Experimental investigation on performance emission and combustion characteristics of a di diesel engine using jojoba oil as a fuel

Abstract

Due to the quick advancements in the usage of vehicles and rejuvenation of present world the import of the petroleum based fuels keeps increasing. The demanding cost of petroleum fuels and its efficacy in curbing the emission of green house gases has made the alternating fuel a promising one. These fuels are categorized as mineral and biological alternate fuels based on the source. The mineral based oils are non-renewable and produce greenhouse gas emission but biological based fuels are renewable and ecofriendly. Many biofuels had been identified, one among those is the plant oil,which has a high cetane number and can be used and tested in the CI engines with and without fuel modifications. Generally plant oils possess high viscosity, poor volatility, heavier molecular structure and unsaturation and hence it cannot be used in neat formin the CI engine. However, the neat oils upto 20% by volume would not cause any problem. The proportions more than 20% causes adverse engine related issues such as severe combustion deterioration which leads to carbon deposition, lube oil dilution and smokey exhaust. newline
