Research on the Hazards and Emission Control Strategies of Small Agricultural Gasoline Engine Exhaust

Abstract

With the widespread use of small gasoline engines in lawnmowers, generators, and chainsaws, their exhaust emissions have become a significant environmental pollution issue. Small gasoline engine exhaust primarily contains carbon monoxide (CO), nitrogen oxides (NOx), and hydrocarbons (HC), which negatively impact air quality and pose threats to human health. To mitigate these emissions, research on emission control strategies for small agricultural gasoline engines is increasingly important. This study aims to explore and evaluate different exhaust treatment technologies for small gasoline engines, including traditional catalytic converters, emerging particulate filters, electric catalysts, and selective catalytic reduction (SCR) technology. The study highlights the importance of these exhaust treatment technologies in reducing environmental pollution and promoting sustainable development, contributing significantly to environmental protection and the sustainable development of the ecological environment.
