Description
Die Erfindung betrifft eine Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The The invention relates to an internal combustion engine according to the preamble of claim 1.
Aus
der Offenlegungsschrift
Aufgabe der Erfindung ist es demgegenüber, eine Kühlung des Abgases in bestimmten Betriebspunkten der Brennkraftmaschine zu unterbinden.task the invention it is in contrast, a cooling the exhaust gas in certain operating points of the internal combustion engine to prevent.
Diese Aufgabe wird durch eine Brennkraftmaschine mit den Merkmalen des Anspruchs 1 gelöst.These Task is by an internal combustion engine with the characteristics of Claim 1 solved.
Die erfindungsgemäße Brennkraftmaschine zeichnet sich durch ein Ventil aus, das den Kühlmitteldurchfluss durch den Abgas/Kühlmittelwärmetauscher temperaturabhängig steuert. Je nach Schaltzustand des Ventils ist der Abgas/Kühlmittelwärmetauscher mit Kühlmittel durchströmt oder nicht durchströmt. Das Ventil ist in den Kühlmittelleitungen oder in dem Gehäuse des Abgas/Kühlmittelwärmetauscher anordenbar. Das Ventil schaltet ab einer vorbestimmbaren Kühlmitteltemperatur.The inventive internal combustion engine records through a valve that the coolant flow through the Exhaust gas / coolant heat exchanger temperature-dependent controls. Depending on the switching state of the valve is the exhaust / coolant heat exchanger with coolant flows through or not flowed through. The valve is in the coolant lines or in the housing the exhaust / coolant heat exchanger arranged. The valve switches from a predeterminable coolant temperature.
In Ausgestaltung der Erfindung ist das Ventil als 3/2-Wegeventil ausgeführt. Bei einer Kühlmitteltemperatur unterhalb des Schaltpunktes des 3/2-Wegeventils ist der Abgas/Kühlmittelwärmetauscher nicht mit Kühlmittel durchströmt.In Embodiment of the invention, the valve is designed as a 3/2-way valve. at a coolant temperature below the switching point of the 3/2-way valve, the exhaust gas / coolant heat exchanger is not with coolant flows through.
Ab einer vorbestimmbaren Temperatur schaltet das 3/2-Wegeventil den Abgas/Kühlmittelwärmetauscher in den Kühlmittelstrom ein.From a pre-definable temperature, the 3/2-way valve switches Exhaust gas / coolant heat exchanger in the coolant flow one.
In weiterer Ausgestaltung der Erfindung ist das Ventil als Schaltventil ausgeführt. Das Schaltventil sperrt den Durchfluss durch den Abgas/Kühlmittelwärmetauscher. Ab einer bestimmten Kühlmitteltemperatur öffnet das Schaltventil, so dass der Abgas/Kühlmittelwärmetauscher parallel zum Kühlmittelstrom geschaltet ist.In Another embodiment of the invention, the valve is a switching valve executed. The switching valve blocks the flow through the exhaust gas / coolant heat exchanger. From a certain coolant temperature opens Switching valve, allowing the exhaust gas / coolant heat exchanger parallel to the coolant flow is switched.
In weiterer Ausgestaltung der Erfindung ist das Ventil als selbstschaltendes Thermostatventil ausgeführt. Selbstschaltende Ventile weisen eine Bimetallfeder, eine Wachspatrone oder ein temperatursensitives Element wie z.B. eine Memory-Feder auf.In Another embodiment of the invention, the valve is self-switching Thermostatic valve executed. Self-switching valves have a bimetallic spring, a wax cartridge or a temperature sensitive element such as e.g. a memory pen on.
In weiterer Ausgestaltung der Erfindung bildet das Ventil mit dem Abgas/Kühlmittel Wärmetauscher eine Baueinheit. In einer vorteilhaften Ausführungsform ist das Ventil in dem Gehäuse des Abgas/Kühlmittelwärmetauschers integriert. Der Abgas/Kühlmittelwärmetauscher und das Ventil ist komplett vormontierbar. Damit ist eine einfache Montage gewährleistet. Durch den Entfall einer Kühlmittelleitung zwischen Abgas/Kühlmittelwärmetauscher und Ventil sowie durch Entfall eines eigenständigen Gehäuses für das Ventil ist diese Ausführungsform eine bauraumsparende Lösung.In Further embodiment of the invention forms the valve with the exhaust gas / coolant heat exchangers a structural unit. In an advantageous embodiment, the valve is in the housing of the exhaust gas / coolant heat exchanger integrated. The exhaust gas / coolant heat exchanger and the valve is completely pre-assembled. This is a simple one Assembly guaranteed. By the omission of a coolant line between exhaust / coolant heat exchanger and valve and by omission of a separate housing for the valve is this embodiment a space-saving solution.
In weiterer Ausgestaltung der Erfindung verbleibt das Ventil bei Versagen einer Schaltvorrichtung in einer Offenstellung. Das Ventil ist so ausgelegt, dass bei Versagen der Schaltvorrichtung, die z.B. als Elektromagnet oder als Wachspatrone ausgebildet ist, der Abgas/Kühlmittelwärmetauscher grundsätzlich mit Kühlmittel durchströmt ist. Mit dieser Auslegung ist gewährleistet, dass die Abgasemissionen der Brennkraftmaschine bei Ventilversagen nicht ansteigen.In In another embodiment of the invention, the valve remains in case of failure a switching device in an open position. The valve is like that designed so that in case of failure of the switching device, the e.g. as electromagnet or formed as a wax cartridge, the exhaust gas / coolant heat exchanger in principle with coolant flows through is. This design ensures that the exhaust emissions of the Internal combustion engine does not rise in case of valve failure.

Neben der Vermeidung der Verlackung, führt ein Unterbleiben der Kühlung des rückgeführten Abgases, insbesondere nach einem Kaltstart, zu höheren Verbrennungstemperaturen bzw. höheren Abgastemperaturen. Die nachgeordneten Abgasreinigungskomponenten wie Katalysator oder Dieselpartikelfilter kommen schneller auf Betriebstemperatur, so dass eine Abgasreinigung früher einsetzt.In addition to avoiding laking, failure to cool the recirculated Ab gases, in particular after a cold start, to higher combustion temperatures or higher exhaust gas temperatures. The downstream exhaust gas cleaning components such as catalytic converter or diesel particulate filter come to operating temperature faster, so that an exhaust gas purification starts earlier.
