Effect of compression ratio on the performance of CI engine fuelled with freshwater algae biodiesel

ABSTRACT

Biodiesel is proved to be a better substitute of conventional diesel. Economically good biosource is a needed one. In this study, freshwater algae (micro algae) are used for producing the biodiesel. The fuel properties of the biodiesel sample were tested and found within the limits. The B10 and B20 biodiesel blends with diesel are tested in a single cylinder CI engine. The blends show a better performance in CI engine and the values are closer to the conventional diesel. The important engine parameter compression ratio is also made to vary. At the three compression ratios, the biodiesel’s performance trend is quite comparable with diesel.
