Performance and emission analysis on gasoline engine fuelled with pyrolysis oil produced from waste plastic using rice husk ash as catalyst

ABSTRACT

The ultimate aim of this paper is to extract from plastic waste by pyrolysis using a novel catalyst of rice husk ash. The extracted WPO were tested and found to have properties identical to gasoline. The WPO is blended with commercial petrol in various ratios such as 10%, 20%, 30% and mentioned as WPO10, WPO20 and WPO30. The blends were tested in gasoline engines and the combustion efficiency and emission characteristics of these fuels are investigated and compared with regular commercial petrol. It is observed that the brake thermal efficiency is considerably low for all the WPO blends when compared to gasoline. The difference in Brake thermal efficiency of petrol and WPO10 is 0.77% which is almost closer to petrol and also emits CO of 0.09% by volume, NO_x of 625ppm and HC of 21 ppm at maximum load. It is concluded that WPO10 is suggested for the best overall results.
