Description

用于排气后处理的设备以及用于运行设备的方法
技术领域
本发明涉及一种用于对燃烧发动机进行排气后处理的设备，该设备具有用于燃料的储箱、流体输送装置和燃烧发动机的排气导管。
背景技术
用于排气后处理的设备是已知的并且广泛流行的。在已知的并且有效的设备类型中，将额外的燃料喷射到排气管路中，并且借助剩余的氧气在排气中燃烧。为此需要以适合的方式布置喷射装置并且需要足够长的混合距离，以获得令人满意的效果，尤其排气温度的提高。
发明内容
本发明的目的是，向排气导管中引入燃料并且取决于燃烧发动机的运行状态使用适合的、不同的手段，以便精细地分配燃料或在已经燃烧的状态下改变燃烧发动机的排气的温度和成分。
本发明的解决方案通过具有第一权利要求的特征的设备以及通过具有独立权利要求10的特征的方法来实现。
本发明包括以下技术传授内容：流体输送装置具有两个剂量泵，其中电磁驱动的第一剂量泵能够藉由喷射装置或蒸发器供应由该电磁驱动的第一剂量泵从该储箱取出的燃料，并且其中该喷射装置或该蒸发器能够将该燃料送入该排气导管中。
电磁驱动的第二剂量泵能够将由其从该储箱取出的燃料供应给燃烧装置，其中该燃烧装置与能够为其供应空气的压缩机处于连接中，并且其中该燃烧装置能够将其燃烧产物送入该排气导管中。
因为存在两个剂量泵，因此可以以简单且受控制的方式来适配依赖于燃烧发动机的运行条件将燃料引入排气管路中的方法。电磁驱动的剂量泵允许以非常简单的方式调节每个时间单元的输送量，即通过调节电磁体处电信号的频率。
从属权利要求包含本发明的有利改进方案。
有利地，在第一实施方式中，根据本发明的设备具有排气涡轮增压器，该排气涡轮增压器由该压缩机和由燃烧发动机的排气驱动的涡轮机组成，其中该压缩机还能够提供该燃烧装置提供所需的空气。
当存在排气涡轮增压器时，这形成供应目的的非常低价的解决方案。
在第二实施方式中，根据本发明的设备具有由电动机驱动的压缩机，当接通了该电动机时，该压缩机能够提供该燃烧装置提供所需的空气。
在此解决方案中，不依赖于排气涡轮增压器并且具有用于接通和切断空气流的简单的可能性。
有利地，喷射装置具有电磁致动的喷射阀、喷嘴和进入排气导管的出口。
替代于喷射装置，可以设置有蒸发器，该蒸发器可以将燃料引入排气导管中，其中蒸发器以已知的方式由壳体、电加热的预热棒、用于燃料的入口和出口组成。
当排气具有足够高的温度时，喷射装置或蒸发器使得所引入的燃料与排气很好地混合。
同样有利地，燃烧装置具有用于将空气与燃料混合的混合装置以及燃烧室，其中有利地，该燃烧室与该排气导管经由旁通管路处于流体连接。
当排气仍然具有相当低的温度时，提出使用燃烧物。
优选地，这些电磁驱动的剂量泵被实施为往复活塞泵，其中电磁体相应地抵抗复位弹簧驱动平移作用的挤压器单元。
往复活塞泵构造得非常简单并且允许以非常简单的方式通过改变控制频率来改变每个时间单元上的输送量。
这些剂量泵有利地被实施为在内部被流经的往复活塞泵，其中该电磁体的磁体线圈能够各自被由该剂量泵输送的燃料流经。
由于在内部被流经的往复活塞泵的构造方式，往复活塞的动态作用的密封是不必要的，由此实现对剂量泵的非常可靠的向外密封。
有利地，这些剂量泵各自具有与挤压器单元的往复活塞力配合或形状配合地连接的锁止装置，该锁止装置以与配合元件共同作用的方式在剂量泵的由复位弹簧预先确定的静止状态下防止流经剂量泵(当相应的电磁体未通电时)。由此，在静止状态下防止燃料的续流或在静止状态下防止燃料的回流。
有利地，根据本发明的设备具有温度传感器，该温度传感器将该排气导管中的气体温度报告给由程序控制的电控制器，其中该电控制器分别给这些剂量泵的电磁体施加由脉冲激发的电流，并且其中由脉冲激发的电流可以相对于这两个电磁体具有不同的电流强度和不同的脉冲频率。在此，脉冲频率确定剂量泵的每个时间单元上的输送量。
为了运行根据本发明的设备，构成流体输送装置的两个剂量泵分别藉由由程序控制的电控制器暂时被施加脉冲化的电流，其中该电控制器自身是该燃烧发动机的发动机控制器或与该燃烧发动机的发动机控制器处于操作性连接中，并且能够处理关于该燃烧发动机的负载和排气温度的状态信息。
在此，该电控制器以根据程序确定的方式依赖于所述的状态信息仅在如下情况下给该第一剂量泵施加脉冲化的电流：该排气温度在该排气导管中高到使得该燃料至少部分地在该喷射装置的出口处蒸发。
优选地，用于施加给第一剂量泵的脉冲化电流的频率由电控制器以根据程序确定的方式依赖于以上所提及的状态信息来确定。该频率确定每个时间单元上的输送量。
此外优选地，该电控制器被编程为：在以下情况下，即用于供应该喷射装置的该第一剂量泵由于排气温度过低而没有或仅以很低的频率被施加由脉冲激发的电流，替代于此该第二剂量泵被施加由脉冲激发的电流，以便给该燃烧装置供应燃料，其中同时，由该电控制器来激活向该燃烧装置提供来自压缩机的空气。
