Effects of Waste Plastic Oil Blends on a Multi Cylinder Spark Ignition Engine

Existing fossil fuels are utilizing at their critical rate, leads to depletion of their reserves in a dramatic way. Generating alternative energy sources in a pragmatic way are necessitated, which demands the researchers to utilize the inherent energy of carbon based products as an energy source to the automobile sector. As a part of it, my research is focused on transforming and using the waste plastics as an alternative fuel in multi cylinder spark ignition engine. This paper aims to present the experimental investigations of performance and emission characteristics in an existing Maruti 800 petrol engine running with the blends of 5%, 10%, 15% and 20% of waste Plastic Pyrolysis Oil (PPO) with gasoline. From the results, it is noticed that hydrocarbon emissions are substantially reduced and oxides of nitrogen emissions are increased and petrol engine can operate with PPO blends up to 20% without any engine modifications.
