Description

Regelvorrichtung für die Temperatur der Ansaugeluft bei Brennkraftmaschinen Gegenstand der Erfindung ist eine Vorrichtung zur selbsttätigen Regelung der Temperatur der Ansaugeluft bei Brennkraftmaschinen. Eine einwandfreie Verbrennung und ein sparsamer Verbrauch bedingen, daß die Temperatur der Ansaugeluft innerhalb gewisser Grenzen bleibt.Control device for the temperature of the intake air in internal combustion engines The invention relates to a device for automatically regulating the temperature the intake air in internal combustion engines. Perfect combustion and an economical one Consumption require that the temperature of the intake air is within certain limits remain.

Es war nun bekannt, die Temperatur der Ansaugeluft dadurch zu regeln, daß sie aus kalter, zweckmäßig aus der freienAtmosphäre angesaugter Luft und aus warmer, beispielsweise innerhalb der Motorhaube angesaugter Luft gemischt wird. Es war auch bekannt, das Mischungsverhältnis von warmer und kalter Luft durch einenTherrnostat zu regeln.It was now known to regulate the temperature of the intake air by that they are made of cold air, suitably drawn in from the free atmosphere, and out warm air, for example sucked in inside the engine hood, is mixed. It was also known the mixing ratio of warm and cold air by a thernostat to regulate.

Nach der Erfindung wird nun eine besonders einfache, vorteilhafte Regelungsvorrichtung dadurch geschaffen, daß man den oder die Luftregelkörper an einen bereits vorhandenen, zum Einstellen der Kühlerverschlußklappen am Kühler angeordneten Thermostaten anschließt, der diese Klappen im Sinne einer annähernd gleichbleibenden Kühlwassertemperatur verstellen helfen soll.According to the invention is now a particularly simple, advantageous Control device created in that one or the air control body on an already existing one arranged on the radiator to adjust the radiator flaps Thermostat connects these flaps in the sense of an approximately constant Adjusting the cooling water temperature should help.

Auf der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung dargestellt. Der Motor i ist von der Motorhaube :2 umgeben. Um die Lufttemperaturregelung wirksam durchführen zu können, ist der Motorraum nach unten abgeschlossen, beispielsweise durch die Blechplatte 1z. Die Ansaugeleitung ist auf der Vergaserseite angeordnet. Die warme Luft wird mit dem Rohr 13 unmittelbar aus dem Raum innerhalb der Motorhaube angesaugt, die kalte Luft mit dem Rohr 1q. aus der freien Atmosphäre. An der Stelle, wo sich die beiden Leitungen für warme und kalte Luft vereinigen, ist ein Regelkörper 8 eingebaut. Dieser ist beispielsweise als Drehschieber ausgebildet, der die eine Leitung in dem Maße schließt, wie er die andere öffnet. Die durch den Kühler 15 einströmende Luft wird bei sinkender Kühlwassertemperatur mittels der Verschlußklappen 16 abgedrosselt oder ganz abgesperrt, die durch die Stange 17 und Hebel 18 von dem Thermostaten i9 aus verstellt werden. Der Thermostat i9 ist in den unteren Teil des Kühlers eingebaut und steht daher unter der Einwirkung der Kühlwassertemperatur. An den Hebel 18 ist weiter noch die Stange 2o angeschlossen, die den Regelkörper 8 für die kalte und warme Ansaugeluft verstellt. In der Abbildung ist die Stellung wiedergegeben, in der nach Erreichen der Höchsttemperatur in der Motorhaube der Thermostat die Verschlußklappen 16 ganz geöffnet und die Warmluftleitung 13 vollkommen geschlossen hat, so daß der Motor nur kalte Luft ansaugt.An example embodiment of the invention is shown in the drawing. The engine i is surrounded by the engine hood: 2. In order to be able to carry out the air temperature control effectively, the engine compartment is closed at the bottom, for example by the sheet metal plate 1z. The suction line is located on the carburetor side. The warm air is sucked in with the pipe 13 directly from the space inside the bonnet, the cold air with the pipe 1q. from the free atmosphere. A regulating body 8 is installed at the point where the two lines for warm and cold air unite. This is designed, for example, as a rotary valve that closes one line to the same extent as it opens the other. The air flowing in through the cooler 15 is throttled or completely shut off when the cooling water temperature drops by means of the closing flaps 16, which are adjusted by the rod 17 and lever 18 from the thermostat i9. The thermostat i9 is built into the lower part of the radiator and is therefore under the influence of the cooling water temperature. The rod 2o, which adjusts the control body 8 for the cold and warm intake air, is also connected to the lever 18. The figure shows the position in which, after reaching the maximum temperature in the bonnet, the thermostat has fully opened the flaps 16 and completely closed the warm air duct 13 so that the engine only draws in cold air.
