Description

Die folgende Erfindung betrifft eine Vorrichtung zur Zündung beim Start und Betrieb von Dieselmotoren.The following invention relates to a device for ignition when starting and operating Diesel engines.

Die Zündung des Kraftstoffes beim Start und Warmlauf von Dieselmotoren erfolgt durch Starthilfen in Form von Glühkerzen oder Ansaugluftvorwärmung. Die Glühkerze ragt mit ihrem Heizelement in den Brennraum und ist aus Sicht der Konstruktion äußerst störend in der räumlich durch Einlass- und Auslassventile, Einspritzdüse und Kühlkanäle beengten Situation. Glühkerzen und Ansaugluftvorwärmung haben einen hohen Verbrauch an elekt­ rischer Energie, der besonders im Fall des Kaltstarts bei niedrigen Temperaturen zu ver­ meiden ist.The ignition of the fuel when starting and warming up diesel engines is carried out by Starting aids in the form of glow plugs or intake air preheating. The glow plug protrudes their heating element in the combustion chamber and is extremely disruptive in terms of construction which is spatially restricted by intake and exhaust valves, injection nozzle and cooling channels Situation. Glow plugs and intake air preheating have a high consumption of elect energy, which is particularly important in the case of cold starts at low temperatures is to be avoided.

Aufgabe der vorliegenden Erfindung ist es ohne Verbrauch elektrischer Energie und ohne behindernde Bauteile einen schadstoff- und geräuscharmen Start und Warmlauf mit hoher Laufruhe zu ermöglichen.The object of the present invention is without consumption of electrical energy and without obstructing components a low-pollutant and low-noise start and warm-up with high To enable smooth running.

Diese Aufgabe wird gemäss der Erfindung durch einen Katalysator gelöst, der thermisch isoliert, vorzugsweise durch Keramik, auf ein den Brennraum begrenzendes Bauteil aufge­ bracht durch Kontaktkatalyse mit dem Gemisch aus eingespritztem Kraftstoff und ver­ dichtetem Gas eine Verbrennung einleitet.This object is achieved according to the invention by a catalyst which is thermal insulated, preferably by ceramic, applied to a component delimiting the combustion chamber brings through contact catalysis with the mixture of injected fuel and ver sealed gas initiates combustion.

Der Katalysator, vorzugsweise ein Übergangsmetall wie zum Beispiel Platin oder ein Me­ talloxid mit Halbleitereigenschaft, erhöht die Reaktionsgeschwindigkeit der Oxidation (Verbrennung) und reduziert so die den Verbrennungsvorgang bestimmende Zündverzugs­ zeit. Das Material, die Größe der Oberfläche und die Temperatur des Katalysators beein­ flussen die Wirksamkeit.The catalyst, preferably a transition metal such as platinum or a Me Tall oxide with semiconductor properties, increases the reaction rate of the oxidation (Combustion) and thus reduces the ignition delay that determines the combustion process time. The material, the size of the surface and the temperature of the catalyst affect flow the effectiveness.

Die katalytische Oxidation von Kohlenwasserstoffen aus Kraftstoffrückständen einer un­ vollständigen motorischen Verbrennung wird in Abgaskatalysatoren bei Kraftfahrzeugen bereits eingesetzt. Die Umsetzungsrate beträgt bei einer Katalysatortemperatur größer 250°C mehr als 90%.The catalytic oxidation of hydrocarbons from fuel residues of an un Complete engine combustion is used in catalytic converters in motor vehicles already used. The conversion rate is greater at a catalyst temperature 250 ° C more than 90%.

Die thermische Isolation des Katalysators gegenüber dem Trägerbauteil verhindert einen Wärmeabfluss. Die minimale Wärmekapazität der vergleichbar mit Abgaskatalysatoren dünnen Katalysatorschicht führt zu einem der Kompressionstemperatur im Arbeitstakt fol­ genden Temperaturverhalten. Die Kompressionsendtemperatur des Gases im Arbeitstakt ist selbst unter Kaltstartbedingungen, Temperaturen kleiner -25°C und niedriger Starter­ drehzahl, größer 250°C und damit deutlich höher als die Temperaturen der den Brennraum begrenzenden Bauteile. Im Warmlauf und den übrigen Betriebszuständen unterstützt die Katalysatorschicht durch ihre hohe Temperatur die Entflammung. Dieser für den Diesel­ motor positive Effekt ist vergleichbar dem beim Ottomotor unerwünschten Effekt der Vor­ entflammung.The thermal insulation of the catalyst from the carrier component prevents one Heat flow. The minimum heat capacity comparable to that of catalytic converters  thin catalyst layer leads to a compression temperature in the work cycle fol temperature behavior. The final compression temperature of the gas in the work cycle is even under cold start conditions, temperatures below -25 ° C and low starter speed, greater than 250 ° C and thus significantly higher than the temperatures of the combustion chamber limiting components. The supports in warm-up and the other operating states Due to its high temperature, the catalyst layer ignites. This one for the diesel engine positive effect is comparable to the undesirable effect of the gasoline engine inflammation.
