Tyre Pyrolysis Oil as an Alternate Fuel for Diesel Engines

Intensified search for alternative fuels is the main interest across the world due to the impact of fossil fuel crisis, ever increasing vehicle population and oil price and stringent emission norms. On the other hand, the disposal of waste tyres from automotive vehicles becomes complex. Apart from alternative biomass derived fuels like Ethanol, Methanol, Hydrogen, Vegetable oils etc, the new sources for alternative fuels are also appreciable. In this context, Pyrolysis of solid wastes is currently receiving renewed interest. The disposal of waste tyres can be simplified to some extent by Pyrolysis. In this paper, the properties of the pyrolysis oil derived from the waste automobile tyres were analysed and compared with the petroleum products and pure rubber pyrolysis oil. Also, Tyre pyrolysis oil-Diesel blends were used as alternate fuel in a four stroke Diesel Engine without any modification in the engine and the performance and emission characteristics have been studied. The tyre pyrolysis oil seems to be a promising alternative fuel for diesel engines if the production process of Pyrolysis oil is simplified.
