Biodiesel Extracted from Waste Vegetable Oil as an Alternative Fuel for Diesel Engine: Performance Evaluation of Kirlosker 5 kW Engine
These days, we are facing challenges like energy depletion, environmental issue, and rising costs of petroleum, which leads to research for new and renewable energy resources. Among all renewable energy, biodiesel has several advantages as an alternative fuel in terms of availability, performance, and emission characteristics. In this paper, biodiesel is derived from waste vegetable oil and its performance evaluation has been carried on single cylinder diesel engine, make Kirlosker TV1 at 1500 RPM. The diesel engine is performed successfully on all the biodiesel blends without any engine modifications. The highest SFC for biodiesel was 10% more than the diesel. The maximum variation in BTE of diesel has been seen at 1.5 kW loads and was 19.95% as compared to 60% biodiesel blend. At peak load, the air–fuel ratio demand for diesel was 8.83% more than the 100% biodiesel. Up to 20% biodiesel blend, the diesel engine performance was almost similar to diesel without any lag but after that the performance slightly reduces. Hence, biodiesel from waste vegetable oil may be considered as a low-cost renewable substitute for diesel fuel.
