Virtual Combustion and Emission Sensors

Vir2sense provides  combustion and emissions virtual sensors. Virtual sensors are ultra-fast models, which provide accurate combustion and emission values, calculated from engine actuator, engine state and environmental inputs.

Virtual sensors can be used to replace/assist physical sensors, for:

  • Engine torque feedback control
  • Engine emission feedback control
  • Engine online optimization for emission compliance and fuel consumption minimization
  • Engine after-treatment control
  • Physical sensor plausibility checks

The advantage of virtual sensors compared to physical sensors include:

  • Near-zero sensor response time (millisecond calculation time) – important for engine emission feedback and after-treatment control
  • Unlimited sensor reliability
  • Zero marginal sensor cost

Virtual sensors can be provided as pre-tuned sensors or as self-tuning sensors for online tuning based on a physical sensor input.
