Diesel Emission Control I

This lecture covers the main pollutants emitted by internal combustion engines, such as CO, NOx, HC, and PM, along with European emission limits for Diesel cars. It explains how to test compliance with emission limits using engine test rigs and dynamic test cycles. The lecture also discusses the influence of cell density on catalyst activity, emission control technologies for Diesel engines, and the trade-off between NOx and PM emissions. Additionally, it explores the reduction processes for NOx in Diesel vehicles, the challenges faced by SCR catalysts, and the composition of V-based SCR catalysts.
