Des Weiteren betrifft die Erfindung ein Verfahren zum Betreiben einer Brennkraftmaschine.Description: [0001] The invention relates to an internal combustion engine according to the preamble of claim 1. Furthermore, the invention relates to a method for operating an internal combustion engine.
[0002] Aus der Praxis sind Brennkraftmaschinen mit und ohne Abgasturboaufladung bekannt. Bei aufgeladenen Brenn-kraftmaschinen wird Abgas, welches die Zylinder der Brennkraftmaschine verlâsst, in mindestens einer Turbine entspannt, wobei hierbei gewonnene Energie in mindestens einem Verdichter genutzt wird, um den Zylindern der Brennkraftmaschine zuzuführende Ladeluft zu verdichten.From practice, internal combustion engines are known with and without Abgasturboaufladung. In supercharged internal combustion engines, exhaust gas leaving the cylinders of the internal combustion engine is expanded in at least one turbine, in which case energy obtained in at least one compressor is used to compress charge air to be supplied to the cylinders of the internal combustion engine.
[0003] Beim Starten der Brennkraftmaschine muss der Motor zunàchst hochlaufen. Hierzu wird abhàngig von der Bau-art der Brennkraftmaschine eine definierte Zeitspanne benötigt. Dabei ist es von Vorteil, wenn die zum Hochlaufen der Brennkraftmaschine benötigte Zeit möglichst kurz ist. Dies ist insbesondere bei sogenannten Offshore-Schiffen der Fall, um innerhalb kürzester Zeit die Manövrierfàhigkeit des Schiffes zu gewàhrleisten.When starting the engine, the engine must first run up. For this purpose, a defined period of time is required, depending on the type of construction of the internal combustion engine. It is advantageous if the time required to run the internal combustion engine is as short as possible. This is the case in particular with so-called offshore vessels in order to ensure the maneuverability of the ship within the shortest possible time.

This object is achieved by an internal combustion engine according to claim 1. The internal combustion engine according to the invention has at least one compressed air reservoir that can be shut off by a valve, compressed air stored in the or each compressed air reservoir being able to be run by opening the or each valve in the direction of the cylinders in order to accelerate the running-up of the internal combustion engine.
[0005] Mit der erfindungsgemàssen Brennkraftmaschine kann die zum Hochlaufen der Brennkraftmaschine benötigte Zeit minimiert werden.With the internal combustion engine according to the invention, the time required for starting up the internal combustion engine can be minimized.
[0006] Bei einer Brennkraftmaschine ohne Abgasturboaufladung ist die Druckluft in eine zu den Zylindern der Brennkraft-maschine führende Ladeluftleitung und/oder unmittelbar in die Zylinder der Brennkraftmaschine einbringbar.In an internal combustion engine without Abgasturboaufladung the compressed air is introduced into a leading to the cylinders of the internal combustion engine charge air line and / or directly into the cylinder of the internal combustion engine.
[0007] Bei einer Brennkraftmaschine mit Abgasturboaufladung ist die Druckluft zusâtzlich oder alternativ in eine zwischen einem Verdichter der Aufladungseinrichtung und einem Ladeluftkühler der Aufladungseinrichtung verlaufende Ladeluftlei-tung und/oder unmittelbar in einen Verdichter der Aufladungseinrichtung einbringbar.In an internal combustion engine with turbocharging the compressed air is additionally or alternatively in a running between a compressor of the supercharger and a charge air cooler of the supercharger Charging air supply and / or directly introduced into a compressor of the supercharger.
[0008] Das Verfahren zum Betreiben der Brennkraftmaschine ist in Anspruch 8 definiert.The method for operating the internal combustion engine is defined in claim 8.
[0009] Vorzugsweise wird gleichzeitig zum Öffnen des oder jedes Ventils des oder jedes Druckluftbehâlters eine Kraft-stoffzufuhr zur Brennkraftmaschine erhöht, um das Hochlaufen der Brennkraftmaschine zu beschleunigen.Preferably, at the same time for opening the or each valve of the or each Druckluftbeh? Lters a fuel supply to the internal combustion engine is increased to accelerate the run-up of the internal combustion engine.

Es sei an dieser Stelle darauf hingewiesen, dass beliebige Kombinationen dieser Einspeisestellen für die Druckluft genutzt werden können. So ist es möglich, die im Druckbehâlter 16 gespeicherte Druckluft an einer, an beliebigen zwei, an belie-bigen drei oder an allen vier in Fig. 5 gezeigten Einspeisestellen in die Ladeluft einzuleiten bzw. einzubringen, um dann die Druckluft zur Beschleunigung des Hochlaufens der Brennkraftmaschine 10 in Richtung auf die Zylinder 11 der Brenn-kraftmaschine 10 zu leiten.

Es ist auch möglich, mehreren Druckbehâltern 16 ein gemeinsames Ventil 17 zuzuordnen.In contrast to the embodiments shown, more than one pressure vessel 16 may be present.

It is also possible to assign a common valve 17 to a plurality of pressure vessels 16.
[0025] Zur Beschleunigung eines Hochlaufens einer Brennkraftmaschine 10 mit mehreren Zylindern 11 wird demnach Druckluft, die in mindestens einem Druckluftbehâlter 16 gespeichert ist, in Richtung auf die Zylinder 11 der Brennkraftma-schine 10 geleitet. Gleichzeitig zum Öffnen des Ventils 17 des Druckluftbehàlters 16 wird vorzugsweise eine Kraftstoffzu-fuhr zu den Zylindern 11 der Brennkraftmaschine 10 erhöht.To accelerate a run-up of an internal combustion engine 10 with a plurality of cylinders 11 is thus compressed air, which is stored in at least one Druckluftbehäll 16, directed toward the cylinder 11 of the internal combustion engine 10.
