Low Back Pressure Metallic Substrates Technology for CI Engines Used in Vehicles and Machinery to Meet Future Emission Requirements

The future demand for more fuel efficient and cleaner vehicles and machinery is a huge engineering challenge. On one side, regulated particulate matter reduction and gaseous exhaust emissions are addressed by higher EGR rates and optimized combustion technology. On the other side, after treatment components are added. Very compact systems are required and pressure drop need to be engineered to a minimum to minimize negative effects on fuel consumption. This paper describes the usage of thermodynamically optimized advanced metallic substrates components to address packaging at minimum exhaust flow resistance. The newly developed metallic cost-effective substrates with structured foil technology are engineered for lowest flow restriction and highest effectiveness.
