Description

进气系统的负压进吸气调控方法及装置 技术领域
本发明涉及一种进气系统的负压进吸气调控方法及装置，设有至少一单向活门，其连结至少一连杆组，其具有至少一个不同旋转轴心且适有回复力部，成为一单向活门总成被动因应气流作动开合，以调控进气系统的负压进吸气暨负压源的吸气，供设置于同时具备进气系统和排气系统的机具所设的进气管内使用，例如，内燃机、吸尘器、抽气机、涡轮发动机、包括涡轮喷射(turbojet)、涡轮风扇(turbofan)、涡轮轴(turboshaft)、以及涡轮螺桨(turboprop)等机具。
背景技术
目前已知内燃机(如汽机车引擎)、吸尘器、抽气机、涡轮发动机等设备利用负压进气系统暨负压源产生负压，经由一进气管将外界空气吸入其负压进气系统后再利用一排气系统将空气排出。上述内燃机的负压进气系统例如：自然进气内燃机的汽缸、进气歧管及进气管等，增压作动时增压内燃机的涡轮增压器进气端及进气管等，及增压内燃机的机械增压器进气端及进气管等。上述吸尘器及抽气机的泵浦即为其负压进气系统的负压源。上述涡轮发动机包含有涡轮喷射(turbojet)、涡轮风扇(turbofan)、涡轮轴(turboshaft)、以及涡轮螺桨(turboprop)等，其加压扇叶即为其负压进气系统暨负压源。
以涡轮增压内燃机为例，汽缸在涡轮未作动时，藉负压原理自然进气，即，当涡轮作动时，涡轮进气端仍属负压吸气，而涡轮输出供气端则以正压对汽缸吹送供气。当涡轮作动时，涡轮进气端的进气管段，依PV＝nRT暨相关或该衍生原理，在该进气管段内负压势必上升，所以涡轮进气端会吸入更多空气，且涡轮输出供气端管段内由负压转变成为正压而送出更多空气；此为该类增压器设计诉求。依相同道理，在同时具备进气系统和排气系统的内燃机、吸尘器、抽气机、涡轮发动机就是希望通过负压源以强制负压吸气而吸入更多空气。
提升汽车引擎效益的方法及装置，本发明人曾在先前所申请的美国第 7464694号专利、中国专利ZL200610098538.6、欧洲专利EP2032823、中国台湾专利TWI306133以及其他多国专利(下称现有专利)中讨论。当实施现有专利的技术内容，在具备EGR系统及燃料喷射式内燃机的原厂未改装自然进气汽车的内燃机进气管中设置单向活门时，依PV＝nRT暨相关或该衍生原理，会提升进气管内、安装位置下游负压系统吸气的负压，此提升负压不仅增加进气效率促进燃烧更完全，同时也令现今内燃机技术的废气再循环(Exhaust Gas Recircuration，简称EGR)吸入比原来再更多的排气管废气导入进气系统并入汽缸燃烧，引致燃烧更完全的同时又依EGR原理再行降低燃烧温度而自然再行减少NOx的排放。相同的，该专利技术能提升燃料喷射式涡轮增压内燃机自然进气及涡轮作动时的系统负压，这些情况皆可以经由负压表检验读取而测得。由安装该专利产品的Ford Kuga 1.6L涡轮增压汽油车，因提升实际进气负压让仪表未达原厂设计转速即能提早涡轮作动就是实据。
直至目前为止，全世界具备EGR系统内燃机的汽车所产生的废气排放物中，NOx与HC、CO为相互消长的关系。但除了现有专利的技术之外，目前汽车产业界并未见有可同时降低排放废气中NOx、HC及CO这三种废气含量的技术被使用或报导。
上述现有专利因为提升具备燃料喷射式内燃机负压系统的负压，让汽缸于自然进气时为负压吸入或增压作动时为正压均进入更多空气、造成更完全燃烧而让引擎输出更佳，所以与引擎输出相关联的包括马力、扭力、油耗、空调、发电机，效能均一并全面增益提升；同时，当然也让与进气歧管负压相关的部件(如剎车、EGR、碳罐回收等)的效能一并全面增益提升；即引擎效能全面提升。
