Abstract
This experimental investigation focuses on production of biodiesel from Waste Fried Oil (WFO) by changing oil to methanol molar ratios and performance analysis of it in diesel engine. High viscosity and poor volatility are the major limitations of waste fried oil for utilization as a fuel in diesel engine. The oil to methanol molar ratios considered for transesterification were 3:1, 6:1 and 9:1. The cost of biodiesel production is presented in this paper and found more economical than mineral diesel. It satisfies the important fuel properties as per ASTM specification of biodiesel.
This paper discusses the performance of biodiesel in a single-cylinder, four-stroke, direct-injection, diesel engine. The performance of engine with mineral diesel has been considered as base line. Biodiesel B50 with molar ratio of 6:1 yielded the highest thermal efficiency 30.2% closer to mineral diesel (31.6%) at rated load. The brake specific fuel consumption for B50 was 0.31 kg/kWh as against 0.29 kg/kWh of diesel. The highest exhaust gas temperature was observed for molar ratio of 3:1 and it was 31°C higher than that of diesel. For daily 6 hours operation for 300 days, it is possible to save Rs 21606 by running the engine on B50(6:1) mode.
