Project Name: CFD analysis of Volcano air intake manifold.

Objectives: To perform steady state CFD analysis for the intake manifold

of Volcano engine with EGR mixer in order to predict:

. Cylinder to cylinder %EGR mass fraction variation from mean.

. Cylinder to cylinder charge flow (mixture of air and EGR).

. Pressure drop across air and EGR path for each cylinder.

Results:

. Cylinder EGR variation from mean was predicted to be 10% which is

within acceptable limits.

. Analysis was documented and presented to manager.

Future recommendation:

. Reduction in multiple cross section changes will result in lower EGR

path pressure loss coefficient

. To get sufficient air-EGR mixing length, EGR tube can be moved back

at its inlet.
