Determination of Performance and Emission Test on a CI Engine by using Algae Oil as an Alternative Fuel

Abstract

Air pollution, which is generated by emissions of hydrocarbons, nitrogen oxides, carbon oxides, and sulphur oxides from the combustion of fossil fuels, is currently the biggest threat to the environment and public health. The fast increase in the consumption of fossil fuels by various factories in recent years has prompted the quest for alternative fuels. These fuels are also known as non-conventional fuels since they can be utilised to replace conventional fuels. Algae oil is one of the most promising possible sources of microbe-derived biofuels. It is widely preferred since it is a long-lasting, environmentally friendly oil with several benefits.  As a result, algae oil has been used to test the performance and emissions of a diesel engine. The blends were created for B5, B10 testing. In which 5% of methanol has mixed and others are raw algae oil (5% for B5 and 10% for B10) and Diesel (90% for B5 and 85% for B10).  For performance analysis, the Kirlosker Engine with 6.97 HP (5.2KW)@1500rpm is employed. Parallel AVL emission analyzers and smoke detectors were connected to the engine's exhaust. All values of gases were displayed and compared. The catalyst used with both B5 and B10 blends was methanol. The use of a better catalyst in future may help in improving the performance of B10 blend, enabling us to use more and more organic algae oil instead of the non- renewable diesel.
