Evaluation of various wet scrubbing solutions for CI engine exhaust

Abstract

Automotive sector emissions, including nitrogen oxide (NO), Carbon monoxide (CO), and hydrocarbons (HC), are extremely hazardous. For environmental regulations, the scrubber technique is commonly used in naval application. In this investigation, a Diesel Plastic Oil Blend (DPB) is used to minimize the emissions. Sodium hydroxide (NaOH), Sodium bicarbonate (NaHCO3), Lime soda (NaCl), and potassium permanganate (KMnO4) solutions were used to reduce the amount of pollution. The evaluation was done using a computerized, water-cooled, 4-stroke, Mono-cylinder, 5.2 kW diesel engine with a scrubber to ascertain its emission and performance characteristics. The experiments were conducted under several loading conditions. The NaOH, KMnO4, and NaHCO3solutions were found to reduce the NO emission. The NaOH and KMnO4solution minimized the HC emission. Additionally, the NaHCO3solution minimized the smoke emission, and the NaCl solution reduced the CO and CO2emissions effectively.
