  • Chinese Utility Model Patent No. CN204113400U discloses an exhaust aftertreatment device including an intake manifold assembly and a post-processing carrier downstream of the intake manifold assembly, wherein the intake manifold assembly includes a cartridge Body and intake pipe. This design makes the length of the intake pipe assembly large and the application range is greatly limited.
  • the uniformity of ammonia distribution in the exhaust aftertreatment system has an important impact on the overall performance and durability of the system. If the distribution of ammonia (NH 3 ) is uneven, the nitrogen oxide (NOx) conversion efficiency is too low, and if the urea injection amount is increased in order to satisfy the discharge performance, ammonia leakage contamination is likely to occur. At the same time, the urea droplets are easily deposited when they are exposed to a wall surface having a relatively low temperature, and when the crystal is severely formed, the exhaust pipe is blocked, resulting in a decrease in engine power performance. Increasing the mixing uniformity of ammonia molecules can effectively improve the urea utilization rate and reduce the urea injection amount, thereby reducing the risk of urea crystallization.
