This paper presents an experimental analysis of performance and emission characteristic of diesel-biodiesel blend use in single cylinder, aspirated with varying compression ration i.e, 14,16,18. using biodiesel diesel blends i.e. B10, B20, B30, B40, B60, B80 and pure biodiesel with load variation from ano load to full load and compared with base cases i.e. engine using diesel as a fuel. The parameters which studied are in performance brake power, brake specific fuel consumption and brake thermal efficiency, in emission carbon monoxide, carbon dioxide, nitrogen oxide and unburned hydrocarbon of diesel engine. It was observed that out of three compression ratios i.e. 14, 16 and 18, compression ratio 18 results of brake thermal efficiency, brake specific fuel consumption and brake power as better results and emission for it was also lower except nitrogen oxide. In diesel-biodiesel blend , B20 having a better performance out of all combination of test fuel and emission of carbon monoxide (CO), carbon dioxide (CO2), unburned hydro carbon (HC) and oxides of nitrogen (NOx) decrease.
