Real-time simulation of a complete diesel exhaust aftertreatment system.
The ASM Diesel Exhaust System Model is an extension to ASM Diesel Engine and ASM Diesel Engine InCylinder and provides variable configurations of diesel exhaust aftertreatment systems, supporting a DOC, a DPF and an SCR system.
The various exhaust model components can be combined to match the aftertreatment system being tested, which ensures that it complies with the desired fuel consumption and emission standards.
The ASM Diesel Exhaust System Model mainly consists of a DOC, a DPF, and an SCR system. It covers typical sensor variables for ECUs in DOC and DPF applications, such as temperatures, pressures and lambda values. These applications investigate effects of soot trapped by filtering material and of DPF regeneration. The oxidation of post-injections and of fuel introduced by catalytic burners is also included in the model. With its solution for simulating common AdBlue and diesel exhaust fluid (DEF) dosing systems with and without air supply and its modeling concept for evaluating the urea decomposition and chemical process of the catalytic reduction, the ASM Diesel Exhaust System Model can be used as a basis for modeling today’s aftertreatment systems.
