srm suite – SI mode |
| The srm suite combustion software contains advanced combustion models specifically for the application to Spark Ignition (SI) engine combustion. These models can be used to study direct injection, SI turbulent flame propagation, cycle-to-cycle variations, in-cylinder emissions and autoignition chemistry leading to engine knock. |
| |
| “The srm suite resolves the progress of the chemistry for each region of the chamber from mixture preparation, through the flame front and during expansion leading to improved predictions of all major exhaust emissions” |

| Major benefits |
-
Predictive pre-mixed turbulent flame propagation and fully coupled end gas autoignition. The rate of autoignition can be used to formally determine knock intensity.
- Cycle-to-cycle variation simulations
- Multiple injection including during negative valve overlap
- Crank angle resolved combustion characteristics (heat release rate, combustion phasing and duration, and in-cylinder pressure)
- Crank angle resolved evolution of chemical species including intermediates (OH, formaldehyde) and all emissions (CO, HC, NOx and soot)
- Capable of simulating user-provided fuel models. e.g. conventional (diesel and gasoline) as well as alternative (natural gas, ethanol, biodiesel) fuels
- Integrated detailed soot model: Detailed population balance soot model enables calculation of soot morphology, composition and detailed particle size distribution
- Thermal Analysis – Predictions of exhaust gas temperatures
