Introduction/Background: The use of vegetable oils in diesel engines is nearly as old as the diesel engine itself. The inventor of the diesel engine, Rudolf Diesel, reportedly used groundnut (peanut) oil as a fuel for demonstration purposes in 1900 (1). Some other work was carried out on the use of vegetable oils in diesel engines in the 1930's and 1940's. The fuel and energy crises of the late 1970's and early 1980's as well as accompanying concerns about the depletion of the world's non-renewable resources provided the incentives to seek alternatives to conventional, -based fuels. In this context, vegetable oils as fuel for diesel engines were remembered. They now occupy a prominent position in the development of alternative fuels. Hundreds of scientific articles and various other reports from around the world dealing with vegetable oil-based alternative diesel fuels ("biodiesel") have appeared in print. They have advanced from being purely experimental fuels to initial stages of commercialization. Nevertheless, various technical and economic aspects require further improvement of these fuels.

Objectives: 1. To collect the waste vegetable oil from large hotels. 2. To study and characterize the biodiesel produced by waste vegetable oil without trans esterification. 3. Finding of properties like calorific value (CV), viscosity, flash point, fire point, density and various properties of the oil by using laboratory equipment 4. To study the suitability of the oil for running the IC engine. 5. To conduct the performance test and evaluation of the results with respect to the standard fuels. 6. To reduce the cost by using SVO into IC engine.

Methodology:

1. To collect released used cooking oils or waste vegetable oil from large hotels. 2. To Heat the oil to reduce viscosity, and Filter it. 3. Centrifuge the oil (settle down the fine particles down) 4. To investigate the various properties of the waste vegetable oil. 5. To blend the mineral turpentine with released waste from large hotels in various proportions and study the properties of these blends. 6. To arrive at a proper combination of this blend to ensure miscibility and FFA below required limits. 7. To keep the samples for one week. 8. To characterize the methyl Easter so produced by determining Viscosity, Flash & fire Point, Calorific value and Corrosion test. 9. To use these blends in a CI engine and check the performance and emissions.

Results and Conclusion: Experiments were conducted on direct injection compression ignition engine using diesel, waste cooking oil and its blends with turpentine with blend composition varied from 5 to 10% in steps of 2.5%. Base line readings were also generated with existing uncoated diesel engine for the comparative study. The engine speed was kept constant at 1500 rpm and the compression ratio of 17.5, injection timing of 23oC and injection pressure of 230 bar were maintained throughout the experiment.

Future scope: The project can be taken up in large scale and the results are very near to the diesel fuel so can be used as an alternate fuel for the automotives.