是以，未来新生产制造的车辆若纳入现有专利的方法技术，必然能轻易大幅增益各式引擎(如汽油柴油引擎的均质燃烧HCCI、缸内直喷、传统各内燃式引擎等)的燃烧效率，而全面提升引擎效能。其所可达到的功效，经由中国襄阳国家汽车质量监督检测中心检测结果验证(请参下表A装置前报告编号:14-WT-JN-01383、表B装置后报告编号:14-WT-JN-01384)，表A表B为装置现有专利单向活门产品前后的检验值，该等数据显示排气含量中CO由0.81g/km降为0.54g/km，HC由0.12g/km降为0.08g/km，NOx由0.05g/km降为0.02g/km；证实应用现有专利技术的装置能同时大幅降低NOx、HC及 CO的废气排放，更显示产业应用必可大幅降低现有技术关于内燃机燃烧后处理的各项成本。

表B.装置现有专利单向活门产品后的排废气含量
Figure PCTCN2015096548-appb-000002
又2013年北京环科院证实，霾害成因主要来自汽车排放的NOx与VOCs。汽车废气排放中的VOCs必然与HC及CO排放成正比关系，即燃烧完全时HC及CO排放极低，VOCs排放必然极低。可是至今不仅中国，即便全世界，无法快速有效掌控并改善，对于为数庞大的14亿已出厂汽车，无法快速有效掌控并改善，确实是目前无法解决的事实。而前述中国襄阳国家汽车质量监督检测中心的检测报告，证实现有专利单纯的机械式单向活门，确实在不须软硬件匹配的情况下即能直接提升进气管装设位置下游负压系统吸气的负压，并立即大幅有效降低改善汽车排气管废气NOx与HC、CO的排放。
然而，由于现有自然进气汽车在速度增加的行进间，转速越高时其负压区内的负压会越低(由进气歧管连结负压表即可得知)；而上述现有专利的单向活门关闭扭矩只有在静止不作动时最小，据此在汽车速度增加的行进间，该单向活门实际面对进气流量越来越大而相对地负压越来越低，所以、在各进气过程中各行进速度暨各转速的气流与越来越大的单向活门关闭扭矩相当时即形成单向活门平衡开度；若设置的扭簧扭矩越大，则单向活门全程各进气过程中各关闭扭矩自然越大，则进气管中各进气过程中单向活门平衡开度所 形成的气流有效通道就会越小，特别会对引擎在中高转速域时影响进气气流及降低能提升引擎燃烧效率的幅度，导致降低中高转速域能提升输出幅度的现象，是以，仍值得去解决此一问题，改良上述单向活门。
发明内容
有鉴于此，为了改善上述缺点，发明人实测归纳出汽车引擎于行进间维持中高转速域时，若将单向活门关闭扭矩反应至仪表读取的负压值，适当保持在较原来的负压值高一些的设定，即能让引擎燃烧后终端实际输出再大幅增益，遂研发本发明。
本发明的主要目的在提供一种进气系统的负压进吸气调控方法及装置，通过在单向活门上设置连杆组以调整改变单向活叶的关闭扭矩，使该单向活叶于开启后对应该连杆组而作动，进而再提升进气系统负压进气的进气效率。

具体实施方式
请参阅图1、图2，其为本发明进气系统的负压进吸气调控装置的第一实施例，其供设置于具备负压进气系统及排气系统的机具所设的进气管内，包括一单向活门总成，该单向活门总成包括一单向活门1、二连杆组(21、22)、一与该单向活叶旋转轴12不同轴心的连杆组旋转轴23、一回复力部3以及二定位止档件4，其中该单向活门1包含一固定管11，一沿径向方向设置于该固定管11内的单向活叶旋转轴12及二枢设于该单向活叶旋转轴12上的单向活叶13。
各连杆组(21、22)包含一第一连杆(211、221)及一第二连杆(212、222)，其中一连杆组21的第一连杆211的一端与第二连杆212的一端枢接于一连杆转轴213而彼此连接，而该第一连杆211的另端枢接于该连杆组旋转轴23上，该第二连杆212的另端枢接于其中一单向活叶13上，藉以使该连杆组21枢接于该连杆组旋转轴23与该单向活叶13之间。同样地，另一连杆组22的第一连杆221的一端与第二连杆222的一端枢接于一连杆转轴223而彼此连接，而该第一连杆221的另端枢接于该连杆组旋转轴23上，该第二连杆222的另端枢接于另一单向活叶13上。
