Numbers of patents emerged in the automotive exhaust industry, technology and market in a new situation

Recently, the automotive exhaust industry presents a series of compelling new developments, a number of companies make breakthroughs in the technology research and development, get relevant patents.They inject new momentum for the development of the industry , while the market also shows a unique development trend.

According to the information of State Intellectual Property Office, on May 2, 2025, Armor Man Co., Ltd. successfully obtained a patent titled ‘Exhaust Pipe Device’, with the authorisation announcement number CN116162919B, and the date of application can be traced back to July 2022, which is the first time for Armor Man Co. to obtain a patent in this field. Ltd. has been deeply cultivating in the field of R&D and production of auto parts for many years. This patent is related to the design of a new type of exhaust pipe, which can effectively reduce the harmful gas emission in the process of automobile driving by optimising the flow path of the exhaust and reducing the resistance of the exhaust. The innovations include the hydrodynamic optimisation of the exhaust pipe geometry to reduce the exhaust vortex and improve efficiency; the use of a new type of high-temperature-resistant material to ensure stability and prolong the service life in high-temperature environments; and the design of the product takes environmental protection factors into account to minimise the impact on the environment.

Also on May 2, Yuchai United Power Co., Ltd. obtained a patent for ‘A Methanol Engine Exhaust Pipe’, authorised under No. CN222797566U, which is installed in the engine, and can conveniently detect the methanol combustion efficiency of the engine through the oxygen concentration and pressure sensors on the pipe, thus greatly enhancing its utility. On May 5, Jilin Huayu Auto Parts Co., Ltd. obtained the patent of ‘A kind of heat insulation cotton packing device for automobile exhaust pipe’ (Authorised Publication No. CN222808355U). The device can achieve the clamping and fixing of Exhaust Pipes of different diameters and lengths by rotating the rotary block, hand-twisting the block and other parts, and can also efficiently and uniformly wrap and pack the heat-insulating cotton of the exhaust pipe through the cooperation of the motor and the electric telescopic rod, so as to improve the packing efficiency and effect.

From the market level, the automotive exhaust pipe industry is also continuing to develop and evolve. According to a QYResearch report, the global automotive exhaust pipe reel market size was approximately USD 150 million in 2024 and is expected to climb to USD 191 million by 2031, growing at a compound annual growth rate (CAGR) of 3.6% during 2025-2031. Automotive exhaust reels play an important role in protecting workers from toxic gases as a mechanical system used in vehicle workshops to safely remove harmful exhaust gases from vehicle exhausts and vent them outside the building.

Automotive exhaust industry in the promotion of technological innovation, is towards a more environmentally friendly, efficient and practical direction, the future with the transformation and application of the results of the patent and the further release of market demand, the industry is expected to usher in more changes and opportunities.
