Abstract

Petroleum products such as petrol and diesels are being used as a fuel to the running of Internal Combustion Engines. Day by day number of automobiles is increasing because of urbanization and hence demands for the petroleum products also; as a result its rate of consumption is increasing from year to year. If the trend will continue the whole world may suffer from shortage of petroleum products. Therefore it is necessary to find new alternative fuels by those the same IC engine could work. As we know so far alternative fuel based engines are giving lower efficiency as compared to conventional petroleum based fuel so to reduce the fuel consumption and at the same time to improve the performance of IC engine; it is necessary to find out some additives to mix it with the mixture of petroleum product and alternative fuel and one can formulate a new fuel.

Bio-origin fuels have been found as a possible alternative energy source to fulfill the above demand in automobile sector. Using biodiesel as a fuel results in less pollution to environment according to different researches, but it is unable to give same brake power or thermal efficiency what we get with pure petroleum products. So the focus of study is given to examine the improvement of the performance of CI engine using diesel and bio-diesel by adding nano-aluminum oxide (n-Al2O3) as an additive. Nano-Al2O3 have better combustion characteristics and enhanced surface area to volume ratio which results in better oxidation of the fuel mixture and hence enhances the combustion efficiency of the test fuel.
