INVESTIGATION AND ANALYSIS OF DIESEL ENGINE USING BIO DIESEL

This study represents the analysis of smoke of biodiesel by using smoke tester. In this article biodiesel is taken as a fuel instead of diesel and quantity of emitted pollutants HC and CO is evaluated by taking different quantity of biodiesel at different load. Biodiesel is a diesel fuel that is made by reacting vegetable oil (cooking oil) with other common chemicals. Soybean oil is currently a major feedstock for production of biodiesel. The most common method of biodiesel production is a reaction of vegetable oils or animal fats with meth anolor ethanol in the presence of sodium hydroxide (which acts as a catalyst). The transeste rification reaction yields methyl or ethyl esters (biodiesel) and a byproduct of glycerin. Biodiesel is not straight vegetable oil burned in a diesel engine. Biodiesel has better lubricating properties and much higher cetane rating than today's low sulfur diesel fuels. Biodiesel addition reduces fuel system wear and in low levels in high pressure systems increases the life of the fuel injection equipment that relies on the fuel for its lubrication .
