In our past research, we highlighted the fact that the implementation of the Miller cycle comes with a drawback related to the decreasing of the intensity of the internal aerodynamics. This paper aims to highlight the impact of some constructive modifications done in order to improve the turbulence level inside the cylinder while operating in Miller cycle. More precisely, it is about the increasing of the piston stroke and the introduction of the masking at the intake valve level. The effect of these modifications is assessed through 3D CFD simulation based on the RANS approach.}}
