Increasingly stricter emission standards for gasoline and diesel engines accelerated the exhaust aftertreatment industry to develop high efficiency catalysts with innovative substrates. Engineers face thermodynamic and thermal management challenges to achieve system emission, noise and back pressure targets at minimum costs.
This paper describes advanced substrate technology for exhaust after treatment systems for gasoline and diesel engines. The first part focuses on substrate technology solutions including high cell density substrates and advanced metallic substrates with structured and perforated foil material. This new substrate technology offers great potential to optimize the overall system efficiency through exhaust mixing within the catalyst at minimum back pressure.
Transient temperature condition and available packaging space will have remarkable impact on system design and catalyst performance for future advanced combustion engines and hybrid vehicles.
