Description

双燃料车辆的LPG充补系统
技术领域
本发明涉及双燃料车辆的液化石油气(LPG)充补系统。更具体地，本发明涉及这样的双燃料车辆的LPG充补系统：其构造为，在外部温度很高的情况下(例如在炎热季节)，降低用于储存LPG的LPG储罐中的温度和压力，其中能够用LPG再充补LPG储罐。
背景技术
使用汽油和LPG两者的双燃料车辆分别装配有包括汽油箱的汽油供应系统和包括LPG储罐的液化石油气(LPG)供应系统。
如图1所示，用LPG充补双燃料车辆的LPG储罐的过程包括：操作LPG充补站的充补泵2的步骤，通过操作充补泵2而将LPG从LPG充补站的LPG储存空间1供应至注冲枪3的步骤，和利用注冲枪3而用LPG充补车辆的LPG储罐的步骤。
然而，在外部温度很高的情况下(例如在炎热季节)，车辆的LPG储罐中的压力可能高于LPG充补压力，因此不能进行LPG充补。
也就是说，在车辆的LPG储罐中的压力高于LPG充补压力的情况下，安装于储罐的LPG喷注口的溢流阀的止回阀不打开，因此不能利用注冲枪用LPG充补LPG储罐。
例如，当炎热季节的大气温度为约40℃或更高时，车辆的LPG储罐中的压力变得高于(例如16.5bar)注冲枪中的LPG充补压力(例如16.3bar＝LPG充补站的LPG储存空间中的压力8.3bar+由于操作充补泵而得到的LPG泵送压力8.0bar)。因此，安装于储罐的LPG喷注口中的溢流阀的止回阀不打开，因此不能利用注冲枪用LPG充补LPG储罐。
公开于本发明的背景部分的信息仅仅旨在加深对本发明的一般背景技术的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域技术人员所公知的现有技术。
发明内容
本发明的各个方面旨在提供双燃料车辆的LPG充补系统，其构造成：利用汽油箱中的汽油温度低于LPG储罐中的LPG温度的事实，通过将一些汽油从汽油箱供应至LPG储罐而冷却LPG储罐的内部并且降低LPG的蒸汽压力，其中，即使在外部温度很高的情况下(例如在炎热季节)，也能够容易地用LPG再充补LPG储罐。

在又一个示例性实施方案中，LPG储罐中可以具有分隔壁，以将LPG储罐的内部分隔成设置有喷嘴的空间和设置有LPI泵的空间，并且用于避免汽油被直接供应至LPI泵。
在又一个示例性实施方案中，控制器可以基于来自安装于LPG储罐的LPG计量器的剩余LPG量测量信号和来自安装于汽油增压管线的流量计的汽油供应量测量信号来控制电磁阀打开的时间量，从而确定供应至LPG储罐的汽油的量。
在另一个示例性实施方案中，可以使用安装于LPG供应管线和LPG返回管线的调节器的压力传感器来测量LPG储罐中的压力。

在这些图中，贯穿附图的多幅图，附图标记涉及本发明的相同或等同的部分。
具体实施方式
下面将详细参考本发明的各个实施方案，这些实施方案的示例被显示在附图中并描述如下。尽管本发明将与示例性实施方案相结合进行描述，应当理解本说明书并非旨在将本发明限制为那些示例性实施方案。相反，本发明旨在不但覆盖这些示例性实施方案，而且覆盖可以被包括在由所附权利要求所限定的本发明的精神和范围之内的各种选择形式、修改形式、等价形式及其它实施方案。
如上所述，双燃料车辆分别装配有包括汽油箱的汽油供应系统和包括LPG储罐的液化石油气(LPG)供应系统。
如图2所示，汽油箱10和LPG储罐20分别安装至双燃料车辆的底盘。根据双燃料车辆的布局，LPG储罐20和排放气体排出线路12之间的距离小于汽油箱10和排放气体排出线路12之间的距离因此，相对于LPG储罐20，汽油箱10受到热源的影响较小。
因此，汽油箱10中的汽油温度维持为低于LPG储罐20中的LPG温度。
此外，从汽油箱供应至发动机的汽油燃烧而不返回至汽油箱，而从LPG储罐供应至发动机的LPG的未燃烧部分返回至LPG储罐。
