Abstract
With the continuous growth of motor vehicle ownership, exhaust emission has become one of the main sources of urban air pollution, posing a serious threat to environmental quality and human health. To meet this challenge, this study focuses on the latest progress in vehicle emission control technology and their environmental impact, with the aim of systematically combing the existing technology systems and evaluating their emission reduction effects. Through the extensive investigation of relevant literature at home and abroad and the practical application case analysis of typical control technology, the research found that the current mainstream technologies including ternary catalytic converter, particle trap, selective catalytic reduction system, etc., have achieved remarkable results in reducing the emissions of carbon monoxide, nitrogen oxide and particulate matter. In particular, the application of new catalyst materials not only improves the pollutant conversion efficiency, but also extends the service life of the equipment. In addition, the intelligent emission control system realizes more accurate emission management through real-time monitoring and feedback regulation.
