Description

一种基于反应活性调控的氨氢融合燃料控制系统
技术领域
本发明属于内燃机技术领域，具体涉及一种基于反应活性调控的氨氢融合燃料控制系统。
背景技术
随着传统能源需求的持续上升和全球变暖问题的突显，世界主要汽车生产国纷纷加快部署，将发展清洁能源汽车作为国家战略，发展无碳燃料成为降低碳排放的重要解决方案。大时代背景驱使着传统内燃机向高效清洁燃烧的技术路线发展。近几年，内燃机技术的不断成熟，热效率不断攀升。然而内燃机的碳排放和污染物排放的根源在于燃料本身元素组成。因此，内燃机燃料的低碳、碳中性和零碳化将是内燃机的未来之路。
内燃机零碳技术的本质是燃烧碳中和燃料实现全生命周期的零碳排放。氢能由于良好的燃烧性能、近零的污染物排放以及可由可再生能源生产的性质而备受关注，发展氢能产业是实施“双碳”战略的重要抓手，然而氢气储运难和安全性差等问题制约了其产业化发展。研究发现，氨作为高效储氢介质，具有高能量密度、易液化储运、安全性高和无碳排放等优势，可以用可再生能源生产氢，再将氢转换为氨，运输到目的地，可以极大降低氢的运输成本，并且提高运输的安全性能。氨既是氢能载体，又是零碳燃料，对一定体积的液氨，其含氢量和能量密度分别为相同体积液态氢的1.7和1.5倍。此外，氨还可以通过可再生能源太阳能、电能等利用空气和水合成，整个制备过程无碳排放。我国幅员辽阔，有着十分丰富的太阳能资源、风能等可再生能源。良好的工业生产基础有利于逐步实现化石能源向可再生氨能源的转型。目前国内已有多家科研单位以及企业开始谋划布局氢氨产业链，国内福建、宁夏等地以及国家能源集团纷纷成立相关联盟组织研讨会，抢占先机。因此，发展氨氢融合燃料动力切合我国能源格局现状以及未来的战略调整。
氨气作为发动机燃料开发工作面临的主要挑战来自于氨的不良燃烧特性，如高自燃温度、低火焰速度及高的汽化潜热，较差的自燃能力和燃烧稳定性导致其作为发动机燃料时需要高反应活性的点火源引燃。着火和燃烧不稳定直接导致发动机动力性能和排放性能变差，并造成氨泄漏。而氨气具有腐蚀性和弱毒性，一旦泄漏，将腐蚀损伤发动机零部件、危及人员安全。因此，缸内稳定的着火与火焰传播过程对发动机燃烧过程优化、排放控制、安全性保障均具有重要意义。如何实现氨燃料稳定着火及高效燃烧是目前氨燃料发动机研制面临的关键技术之一。由于氨容易制备氢气，而氢气的燃烧速度快(3m/s)，通过车载制氢与氨气形成氢氨融合燃料，根据发动机负荷和转速的变化，实时调控燃料比例，可实现高效清洁燃烧。因此，车载氨裂解制氢技术和氨氢燃料混合比控制技术是氨燃料重型内燃机性能的关键技术。
发明内容

