Abstract

In internal combustion engines with mixture formation in the cylinder the time available for mixture formation and ignition is very short. The consumption, emission and noise levels are essentially a function of the mixture formation and ignition delay. Immediate heating of the fuel after entering the combustion chamber speeds up the mixture formation and reduces the ignition delay. Internal combustion engines on this principle can be operated with different fuels with favourable consumption, emission and noise levels. <IMAGE>

?eSchreibung? eScription

GlühzündVorrichtung für eine Brennkraftmaschine nach Oberbegriff des Anspruchs 1 .Glow ignition device for an internal combustion engine according to the preamble of claim 1.

Bei Brennkraftmaschinen mit Genischbildung im Zylinder arbeitet man im allgemeinen mit Verdichtungsverhältnissen , die über den zum optimalen Betrieb bezüglich spezifischem Verbrauch , G-eräuscharmut und Schadstoffgehalt nötigen Werten liegen , um ein sicheres Starten auch bei niedrigen Temperaturen sicherzustellen .In internal combustion engines with genetics in the cylinder one works in general with compression ratios that are specific to the optimum operation with respect to Consumption, low G noise and pollutant content Values are also low to ensure a safe start Ensure temperatures.

Durch Glühzündvorrichtungen wird ein sicheres Starten auch bei niedrigen Verdichtungsverhältnissen und vor allem bei unterschiedlichen Kraftstoffen ermöglicht . Üblich ist es , die Glühsündvorrichtungen entweder im Brennraum selbst oder in Vor- bzw. Zündkammern unterzubringen . In jedem Falle werden die natürlichen Strömungsverhältnisse gestört oder wie bei einer Vorrichtung (deutsche Patentschrift Nr. 32 24 048) der Brennraum zerklüftet , wodurch sich sowohl thermische als auch Strömungsverluste ergeben .Da Brennstoff durch die Strömung in die Zündkammer gerissen werden muß , sich dort entzündet und dann erst durch den Druckanstieg als Flamme in den Hauptbrennraum zurückschlägt und dort die Verbrennung des inzwischen eingetretenen Brennstoffs einleitet , ist mit einer starken Zündverzögerung und damit geräuschvollem Lauf zu rechnen .A reliable starting is ensured by pre-ignition devices even at low compression ratios and above all with different fuels. It is common to place the glow ignition devices either in the combustion chamber itself or to be accommodated in pre- or ignition chambers. In any case, the natural flow conditions are disturbed or as in a device (German Patent No. 32 24 048) the combustion chamber is fissured, which means that both thermal as well as flow losses result. Because fuel has to be torn by the flow into the ignition chamber, ignites there and only then by the rise in pressure flashes back into the main combustion chamber as a flame and initiates the combustion of the fuel that has now entered , a long ignition delay and thus noisy running is to be expected.

25'Der Erfindung liegt die Aufgabe zugrunde , eine Brennkraftmaschine zu schaffen , die weitgehend unabhängig vom verwendeten Brennstoff mit niedrigem spezifischem Verbrauch , bei geringer Geräusch- und Schadstoffentwicklung , läuft .The invention is based on the object of an internal combustion engine to create that are largely independent of the fuel used with low specific consumption, with low noise and pollutant development, runs.

Dazu ist es nötig , eine vollkommene und gleichmässige Verbrennung zu erzielen , also den "Brennstoff möglichst sofort nach seinem Eintritt in den Brennraum zu entzünden und mit einen möglichst grossen Teil der angesaugten Luft in Berührung zu bringen . Dabei soll der Verbrennung möglichst v/enig Energie z.B. durch Wärme- oder Strömungsverluste entzogen werden . For this it is necessary to have a perfect and even To achieve combustion, so the "fuel" if possible to ignite immediately after entering the combustion chamber and with as large a portion of the sucked in air as possible to bring in touch. As little energy as possible should be extracted from the combustion, e.g. through heat or flow losses.

SrfindungsgemKß ist die Aufgabe dadurch gelöst , daß der Glühkörper direkt in den Brennstoffstrahl gelegt wird , zwar derart , daß die durch Quetschwirkung zwischen Kolben und Zylinder hervorgerufenen Luftströmungen an ihn vorbeistreichen und den aufbereiteten und entzündeten Brennstoff abtragen . Die sich in oberen Totpunkt ergebende * Brennraumform, stellt der toroidförmigen Strömung den ge- } According to the invention, the object is achieved in that the incandescent body is placed directly in the fuel jet in such a way that the air currents caused by the squeezing action between piston and cylinder sweep past it and remove the processed and ignited fuel. The resulting in TDC * combustion chamber shape, the toroidal flow the overall}

Je nach zu erwartendem Verwendungszweck der Brennkraftmaschine kann der Glühkörper und seine Befestigung entweder so ausgelegt sein , daß bei Vollast die ontinale Betriebstemperatur erreicht wird und im Teillastbereich der Glühkörper elektrisch beheizt wird oder daR die optimale Betriebstemperatur selbsttätig bereits im Teillastbereich erreicht wird und bei höherer Belastung der Glühkörper , vor allem zur Verminderung des Stickozidausstos-Weight, is thrown outwards and comes into contact with the remaining fuel. Depending on the expected use of the internal combustion engine, the incandescent body and its fastening can either be designed in such a way that the ontinal operating temperature is reached at full load and the incandescent body is electrically heated in the partial load range or that the optimum operating temperature is reached automatically in the partial load range and with higher loads Incandescent bodies, especially to reduce nitrogen oxide emissions

Siliziunnitrid-Sinterkeramik , herzustellen .larger load range neither heated nor cooled, it is made of an extremely heat-resistant material in order to withstand the stresses that occur at full load, z.3. Silicon nitride sintered ceramics.

Durch Verwendung eines katalytisch die Zündung einleitenden Stoffes kann der Arbeitstemperaturbereich des Glühkörpers nach tieferen Temperaturen ausgeweitet v/erden , durch eine entsprechend stärkere thermische Ankoppelung an den gekühlten Zylinderkopf kann so eine Überhitzung auch über einen grösseren Lastbereich vermieden werden .By using a substance which catalytically initiates ignition, the working temperature range of the incandescent body expanded after lower temperatures, through a correspondingly stronger thermal coupling to the cooled In this way, cylinder head overheating can also be avoided over a larger load range.

Auch durch die Verwendung einer EinsOritzvorrichtung , die wahlweise mehr den Glühkörper mit Brennstoff beaufschlagt oder in die umliegenden Zonen spritzt , kann die ' Temperatur des Glühkörpers beeinflusst werden . Die Steuennr dieser Vorrichtung kann entweder von Aussen , z.B. elektronisch oder in Abhängigkeit von der eingespritzten Brennstoffmenge erfolgen .Also through the use of an inserting device, which either applies more fuel to the incandescent body or injects it into the surrounding zones, the ' Temperature of the incandescent body can be influenced. The tax number this device can either be externally, e.g. electronically, or depending on the injected Amount of fuel.