该回复力部3为一设置于该连杆组旋转轴23上的扭簧(或具有相同作用的任何其他形式弹簧)，且该回复力部3的两端分别枢接于该等连杆转轴(213、223)上，藉以通过各连杆组(21、22)的第二连杆(212、222)而施力其中一单向活叶13，进而形成一可使该单向活叶13朝向定位止档件4移动抵靠的关闭扭矩，并藉该等连杆组(21、22)减少该回复力部3于单向活叶13打开幅度愈 大时所相对增大的关闭扭矩。
该二定位止档件4设置于该固定管11内，以限制该等单向活叶13的位置，使该等单向活叶13于静止未作动全闭状态时可抵靠该等定位止档件4。
在本实施例中，该单向活叶13可处于一静止未作动的全闭状态与一全开状态间开合，该等连杆组(21、22)及该回复力部3经配置使该等单向活叶13静止未作动全闭状态的关闭扭矩(如图3所示)大于该单向活叶13全开状态的关闭扭矩(如图4所示)。在图3中，该等单向活叶13保持最小间隙且不接触该固定管11而呈静止抵靠定位止档件4，其中，回复力部3相对于该连杆组旋转轴23施力旋转法向量大小100展拉连杆组21第一连杆211及第二连杆212以拉动单向活叶13，图中该法向量100的投影分量施力大小101与施力大小102相同。施力大小102相对于单向活叶旋转轴12的投影旋转法向量大小103即为该处单向活叶13关闭的旋转法向量大小。在图4中，该等单向活门呈全开状态，其中，回复力部3相对于该连杆组旋转轴23施力旋转法向量大小200展拉连杆组21第一连杆211及第二连杆212以拉动单向活叶13，图中该法向量200的投影分量施力大小201与施力大小202相同。施力大小202相对于单向活叶旋转轴12的投影旋转法向量大小203即为该处单向活叶13关闭的旋转法向量大小。
产业上调整回复力部3的扭簧材质、线径、圈数及盘圆外径，即可获取设计要求的初始扭矩与最大旋转使用扭矩；在图3及图4中，当施力大小200刻意安排与施力大小100相同、单向活叶13的最开处施力大小203为静止处施力大小103的15.7％；由图示清楚可知，可从调整回复力强度变化、即设置调整扭簧3旋转最开时的扭矩必然大于初始预力圈数时扭矩的比数，用意在实际适当设定令扭簧3反映至施力大小200的实际大小与施力大小100的比数，而可调整决定施力大小203与施力大小103的大小比例，即能由图示的15.7％调整至1点多倍以上；此和现有专利的单向活门最开处使用扭矩必为最大，且必然为静止处扭矩100％以上的情形相比，大不相同。本段阐述为方便说明及比较，单向活叶13最开处的扭簧施力大小200刻意安排如图示与回复力部3(扭簧)施力大小100相同；事实上扭簧施力大小200必然会大于扭簧施力大小100。
由于本实施例中该等连杆组(21、22)及该回复力部3经配置使该等单向活 叶13静止未作动的全闭状态关闭扭矩大于该单向活叶13全开状态的关闭扭矩，其供装设于汽车的负压进气系统的进气管内(例如，设置于自然进气汽车进气管的进气口与节流阀之间)对应该进气管内的进气气流作动，藉以于行进间各转速域时，各种开启状态的单向活叶13的关闭扭矩可使其下游进气歧管中的负压值较未装设该进吸气调控装置时的负压值高一些，能更有效增益进气、让燃烧效率更佳、并让引擎燃烧后终端实际输出再大幅增益。即市区频繁走停用车及高速用车，各对照转速域均能更快速反应，让中低转速有较高输出扭力，而且中高转速域明显提速更快。再由装设本实施例装置于涡轮进气端前管段内的Ford Kuga 1.6L涡轮增压汽油车、相同负荷相同爬坡路段90kph定速比较，原厂涡轮输出正压0.45kg/cm2，安装上考虑要同时兼顾全速域效能的现有专利产品、涡轮输出正压0.5kg/cm2，而安装上考虑要同时兼顾全速域效能的本发明此种设定样品、涡轮输出正压0.57kg/cm2，由0.45kg/cm2、0.5kg/cm2、0.57kg/cm2即能清楚展现本发明进一歩的改良具有更优越的表现。
