Abstract
Description
Die Erfindung bezieht sich auf einen Zweitaktmotor, der ohne Ölverlustschmierung arbeitet.The invention relates to a two-stroke engine, the works without oil loss lubrication.
Die bewegten Teile üblicher Zweitaktmotoren werden durch Öl, das entweder dem Treibstoff beigefügt wird oder durch eine Pumpe in den Einlaßkanal gespritzt wird, geschmiert. Die dadurch entstehenden Nachteile, wie z. B. hoher Schadstoffausstoß durch verbranntes Öl, sind hinreichend bekannt.The moving parts of conventional two-stroke engines are by Oil that is either added to the fuel or by a pump is injected into the inlet port, lubricated. The resulting disadvantages such. B. higher Pollutant emissions from burned oil are sufficient known.
Aufgabe der Erfindung ist es, einen Zweitaktmotor anzu geben, der ohne Ölverlustschmierung arbeitet und gleich zeitig durch einen besseren Füllungsgrad höhere Leistung erreicht. Diese Aufgabe wird dadurch gelöst, daß der Kolben (1) als Stufenkolben ausgebildet ist und sowohl am Kolbenkopf (1.1) als auch am Kolbenfuß (1.2) Dich tungsringe aufweist. Kolben, Kolbenbolzen und Zylinder wand können nun zwischen den Dichtringen von Kolbenkopf (1.1) und Kolbenfuß (1.2) geschmiert werden. Die Kur belwelle wird "viertaktüblich" durch Öl aus dem Ölsumpf geschmiert. Der Kurbelraum (9) ist hierbei durch den Zylinderboden vom Vorverdichterraum (8) getrennt. Die zylindrische Pleuelstange (2) führt durch den Abdicht schieber (12), dieser läßt Hub- und Pendelbewegung der Pleuelstange zu und dichtet dabei gasdicht ab. The object of the invention is to provide a two-stroke engine that works without oil loss lubrication and at the same time achieves higher performance through a better degree of filling. This object is achieved in that the piston ( 1 ) is designed as a stepped piston and has rings on both the piston head ( 1.1 ) and the piston foot ( 1.2 ). The piston, piston pin and cylinder wall can now be lubricated between the sealing rings of the piston head ( 1.1 ) and piston foot ( 1.2 ). The cure belwelle is "four stroke usual" lubricated by oil from the oil sump. The crank chamber ( 9 ) is separated from the pre-compressor chamber ( 8 ) by the cylinder bottom. The cylindrical connecting rod ( 2 ) passes through the sealing slide ( 12 ), this allows the connecting rod to move and oscillate and thereby seals gas-tight.
Wird der Durchmesser des Zylinderfußes (1.2) größer als der des übrigen Kolbens (1) ausgeführt, so ergeben sich folgende Vorteile:If the diameter of the cylinder base ( 1.2 ) is larger than that of the rest of the piston ( 1 ), the following advantages result:
Durch die größere Bohrung des Vorverdichterraumes (8) wird erheblich mehr Luft angesaugt und in den Hub- und Brennraum (17) gepreßt, dadurch entsteht ein aufgeladener Motor. Zudem entsteht zwischen Kolbenfuß (1.2) und Zylinderstufe (10) eine Pumpwirkung, die zur Schmierung des Kolbens verwendet werden kann. Die Betriebsweise wird in den Ausführungsbeispielen Fig. 1-3 näher er läutert.Due to the larger bore of the pre-compressor chamber ( 8 ), considerably more air is sucked in and pressed into the stroke and combustion chamber ( 17 ), which creates a supercharged engine. In addition, there is a pumping action between the piston foot ( 1.2 ) and the cylinder step ( 10 ), which can be used to lubricate the piston. The mode of operation is explained in more detail in the exemplary embodiments in FIGS. 1-3.
Fig. 1:
Bei der Aufwärtsbewegung des Kolbens wird unterhalb des
Kolbenfußes (1.2) Luft über den vom Abdichtschieber (12)
freigegebenen Einlaßkanal (6) angesaugt; gleichzeitig
das zur Schmierung des Kolbens vorher eingespritzte Öl
über den Ölablaufkanal (15) zurück in den Ölsumpf ge
fördert. Fig. 1:
When the piston moves upwards, air is sucked in below the piston foot ( 1.2 ) via the inlet channel ( 6 ) released by the sealing slide ( 12 ); At the same time, the oil previously injected to lubricate the piston is conveyed back into the oil sump via the oil drain channel ( 15 ).
