“rosjalap sikix kino”我国功率最rosjalap sikix kino大氢气发动机在辽宁大连发布

  中新rosjalap sikix kino网大连12月5日电(记者 杨毅rosjalap sikix kino)一汽解放6DV超级工厂投产暨首款氢气发动机发布仪式5日在辽宁大连举行。全新发布的首款CA6HV3氢气发动机最大功率可达460马力,是当前国内功率最大的氢气发动机。

  CA6HV3氢气发动机是一汽解放汽车有限公司(以下简称“一汽解放”)自主研发的、国内首款重型商用车缸内直喷氢气发动机,其最大能够爆发460马力,峰值扭矩2100牛米,90%纯度的灰氢就能高效燃烧,可实现零碳排放。

  一汽解放动力总成开发部产品设计三部部长苏欣在接受记者采访时说,氢燃料电池对氢气的纯度要求非常高,需要达到99.99%。而这款CA6HV3氢气发动机对氢气纯度适应性非常强,只需使用灰氢,氢气纯度达到90%以上就能产生比较好的燃烧效果,对制氢要求较低,因此可降低其使用成本。

  与天然气和柴油不同,氢可能进入到金属内部并影响金属内部结构,引起管道材料强度下降而发生脆性断裂,即所谓“氢脆”现象。苏欣表示,为突破这一技术难题,该款发动机与氢气接触的相关零件采用抗氢脆耐磨材料和特殊涂层技术,防止氢气分子扩散金属里,产生“氢脆”现象,进而达到保证发动机的可靠性和安全性。

  目前,该款发动机已装车一汽解放J6V牵引车,并在多家用户进行了应用验证,其最长里程已超2万公里,下一步将根据用户使用体验对技术层面进行逐步优化。

  当日,一汽解放6DV超级工厂正式投产。一汽解放6DV超级工厂自2022年7月启动建设,总投资6.2亿元人民币,这座超级工厂具备年产5万台发动机的产能。

  一汽解放动力总成事业部副总经理刘鹏表示,后续,一汽解放将加速工厂升级,全面满足15L天然气发动机、15L氢气发动机、14.5L柴油机、5-7L新中型发动机的生产需求。(完)
