SimCat
SimCat is a simulation tool used for modeling diesel engine exhaust after-treatment systems including the exhaust gas recirculation (EGR), diesel oxidation catalyst (DOC), selective catalytic reduction (SCR), ammonia oxidation (AMOX) and associated urea and fuel injection systems.
The need for simulation
Simulation allows for the design of these systems without the need to use actual physical models.
The benefits of this approach are many, including quick design investigation turn-around, potential for increased design robustness studies and virtual system configuration tests.
SimCat solutions are suitable for implementation directly on an ECU.
In a competitive and demanding diesel exhaust treatment environment SimCat enables designers to ensure compliance with tough exhaust standards such as EURO VI, US2010 and Japanese emission limits in the most time-efficient way possible.
Common application areas
Current customers are using SimCat for the following applications:
- Euro IV and V test-bench - reliably execute engine cycles in a virtual environment
- Closed-loop combustion control engine with real-time control
- DPF soot load predictors based on pressure drop and a regeneration strategy
- Full engine and SCR calibration
- Calibration and certification of Euro III common rail diesel engines
- Transient cycle test-bench: WHTC, ETC, FTP, JE05
- Cold-start impact
