Experimental Investigation of Bio-Butanol Addition into Diesel, Biodiesel, and Diesel-Biodiesel blends on the Thermal Release of the Power Pack

Biodiesel and Bio-Butanol are among the renewable fuels that are manufactured from the waste cooking oil and the cut waste vegetables and fruits. This research work includes the investigation of volume of bio-butanol that can be blended with diesel, biodiesel and diesel-biodiesel blends such that the properties of the final blend along with the test of solubility under 25 deg Celsius for sixty days in a controlled environment, possesses competent properties with respect to base values of diesel. Following this an investigation of performance, combustion and emission characteristics of diesel power pack has been performed. The results indicate that biobutanol can be blended with diesel up to 20%, up to 50% with diesel-biodiesel (20%), and 35% with biodiesel. The test in the power pack depicts that the thermal efficiency, smoke , carbon monoxide and hydrocarbons from the fueled power pack are found to be higher when comparing the reference values of diesel. However, the values of fuel consumption, energy consumption of the power pack when operated with the fuel blends are lower in higher brake powers. The peak cylinder pressure, delay of the ignition of the fuel blends, net heat release rate are found to be competent comparing the reference of diesel powered power pack. This study concludes that the fuel blend biodiesel-bio-butanol which possesses only renewable fuels that are manufactured from waste and this saves the pollution of the land as well as garbage disposal cost. Also, this fuel can be used without major modifications of the operating parameters of the power pack. The cost of the fuels are approximately 50% of the cost of the fossil fuels.
