Durch die erfindungsgemäße Anordnung von zwei hadeluftkühlern zwischen den v-förmig angeordneten Zylinderreihen erreicht man eine kompakte Bauweise, ohne daß die Zugänglichkeit zur Brennstoffeinspritzpumpe beeinträchtigt wird. Es ist außerdem günstig, daß entsprechend den zulässigen Widerständen, der Kühlluftweg kurz und der Ladeluftweg durch die Iadeluftkühler lang sind. In Ausgestaltung der Erfindung wird ferner vorgeschlagen, daß eine Stirnseite der hadeluftkühler auf einer ebenen Fläche des Räderkastens abgestützt ist, wodurch ein stabiler Fixpunkt für die Befestigung der hadeluftkühler geschaffen wurde. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.The invention is based on the object of a reciprocating internal combustion engine to create with good use of space, while maintaining the accessibility of each To ensure auxiliary facilities. It is achieved according to the invention in that at the the end face of the reciprocating internal combustion engine opposite the cooling air fan a charging fan is provided for each cylinder row, each with a flat, twisted along the corresponding cylinder row horizontally running intercooler is, the Iiadeluftkühler lying between the cylinder rows V-shaped Limit the space at the top and stand apart in the middle so far that the injection pump through the opening that can be closed with a cover plate is accessible. The inventive arrangement of two hadeluftkühlern between A compact design can be achieved without the V-shaped rows of cylinders that the accessibility to the fuel injection pump is impaired. It is In addition, it is advantageous that the cooling air path corresponds to the permissible resistances short and the charge air path through the air cooler are long. In the development of the Invention is also proposed that an end face of the hadeluftkühler on is supported on a flat surface of the gear case, creating a stable fixed point for the attachment of the hadeluftkühler was created. In the drawing is a Embodiment of the invention shown.

In dem von den Zylinderreihen 1 und-2 begrenzten V-förmigen Raum ist eine Brennstoffeinspritzpumpe 4 vorgesehen. Sie wird von einem Räderkasten 5 aus angetrieben, der sich an einer Stirnseite der Hubkolbenbrennkraftmaschine befindet und die Getrieberäder für die Hilfs- und Steuerantriebe enthält. An der gegenüberliegenden Stirnseite der Hubkolbenbrennkraftmaschine ist ein axiales Kühlluftgebläse 6 angeordnet. Der von den Zylinderreihen 1 und 2 gebildete V-förmige Raum wird nach oben hin von zwei hadeluftkühlern 7 und 8 begrenzt, die längs der Zylinderreihen verlaufen und in der Mitte so weit voneinander abstehen, daB die Brennstoffeinspritzpumpe durch die Öffnung leicht zugänglich ist. Mit einem Abdeckblech 9 ist diese Öffnung und der von den Ladeluftkühlern 7 und 8 nicht abgedeckte Teil des V-förmigen Raumes verschlossen. Die Ladeluft wird von zwei Ladegebläsen 12 und 13 erzeugt, die symmetrisch zur Längsmittelebene der Brennkraftmaschine liegen und sich an der gleichen Stirnseite befinden, an der auch der Räderkasten 5 angeordnet iÜ. Während die Kühlluft durch das Kühlluftgebläse 6 in Iängsrichtung der Hubkolbenbrennkraftmaschine in den V-förmigen Raum eingeblasen wird und seitlich zwischen den Kühlrippen der Zylinder hindurch bzw. durch die Kühlluftkanäle der hadeluftkühler austritt, wird die Ladeluft von den Ladegebläsen 12 und 13 der Abgasturbolader 10 und 11 durch die Ladeluftkühler 7,8 und die Luftsammelleitunen 2_1,22, auf deren Ladeluftkühler 7,8 durch Ladeluftaustrittskrümmer 19,20 abgestützt aind, in die Zylinder gefördert.Fig. 2 shows a cross section through an internal combustion engine Fig. 1 according to section line II-II in Fig. 1.
