Automotive emissions control

Local and global environmental concerns regarding automotive emissions motivate legislative action by governments throughout the world. Aggressive regulation of both tailpipe and evaporative emissions of passenger vehicles is the norm in most developed countries. These governmental regulations produce significant challenges and opportunities for control, particularly when combined with other system objectives such as fuel economy and performance. This tutorial presents an overview of the challenges related to emission control in the design and development of powertrain systems for modern passenger vehicles.
