Description
现有技术
本发明涉及根据权利要求1的类型的用于内燃机的燃料喷射装置。
这种燃料喷射装置已由DE 100 04 617 A公开。该燃料喷射装置具有一个高压泵,通过它将燃料输送到一个高压区域中,在该高压区域中例如设有一个高压存储器,即一个所谓的蓄压管(轨Rail)。对于内燃机的每个气缸设有一个用于喷射燃料的喷射器,其中每个喷射器通过一个液压导管与高压存储器相连接。为了控制通过喷射器的燃料喷射,设有一个电控制装置。到喷射器的导管及喷射器为高压区域的组成部分。为了调节出高压区域中的一个确定的压力设有压力调节阀,该压力调节阀通过控制装置来控制。通过该压力调节阀控制高压区域与低压区域的连接。当高压调节阀由控制装置控制时,则它使高压区域与低压区域的连接释放,以致燃料可由高压区域流到低压区域中。在新式的燃料喷射装置中实现了高压区域的完全密封性。当内燃机在长时间工作后停机时,在高压区域中具有的燃料已被加热。在接下来的冷却时由于高压区域的完全密封性可导致燃料的脱气。由此使内燃机的再起动变难,因为首先必需将高压区域中的气体排出。
本发明的优点
相比之下,根据本发明的具有权利要求1特征的燃料喷射装置具有其优点,即在内燃机停机的情况下,当压力调节阀不通过控制装置控制时,高压区域与低压区域相连接,由此可避免高压区域中燃料的脱气。在此,与公知的燃料喷射装置相比不需要任何附加的结构成本。
在从属权利要求中给出了根据本发明的燃料喷射装置的有利的构型及改进。
附图说明
在附图中表示出本发明的多个实施例及在以下的说明中对它们进行详细的描述。
图1以简化示图表示根据第一实施例的用于内燃机的燃料喷射装置,
图2以放大示图表示燃料喷射装置的一个喷射器,
图3以放大示图表示燃料喷射装置的一个压力调节阀,及
图4表示根据第二实施例的燃料喷射装置。
实施例的说明
图1至4中示出用于一个多气缸的内燃机的燃料喷射装置,该内燃机优选为机动车的一个压燃式内燃机。该燃料喷射装置具有一个高压泵10,通过它输送处于高压下的燃料。在内燃机的每个气缸上设有一个喷射器12,通过它可将燃料喷射到气缸的燃烧室中。这里在图1至3中仅表示出这些喷射器12中的一些,其中其它的在最后喷射器12d前的喷射器由点来表示。
喷射器12如图2所示地具有一个燃料喷射阀14,通过它使燃料喷射到气缸的燃烧室中,及具有一个电操作的致动器16。通过该致动器16控制燃料喷射阀14的喷射阀元件15的打开及关闭运动。致动器16优选是一个压电致动器,它根据施加在其上的电压来改变其尺寸。通过该尺寸的改变可实现开关功能,借助该开关功能可使喷射阀元件15打开或关闭。致动器16由一个电子控制装置18控制。致动器16被设置在喷射器12的一个壳体22中的一个注有燃料的室20中。致动器16例如可作用在一个活塞17上,通过该活塞构成了一个控制室19的边界,其中喷射阀元件15通过控制室19中具有的压力在关闭方向上被加载。活塞17通过一个预加载的弹簧21保持靠触在致动器16上。此外,喷射阀元件15通过一个预加载的弹簧23在关闭方向上被加载。当通过控制装置18在致动器16上施加一个电压时,则该致动器伸长并且将活塞17压入控制室19中,由此在该控制室中具有高的压力,通过该压力使喷射阀元件15保持在其关闭位置中,以致不进行燃料喷射。当通过控制装置18对致动器16不施加电压时,则该致动器缩小其延伸长度,以致活塞17通过弹簧21由控制室19向外运动,由此控制室19中的压力下降。喷射阀元件15则通过作用在其上的、作用在打开方向上的高压抵抗控制室19中具有的小压力及抵抗弹簧23的力向其打开位置运动,由此喷射燃料。
在根据图1所示的第一实施例的燃料喷射装置中,通过高压泵10使燃料输送到一个存储器26中。燃料通过一个输送泵30输送给高压泵10,该输送泵由一个燃料储备容器32抽吸燃料。在输送泵30与高压泵10之间可设置一个燃料配置装置34,借助该燃料配置装置可改变由高压泵10输送的燃料量。通过燃料配置装置34例如可调节出一个可改变的流通横截面。燃料配置装置34通过控制装置18控制。
