CI engines are very important and famous from the time of their invention; most of the automobiles are run by these engines. In this study, the effect of peanut oil blends with diesel is investigated experimentally and the performance and exhaust emission are recorded. Peanut oil and its 10%, 15%, 20%, 25% blends with diesel are investigated and compared with standard diesel. Experiments were conducted at constant speed of 1200 rpm, full load and at compression ratios of 12.5:1, 15:1, 17.5:1, 20:1 and 22.5:1. The effects of compression ratio on brake power, mechanical efficiency, indicated mean effective pressure and emission characteristics has been investigated and discussed. Comparative measures of CO2, NOx and CO have been presented and discussed. Exhaust gas temperature is very much low for all the blends compared to standard diesel. Increase in compression ratio improves fuel efficiency and power output. The novelty in this work is to permit 4-stroke CI engine manufacturer to change the compression ratio. |
