Topics
Alec Skolnik: 我是Liquid Piston的联合创始人兼首席执行官Alec Skolnik。我和我的父亲在2003年创立了这家公司,致力于研发革命性的发动机。我的背景是机器人和人工智能,而我的父亲是一位物理学家,他长期以来一直对热力学和能源解决方案感兴趣。我们对发动机的研究始于对热力学和优化的基本思考,例如如何提高发动机的效率。我们发现,传统的内燃机效率低下,仅能将15%-17%的燃料能量转化为机械能。这促使我们重新审视并创新Wankel旋转发动机设计,最终开发出X引擎。 X引擎是基于我们对高效率混合热力学循环的理解而设计的。这个循环结合了柴油机、奥托循环和阿特金森循环的优点,实现了高压缩比、恒定容积燃烧和过度膨胀。我们通过旋转式发动机设计来实现恒定容积燃烧,这使得燃料和空气的混合和燃烧过程更加充分。与传统的Wankel发动机相比,我们的X引擎设计将燃烧室置于外壳中,而不是转子中,这使得我们可以实现更高的压缩比,并支持直接燃油喷射。此外,我们还解决了Wankel发动机在密封和润滑方面的长期难题。 X引擎能够运行多种燃料,包括重型燃料(如煤油、喷气燃料和柴油)、汽油,甚至伏特加。未来,我们还计划使其能够运行氢燃料。这使得X引擎在军事和民用领域都具有广泛的应用前景。在军事领域,X引擎可以显著减轻发电机的重量和体积,提高其便携性和可靠性。在民用领域,X引擎可以应用于各种需要小型发动机的场合,例如辅助动力单元等。 我们已经为美国军方开发了10千瓦的X引擎发电机原型,并获得了3500万美元的空军合同,用于研发更大功率的发动机。我们正在努力将X引擎技术推向市场,并与其他公司合作,以实现大规模生产。虽然将X引擎应用于汽车领域可能还需要一段时间,但我们相信,X引擎技术将彻底改变能源领域,并为混合动力汽车提供一种高效的解决方案。 Christopher McFadden: (访谈主持人的问题和引导性发言,此处省略具体内容,因为要求不翻译参与者的名字,且核心论点需使用第一人称视角)