喷射器12各通过一个液压导管36与存储器26相连接。燃料喷射装置的高压区域包括存储器26、由存储器26到喷射器12的液压导管36及喷射器12。在高压区域中设有一个压力传感器40,通过它对控制装置18产生一个在高压区域中具有的压力的信号。此外,在高压区域中设有一个压力调节阀42,它通过控制装置18来控制,以便在高压区域中保持一个预定压力。通过该压力调节阀42可控制高压区域与注有燃料的低压区域的连接44,其中低压区域可为燃料储备容器32或输送泵30的上游或下游的一个区域。压力传感器40及压力调节阀42可设置在高压区域中的任何位置上,例如在高压泵10上,在高压泵10与存储器26之间的液压导管24中,在存储器26上,在存储器26与喷射器12之间的导管36中或在一个喷射器12上。除了通过压力调节阀42控制的连接44外,高压区域对周围不具有连接及完全被密封。
高压调节阀42如图3中所示地具有一个阀元件46,该阀元件具有一个例如为球形的关闭体47,该关闭体与阀座48相互配合及该阀元件通过一个电致动器50,例如一个电磁铁或一个压电致动器可抵抗一个复位弹簧52的力地运动。在此情况下,致动器50通过控制装置18来控制。阀元件46被复位弹簧52在其打开方向上加载,在该方向上该阀元件以其关闭体47由阀座48上抬起及由此打开了高压区域与低压区域之间的连接44。在通过控制装置18起动致动器50时,通过该致动器使阀元件46抵抗复位弹簧52的力及抵抗在高压区域中具有的压力保持在其关闭位置中,在该关闭位置中该阀元件用其关闭体47靠触在阀座48上,使得高压区域与低压区域相断开。通过在高压区域中、例如在存储器26中的压力在打开方向上加载阀元件46,在该打开方向上该阀元件由阀座48抬起及由此打开高压区域与低压区域之间的连接44。当致动器50不被激励时,阀元件46通过高压区域中具有的压力抵抗关闭弹簧的力打开及打开了到低压区域的连接44。当内燃机工作期间燃料配置装置34及压力调节阀42通过控制装置18被这样地控制,以使得在高压区域中建立一个预定的压力,该预定压力正如为燃料喷射所需要的。控制装置18通过压力传感器40得到一个关于高压区域中真实压力的信号。
在内燃机停机时,压力调节阀42不再通过控制装置18激励,以致该压力调节阀位于其打开的开关位置中及高压区域与低压区域形成连接。因此,当高压区域中存在的燃料冷却时高压区域中的容积可由来自低压区域的燃料来填充,以致在高压区域中不形成任何气体。在内燃机的下次起动时压力调节阀42通过控制装置18激励,以致该压力调节阀处于其关闭位置中。在此,在通过高压泵10输送燃料时在高压区域中又很快建立了压力,以致在短的起动时间后内燃机可以工作。
在图4中所示的燃料喷射装置的第二实施例中其结构基本上与第一实施例中相同,但不具有存储器26。第一喷射器12a,即内燃机的最靠近高压泵10布置的喷射器,通过液压导管56与高压泵10连接。下一个喷射器12b通过液压导管58与第一喷射器12a相连接。其余的喷射器12彼此总是通过一个液压导管58相互串联地连接。液压导管56或58各通入喷射器12中的腔20中。在燃料喷射装置的包括液压导管56,58及喷射器12的高压区域中,如在第一实施例中那样设有压力传感器40及压力调节阀42。压力传感器40及压力调节阀42例如可设在高压泵10上,设在高压泵10与喷射器12a之间的导管56中或设置在喷射器12之间的导管58中。压力调节阀42与第一实施例中同样地构成,以致在不由控制装置18激励的状态中它取得其打开的开关位置,高压区域与低压区域的连接44被打开。在根据第二实施例的燃料喷射装置中也可变换地考虑:不仅是第一喷射器12a直接地与高压泵10相连接,而且最后的喷射器12d通过液压导管56也直接地与高压泵10相连接,如图4中由虚线所示。通过喷射器12的燃料喷射阀14喷射的燃料由设有致动器16的室20中取出。在此情况下室20具有足够大的容积,以便可存储用于燃料喷射所需的燃料体积。室20的容积可在1与5cm3之间,例如约为2cm3。
