Investigation on Performance of 4-Stroke Diesel Engine by Using Waste Cooking Oil Based Biodiesel

There is a rapid increase in the pollution level as the global demand for fossil fuels increases. Burning fossil fuels leads to the release of greenhouse gas and other toxic pollutants into the environment, and that level has reached the limit. For the last few decades, scientists worldwide have been looking for a safe, eco-friendly alternative energy source. One of the prime alternative forms of energy is green bio diesel. Biodiesel is analternativefuelthatcanbeuseddirectlyindieselengineaspureorblendedwithdieselfuel. The present work is the production of the biodiesel from utilizing waste cooking oil by using transesterification reaction, methyl alcohol and glycerol as catalyst. Hear tested for different properties (density, viscosity, calorific valve, flash and fire point) for waste cooking oil. The effect of biofuel in the performance characteristics examined in diesel engine. Performance parameters like break power break thermal efficiency, break fuel consumption will be calculated with different blends and exhaust emissions like carbon dioxide, NOx, Sulphur dioxide, smoke and particulate matters.
