- injection ports are circular in shape but could very well be rectangular or any other shape, such as for example a slot.
- the orifices of the same pair may be identical.
- the diameters D1, D2, D3, D4 respectively of orifices 26.1, 26.2, 26.3, 26.4 may be between 8 and 20 mm. They may be, for example, decreasing from the inlet 21 of the channel 24. As for the injection channel, it may be, for example, of frustoconical shape with a section of, for example, between 20 to 28 mm.

- the distances d1 .1 + d2.1, d1 .2 + d2.2, d1 .3 + d2.3, d1 .4 + d2.4 between the opening 22 and the yoke 32 may be between, for example, 47 and 69 mm, thus avoiding the return of flame from the cylinders to the heat exchanger 16. They are increasing from one orifice to another from the input 21 of the channel 24 in the case of an intake module biased towards the cylinder head.
- 26.2, 26.3, 26.4 may be perpendicular to the direction of flow, or flow, of the intake gas from the heat exchanger 16 and towards the cylinder head 32.
- the direction of injection of escapement recirculated through the orifices 26.1, 26.2, 26.3, 26.4 may form an angle, with the direction of flow of the intake gas from the heat exchanger 16 and towards the cylinder head 32, between 0 and 80 degrees.
- the orientation of the recirculated exhaust gas towards the cylinder head 32 makes it possible in particular to reduce the fouling of the injection channel 24 by the recirculated exhaust gas which is directed more directly and rapidly towards the cylinder head 32.
- the injection orifices are located, for example, in the half of the central zone of the distribution box 18 located on the heat exchanger 16 side.
- the direction of injection of exhaust gas recirculated through the orifices 26.1, 26.2, 26.3, 26.4 may form an angle, with the flow direction of the intake gas from the heat exchanger 16 and heading towards the cylinder head 32, between 100 and 180 degrees.
- the injection orifices are thus configured so that the injection of the recirculated exhaust gas is directed towards the heat exchanger 16.
- This orientation of the recirculated exhaust gas towards the heat exchanger 16 makes it possible, in particular, to in the distribution box 18, the recirculated exhaust gases injected with the cooled air coming from the heat exchanger 16 are better mixed.
- the injection orifices are located, for example, in the half of the central zone of the distribution box 18 located on the side of the cylinder head 32.
- some of the orifices of the same injection channel 24 can be oriented so that an angle is formed, that is to say with an injection direction oriented towards the cylinder head, and other ports of the same injection channel 24 may be oriented so that the direction of injection is perpendicular, or oppositely oriented with respect to the flow direction of the intake gases from the heat exchanger 16 and pointing towards breech 32.
