In this paper, a CFD analysis

was carried out to study the

scavenging process of a two

stroke engine. Particularly, an

Otto, 125cc, single-cylinder,

loop scavenging and direct

injection engine was studied.

Transient solutions of pressure,

velocity and mass fraction

fi eld have been obtained

numerically.

In order to validate this model,

the numerically obtained

results were compared to

experimental obtained ones,

which means that this work

can perfectly simulate what

happens inside the cylinder. In

future projects, the aim is to

use this model to optimize the

effi ciency of the new engines,

reducing the habitual problems

of short circuiting and losses of

fresh charge
