Description
Die Erfindung betrifft einen aufgeladenen Dieselmotor nach dem Oberbegriff des Anspruchs 1.The invention relates to a supercharged diesel engine according to the Preamble of claim 1.
Aus der DE-OS 38 24 346 ist ein gattungsgemäßer aufgeladener Dieselmotor bekannt, der ein in üblicher Machart ausgebildetes gegossenes Kurbelgehäuse in V-Bauart aufweist. Auf der einen Stirnseite der Brennkraftmaschine ist ein Abgasturbolader angeordnet, der die durch einen Lader verdichtete Luft durch eine Ladeluftleitung in einen auf der gegenüberliegenden Stirnseite des Dieselmotors angeordneten Ladeluftkühler leitet. Von dem Ladeluftkühler wird die abgekühlte Ladeluft in einen Ladeluftverteilkanal entlang einer Zylinderreihe geführt. Dabei sind sowohl die Ladeluftleitung als auch der Ladeluftverteilkanal als separat hergestellte Leitungen ausgebildet, die nebeneinanderliegend in dem V-Raum des Dieselmotors angeordnet sind.DE-OS 38 24 346 is a generic supercharged Known diesel engine, which is a conventional design cast crankcase in V-type. on the one An exhaust gas turbocharger is arranged on the front side of the internal combustion engine, the air compressed by a supercharger through a charge air line in one on the opposite end of the diesel engine arranged intercooler conducts. From the charge air cooler cooled charge air in a charge air distribution duct along a Row of cylinders guided. Both the charge air line and the charge air distribution duct is designed as separately manufactured lines, the side by side in the V-space of the diesel engine are arranged.
Aus der JP 57/24417 ist ein weiterer Dieselmotor bekannt, der ebenfalls ein gegossenes V-förmig ausgebildetes Kurbelgehäuse aufweist. Dabei sind in den V-Raum Abgasturbolader angeordnet und an den Stirnseiten Ladeluftwärmetauscher befestigt. Zudem ist eine Ladeluftverteilleitung in das Kurbelgehäuse eingegossen.Another diesel engine is known from JP 57/24417 also a cast V-shaped crankcase having. Exhaust gas turbochargers are arranged in the V-space attached to the front of the charge air heat exchanger. In addition, one The charge air distribution line is cast into the crankcase.
Aufgabe der Erfindung ist es, einen aufgeladenen Dieselmotor nach dem Oberbegriff des Anspruchs 1 zu schaffen, bei dem die Leitungen vom Abgasturbolader zum Ladeluftkühler beziehungsweise von dort zu den Zylinderköpfen möglichst platzsparend und die Zugänglichkeit zu anderen Teilen nicht beeinträchtigend angebracht sind.The object of the invention is a supercharged diesel engine to provide the preamble of claim 1, in which the lines from the exhaust gas turbocharger to the charge air cooler or from there the cylinder heads as space-saving as possible and the accessibility other parts are not impaired.
Diese Aufgabe wird entsprechend dem kennzeichnenden Teil des Anspruchs 1 gelöst.This task is performed according to the characteristic part of the Claim 1 solved.
Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen. Further refinements of the invention are as follows Description and the dependent claims.
Die Erfindung wird nachstehend anhand eines in den beigefügten Abbildungen dargestellten Ausführungsbeispiels näher erläutert.The invention is illustrated below with the aid of one of the following Illustrated embodiment illustrated.
Fig. 1 zeigt schematisch ein Kurbelgehäuse eines Dieselmotors mit Abgasturbolader und Ladeluftkühler sowie die Luftführung hierbei entsprechend einem Schnitt in Längsrichtung der Kurbelwelle. Fig. 1 shows schematically a crankcase of a diesel engine with exhaust gas turbocharger and charge air cooler and the air flow here in accordance with a section in the longitudinal direction of the crankshaft.
Fig. 2 zeigt schematisch einen Schnitt des Dieselmotors von Fig. 1 senkrecht zur Längsachse der Kurbelwelle. Fig. 2 shows schematically a section of the diesel engine of Fig. 1 perpendicular to the longitudinal axis of the crankshaft.