具体实施方式
为使本发明实施例的目的、技术方案、有益效果及显著进步更加清楚，下面结合本发明实例中所提供的附图，对本发明实施例中的技术方案进行清楚、完整的描述，显然，所有描述的这些实施例仅是本发明的部分实施例，而不是全部的实施例；基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明提出的一种基于反应活性调控的氨氢融合燃料控制系统，通过在进气道喷射氨燃料和氢气，在气缸内形成氨氢融合燃料，并通过控制氢气喷射量来调控氨氢融合燃料的反应活性。所述装置所需的氢气来源于车载制氢装置，由氨燃料制备。同时，所制备的氢气可供给预燃室，作为预燃室燃料，配合湍流射流点火装置，形成射流火焰点燃主燃烧室混合气，实现发动机点火性能提升。下面结合附图对该装置的工作过程作进一步说明。
如图1所示，一种基于反应活性调控的氨氢融合燃料控制系统，包括车载氨氢燃料供给系统、氨氢融合燃料预混燃烧发动机和ECU。
所述车载氨氢燃料供给系统包括低压液氨供给单元和车载制氢单元，其中所述低压液氨供给单元用于提供压力范围为0.5～1MPa的低压氨燃料，包括依次连接的氨存储罐、加热器、稳压罐和压力控制器，所述氨存储罐中装有液氨；所述车载制氢单元用于提供压力范围为1.0～2.0MPa的低压氢气，包括依次连接的车载制氢装置、高压储氢罐和压力控制器；所述压力控制器用控制氨燃料/氢气的压力，优选低压液氨供给单元输出的压力值为0.8MPa，优选车载制氢单元输出的压力值为1.0MPa。制备的低压氨燃料(可以是氨气或是液氨)一路流入所述氨氢融合燃料预混燃烧发动机的氨喷射器4中，另一路流入车载制氢单元用于制氢；制备的低压氢气分为两路送入所述氨氢融合燃料预混燃烧发动机中，一路送入第一氢气喷射器5参与燃烧做功，另一路送入湍流射流点火装置6用于预燃室中参与预燃。
所述ECU用于控制氨氢融合燃料预混燃烧发动机、车载制氢装置和压力控制器，调控待进入氨氢融合燃料发动机的氨燃料和氢气的喷气量及压力值。
如图2所示，所述氨氢融合燃料预混燃烧发动机包括缸套10和设置在缸套10顶部的发动机缸盖9，所述发动机缸盖9顶部设置有进气阀3、排气阀8以及湍流射流点火装置6；所述进气阀3设置在进气通道内，所述排气阀8设置在排气通道内，且进气阀3和排气阀8分别设置在缸盖的左右两侧；所述缸套10内设置有活塞1；所述进气阀3和排气阀8用于结合氨氢融合燃料预混燃烧发动机的节气门装置，改变进气量。发动机缸盖与湍流射流点火装置6和活塞1共同组成主燃烧室2，且所述湍流射流点火装置6位于主燃烧室正上方。其中，所述进气通道上分别设置有朝向所述进气阀3的氨喷射器4和第一氢气喷射器5，喷入进气通道的氨气和氢气在进气通道内形成氨氢融合燃料，且该氨氢融合燃料反应活性由位于进气通道的第一氢气喷射器5调整喷氢量实现，当喷氢量增加，氨氢融合燃料反应活性提高，反之，氨氢融合燃料反应活性降低。所述第一氢气喷射器5由ECU和发动机燃料喷射系统配合控制调控。
其中，所述氨喷射器4为液氨低压喷射器，所述第一氢气喷射器5具有一氢气低压喷嘴。
如图3所示，所述湍流射流点火装置6为配置双喷式预燃室形成带有扫气功能的湍流射流点火装置，具有两种工作模式，分别是双喷射模式和扫气模式。所述湍流射流点火装置6包括一壳体，所述壳体底部通过螺纹安装于发动机缸盖9上；所述壳体内部安装有竖直设置的空气喷射器13和第二氢气喷射器15，所述空气喷射器13和第二氢气喷射器15分别通过一个压紧螺栓14固定于所述壳体上，所述压紧螺栓具有通孔且两端均具有螺纹，一端通过螺纹与壳体连接，用于固定空气喷射器13或第二氢气喷射器15，另一端用于连接气路，所述压紧螺栓的通孔用于将空气送入空气喷射器13或是将氢气送入第二氢气喷射器15。所述壳体下部形成一预燃室内腔11，一火花塞12安装在所述预燃室内腔顶部且火花塞12的电极伸入预燃室中；所述火花塞、所述空气喷射器的喷嘴和第二氢气喷射器的喷嘴设置在所述预燃室的同一侧；所述壳体底部开有射流孔，且所述预燃室与主燃烧室通过射流孔相通。所述空气喷射器和第二氢气喷射器通过ECU和发动机燃料喷射系统配合控制调控。所述射流孔用于实现火焰加速传播，提高燃烧速率，进而提高发动机的经济性。
结合图1，其工作过程为：
氨存储罐中的氨燃料依次流经加热器、稳压罐和压力控制器，ECU用于调控压力控制器中氨燃料的压力为0.5～1.0MPa，随后氨燃料分为两路，一部分经管道进入氨喷射器4，一部分进入车载制氢单元中的车载制氢装置。车载制氢装置制备的氢气依次流经高压储氢罐和压力控制器，ECU调控压力控制器中氢气的压力为1.0～2.0MPa，随后氢气分为两路，一部分由所述第一氢气喷射器5喷入进气通道，进气通道喷射的氢气与氨燃料混合后在主燃烧室形成氨氢融合燃料，其中第一氢气喷射器5的喷氢量由ECU调控，从而在进气通道内实现反应活性可调控的氨氢融合燃料；另一部分供给至湍流射流点火装置6，即由第二氢气喷射器15喷入预燃室内腔11，所述空气喷射器和第二氢气喷射器分别向所述预燃室内腔喷射新鲜空气和氢气，在预燃室内部形成当量混合气，而后由火花塞12点燃，在主燃烧室2中形成射流火焰7，而后点燃主燃烧室2氨氢融合燃料，完成燃烧做功。其中，当所述ECU控制所述湍流射流点火装置为双喷射模式时，空气喷射器13向预燃室内腔11中喷射新鲜空气，同时，当所述ECU控制所述湍流射流点火装置为扫气模式时，只有所述空气喷射器13向预燃室内腔喷射新鲜空气，对预燃室进行扫气。在主燃烧室2混合气过浓或者发动机工作在高EGR率工况时，该扫气过程可消除主燃烧室2中氨气或废气对预燃室氢气/空气混合气着火及燃烧的影响，进而保证射流点火强度，最终实现发动机稳定着火。
同时发动机余热用于向车载氨制氢装置供热，也可以通过安装的电加热装置进行热量供给。图1中虚线表示ECU接收或发出的信号的传递路线。

其工作过程为：所述ECU控制所述湍流射流点火装置为夹气喷射模式时，车载制氢装置制备的氢气一部分由所述第一氢气喷射器5喷入进气通道，另一部分供给第二氢气喷射器17，来自所述第二氢气喷射器17的氢气与来自进气口19的高压空气在所述高压预混腔18内进行预混，形成当量均质预混气，而后均质预混气由电磁阀20喷入预燃室内腔21，而后由火花塞16点燃，在主燃烧室2中形成射流火焰7，而后点燃主燃烧室2氨氢融合燃料，完成燃烧做功。所述ECU控制所述湍流射流点火装置为扫气模式时，所述电磁阀喷射两次，第一次向预燃室内腔21喷射新鲜空气，对预燃室内腔21进行扫气；而后，第二氢气喷射器17中氢气和高压空气在高压预混腔18内混合后形成混合气，由电磁阀第二次喷射进入预燃室内腔21。
以上实施例仅用以说明本发明的技术方案，而非是对其的限制，尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换，而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围，本领域技术人员根据本说明书内容所做出的非本质改进和调整或者替换，均属本发明所要求保护的范围。
