Compression Ignition Applications

The SRM Engine Suite combustion software contains advanced combustion models specifically for application to Compression Ignition (CI) engine combustion. These models can be used to investigate direction injection, the ignition process/auto-ignition, non-premixed turbulent combustion and in-cylinder emissions including soot formation.

Major Benefits

  • Multiple direct injection events, including pilot injection and rate profiles
  • Impact of injection pressure on combustion characteristics and exhaust gas emissions
  • Predictive simulations combining both the ignition and non-premixed combustion regimes
  • 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 model. e.g. conventional (diesel and gasoline) as well as alternative (natural gas, ethanol, biodiesel) fuels
  • Integrated detailed soot model: Detailed population balance soot (PBS) model enables calculation of soot morphology, composition and detailed particle size distribution
  • Thermal Analysis – Predictions of exhaust gas temperatures