Der dargestellte aufgeladene Dieselmotor umfaßt ein Kurbelgehäuse 1 mit einem Lagerdeckel 2 zur Aufnahme einer Kurbelwelle 3 und zwei Reihen von V-förmig zueinander angeordneten Zylindern 4, deren Kolben über nicht dargestellte Kurbeln die Kurbelwelle 3 in Drehung versetzen und deren Abgase einem Abgasturbolader 5 zum Aufladen von Ladeluft zugeführt werden. Der zwischen den beiden Zylinderreihen ausgebildete (im Schnitt V-förmige, siehe Fig. 2) V-Raum des Kurbelgehäuses 1 ist in einem untenliegenden (innenliegenden) Kanal 6 und einem obenliegenden (außenliegenden) Kanal 7 unterteilt. Der untenliegende Kanal 6 verbindet den Abgasturbolader 5 an einer Stirnseite des Kurbelgehäuses 1 mit einem Ladeluftkühler 8 an der anderen Stirnseite des Kurbelgehäuses 1. Hierbei sind an den Stirnseiten des Kurbelgehäuses 1 Konsolen 9 für den Abgasturbolader 5 und den Ladeluftkühler 8 vorgesehen, die jeweils eine Luftführung 10 vom beziehungsweise in den untenliegenden Kanal 6 aufweisen.The supercharged diesel engine shown comprises a crankcase 1 with a bearing cover 2 for receiving a crankshaft 3 and two rows of cylinders 4 arranged in a V-shape relative to one another, the pistons of which set the crankshaft 3 in rotation via cranks (not shown ) and the exhaust gases of which are used to charge an exhaust gas turbocharger 5 Charge air are supplied. The V space of the crankcase 1, which is formed between the two rows of cylinders (V-shaped in section, see FIG. 2), is subdivided into an underlying (internal) channel 6 and an upper (external) channel 7 . The channel 6 located below connects the exhaust gas turbocharger 5 on one end face of the crankcase 1 to a charge air cooler 8 on the other end face of the crankcase 1 . In this case, consoles 9 for the exhaust gas turbocharger 5 and the charge air cooler 8 are provided on the end faces of the crankcase 1 , each of which has an air duct 10 from or into the duct 6 below.
Der oben liegende Kanal 7 stellt den Verteilkanal für Ladeluft zu den Zylinderköpfen 11 der Zylinder 4 dar und ist über einen Rohrabschnitt 12 mit dem Ladeluftkühler 8 und über Austrittsöffnungen 13 mit den Zylinderköpfen 11 verbunden. Der Kanal 7 kann zwar (ebenso wie der untenliegende Kanal 6 zum Verbinden eines Abgasturboladers 5 für eine Zylinderreihe mit einem zugehörigen Ladeluftkühler 8) zum Verbinden eines von zwei Ladeluftkühlern 8 mit jeweils nur einer Reihe von Zylinderköpfen 11 in Längsrichtung unterteilt sein, jedoch wird ein einheitlicher Verteilkanal 7, der zu allen Zylinderköpfen 11 führt, bevorzugt.The channel 7 located at the top represents the distribution channel for charge air to the cylinder heads 11 of the cylinders 4 and is connected to the charge air cooler 8 via a pipe section 12 and to the cylinder heads 11 via outlet openings 13 . The channel 7 may (like the channel 6 below for connecting an exhaust gas turbocharger 5 for a cylinder bank with an associated intercooler 8 ) for connecting one of two intercoolers 8 with only one row of cylinder heads 11 each be divided in the longitudinal direction, but a more uniform one Distribution channel 7 , which leads to all cylinder heads 11 , preferred.
Das Kurbelgehäuse 1 hat zweckmäßig an beiden Stirnseiten gleiche Anschlußflächen für die Konsolen 9, so daß Ladeluftkühler 8 und Abgasturbolader 5 vertauschbar sind. Hierbei sind an beiden Enden des Kanals 7 Anschlußflansche 14 für den Rohrabschnitt 12 vorgesehen, von denen einer verdeckelt ist.The crankcase 1 expediently has the same connection surfaces for the brackets 9 on both end faces, so that the charge air cooler 8 and the exhaust gas turbocharger 5 are interchangeable. Here, 7 connecting flanges 14 for the pipe section 12 are provided at both ends of the channel, one of which is capped.
Auf diese Weise wird der V-Raum des Kurbelgehäuses 1 zweckmäßig genutzt und es werden Verbindungsleitungen an der Außenseite des Motors, die zu entsprechenden Aufbauten führen und den Zugang zu anderen Teilen beeinträchtigen können, vermieden.In this way, the V-space of the crankcase 1 is used expediently and connecting lines on the outside of the engine, which lead to corresponding structures and can impair access to other parts, are avoided.
