Abstract
Die Erfindung betrifft ein Verfahren bzw. eine Vorrichtung zur Kühlung von Verbrennungsluft bei einem Kraftfahrzeug mit einer Brennkraftmaschine (2) und mit einer Klimaanlage mit einem Verdampfer (7), der über eine Saugleitung (8, 8.1) und eine Druckleitung (9) mit einem Verdichter in einem Kühlmittelkreislauf verbunden ist, wobei mittels eines im Verbrennungsluft-Ansaugbereich (3) der Brennkraftmaschine (2) angeordnetes Umschaltventil (5) Verbrennungsluft durch den Verdampfer (7) der Kraftfahrzeug-Klimaanlage leitbar ist.The invention relates to a method and a device for cooling combustion air in a motor vehicle with an internal combustion engine (2) and with an air conditioner with an evaporator (7) via a suction line (8, 8.1) and a pressure line (9) with a Compressor is connected in a coolant circuit, wherein by means of a in the combustion air intake region (3) of the internal combustion engine (2) arranged switching valve (5) combustion air through the evaporator (7) of the motor vehicle air conditioning is conductive.
Description
Die Erfindung betrifft ein Verfahren zur Kühlung der Verbrennungsluft bei einem Kraftfahrzeug mit einer Brennkraftmaschine und mit einer Klimaanlage mit einem Verdampfer, der über eine Saugleitung und eine Druckleitung mit einem Verdichter in einem Kühlmittelkreislauf verbunden ist. The invention relates to a method for cooling the combustion air in a motor vehicle with an internal combustion engine and with an air conditioner with an evaporator, which is connected via a suction line and a pressure line to a compressor in a coolant circuit.
Bei Brennkraftmaschinen kann es bei warmen Umgebungsbedingungen zu einer unerwünschten Aufheizung der Ansauganlage bzw. der zur Gemischbildung notwendingen Verbrennungsluft kommen. Bei geringem Luftdurchsatz kann das unter Umständen zu einem Zusammenbruch der Leistung (hohe Ansaugluftdichte, sogenannte klopfende Verbrennung durch Selbstentzündung des Kraftstoffs bei Benzinmotoren) führen. In internal combustion engines, undesired heating of the intake system or the combustion air necessary for mixture formation may occur under warm ambient conditions. At low air flow rates, this can lead to a breakdown in performance (high intake air density, so-called knocking combustion due to spontaneous combustion of the fuel in petrol engines).

Der Erfindung liegt die Aufgabe zu Grunde, eine besonders einfache, bei Bedarf aber höchst wirkungsvolle Lösung der angesprochenen Probleme anzubieten. The invention is based on the object to offer a particularly simple, if necessary, but highly effective solution of the problems addressed.
Dazu wird vorgeschlagen, bei einem Kraftfahrzeug mit einer Brennkraftmaschine und mit einer Klimaanlage mit einem Verdampfer, der über eine Saugleitung und eine Druckleitung mit einem Verdichter in einem Kühlmittelkreislauf verbunden ist, über ein im Verbrennungsluftansaugbereich der Brennkraftmaschine anordenbares Umschaltventil Verbrennungsluft zur Abkühlung durch den Verdampfer der Klimaanlage zu leiten. Vorzugsweise wird das Umschaltventil, das z.B. bei Saugmotoren vor der Drosselklappe im Ansaugbereich platziert sein kann, über das Motorsteuergerät bzw. über die zentrale Steuereinheit des Kraftfahrzeuges in Abhängigkeit von der Temperatur im Ansaugbereich geschaltet. For this purpose, it is proposed in a motor vehicle with an internal combustion engine and with an air conditioner with an evaporator, which is connected via a suction line and a pressure line with a compressor in a coolant circuit, via an arrangeable combustion air intake of the engine switching valve combustion air for cooling by the evaporator of the air conditioner to lead. Preferably, the switching valve, e.g. may be placed in the intake in front of the throttle in naturally aspirated engines, switched via the engine control unit or via the central control unit of the motor vehicle depending on the temperature in the intake.
Zum Schutz des Verdampfers bzw. um zu vermeiden, dass das Kühlmittel im Kältekreislauf der Klimaanlage zu stark überhitzt, kann der Verdampfer mit einer in Abhängigkeit von der Kältemitteltemperatur im Kühlkreislauf der Klimaanlage Ventil-geregelten By-Pass-Leitung ausgestattet sein. Auch dieses Ventil zur Vorbeileitung der Verbrennungsluft am Verdampfer über den By-Pass kann über das Motorsteuergerät bzw. über die zentrale Steuereinheit schaltbar sein. To protect the evaporator or to prevent the coolant in the refrigeration cycle of the air conditioning system from overheating too much, the evaporator can be equipped with a valve-controlled by-pass line depending on the refrigerant temperature in the cooling circuit of the air conditioning system. This valve for bypassing the combustion air at the evaporator via the by-pass can also be switched via the engine control unit or via the central control unit.
Für den Fachmann sind die großen Vorteile dieser erfinderischen Lösung leicht erkennbar. Durch die Kühlung der Ansaugluft bzw. das Verhindern einer Aufheizung der Ansauganlage ist eine optimierte Leistungsabgabe der Brennkraftmaschine sicherzustellen. Durch kühlere Ansaugluft ist ggf. zusätzlich eine Effizienzsteigerung der Brennkraftmaschine erreichbar. Unerwünschte Begleiterscheinungen beim Betrieb der Brennkraftmaschine, wie z.B. Selbstentzündung des Brennstoffs = „Klopfen“ können wirkungsvoll verhindert werden. Those skilled in the art will readily appreciate the great advantages of this inventive solution. By cooling the intake air or preventing heating of the intake system, an optimized power output of the internal combustion engine is to be ensured. By cooler intake air, an increase in efficiency of the internal combustion engine is possibly additionally achievable. Undesirable effects in the operation of the internal combustion engine, such. Self-ignition of the fuel = "knocking" can be effectively prevented.
