EGR waste gas mixed organization

The utility model discloses a EGR waste gas mixed organization, include: pipeline, impeller, impeller shaft and impeller support, the one end of pipeline is connected with engine air intake manifold, and the other end is connected with the EGR system, impeller, impeller shaft and impeller support all set up inside the pipeline, and the impeller is two at least, and the rotation in the opposite direction of adjacent impeller, the impeller all cup joints on the impeller shaft, the impeller support is two, its and the axis of pipeline perpendicular setting the mutually, and the one end of impeller support is connected with the inner wall of pipeline, and the other end is connected with the impeller shaft. This kind of EGR waste gas mixed organization improves optimization through the structure to the pipeline, and at the inside impeller that sets up a plurality of mutual reverse rotation that increases of pipeline, EGR waste gas and fresh air can utilize a plurality of reverse rotation's impeller to produce the strong vortex through " windmill " principle to make the mist can carry out abundant integration in the pipeline, effectively improve the mixing uniformity of mist.
