Abstract
Description
Die
Erfindung betrifft eine spezielle Ausbildung von Brennkraftmaschinen,
wie sie für den schadstoffarmen Gegenkolbenmotor nach Patent
Sie legt die besonderen technischen Mittel dar, wie sie für einen schmierölfreien Betrieb in der Kolben/Zylinder-Gruppe bezüglich der Kolben- und Zylindergestaltung, der Werkstoffe, der Paarungs- und Schmierverhältnisse, der Schmiermittel sowie der Triebwerksgestaltung erforderlich sind.she lays down the special technical means, as they are for a lubricating oil-free operation in the piston / cylinder group with regard to the piston and cylinder design, the materials, the mating and lubricating conditions, the lubricant and the engine design are required.
Es sind bereits eine Reihe von Erfindungsvorschlägen bekannt, welche durch Einsatz von Werkstoffen wie Kohlenstoff/Feinkorngrafit, Keramik und anderen Sonderwerkstoffen einen schmierungsarmen Betrieb ermöglichen.It There are already a number of proposals for invention known which by using materials such as carbon / fine grain graphite, Ceramics and other special materials a low-lubrication operation enable.
So
beschreiben die
Eine Schmierungsfreiheit wird dabei nicht erreicht, weil durch die zum Triebwerksraum offene Zylinderbüchse (Tauchkolbenbauart) ein Einschleudern von Abspritzöl vom Triebwerk in diese Zylinderbüchse nicht verhindert werden kann.A Lubrication is not achieved because of the for Engine room open cylinder liner (plunger type) a slinging of injection oil from the engine in this Cylinder liner can not be prevented.
So
werden bei diesen Erfindungen, wie z. B. in der o. g.
Die Vorzüge beispielsweise eines Kohlenstoffkolbens bestehen bei diesen Erfindungsvorschlägen im geringerem Gewicht, kleinerem Einbauspiel, bes. im Feuerstegbereich, und in der hohen Warmfestigkeit des Kohlenstoffs. Ein ölfreier Betrieb in der Kolben/Zylinder-Gruppe kann, wie erwähnt, wegen der Tauchkolbenbauart nicht erreicht werden.The Advantages of, for example, a carbon piston exist in these proposals for invention in the lighter weight, smaller installation play, in particular in the Feuerstegbereich, and in the high heat resistance of carbon. Oil-free operation in the piston / cylinder group can, as mentioned, not reached because of the plunger type become.
Es verbleibt stets ein Ölfilm auf der Zylinderinnenwand und dieser, nur wenige μm dicken Schicht kommt für die Emissionen eine hauptsächliche, stark umweltbelastende Rolle zu.It always remains an oil film on the cylinder inner wall and this, only a few microns thick layer comes for the emissions are a major, heavily polluting Role too.
Der Ölfilm verdampft und brennt, während der Kolben im Arbeitstakt die Zylinderwanderung freigibt, mit ab und ist für einen hohen Schadstoffausstoß verantwortlich. Die Kohlenwasserstoffe (Soluble Organic Fraktion-SOF), die Nitrate, Phosphate, Salze, Aschen (Non Soluble Fraktion-NSF) werden in erheblichem Maße vom mit verbrennenden Ölfilm verursacht. Sie werden umso höher, je größer der Ölverbrauch eines Motors im Laufe seiner Betriebszeit ist.The oil film evaporates and burns while the piston is working The cylinder migration releases with and is for one responsible for high pollutant emissions. The hydrocarbons (Soluble Organic Fraction-SOF), the nitrates, phosphates, salts, ashes (Non Soluble Fraction-NSF) are used extensively by caused by burning oil film. They get higher, the greater the oil consumption of an engine in the course of its operating time.
Dabei wird er Ölverbrauch zu etwa 75% von der Kolben/Zylinder-Gruppe bestimmt, ihr kommt also eine Schlüsselrolle bei der Entstehung der Schadstoffemissionen zu [4; 5; 6].there It will consume about 75% of the piston / cylinder group's oil consumption Certainly, so you have a key role in the creation pollutant emissions to [4; 5; 6].
Ein weiterer, von der Tauchkolbenbauart mit offenem Zylinderrohr bedingter Nachteil ist die Verschmutzung und Versäuerung des Motoröles infolge der blow-by-Gase. Insbesondere bei Biogas- und Biodieselmotoren sind deshalb Ölwechsel nach erheblich kürzeren Betriebszeiten erforderlich. Dies führt bei Anlagen mit erneuerbaren Energien, z. B. Blockheizkraftwerken, zu deutlich erhöhten Kosten. Zudem ist der stärkere, nach Tausenden Liter zu messende Anfall von Altöl kein Beitrag zur Umweltentlastung.One Other, of the plunger type with an open cylinder tube conditional Disadvantage is the pollution and acidification of the engine oil as a result of the blow-by gases. Especially for biogas and biodiesel engines are therefore oil changes after considerably shorter ones Operating times required. This leads to installations renewable energies, eg As combined heat and power plants, increased significantly Costs. In addition, the stronger, after thousands of liters too measuring accumulation of waste oil no contribution to environmental relief.
Der Erfindung liegt die Aufgabe zugrunde, in luft- oder gemischverdichtenden Kolbenmaschinen, die nach dem Zweitakt- oder Viertaktverfahren oder als Kompressoren arbeiten, einen absolut schmierungsfreien – oder zumindest steuerbaren Mangelschmier-Betrieb in der Kolben/Zylinder-Gruppe zu ereichen und das Eindringen von Verbrennungsgasen in den Triebwerksraum zu unterbinden.Of the Invention is based on the object in air or mixture compressing Piston engines, after the two-stroke or four-stroke process or as Compressors work, an absolutely lubrication - or at least controllable lean lubrication operation in the piston / cylinder group to reach and the penetration of combustion gases into the engine room to prevent.
Diese
Aufgabe wird erfindungsgemäß dadurch gelöst,
dass auf der Basis der Patente
Die Basis ist die in [1] und [7] gezeigte, besondere Kreuzkopfbauart, welche eine völlig öldichte Abschirmung der Kolben/Zylinder-Gruppe vom Triebwerksraum gewährleistet und alle Seitenkräfte (Normalkräfte) auf den bei ölfreiem Betrieb besonders verschleißempfindlichen Kolben vermeidet.The The basis is the special crosshead type shown in [1] and [7], which is a completely oil-tight shielding of the piston / cylinder group guaranteed by the engine room and all lateral forces (Normal forces) to the oil-free operation particularly sensitive to wear Avoids piston.
