Feasibility analysis of admitting gasified waste vegetable oil and non-edible oil blends with diesel in CI engine

The disposal of used waste vegetable oil is a significant concern from the pollution point of view. Several studies have already been made to produce biodiesel/blending with diesel in CI engines. However, the cost benefit analysis makes this process non-viable. Also, several works of literature are available in the admitting of non-edible oil blends in CI engines. This paper analyses the admitting the gasified waste vegetable oil (WVO) with non-edible oil (NEO) in CI engine. The mixture of WVO and NEO has been auto-gasified before admitting them in CI engine. Auto gasification is converting the solid combustible waste into the gaseous product with bio-oxygen and catalytic ash. This way, the temperature of the gasification process is reduced and makes direct admission is feasible. From the various trails, it has been found that the optimised performance ratio for the WVO and NEO mixture is 50:50. The cost-benefit analysis of bio diesel production and usage in CI engine has been analysed and reported in this paper. The EIA of WVO disposal has also been carefully analysed and reported.
