Computational Fluid Dynamics:
3D CFD analysis has become the need of the hour since; every stage of the design has to be validated.

Combustion & Spray Optimization:
Intake and Exhaust Systems
This simulation task is dedicated to optimize the intake air path from the air inlet to engine intake ports in terms of pressure losses. Particular attention is paid to:
  Optimization of the geometry in respect to the pressure drop   Flow distribution investigation in the port and manifold
  Investigation of the air delivery to each cylinder   Reduction of recirculation and stagnation of air
  Tuning of ports for the required target
