Abstract

本发明涉及一个内燃机，具有一个用于将燃料喷射到内燃机燃烧室里面的共轨喷射***，具有用于将燃料从燃料箱(11)输送到轨(10)的第一燃料输送路径(12)，其中在燃料箱与轨之间的第一燃料输送路径里面连接一个低压泵(13)和一个高压泵(14)，并且具有一个连接在同样导引到轨的第二燃料输送路径(16)里面的用于以给定的内燃机运行方式、尤其是在内燃机起动之前提高在轨中存在的压力的装置(15)。按照本发明在轨(10)与附加燃料箱(17)之间的第二燃料输送路径(16)里面连接用于提高在轨中存在的压力的装置(15)。

Description

内燃机
技术领域
本发明涉及一种如权利要求1或2前序部分所述的内燃机。
背景技术
由DE10155381A1已知一个具有通用轨(rail)单喷射***的内燃机。燃料通过第一燃料输送路径输送到所谓的单喷射***轨，其中第一燃料输送路径在轨与燃料箱之间延伸，并且在第一燃料输送路径中连接一个低压泵以及一个高压泵。按照DE10155381A1在那里公开的内燃机还包括一个用于以给定的内燃机运行方式提高在轨中存在的压力的装置，其中用于提高在轨中存在的压力的装置连接在同样导引到轨的第二燃料输送路径里面。第二燃料输送路径平行于第一燃料输送路径延伸，即，两个燃料输送路径在同一燃料箱上产生并导引到同一轨。
发明内容
由此本发明的目的是，提供新型的内燃机。
按照本发明的第一方面这个问题通过如权利要求1所述的内燃机得以实现。据此用于提高在轨中存在的压力的装置接到在轨与附加燃料箱之间的第二燃料输送路径上。
当内燃机以重油驱动的时候，本发明的第一方面尤其是有利的，其中第一燃料输送路径用于将重油输送到内燃机的轨。在这种情况下最好在附加燃料箱中提供柴油，由此对于接有用于提高在轨中存在的压力的装置的第二燃料路径无需加热装置。
按照本发明的第二方面这个问题通过如权利要求2所述的内燃机得以实现。据此用于提高在轨中存在的压力的装置连接到在轨与低压泵之间的第二燃料输送路径中，从而从第一燃料输送路径在低压泵与高压泵之间分支出第二燃料输送路径。
本发明的第二方面尤其对于以柴油驱动的内燃机是有利的，其中对于第一燃料输送路径和第二燃料输送路径都无需加热装置。
由从属权利要求和下面的描述给出本发明的优选改进方案。借助于附图详细描述本发明的一个实施例，但是不局限于此。
附图说明
附图中：
图1以十分简化的方框图示出按照本发明第一实施例的按照本发明的内燃机，
图2以十分简化的方框图示出按照本发明第二实施例的按照本发明的内燃机。
具体实施方式
本发明涉及内燃机，其具有一个用于将燃料喷射到内燃机燃烧室里面的共轨喷射***。
在图1中所示的本发明第一实施例中按照本发明的内燃机的共轨喷射***包括一个轨10，其中可以将在燃料箱11中提供的燃料通过第一燃料输送路径输送到轨10，即通过组合在第一燃料输送路径12中的低压泵13以及高压泵14。
按照图1该内燃机包括一个用于以给定的内燃机运行方式、尤其是在起动内燃机之前提高在轨10中存在的压力的装置15，其中将该装置15组合到同样导引到轨10的第二燃料输送路径16里面。按照图1第二燃料输送路径16在轨10与附加燃料箱17之间延伸。
在图1中示出的按照本发明的内燃机方案如果内燃机以重油驱动尤其具有优点。在也称为初级燃料箱的燃料箱11中提供燃料重油。而在也称为次级燃料箱的附加燃料箱17中在这种情况下最好提供柴油作为燃料，由此对于第二燃料输送路径16无需加热装置。
图2示出按照本发明的第二实施例的内燃机方案，其中按照图2的方案该内燃机也包括一个共轨喷射***，其中仍然可以通过第一燃料输送路径20将燃料箱19中提供的燃料输送到一个轨18，在该输送路径中连接一个低压泵21以及一个高压泵22。
与图1的内燃机一样按照图2的内燃机同样具有一个用于以给定的内燃机运行方式提高在轨18中存在的压力的装置23，其中该装置23仍然连接在第二燃料输送路径24里面。在按照图2的实施例中第二燃料输送路径24从第一燃料输送路径20在低压泵21与高压泵22之间分支出，因此用于提高在轨中存在的压力的装置23连接在轨18与低压泵21之间。
按照图2的内燃机方案尤其在以柴油驱动内燃机时具有优点，如果在唯一的燃料箱19中提供柴油燃料的话。但是图2的方案也可以用于以重油驱动的内燃机。
用于提高在轨中存在的压力的装置最好是一个伺服单元，如同已由DE10155381A1已知的那样。
