    “国六”大考来了 汽车企业忙升级

    首页 > 汽车 > 正文

      从2001年算起,我国实施排放标准已经超过17年。平均下来,三年一次升级。2019年7月1日,最新的国六政策将在包括深圳、杭州等多个城市开始实施。应对国六排放这件事上,总能听到这样的抱怨:实现的技术难度大,挑战高,成本大幅增加,进而削弱竞争力。国六排放综合了欧洲和美国的排放标准,污染物限值与欧6相同,蒸发排放和OBD接近美国,综合而言已经是全球最严排放法规。之所以要实施这一严格的排放法规,一是打赢“蓝天保卫战”,汽油车“责无旁贷”;二是排放标准每次升级,都是以三年为节拍,十余年下来,汽车企业都已经养成这一“习惯”;三是单缸优化、小排量涡轮增压、三缸机等技术能进一步挖掘汽油机的潜力。
      “清醒”的汽车企业正在争分夺秒,围绕国六排放相机制定了最为激进的动力总成升级战略。根据机动车环保网发布的通告,截至2018年12月28日,共有57家企业、891个车型、772988辆车先后进行了国六环保信息公开。其中,国内生产企业44家、660个车型652562辆。别克、凯迪拉克、本田、丰田、大众等企业正在加速车型的升级。以别克为例,旗下国六车型已经覆盖GL6、英朗、阅朗、GL6、昂科威等系列。
      相比于中国车市每年约2900万辆的产销量,77万多辆的国六车型,2.6%占比仍比较低。必须承认,有部分车企在“装睡”,他们在“豪赌”“国六”排放会再一次延期。当一个人决意要作出装睡的举动,如何呼喊也不能让他“如梦初醒”。记者查阅了多个城市的国六执行时间表,都是以正式公告的形式进行发布,而不再是“征求意见稿”。换言之,国六排放势在必行。
      节能环保是社会主流诉求,汽车排放升级是大势所趋。坚持改进和完善传统动力,不仅是技术发展的必然,也是全行业的共识。不要对小排量涡轮增压、缸内直喷、三缸、发动机小型化等新技术有所担心。这些新技术投放之前,都经历了严苛的可靠性和耐久度测试,并在动力输出、性能表现、油门响应以及NVH上,最大限度接近用户的驾驶习惯。
      上汽通用汽车泛亚汽车技术中心发动机燃烧及架构技术总监王立新认为,根据整车实际的性能需求,选择合理的单缸排量并进行优化,传统内燃机在不牺牲性能的前提下,还能够满足国六排放要求。传统内燃机不怕“高标准”,就怕“没标准”。显然,在负责任的动力总成专家的工作计划里,都已经有适应更为严苛“国七”的备案,这一点都不夸张。按照三年一升级的节拍,“国七”排放并不遥远。
      经常有人找我谈驾驶三缸机的感受:三缸机宣传那么久,油耗似乎没有宣传的那么低。发动机从六缸机减少为四缸机的时候,一开始,人们也有这种困惑。事实是,油耗是有降低,只是人们的预期值太高。国六是不可逆的,技术是可逆的,前提是愿意付出。
