involves the complication of battery explosions if not properly maintained and used, oil imports put a huge burden on foreign exchange and thus cast negative effects on our economy. This increases the country's dependency on other nations which decreases the net revenue of India and causes huge unemployment status. Availability and infrastructure are the weak points of this scenario, for that Neem oil is widely available as it contains almost 35% of oil, broad area cultivation produces enough oil that could be blended with diesel, besides neem grows in almost all topographic and climatic conditions and are flourished into a fully grown plant within a short span of time, this contributes towards enhancing the forestation which helps in reducing the greenhouse gas emission thus decreasing the ozone depletion potential. Neem contains triglycerides and triterpenoid compounds, saturated fatty acids which are; palmitic, stearic and also contains polyunsaturated fatty acids like; oleic and linoleic acids. Neem is processed by transesterification method by minding the presence of free fatty acids (FFA). The then obtained neem oil is rich in specific gravity and viscosity, and with a lower calorific value range they cannot be directly blended with diesel or petrol as the flash point of neem is too low, this increases the emission and reduces the engine power and in long run clogs the engine. A similar fuel with chemical properties matching to neem is found to be plastic oil, besides considering the economical benefits plastic oil can be availed abundantly its calorific value is higher than that of diesel and plastic oil if blended with neem could be an alternate viable solution for the engine. [2]Fuel oil from plastic waste is a kind of heavy oil which has heating value greater than 10000 kcal/L. Waste plastic such as PE (polyethylene) PP (polypropylene) PS (polystyrene), etc. [3]has higher oil yield above 50%, which means from the above 10-ton waste plastic, you can extract at least 5-ton pyrolysis fuel oil, the plastic oil can be processed by pyrolysis through pyrolysis decomposition of long chain hydrocarbons molecules (polymer) into smaller sizes (monomer) using high temperature range from (450°C–800°C). both plastic and neem oils together give quality fuel properties similar to diesel, the low CV of neem can be tolerated with high CV of plastic oil, thus the blended fuel will have a compromised CV and other properties that is similar to diesel. The plastic oil and neem oil can be together blended in varying proportions to find the most promising
alternative fuels are taken with reference to the calorific value, specific gravity, cetane number etc. they are blended in the suitable proportion. Is that their properties correlate with each other for perfectly blending with diesel fuel, as per the international standards and with reference to various other parameters, fuels are selected, which are (Plastic oil, Neem oil and their 10% blends). They are considered in blend ratio of B20, (which is 20% blend and 80% diesel fuel), Plastic oil B20, Neem oil B20 and their blends forming Plastic-Neem oil blended with 80% diesel. The objective is to create a fuel alternative to diesel. The performance and emission characteristics were taken from a multi fuel engine model Kirloskar AV1 having 5hp power produced from this single cylinder, constant speed, naturally aspirated engine whose compression ratio is 17. And the emissions like NOx, CO, CO2, HC, NO2, Smoke etc. taken separately from AVL smoke meter C47 and Di gas analyzer. Since testing in an engine involves a lot of efforts, time and cost, CFD analysis on ANSYS Forte is tried. Modelling of a combustion chamber for a bowl-shaped profile is initiated. The fuel is added by understanding the chemical reactions and physical properties exhibited by the considered fuel through the chemkin fuel library, blend fuels mixture ratios are selected based on the mass fraction of the considered species and afore mentioned emission. Graphs validates the results to suggest for an alternative fuel.

1. INTRODUCTION Reaping fuels by crude oil extraction process is the phenomenon of past, the world is in the rally to quench the thirst of never-ending source of alternative fuel methods, though a lot of research advancements have led the way to and some are in the stage of developing alternative fuels, but faces difficulties from the initial phase of finding raw materials to the process where the fuels getting fully ready to be used in engines, polluting substances, mushy and toxic effluents, particular matter etc., contribute to the greenhouse gasses which is a cause of ozone layer depletion, melting of polar ice caps etc. Charging of electric vehicle batteries cannot be accomplished without the presence of strong sources, even storing of energy requires a lot of effort and
