Analyzing the Emission Characteristics of a Catalytic Converter using a Nano-ZnO Coating

Abstract

Due to the ever-growing challenge of pollutants emitted by vehicles, protection of the environment from the pollutants has become a focus of attention. The rising volume of traffic on our nation's roadways now poses a severe danger to the environment due to hazardous emissions, and the refueling availability and low maintenance of petrol fuel vehicles have prompted many to choose for petrol vehicles. Numerous experts have used a variety of strategies to decrease the amount of emissions produced by vehicles, but this sector still has a great deal of room for advancement. The objective of this work is to compare the emission characteristics of a four-stroke petrol engine with and without a nano zinc oxide (nano-ZnO) encased catalytic converter. The findings indicated that the nano-ZnO coated catalytic converter aided in reducing the CO, CO2, HC and NOx emissions by 41.3%, 71.4%, 48.2%, and 46.7%, respectively © 2022 Published under licence by IOP Publishing Ltd.
