Applications

Vir2sense provides engine combustion and emission models and virtual sensors for various industrial applications, including:

  • Automotive/Heavy Duty:
    • provide predictive combustion and emission models for use in software (0-D/1-D) for engine design
    • provide specially developed combustion and emission models for fast engine simulations (0-D/SiL/HiL) and parameter tuning, including transient operation, in order to aid with the engine tuning for different applications/legislated limits. The models are provided already tuned for a specific engine type, and can be used for the off-line optimization of engine controllers, to satisfy stringent emission legislation in combination with highly variable operation of the engine (variable load, variable speed)
    • provide virtual combustion and emissions sensors for:
      • emission feedback control
      • satisfaction of not-to-exceed emission limits under variable engine operation
      • accurate control of emission after-treatment devices, based on real-time prediction of emissions
      • adaptation of controls for component aging and manufacturing inaccuracies/clearances
      • adaptation of controls for optimal engine and after-treatment operation when using different/alternative fuels
      • condition monitoring of engine components and physical sensors
  • Marine:
    • provide predictive combustion and emission models for use in software (0-D/1-D) for engine design
    • provide virtual combustion and emissions sensors for:
      • emission feedback control
      • adaptation of controls for component aging and manufacturing inaccuracies/clearances
      • adaptation of controls for optimal engine and after-treatment operation when using different/alternative fuels
      • condition monitoring of engine components and physical sensors
    • provide emission monitoring and reporting in conjunction with physical sensors in Continuous Emissions Monitoring Systems (CEMS), to increase sensor lifetime and plausibility in harsh exhaust environments. The combination of physical and virtual sensors for emission monitoring and reporting is dubbed Physically-assisted Virtual Sensors (PVS)