在LPG温度由于发动机的燃烧热而增加的状态下，由于LPG从发动机返回至LPG储罐，所以LPG储罐中的温度增加。
因此，LPG储罐中的温度变得高于汽油箱中的温度。此外，在外部温度很高的情况下(例如在炎热季节)，LPG储罐中的温度进一步增加，同时LPG储罐中的压力也增加。然而，当LPG储罐中的压力变得高于LPG充补压力时，不能进行LPG充补。
为了解决该问题，本发明的特征在是：考虑到汽油箱中的汽油温度低于LPG储罐中的LPG温度，将汽油箱中的一些汽油供应至LPG储罐，以使用供应的汽油来冷却LPG储罐的内部并且降低LPG的蒸汽压力，因此平稳地实现用LPG再充补LPG储罐。
在此，将描述根据本发明的各个示例性实施方案的双燃料车辆的LPG充补系统的构造。
图3为显示根据本发明的各个示例性实施方案的双燃料车辆的LPG充补系统的构造的示意图。在图3中，附图标记10表示用于储存汽油的汽油箱，附图标记20表示用于储存LPG的LPG储罐。
汽油箱10和LPG储罐20连接至单个发动机30，以分别将汽油和LPG供应至发动机30。
特别地，汽油箱10经由汽油供应管线11而连接至发动机30，并且LPG储罐20经由LPG供应管线21而连接至发动机30。
LPG储罐20还经由LPG返回管线22而连接至发动机30。具有压力传感器23的调节器24安装于LPG供应管线21和LPG返回管线22。
当来自LPG储罐20的LPG经由LPG供应管线21供应至发动机30，并且未燃烧的LPG经由LPG返回管线22返回至LPG储罐20时，调节器24控制LPG的流动并且检测LPG的压力。
特别地，当来自LPG储罐20的LPG经由LPG供应管线21供应至发动机30时，包括于调节器24的压力传感器23检测穿过调节器24的LPG的压力，并且将检测到的压力作为表示LPG储罐20中的压力的信号而传递至控制器(ECU)50。
根据本发明的示例性实施方案，LPG储罐20设置有喷嘴40，以将汽油从汽油箱10喷入LPG储罐。利用喷嘴40喷入的汽油与LPG储罐的内部空间和LPG储罐中的LPG交换热量，从而冷却LPG储罐和LPG储罐中的LPG。
从汽油供应管线11分支的汽油增压管线13连接至喷嘴40。
也就是说，从连接在汽油箱10和发动机30之间的汽油供应管线11分支的汽油增压管线13可连通地连接至安装于LPG储罐20的喷嘴40。
可以使用射流喷嘴(其为一种射流泵)作为喷嘴40，所述射流喷嘴构造为将来自汽油增压管线13的固定量的汽油喷入LPG储罐20。
使用射流喷嘴作为喷嘴40，使得当高压流体(即，汽油)被喷入低压膨胀空间(即，LPG储罐)时，流体颗粒粉末化，从而引起蒸发热(即，吸热反应)。
同时，连接在汽油箱10和喷嘴40之间的汽油增压管线13设置有增压泵43、压力传感器42和电磁阀41，它们从汽油箱开始依次设置。
当LPG储罐中的压力到达上参考值(例如，11bar)时，驱动增压泵43，从而将来自汽油箱10的汽油增压至高于LPG储罐中的压力，使得汽油利用喷嘴40而容易地移动进入LPG储罐20。
压力传感器42用于检测增压泵43是否正常操作。压力传感器42检测从汽油箱10经由增压泵43而流动至喷嘴40的汽油的供应压力，并且将检测到的压力传递至控制器50。
当通过压力传感器42检测到的汽油的供应压力低于参考值(例如，12bar)时，控制器50进行控制。以使得电磁阀41关闭。其原因在于，当汽油的供应压力低于参考值(例如，12bar)时，来自LPG储罐20的LPG会通过处于打开状态的电磁阀41而向汽油箱10反向流动。
响应于来自控制器50的控制信号，电磁阀41打开或关闭，从而允许或中断从汽油箱10至喷嘴40的汽油流动。
如图4所示，流量计44用于测量供应至LPG储罐20的汽油的量并且将测量结果传递至控制器50，该流量计44在接近喷嘴40的汽油增压管线13处进一步安装于汽油增压管线13。
