Description

使用涡轮增压器将空气供给到减排装置的方法和设备
技术领域
本公开总体上涉及一种减排装置。
背景技术
减排装置用于处理多种排气的排放物。例如，已有减排装置用于除去排气颗粒物质、NOx(即，氮氧化物)、碳氢化合物以及一氧化碳。
发明内容
根据本公开的一个方面，提供了一种设备，包括内燃机、减排装置和涡轮增压器。减排装置在流体上连接到发动机，以从发动机接收排气。涡轮增压器包括空气压缩机，空气压缩机在流体上连接到发动机，以将增压空气供给到发动机，并且空气压缩机经由不包括发动机的任何燃烧部分的流路在流体上连接到减排装置，以将增压空气供给到减排装置。本发明还公开了一种相关的方法。
根据本公开的另一方面，一种设备包括：减排部件；回热器，其构造成产生用于减排部件再生的热量；以及涡轮增压器，其包括空气压缩机，空气压缩机经由不包括任何发动机燃烧部分的流路在流体上连接到回热器，以将增压空气供给到回热器。
通过下面的描述和附图，本公开的上述及其他特征将变得明显。
附图说明
图1是一个简化框图，示出了使用涡轮增压器将增压空气供给到发动机和减排装置；
图2是减排装置的第一实施方式的简化框图；以及
图3是减排装置的第二实施方式的简化框图。
具体实施方式
虽然本公开的原理适于多种变型和替代形式，但在附图中还是以示例方式示出了一些具体的示例性实施方式，并且将在这里对其进行详细描述。然而应当理解，这并不是意图将本公开限制于所公开的特定形式，相反，本发明覆盖了落入所附权利要求限定的本发明精神和范围内的所有变型、等同方式以及替代方式。
参照图1，示出的设备10包括用于将增压空气供给到内燃机14(例如，柴油发动机)和减排装置16的涡轮增压器12，减排装置16构造为从发动机14的排气(图中的标记“EG”)中去除排放物。发动机14在其燃烧部分中将从燃料供给装置18接收的燃料与从涡轮增压器12接收的增压空气进行燃烧，从而产生用于操作涡轮增压器12的排气。减排装置16将从燃料供给装置18接收的燃料与从涡轮增压器12接收的增压空气进行燃烧，以去除排气排放物。
涡轮增压器12包括涡轮机20和通过涡轮机20操作的空气压缩机22。涡轮机20的排气入口24在流体上连接到发动机14的排气出口26，以从其接收排气。排气流过涡轮机20，以使涡轮机20操作空气压缩机22。然后，排气通过排气出口28排出涡轮机20，从而流到减排装置16的排气入口30，其中减排装置16的排气入口30经由排气管线31在流体上连接到涡轮机20的排气出口28。经过减排装置16的处理后，排气通过减排装置16的排气出口32排出减排装置16。
空气压缩机22以机械方式耦联到涡轮机20，因此响应穿过涡轮机20的排气流动而被操作。空气压缩机22的操作使空气(如未增压空气，例如周围空气)通过空气过滤器34进入空气压缩机22的空气入口36。空气压缩机22对空气增压，并通过空气出口38将增压空气排入空气供给管线40。
空气供给管线40中的增压空气流在汇合部42处被分为发动机气流和装置气流。发动机气流经由连接汇合部42与发动机空气入口44的发动机空气管线45从汇合部42流到发动机14的空气入口44。发动机空气管线45中的中间冷却器46在发动机空气流进入发动机14之前将其冷却。因此空气供给管线40和发动器空气管线45协作限定出用于将增压空气从涡轮增压器12导向发动机14的流路。
装置气流经由连接汇合部42与装置空气入口48的装置空气管线50从汇合部42流到减排装置16的空气入口48。装置空气管线50中的空气阀52可被操作以控制增压空气从空气压缩机22到减排装置16的流动，并且因此控制增压空气从空气压缩机22到发动机14的流动。因此空气供给管线40和装置空气管线50协作以限定出用于将增压空气从涡轮增压器12导向减排装置16的流路。这个流路不包括发动机14的任何燃烧部分53(例如，任何发动机燃烧室)，因此供给到减排装置16的增压空气没有在发动机14中与燃料发生燃烧。
空气阀52可以采用多种形式。在一些示例中，空气阀52可以是比例阀(例如蝶形阀)。在其它示例中，空气阀52可以是与装置空气管线50中的气流计量孔结合使用的开/关断流阀(例如电磁阀)。
燃料供给装置18将燃料供给到发动机14和减排装置16。同样，燃料供给装置18经由发动机燃料管线55在流体上连接到发动机14的燃料入口54以给发动机14供给燃料，并且经由装置燃料管线57在流体上连接到减排装置16的燃料入口56以给装置16供给燃料。燃料供给装置可以包括同时用于发动机14和减排装置16的单燃料罐和燃料泵，或者可以包括分别用于发动机14和减排装置16的独立的专用燃料罐和燃料泵。
控制系统58控制发动机14、减排装置16、空气阀52以及燃料供给装置18的操作。控制系统58经由电线60电连接到发动机14以控制发动机14的操作，经由电线64电连接到空气阀52以控制阀52的操作，并且经由一条或多条电线65电连接到燃料供给装置18以控制燃料供给装置18的操作。根据减排装置16的类型，控制系统58还可以经由电线62电连接到减排装置16以控制装置16的操作。电线62代表在控制系统58与减排装置16之间的任何类型的适合的电连接，这些都在本公开的范围内。
