Description
Die Erfindung betrifft eine Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to an internal combustion engine according to the preamble of claim 1.
Aus der
Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine Korrosion und Verschmutzung in einer Leitung der Brennkraftmaschine zu verringern und dadurch insbesondere vorteilhaft eine Lebensdauer der Brennkraftmaschine zu verlängern. Sie wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 gelöst. Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.The invention is in particular the object of reducing corrosion and contamination in a line of the internal combustion engine and thereby particularly advantageous to extend a life of the internal combustion engine. It is achieved according to the invention by the features of claim 1. Further embodiments emerge from the subclaims.
Die Erfindung geht aus von einer Brennkraftmaschine für ein Kraftfahrzeug, mit zumindest einem Brennraum und mit zumindest einer mit dem Brennraum strömungstechnisch verbundenen Leitung, die dazu vorgesehen ist, ein durch eine Kühlvorrichtung gekühltes, für eine Verbrennung bestimmtes Gas zu leiten.The invention relates to an internal combustion engine for a motor vehicle, having at least one combustion chamber and at least one fluidically connected to the combustion chamber line, which is intended to conduct a cooled by a cooling device, intended for combustion gas.
Es wird vorgeschlagen, dass die Brennkraftmaschine zumindest eine Heizvorrichtung umfasst, die dazu vorgesehen ist, eine Temperatur der zumindest einen Leitung oberhalb einer Kondensationstemperatur des zu leitenden Gases zu halten. Dadurch kann vorteilhaft eine Kondensation des zu leitenden Gases verhindert werden, wodurch insbesondere eine Korrosion und Verschmutzung in der zumindest einen Leitung zumindest wesentlich verringert werden kann. Unter einer „Leitung” soll insbesondere ein Element verstanden werden, das für einen Transport bzw. eine Leitung von Fluiden in seinem Inneren vorgesehen ist, wobei ein Durchmesser eines Strömungsquerschnitts der Leitung wesentlich, vorteilhafterweise zumindest um den Faktor 10, kleiner ist als eine Länge der Leitung. Unter „vorgesehen” soll insbesondere speziell programmiert, ausgelegt und/oder ausgestattet verstanden werden. Unter einer „Kühlvorrichtung” soll insbesondere eine Vorrichtung verstanden werden, die dazu vorgesehen ist, einem zu kühlenden Medium eine Wärmeenergie zu entziehen und einem Kühlmittel zuzuführen. Die Kühlvorrichtung ist dabei vorzugsweise als eine Abgaskühler oder ein Ladeluftkühler ausgebildet. Grundsätzlich ist es natürlich auch denkbar, dass der Kühler als ein anderer, dem Fachmann als sinnvoll erscheinender Kühler ausgebildet ist. Unter einem „für eine Verbrennung bestimmten Gas” soll insbesondere ein Fluid verstanden werden, das zum Betrieb der Brennkraftmaschine in einen Brennraum der Brennkraftmaschine geleitet wird um dort mittels einer dem Fachmann als sinnvoll erscheinenden Methode gezündet zu werden. Dabei ist das für eine Verbrennung bestimmte Gas vorteilhafterweise als eine Ladeluft und/oder ein Abgas ausgebildet. Unter einer „Ladeluft” soll dabei insbesondere eine für eine Verbrennung in der Brennkraftmaschine benötigte Frischluft verstanden werden, die aus einer Umgebung angesaugt wird. Unter einem „Abgas” soll insbesondere ein nach der Verbrennung in dem Brennraum der Brennkraftmaschine befindliches, durch die Verbrennung entstandenes Gas verstanden werden. Unter einer „Temperatur der Leitung” soll insbesondere eine Temperatur der Bereiche der Leitung verstanden werden, die mit dem zu führenden Gas in Kontakt stehen, also insbesondere eine Temperatur einer Innenwandung der Leitung verstanden werden. Unter einer „Kondensationstemperatur” soll insbesondere eine Temperatur verstanden werden, bei der ein Stoff bei einem gegebenen Druck kondensiert, also von einem gasförmigen in einen flüssigen Aggregatzustand übergeht. Die Kondensationstemperatur ist stoffspezifisch und abhängig vom Druck.It is proposed that the internal combustion engine comprises at least one heating device which is provided to keep a temperature of the at least one line above a condensation temperature of the gas to be conducted. This advantageously prevents condensation of the gas to be conducted, as a result of which, in particular, corrosion and contamination in the at least one line can be at least substantially reduced. A "line" is to be understood in particular an element which is provided for a transport or a conduit of fluids in its interior, wherein a diameter of a flow cross-section of the conduit substantially, advantageously at least by a factor of 10, is smaller than a length of Management. By "provided" is intended to be understood in particular specially programmed, designed and / or equipped. A "cooling device" is to be understood in particular to mean a device which is intended to remove a thermal energy from a medium to be cooled and to supply it to a coolant. The cooling device is preferably designed as an exhaust gas cooler or a charge air cooler. In principle, it is of course also conceivable that the cooler is designed as another cooler which appears appropriate to the person skilled in the art. A "gas intended for combustion" is to be understood as meaning, in particular, a fluid which is conducted into a combustion chamber of the internal combustion engine for operation of the internal combustion engine in order to be ignited there by means of a method that appears appropriate to a person skilled in the art. In this case, the gas intended for combustion is advantageously designed as a charge air and / or an exhaust gas. A "charge air" is to be understood in particular as meaning a fresh air required for combustion in the internal combustion engine, which is sucked in from an environment. An "exhaust gas" is to be understood as meaning, in particular, a gas produced by combustion after combustion in the combustion chamber of the internal combustion engine. A "temperature of the line" is to be understood in particular to mean a temperature of the areas of the line which are in contact with the gas to be passed, that is to say in particular a temperature of an inner wall of the line. A "condensation temperature" is to be understood in particular as meaning a temperature at which a substance condenses at a given pressure, that is to say from a gaseous to a liquid state of matter. The condensation temperature is substance-specific and depends on the pressure.
