Investigation of After Treatment Techniques to Mitigate the Emissions from IC Engines

Abstract

Diesel engines require innovative technologies to decrease pollutants and newlinefuel costs. Since the turn of the century, researchers have concentrated their efforts on newlinelowering emissions from automotive engines, boosting vehicle efficiency, and reducing newlinethe quantity of gasoline required by automobiles in order to assist developing countries newlinein meeting their challenges. Chemical recycling converts discarded plastics into plastic newlineoil. In this procedure, plastic oil is used instead of diesel. The performance and emission newlinecharacteristics of engines powered by plastic oil blends are investigated. Much hinges newlineon the economic viability of creating plastic oil as a replacement for petroleum-based newlineCompression Ignition engine (CI) engine fuels. Pyrolysis plants have low total costs due newlineto a mix of capital investment and operating expenses. This has spurred the increasing newlinedevelopment of after treatment systems to reduce the Nitrogen oxide (NO) and newlinehydrocarbon (HC), Carbon monoxide (CO) and smoke emissions. newlineThe three main after-treatment methods studied in this work are Scrubbers, newlineCatalytic Convertor (CC), and Selective Catalytic Reduction (SCR). A four-stroke, newlinesingle-cylinder, computerized, water-cooled, diesel engine with all three aftertreatment newlinemethods was used to evaluate Diesel Plastic Blend (DPB) performance and emissions. newlineTesting is conducted at different loading levels minimum to maximum load condition. newlineNO and HC are highly poisonous chemicals released by automobile sector. newlineEmissions are controlled most commonly by scrubbers in power plants and marine newlineengines. Wet scrubbers are used as the initial after-treatment procedure to minimise newlinepollutants. In this study, Potassium Permanganate (KMnO4), Sodium Bicarbonate newline(NaHCO3), Sodium Chloride (NaCl), and Sodium Hydroxide (NaOH) are used as newlinesuitable chemical solutions in the scrubber for reducing NO, HC, CO, and Diesel newlineengines fueled by a plastic-diesel blend at 50 % each release smoke newline