控制系统58可以采用多种形式。在一些示例中，控制系统58可以包括：发动机控制单元(“ECU”)66，用于控制发动机14的操作；以及控制器68，用于控制空气阀52的操作并且在适合时控制减排装置16的操作。在这种情况下，ECU 66和控制器68中的每一个可以经由独立的电线65控制燃料供给装置18的操作，以将燃料分别供给到发动机14和装置16，并且ECU 66和控制器68可以经由电线70(例如CAN链路)彼此电连接，以便在它们之间进行通讯。在其它示例中，控制器68集成在ECU 66中。在这种情况下，可以仅存在一条电线65用于与燃料供给装置18通讯。
ECU 66可以构造成以两种发动机控制模式操作。在这种情况下，当空气阀52关闭以阻断增压空气从压缩机22流到减排装置16时，ECU66以第一发动机控制模式操作，使得所有的增压空气从压缩机22流到发动机14。在第一发动机控制模式中，ECU 66根据第一发动机映射方案操作发动机14。当空气阀至少部分开启时，ECU 66以第二发动机控制模式操作，使得增压空气从压缩机22流到发动机14和减排装置16。示例性地，大约95％的增压空气可以流到发动机14，而余下的5％的增压空气流到减排装置16。在第二发动机控制模式中，ECU 66根据第二发动机映射方案操作发动机14，从而使得流到发动机14的空气减少。
参考图2，示出了减排装置116，其被构造成用作设备10中的减排装置16。装置116包括回热器120，回热器120产生热量，以便燃烧掉颗粒过滤器124捕集的颗粒物质。产生的热量与排气中存在的氧气共同将捕集的颗粒物质氧化，从而使过滤器124再生用于进一步的使用。控制系统58操作空气阀52、燃料供给装置18以及回热器120，从而根据需要以规律或无规律的时间间隔(例如每天1-4次)和/或根据一些其它的预定再生标准使过滤器124再生。
示例性地，回热器120构造成燃烧器。在这种情况下，回热器120从装置燃料管线57接收燃料、经由雾化空气管线59从雾化空气供给装置61接收较高压力的燃料雾化空气，并且经由装置空气管线50从空气压缩机22接收较低压力的燃烧空气。雾化空气供给装置61可以是具有设备10的车辆的空气制动系统。雾化空气用于雾化燃料，以促进燃料与燃烧空气的燃烧。燃烧空气与雾化空气相比具有较低的压力，并且会被引入到回热器120的燃烧室用于与燃料一起燃烧。经由连接装置62从控制系统58接收的电能用于点燃燃烧室中的燃料。空气压缩机22能够向回热器120供给体积相对相对较大的燃烧空气，以满足回热器120对燃烧空气的需要。因此，由回热器120产生的热量用于在过滤器124的再生中使用。为了公开适合的回热器120，在此将2004年8月31日提交并转让给本申请的相同受让人的美国专利申请第10/931,028号以及2004年7月20日提交并转让给本申请的相同受让人的美国专利申请第10/894,548号以引用方式并入本文。
减排装置116包括一个位于回热器120上游的空气-燃料混合器也在本公开的范围内。在这种情况下，混合器将从装置空气管线50接收的空气与从装置燃料管线57接收的燃料混合，并且将空气-燃料混合物供给到回热器用来燃烧，从而产生用于燃烧由过滤器124捕集的颗粒物质的热量。
参照图3，示出了减排装置216，其被构造成用作设备10中的减排装置16。装置216的燃料重整器218使用经由装置空气管线50从涡轮增压器12供给的增压空气，将经由装置燃料管线57从燃料供给装置18供给的燃料重整为重整气(例如，氢气(H2)、一氧化碳(CO))。重整气经由用于连接减排部件220的重整气管线222进入减排部件220。排气也经由排气管线31进入减排部件。
燃料重整器218可以具体化为任何类型的燃料重整器，例如催化燃料重整器、热燃料重整器、蒸气燃料重整器或者任何其他类型的部分氧化燃料重整器。燃料重整器218还可以具体化为等离子体燃料重整器，其利用等离子体(即电弧)将空气和烃类燃料的混合物转化为重整气。美国专利第5,425,332号、第5,437,250号、第5,409,784号和第5,887,554号、美国专利申请第10/452,623号以及美国临时专利申请第60/660,362号公开了包括等离子体燃料重整器的系统，在此将这些公开以引用方式并入本文。在燃料重整器218是等离子体燃料重整器的情况下，电线62将电能供给到重整器218以在其中产生用于将燃料重整为重整气的等离子体。
部件220可以采用多种形式。在一个示例中，部件220是NOx吸附器，其捕集处于稀薄状态下的NOx。流过NOx吸附器的排气可以通过重整器218的操作不时地富化。在这种富化状态下，捕集的NOx被释放并且还原为氮。根据另一个示例，所述部件是选择性催化还原催化剂，其对重整气的一种或多种成分与排气中存在的NOx之间的反应进行催化，从而减少NOx。在另一示例中，所述部件是颗粒去除装置，其形式为催化颗粒过滤器或者氧化催化剂与催化的或未催化的颗粒过滤器的结合。根据又一示例，所述部件可以是柴油颗粒NOx消减装置(“DPNR”)，其构造为集成的NOx吸附器与颗粒过滤器。
虽然已在附图和前面的描述中对本公开的原理进行了详细图示和说明，但是这样的图示和说明在性质上应该被认为是示例性的而非限制性的，应当理解，仅示出和描述了示例性的实施方式，而且落入本公开的精神范围内的所有改动和变型都期望受到保护。
从此处描述的系统的各种特征来看，本发明的原理具有多个优点。应当指出，本公开的每个系统的替代实施方式可以不包括描述的所有特征，但仍然可从这些特征的至少一些优点中受益。本领域的普通技术人员可以容易地设计出他们自己的包括本公开一个或多个特征的系统的实施方式，这些实施方式仍然落入所附权利要求限定的本发明的精神和范围内。