Des Weiteren wird vorgeschlagen, dass die Heizvorrichtung zumindest ein elektrisches Heizelement umfasst, das fest mit der Leitung verbunden ist. Dadurch kann die Heizvorrichtung besonders vorteilhaft und einfach ausgebildet werden. Unter einem „elektrischen Heizelement” soll dabei insbesondere ein Element verstanden werden, dass eine elektrische Energie in eine Wärmeenergie umwandelt. Dabei ist das elektrische Heizelement vorzugsweise als eine elektrische Heizspirale ausgebildet, die einen Heizdraht umfasst, der sich bei einem an die Heizspirale angelegten Strom erhitzt. Grundsätzlich ist es auch denkbar, dass das elektrische Heizelement als ein anderes, dem Fachmann als sinnvoll erscheinendes Heizelement ausgebildet ist, wie beispielsweise als ein Heizwiderstand. Unter „fest mit der Leitung verbunden” soll insbesondere verstanden werden, dass das elektrische Heizelement fest und verliersicher, durch eine dem Fachmann als sinnvoll erscheinende Verbindungsart, wie beispielsweise über einen Form-, Kraft und/oder Stoffschluss, mit der Leitung verbunden ist. Vorzugsweise ist das zumindest eine Heizelement dabei an die Leitung angelötet oder während einer Herstellung der Leitung mit in die Leitung eingegossen.Furthermore, it is proposed that the heating device comprises at least one electrical heating element which is firmly connected to the line. Thereby, the heater can be formed particularly advantageous and easy. An "electric heating element" is to be understood in particular as an element that converts electrical energy into heat energy. In this case, the electrical heating element is preferably designed as an electric heating coil, which comprises a heating wire which heats when a current applied to the heating coil. In principle, it is also conceivable that the electrical heating element is designed as another heating element which appears expedient to the person skilled in the art, for example as a heating resistor. By "firmly connected to the line" is to be understood in particular that the electric heating element is fixed and captive, connected by a person skilled in the sense appearing connection, such as a form, force and / or material connection with the line. In this case, the at least one heating element is preferably soldered to the line or cast into the line during production of the line.
Ferner wird vorgeschlagen, dass das zumindest eine elektrische Heizelement der Heizvorrichtung korrosionsbeständig ausgebildet ist. Dadurch kann das Heizelement besonders robust und vorteilhaft ausgebildet werden.It is also proposed that the at least one electrical heating element of the heating device is formed corrosion-resistant. As a result, the heating element can be made particularly robust and advantageous.
Zudem wird vorgeschlagen, dass die Brennkraftmaschine eine Steuer- und/oder Regeleinheit umfasst, die dazu vorgesehen ist, die zumindest eine Heizvorrichtung zu steuern oder zu regeln. Dadurch kann eine Temperatur der Innenwandung der zumindest einen Leitung vorteilhaft besonders gut auf verschiedene Umwelt und Verfahrenseinflüsse eingestellt werden. Unter einer ”Steuer- und/oder Regeleinheit” soll insbesondere eine Einheit mit zumindest einem Steuergerät verstanden werden. Unter einem ”Steuergerät” soll insbesondere eine Einheit mit einer Prozessoreinheit und mit einer Speichereinheit sowie mit einem in der Speichereinheit gespeicherten Betriebsprogramm verstanden werden. Grundsätzlich kann die Steuer- und/oder Regeleinheit mehrere untereinander verbundene Steuergeräte aufweisen, die vorzugsweise dazu vorgesehen sind, über ein Bus-System, wie insbesondere ein CAN-Bus-System, miteinander zu kommunizieren.In addition, it is proposed that the internal combustion engine comprises a control and / or regulating unit which is provided to control or regulate the at least one heating device. As a result, a temperature of the inner wall of the at least one line can advantageously be adjusted particularly well to different environments and process influences. A "control and / or regulating unit" is to be understood in particular as a unit having at least one control unit. A "control unit" is to be understood in particular as meaning a unit having a processor unit and a memory unit as well as an operating program stored in the memory unit. In principle, the control and / or regulating unit can have a plurality of interconnected control units, which are preferably provided to communicate with one another via a bus system, in particular a CAN bus system.
