load and C.R. on performance parameters like BTE ,Mechanical efficiency and BSFC of the engine and emission parameters like CO,HC and NOx. Results shows that, engine gives better performance at higher load and higher C.R. as value of BTE is higher at higher load and higher CO and HC emissions are decreases with increase in load and C.R but NOx emissions are higher at higher load and higher values of C.R.
