Passenger car exhaust system
Passenger car products cover the whole set of exhaust system (purifier-hot end, muffler-cold end, active valve), which can meet the National VI and above emission standards. They are suitable for natural inspiratory type, turbocharged type, hybrid type and other power systems. The active valve can also meet the young generation for sound requirements.
Double out muffler
As the main muffler module in the exhaust system, the product adopts impedance compound muffler structure, and has the muffler composed of resistant muffler unit and sound absorbing material combination. It has the common characteristics of resistant and resistant muffler, and has good muffler effect on low, medium and high frequency noise.

Manifold type converter
Manifold converter is a catalytic purification device connected to the engine cylinder block and the exhaust of each cylinder is concentrated using divergent pipelines.

TWC+GPF tight coupling converter
This structure coupling the original bottom plate type converter with the pre-catalyst has three characteristics: on the one hand, it ensures the ignition temperature of the rear stage carrier and improves the conversion efficiency of the carrier; on the other hand, it greatly reduces the use of heat shield on the pipeline and reduces the cost; finally, because the carrier is tightly coupled into the engine room, the chassis space is released to a large extent. At present, this structure is the mainstream structure of China Six passenger car products

DOC+SDPF tight coupling converter
DOC+SDPF tightly coupled type is mainly applied to the rear processor layout of light diesel vehicles. This platform is suitable for the model displacement of 2.0-3.0L. Since the post-processing is installed in the engine compartment, the layout space is compact, and the mixing distance is short compared with that of conventional medium and heavy diesel vehicles, the mixer design is difficult.

Bottom plate converter
This structure is the typical structure of the National VI B1 stage light wood bottom plate converter, encapsulating the internal SCR carrier front-end integrated mixer, ammonia mixing efficiency can reach more than 99%. The main feature of this structure is the packaging front-end integrated bellows, the whole and chassis are mounted by the hook mounted rubber lug, the whole connection achieves flexible fixing. The reliability and durability of the whole structure can be improved at the same time.
