新版《车用压缩天然气》强制性国家标准发布_我的网站

A |     　　讯 近日，市场监管总局（国家标准委）批准发布《车用压缩天然气》（GB 18047—2026）强制性国家标准，将自2027年8月1日起实施。    (ECNS) -- For Vitaly, a Chinese language teacher at Russia’s Higher School of Economics, textbooks tell only part of the story.    Born in 2002, Vitaly has found a creative way to engage his students with the language: AI-generated short dramas and Chinese pop culture.        “I watch Chinese AI short dramas to improve my own language skills, and I bring that same creative approach into the classroom,” Vitaly said.    By drawing on the fast-paced and engaging format of short videos, he helps students understand grammar and vocabulary in a more accessible and memorable way.    This summer, Vitaly led more than 80 Russian translation students to Changchun, Jilin Province, for a month-long study program at Jilin International Studies University.    Beyond the classroom, he encourages students to immerse themselves in contemporary Chinese youth culture, from collecting popular blind boxes to sampling local food at night markets.    Fluent in Chinese and familiar with everything from idioms and classical prose to the latest internet slang and memes, Vitaly believes that experiencing China firsthand is one of the best ways to understand the country.     By combining classroom learning with digital trends and everyday cultural experiences, he hopes to inspire a new generation of translators and help strengthen cultural exchanges between China and Russia.    (By Helen Mo, intern Lin Qiaochu)                    。　　本次标准修订旨在提升产品质量、保障使用安全、促进贸易公平。一是技术指标持续健全，新增甲烷值和互换性要求，明确车用压缩天然气的甲烷值应不小于65，与欧洲标准的要求保持一致，当甲烷值小于70时，加气站须在经营场所显著位置向社会公示具体数值。同一地区的车用压缩天然气应能互换使用，确保不同气源的天然气在切换使用时不影响发动机性能和安全性。二是试验方法全面升级，新增或调整了高位发热量、总硫、硫化氢、二氧化碳、氧气、水露点、水含量等项目的检测方法，其中甲烷值计算方法新增丙烷爆震指数法（PKI-MN法）作为仲裁试验方法，与国际标准接轨。三是取样与判定规则不断完善，新增“取样”独立章节，取样点设在车用压缩天然气交接点。判定规则明确检验结果达到全部质量要求视为合格，不符合时应复测。