LPG计量器45安装于LPG储罐20，所述LPG计量器45用于测量LPG储罐20中的剩余LPG量。通过LPG计量器45测量的剩余LPG量作为表示剩余LPG量的信号传递至控制器50。
当确定从压力传感器23接收的LPG储罐20中的压力等于或高于参考压力时，控制器50进行控制，使得电磁阀41打开。此外，基于从LPG计量器45接收的LPG储罐20中的剩余LPG量，控制器50控制电磁阀41打开的时间。
来自汽油箱10的汽油穿过电磁阀41，通过喷嘴40喷入LPG储罐20，并且与LPG储罐的内部空间和LPG储罐中的LPG交换热量。因此，LPG储罐的内部被冷却。因此，LPG储罐中的温度降低，并且LPG的蒸汽压力也降低。
由于LPG储罐20的内部被冷却并且LPG的蒸汽压力降低，所以LPG储罐20中的压力变得低于上参考值。因此，可以容易地用LPG再充补LPG储罐20。
当汽油与LPG混合时，汽油降低LPG的蒸汽压力，因为汽油的温度低于LPG的温度。
汽油和LPG为包含C和H的化合物(汽油和LPG彼此的不同之处仅在C原子和H原子的数目)。因此，当汽油与LPG混合时，混合物可以无问题地燃烧。然而，为了遵守相关法规，控制器50可以控制电磁阀打开的时间量，以使得供应至LPG储罐的汽油的量小于LPG的量的10％。
如图4所示，分隔壁18安装于LPG储罐20，以将LPG储罐20的内部分隔成设置辅助室的空间和设置LPI泵28的空间。分隔壁18避免汽油被直接供应至LPI泵。
下文将描述根据本发明的各个示例性实施方案的具有上述构造的双燃料车辆的LPG充补系统的操作。
图5为控制器执行的流程图，并且显示了根据本发明的各个示例性实施方案的双燃料车辆的LPG充补系统的操作，图6为显示根据本发明的各个示例性实施方案的LPG储罐冷却系统的操作的示意图。
首先，感应LPG储罐20中的压力。
特别地，使用压力传感器23检测LPG储罐20中的压力，并且将检测到的压力作为信号传递至控制器50。
因此，控制器将LPG储罐20中的压力与上参考值(例如，11bar)进行比较(S101)。
当LPG储罐20中的压力低于上参考值(例如，11bar)时，控制器50进行控制，以将电磁阀41构造为关闭(S102)。
由于电磁阀41关闭，所以来自汽油箱10的汽油仅供应至发动机。亦即，来自汽油箱10的汽油不供应至LPG储罐20。
当LPG储罐20中的压力高于上参考值(例如，11bar)时，控制器50进行控制，使得增压泵43通电并且因此得到驱动(S103)。
因此，从发动机流动至汽油增压管线13的汽油的压力增加(例如，从5bar至12bar)。
此时，安装于汽油增压管线13中的压力传感器42检测汽油的压力，并且将检测到的汽油压力传递至控制器50。
因此，控制器将汽油压力(特别是汽油增压管线13中的汽油压力)与高于LPG储罐中的压力的参考值(例如，12bar)进行比较(S104)。当汽油压力高于参考值时，控制器50进行控制，使得电磁阀41构造为打开(S105)。
因此，如图6所示，由于汽油泵14的操作，来自汽油箱10的汽油被供应至发动机。同时，由于增压泵43的操作，一些汽油经由电磁阀41被供应至喷嘴40，并且通过喷嘴40被喷入LPG储罐20。
当汽油通过喷嘴40(其可以为射流喷嘴)被喷入LPG储罐时，一些汽油粉末化，以引起蒸发热(即，吸热反应)。此外，汽油与LPG储罐的内部空间和LPG储罐中的LPG进行热量交换。因此，LPG储罐的内部被冷却。因此，LPG储罐中的温度和LPG储罐中的LPG的温度降低。此外，LPG的蒸汽压力也降低。
此时，相比于LPG储罐中的压力(例如，11bar)，由于蒸发热造成的LPG的蒸汽压力极小(例如0.44至0.82bar)。当汽油蒸发时，由于汽油造成的LPG储罐中的压力增加极小。相反，LPG储罐中的温度由于汽油的蒸发而降低。