此外，当2004年Ford Mondeo 2.0L汽油车，装设本实施例的进吸气调控装置与安装应用现有专利的产品相较，除了市区走停更顺畅、更快速反应外，高速公路再加速反应及速度上升亦明显更快；再以油门到底不放方式比较实际末速，安装应用现有专利的产品已增益为180kph，本实施例装置所产生的效率更佳为增加至203kph。再揭、该Mondeo 2.0L车主市区型态用车，每次以平齐加油口的满油至备用油亮灯长时期比较结果，原厂约跑400公里，装置应用现有专利的产品已增益为约跑470公里，而装置本实施例所产生的效率更佳增加至约跑520公里。据此本发明连同现有专利，均实际未更改装置车辆的软件情况下，已能明显超越现有技术而达到让废气排放中的NOx与HC、CO立即大幅降低实属难得。本发明首先公开此种技术手段，凡对于本发明所属技术领域技术人员，依据本发明说明而再产生的单向活门关闭扭矩的变化，只要始大于末情况的，均应属于本发明所公开的技术范围。
在另一实施例中，该连杆组及该回复力部(例如弹簧)经配置使该单向活叶静止未作动的全闭状态关闭扭矩小于该单向活叶全开时的关闭扭矩。此种技术设定适合中高转速域如发电机、如增程电动车的内燃机，需求多为中高转速发电的使用输出情况；不仅可以明显低于原转速即能达到相同输出， 特别是节能及废气排放，更有极优越的表现。再者以实物比较，用相同规格扭矩弹簧装置于相同规格单向活叶的本实施例与相同规格扭矩弹簧装置于相同规格单向活叶的现有专利的产品比较，设置二者初始预力相同、即二者未作动的全闭状态单向活叶的关闭扭矩相近或相同，因二者单向活叶全开的角度相近或相同，但在连杆组的设置作用下，本实施例单向活叶全开时的关闭扭矩，可以明显小于现有专利的产品单向活叶全开时的关闭扭矩，显然更具有优越的效果。本发明首先公开此种技术手段，凡对于本发明所属技术领域技术人员，依据本发明说明而再产生的单向活门关闭扭矩的变化，只要始小于末情况的，亦均应属于本发明所公开的技术范围。
在又一实施例中，该连杆组及该回复力部(例如弹簧)经配置使该单向活叶静止未作动的全闭状态关闭扭矩几乎与该单向活叶全开时的关闭扭矩相同。此种技术设定特别适合主要诉求为节能的一般国民车，即市区频繁走停中低转速能有较高输出扭力，当然又因为节能主诉求，所以必然妥协降低些许中高转速域的高效输出。本发明首先公开此种技术手段，凡对于本发明所属技术领域技术人员，依据本发明说明而再产生的单向活门关闭扭矩的变化，只要始末相当情况的，亦均应属于本发明所公开的技术范围。
因此，本发明不仅只是将同样单向活门设置于进气系统的负压进气管中，而是再通过连结至少一组连杆组构成单向活门总成，达到改良的效果，其使用效益超越现有专利中的单向活门。另本发明更进一步可掌握，在各种应用场合情况，如上所述，可分别设定单向活门关闭扭矩静止时与角度最开时比较为较大、较小或相当，应用更精进的连杆组与回复力部而适当地调整单向活门开合扭矩的始末变化比数，并可针对不同需求作明显不同的改变配合，此又为已公开的现有专利单向活门在角度最开时单向活门关闭扭矩恒为最大的情形所无法达成的。此外，本发明亦可应用于其他类型的进气系统的负压进气管中，例如上述的吸尘器、抽气机或涡轮发动机。
又，航空器最怕鸟袭等异物侵入涡轮发动机，尽管航空器制造公司已提升机具零件耐撞击强度，但至今终究尚未有栅栏先导隔离，无疑应是进气管道栅栏影响进气。如应用本发明装置或方法，牺牲小部分大幅增益的进气效益，而换取可在进气管口外匹配具适当夹角的异物强制脱离栅栏，仍可达到整体进气增益的效果，从而可以强制隔离排除且大幅降低鸟袭等异物侵入造 成无法弥补的严重损害，大幅提高航空器飞行安全。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；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。
