ESEMISSION ANALYSIS OF SINGLE CYLINDER DIESEL ENGINE FUELED WITH PYROLYSIS OIL DIESEL AND ITS BLEND WITH ETHANOL

摘要

Around the world, initiatives are being taken to replace gasoline and diesel fuel due to the impact of the fossil fuel crisis, increase in oil price, and the adoption of stringent emission norms. Increase in energy demand, stringent emission norms and depletion of oil resources led the researchers to find alternative fuels for internal combustion engines. Many alternate fuels like Alcohols, Biodiesel, methanol, ethanol, LPG, CNG etc have been already commercialized in the transport sector. In this context, pyrolysis of solid waste is currently receiving renewed interest. Tests have been carried out to evaluate the emission analysis of a single cylinder direct injection diesel engine fueled with 10%, 15%, and 20% of tyre pyrolysis oil (TPO) blended with diesel fuel (DF). The TPO was derived from waste automobile tires through vacuum pyrolysis. HC and CO emissions were found to be higher at all loads due to the high aromatic content. Ethanol was added in concentration of 5%, 10% and 15% to reduce emission characteristics. Results show that CO and HC both reduced due to the addition of ethanol because ethanol is an oxygenated additives.
