The Engine Silent Star
On December 21, the first certification conference of "CAC-PV18-114:2023 CATARC Mark Certification Implementation Rules - Engine Silent Star" was held in Wuxi, Jiangsu. The "Engine Silence Star" CATARC mark certification is jointly launched by the Engineering Institute of China Automobile Center and China Automobile Center Huacheng Certification, which is the authoritative engine silence performance certification in the industry. The launch event was hosted by China Automotive Technology Research Center Co., LTD., and was jointly supported by more than 50 media outlets such as China Automotive News and Pacific Automotive Network.

At the press conference, Zheng Yong, deputy chief engineer of Huacheng Certification, gave a speech for the press conference, he said that under the background of the development of new energy vehicles, the power product market is also constantly innovating, plug-in hybrid, extendate-range hybrid and other configurations of hybrid vehicles are in full force, increasingly becoming the main market models. Whether conventional power or hybrid power, the engine is the main contributor to the noise of the powertrain. The quiet performance of the engine is a key factor in determining the sound quality and comfort of the vehicle, and has a decisive impact on the driving experience and comfort of the vehicle driver and passenger. The general engine silence performance evaluation method with a high degree of subjective perception is very necessary, so the Zhongqi Center Huacheng certification launched the "engine silence star" CATARC mark certification, certification rules are based on the massive engine database accumulated by the engineering institute of Zhongqi Center for many years, through statistical analysis and theoretical research to obtain a variety of engine noise level guidance value and so on The level limit is used to determine the level of engine silence. It can not only guide enterprises to improve product performance, but also provide reference for consumers to understand products and compare purchases.
