Using these model, mechaners can:

  • Itify regions of pour mixing that lead to high emisions.
  • Optimize chamber shape - piston bowl, smish area, or pembakaran linar - to enced turbulence and flame propation.
  • Prediksi temperatur gradients thatt cause thermal stress and retigue.
  • Analisa pembakaran tidak stabil dan tidak beraturan-premium pembakaran and pengembangan dampers or geometric modifictions.
