Abstract—Although many varieties of vegetable oils do have characteristics similar to that of diesel, but varieties of problems are encountered on prolonged use of vegetable oils in the existing design of engines. To address these problems, transesterification is found to be the best, but, it has its own problems and can not be adopted at rural sites. To run the engines directly with straight vegetable oils, suitable modification in the engine is required. A low cost modification kit is developed for retrofitting on small power agricultural diesel engines. Once the kit is fitted on the engine, it can easily substitute upto 60% of diesel with vegetable oils of local origin. The engine delivers comparable power, efficiency and lower emissions of unburnt hydrocarbons, carbon monoxide and smoke and runs smoothly without effect on life.
Index Terms—Diesel engine, modification kit, vegetable oil.
