The device is intended to introduce additional gas flows (air, exhaust gas, cracked gas) in the intake channel (39) of an internal combustion engine (11) wherein the mixture is compressed by means of slots (9, 10) facing each other in the wall of the intake channel downstream of the throttle valve (2) and extended in the peripheral direction of the intake channel (39) on a peripheral angle smaller than 180<o>, to which the additional gas is supplied by one of a plurality of inlet conduits (6, 7, 8, 14, 15, 19, 20); regulation member (5) is provided to regulate the additional gas flow supplied by those inlet conduits as a function of the vacuum prevailing in the intake channel (39). The slots (9, 10) are orientated so that none of them is traversed by a partition surface separating the intake channel (39) and formed by the displacement of the longitudinal axis of the throttle shaft (21) in parallel to the very surface along the longitudinal medial line of the intake channel (39). Such a device provides for a good preparation of the mixture and consequently an enhancement of the thermal efficiency of the internal combustion engine while enabling to lower the fuel consumption and the noxious gas content in the exhaust gas. |