控制器50被构造成确定是否由于LPG储罐20的内部被冷却并且LPG的蒸汽压力降低而使LPG储罐20中的压力已经降低为小于参考压力(例如，8bar)。当LPG储罐20中的压力已经降低为小于参考压力(例如，8bar)时(这意味着能够用LPG再充补LPG储罐)，控制器50进行控制，使得电磁阀41和增压泵43关闭(S107和S108)。
同时，控制器50基于来自LPG计量器45的信号而检测LPG储罐中的剩余LPG量，同时检测表示供应至LPG储罐的汽油量的来自流量计44的信号，从而控制电磁阀41打开的时间。
控制器50可以控制电磁阀41打开的时间量，使得供应至LPG储罐的汽油的量小于LPG的量的10％。
同时，应用根据本发明的示例性实施方案的LPG充补系统的双燃料车辆的行驶模式分成使用汽油的汽油模式和使用LPG的LPG模式。然而，即使在LPG模式下，仍然执行汽油模式直至LPG储罐中的压力降低为小于参考压力(例如，约8bar)。
如上所述，在外部温度很高的情况下(例如在炎热季节)，使用温度低于LPG温度的汽油而将LPG储罐的内部冷却并且使LPG的蒸汽压力降低。因此，能够降低LPG储罐中的压力。因此，能够用LPG再充补LPG储罐。
下文将描述根据本发明的各个示例性实施方案的双燃料车辆的LPG灌装系统的构造和操作。
图7为显示根据本发明的各个示例性实施方案的双燃料车辆的LPG充补系统的构造的示意图。在图7中，附图标记46表示止回阀。
图7中的根据本发明的各个示例性实施方案的LPG充补系统的构造和操作与之前的根据本发明的各个示例性实施方案的LPG充补系统的构造和操作相同，不同之处仅在于使用单向止回阀46代替各个示例性实施方案中的电磁阀41。
通过控制器50控制电磁阀41的打开或关闭。然而，在该实施方案中，止回阀46将一些汽油从汽油箱供应至LPG储罐而不受控制器的控制。
为了使止回阀46将一些汽油从汽油箱供应至LPG储罐，必须考虑止回阀的规格和打开操作压力。
为此目的，止回阀46的操作压力(即，可以施加至止回阀以打开止回阀的压力)被设定为低于可归因于汽油泵14的操作的汽油排出压力和可归因于增压泵43的操作的汽油增压压力的总和并且高于仅可归因于汽油泵14或增压泵43的操作的汽油排出压力。
更特别地，止回阀46可以构造为：当可归因于汽油箱中的汽油泵14的操作的汽油排出压力和可归因于增压泵43的操作的汽油增压压力的总和施加至止回阀46时，止回阀46打开，当仅可归因于汽油泵14或增压泵43的操作的汽油排出压力施加至止回阀46时，止回阀46不打开。
根据本发明的各个示例性实施方案，即使在使用止回阀代替电磁阀的情况下，也可以利用汽油箱中的汽油温度低于LPG储罐中的LPG温度的事实而容易地将一些汽油从汽油箱供应至LPG储罐。因此，能够冷却LPG储罐的内部并且同时降低LPG储罐中的压力。因此，能够容易地用LPG再充补LPG储罐。
图7中的根据本发明的各个示例性实施方案的LPG充补系统的构造和操作与之前的根据本发明的各个示例性实施方案的LPG充补系统的构造和操作相同，不同之处仅在于使用止回阀代替电磁阀，因此将省略其详细描述。
通过以上描述明显的是，本发明具有如下效果。
根据本发明的示例性实施方案，在外部温度很高的情况下(例如在炎热季节)，使用温度低于LPG温度的汽油冷却LPG储罐的内部并且降低LPG的蒸汽压力。因此，能够降低LPG储罐中的压力，能够容易地用LPG再充补LPG储罐。
也就是说，利用汽油箱中的汽油的温度低于LPG储罐中的LPG的温度的事实，通过将一些汽油从汽油箱供应至LPG储罐，能够冷却LPG储罐的内部并且同时降低LPG储罐中的压力。因此，能够容易地用LPG再充补LPG储罐。
