摘要: An exhaust gas system for an internal combustion engine includes a first treatment unit with back pressure and second being higher than the pressure. The advantageously enables configuration of systems having two units that are disposed one behind other in flow direction. and/or can have smaller construction due to homogenization flow. This applies, example, when oxidation-type catalytic converter is provided as particulate filter unit. increases conversion rate so be construction. saves considerable costs configuring such systems.
