    6. Cylinder pressure prediction
    7. Knock prediction

2. Positive Crankcase Ventilation – 1D Blow-by-simulation

  1. The key objective of this technique is to vent out the Blow by gases ( constituting unburnt gas and oil vapors ) so as to not compromise on the adverse effect of pumping losses over the engine efficiency

  2. DEP ensures broad application of 3D – 1D integrated modelling & simulation to analyze the Crankcase pressure inside the engine & the blow by production as a function of speed & load via PCV valve

  3. The simulation focusses on performance optimization of PCV system by accurately matching the ventilation flow with blow by production characteristics while engine performance and drivability remain unaffected.
