An Experimental Investigation on Physical Properties of Waste Cooked oil and Honge oil as Biodiesel

Rapid growth in civilization, transportation have led to the problems of global warming, harmful emissions causing damage to the earth because of high consumption of the petroleum based fuels. Usage of fossil fuels leads to the increase in global warming causing environmental pollution, these fossil fuels certainly will get exhaust one or the other day. Biodiesel is an alternative fuel for diesel engine. The esters of vegetable oils and animal fats are collectively known as biodiesel. Biodiesel has an energy content of about 12% less than petroleum-based diesel fuel on a mass basis but it is domestic and renewable. It has higher molecular weight, viscosity, density and flash point than diesel fuel. The physical properties of the biodiesel nearly match that of the fossil fuels as well as biodiesel is eco-friendly, economic with good performance characteristics. In this paper investigation is carried out on Waste Cooked oil & Honge oil as biodiesel in different blend ratios as 40%, 60% & 80% in order to study the properties such as kinematic viscosity, flash point and fire point. The results obtained represent kinematic viscosity, flashpoint and fire point values are within the limits of International standard for biodiesel.
