Abstract

The increasing population density of automobiles leads to demands more fuel consumption that leads to reducing the availability and also raises the cost. Therefore, it is necessary to search for an alternate fuel, which can effectively replace the conventional fuel without affecting the engine design. The objective of this paper is to discuss the influence of waste plastic oil blends from 0% to 25% at four different ratios fuelled in a multi-cylinder Maruti 800 SI engine by using two types of sparkplugs; the conventional type spark plug that consists of a centre electrode with a copper core, and a plug with an iridium based electrode tip. From the outcomes of the experiments, the engine efficiency is improved, and emissions are controlled by using iridium spark plugs compared to the conventional type spark plugs. At a higher blend of 25%, PPO performance and emissions are analysed and presented in this research. The oxides of nitrogen emissions of engine fuelled with 25% of the plastic oil blend are 13% reduced, and 4.5% brake thermal efficiency are enhanced by using iridium spark plugs compared to 25% of plastic oil by using the conventional type of spark plugs at full load conditions.