Bei der Abwärtsbewegung des Kolbens wird die vorher an gesaugte Luft über den Überströmkanal (4), der nun vom Abdichtschieber (12) freigegeben wird, in den Hub- und Brennraum (17) gepreßt, dabei werden die Abgase über den Auslaßkanal (5) dem Katalysator zugeführt. During the downward movement of the piston, the air previously sucked in is pressed into the displacement and combustion chamber ( 17 ) via the overflow channel ( 4 ), which is now released by the sealing slide ( 12 ), the exhaust gases being discharged via the outlet channel ( 5 ) Catalyst fed.
Gleichzeitig wird unterhalb der Zylinderstufe (10) über Spritzdüsen (11) Öl gegen die Kolbenwand gespritzt. Dreht sich nun die Kurbelwelle (3) weiter, so wird der Kolben (1) wieder nach oben gedrückt, die Luft im Brenn raum (17) wird verdichtet, dabei wird durch die Einspritz düse (14) Kraftstoff eingespritzt. Im oberen Totpunkt wird das Gemisch durch die Zündkerze (13) gezündet und durch die sich ausdehnenden Gase der Kolben wieder nach unten gedrückt.At the same time, oil is sprayed against the piston wall below the cylinder stage ( 10 ) via spray nozzles ( 11 ). Now the crankshaft ( 3 ) rotates further, the piston ( 1 ) is pushed up again, the air in the combustion chamber ( 17 ) is compressed, fuel is injected through the injection nozzle ( 14 ). At top dead center, the mixture is ignited by the spark plug ( 13 ) and the pistons are pushed down again by the expanding gases.
Ebenso könnte dieser Motor als Selbstzünder arbeiten. Hierbei wird die Luft im Brennraum höher verdichtet. Im oberen Totpunkt wird Treibstoff eingespritzt, der sich selbst entzündet.This engine could also work as a self-igniter. The air in the combustion chamber is compressed to a higher degree. in the Top dead center is injected with fuel that is self-ignited.
Fig. 2:
Die Betriebsweise ist die gleiche wie unter Fig. 1 be
schrieben. Die Hubbewegung des Kolbens wird über die
Kolbenstange (21) und die Pleuelstange (2) auf die
Kurbelwelle (3) übertragen. Kurbel und Vorverdichter
raum sind ebenfalls durch den Zylinderboden getrennt,
der eine Öffnung für die Kolbenstange (21) aufweist.
Ein- und Auslaßöffnung des Vorverdichterraumes werden
durch Ventile geöffnet bzw. geschlossen. Kolbenfuß und
Kolbenkopf haben denselben Durchmesser.
Fig. 2:
The mode of operation is the same as that described under FIG. 1. The stroke movement of the piston is transmitted to the crankshaft ( 3 ) via the piston rod ( 21 ) and the connecting rod ( 2 ). Crank and pre-compressor space are also separated by the cylinder bottom, which has an opening for the piston rod ( 21 ). The inlet and outlet openings of the pre-compressor chamber are opened and closed by valves. Piston base and piston head have the same diameter.
Die Schmierung erfolgt über Kanäle (20) und Ausfräsungen (19) am Kolbenmantel.Lubrication takes place via channels ( 20 ) and cutouts ( 19 ) on the piston skirt.
In Fig. 3:
sind Vorverdichter und Kurbelraum nicht ge
trennt. Bei Aufwärtsbewegung des Kolbens wird Luft über
das Kurbelgehäuse angesaugt, die bei Abwärtsbewegung im
unteren Totpunkt durch ein Ventil (23) im Kolben in den
Brennraum gelangt. Die Schmierung erfolgt über Pleuel
bolzen, Pleuelstange und Kurbelwelle, die hohl ausge
bildet sein müssen. Der Durchmesser des Kolbenfußes ist
geringfügig größer als der des übrigen Kolbens. Bei
Aufwärtsbewegung des Kolbens wird der Raum zwischen
Kolbenfuß und Zylinderstufe mit Öl vollgesogen, das
bei Aufwärtsbewegung über Pleuelbolzen, hohle Pleuel
stange (2.1) und hohle Kurbelwelle (3.1) wieder in den
Ölkühler (16) gepreßt wird.In Fig. 3:
the pre-compressor and the crankcase are not separated. When the piston moves upwards, air is sucked in via the crankcase and, when it moves downwards at bottom dead center, reaches the combustion chamber through a valve ( 23 ) in the piston. Lubrication is carried out using a connecting rod bolt, connecting rod and crankshaft, which must be hollow. The diameter of the piston foot is slightly larger than that of the rest of the piston. When the piston moves upwards, the space between the piston foot and the cylinder stage is soaked with oil, which is pressed back into the oil cooler ( 16 ) when the piston rod, hollow connecting rod ( 2.1 ) and hollow crankshaft ( 3.1 ) move upwards.
Selbstverständlich können Kombinationen aus allen dar gestellten Figuren zur Anwendung kommen.Of course, combinations of all can be posed figures are used.
