Abstract
Description
Verbrennungsmotor Internal combustion engine
Der Verbrennungsmotor ist ein Viertakthubkolbenmotor ohne Kurbelwelle, der bei einer Umdrehung der Hauptwelle alle 4 Takte abschließt.The internal combustion engine is a four-stroke piston engine without a crankshaft, which completes every 4 cycles with one rotation of the main shaft.
Der Motor ist aufgebaut aus einem Gehäuse (11), Zylinder (3), Kolben (5), Zylinderansatz (7), Kolbenführung bei Zeichnung I (9), bei Zeichnung II Kranz (8), Hauptwelle (10), die mit der Kolbenführung (9) fest verbunden ist und Zylinderkopt (3) mit Ein- und Auslaßventilen <1).The engine is made up of a housing (11), cylinder (3) and pistons (5), cylinder attachment (7), piston guide in drawing I (9), in drawing II wreath (8), main shaft (10), which is firmly connected to the piston guide (9) and cylinder head (3) with inlet and outlet valves <1).
Der Kolben (S) ist mit der Kolbenführung (9) durch eine große Rolle (6) und zwei kleinen Rollen (8) verbunden. Die große Rolle rollt sich an der äußeren Bahn der Kolbenführung ab. Die kleinen Rollen rollen sich an den inneren beiden Bahnen ab.The piston (S) is connected to the piston guide (9) by a large roller (6) and two small rollers (8) connected. The big role rolls on the outer one Path of the piston guide. The small rolls roll on the inner two Orbits.
Der Kolben ist am oberen Teil zylindrisch mit Dichtungs- und Ölabstreifringen versehen und bewegt sich im Zylinder.The upper part of the piston is cylindrical with sealing and oil control rings provided and moves in the cylinder.
Der untere Teil mit seinen Gleitflächen bewegt sich im Zylinderansatz und nimmt den zeitlichen Druck auf. Die Ventile werden durche di Nocken auf der Hauptwelle angetrieben.The lower part with its sliding surfaces moves in the cylinder base and takes on the time pressure. The valves are driven by the cams on the Main shaft driven.
Bei Zeichnung I bewegt: sich die Kolbenführung gegen den Uhrzeiger und der Kolben steht m tiefsten Totpunkt. Bei weiterer Umdrehung um 900 öffnet sich das Auslaßventil und der Kolben schiebt die Gase restlos aus. Am oberen Totpunkt öffnet sich das Einlaßventil und reines Kraftstoff luftgemisch wird angesaugt bei der weiteren IJmtlrehuncr um 900.In drawing I: the piston guide moves counterclockwise and the piston is at the lowest dead point. With a further rotation of 900 it opens the outlet valve and the piston push the gases out completely. At top dead center the inlet valve opens and pure fuel air mixture is sucked in at the further IJmtl revolutions around 900.
Der Ansaughub ist kleiner als der Ausdehnungshuh. Die beiden Hube kennen heliebig gewählt werden.The suction stroke is smaller than the expansion stroke. The two hatches can be chosen at will.
Bei der weiteren Umdrehung m 900 werden die Gase verdichtet nach dem gewiinschten Verdichtungsgrad. Jetzt erfolgt die Zündung und die Gase dehnen sich aus. Die Kraft überträgt sich durch den Kolben, große Rolle, Kolbenführung auf die Achse in kreisender Bewogung .With the further rotation m 900, the gases are compressed according to the Desired degree of compaction. Ignition now takes place and the gases expand the end. The force is transmitted through the piston, large roller, piston guide to the Axis in circling motion.
m unteren Totpunkt überschreitet der Kolben die Auslaßöffnungen und ein Teil der Gase entweicht. Der Druck im Zylinder fälfast BTS Zum atmosphärischen Druck.At the bottom dead center, the piston passes the outlet openings and some of the gases escape. The pressure in the cylinder almost falls BTS to atmospheric Pressure.
Diese Funktion ist möglich durch den Aufbau der Kolbenführung, der 4 verschiedene Achsabstände hat.This function is possible due to the structure of the piston guide, the Has 4 different center distances.
Vorteile gegenüber dem Otto-Motor: 1. Der Gang des Kolbens ist bei dem Otto-Motor bei allen 4 Takten gleich und dadurch bleiben Restgase im Zylinder. Bei unserem Motor werden die nhas restlos ausgestoßen und es wird reines Kraftstoffluftgemisch angesaugt. Dadurch erreicht man eine bessere Verbrennung und eine höhere Temperatur.Advantages over the Otto engine: 1. The gear of the piston is at the same as for the Otto engine in all 4 strokes, which means that residual gases remain in the cylinder. In our engine, the nhas are completely ejected and it becomes a pure fuel-air mixture sucked in. This results in better combustion and a higher temperature.
2. Das Aursdehntlngsrrolumen ist größer als das Ansaugvolumen, dadurch kann man besser die restliche Energie der Abgase ausnützen und der Wirkunqsqrad ist erhöht.2. The Aursdehntlngsrrolumen is larger than the suction volume, thereby one can better utilize the remaining energy of the exhaust gases and the efficiency is increased.
3. Weil die Abgase am untersten Teil des Zylinders entweichen können, fällt die Temperatur im Zylinder und der Motor braucht weniger gekühlt werden.3. Because the exhaust gases can escape at the lowest part of the cylinder, the temperature in the cylinder falls and the engine needs less cooling.
4. Bei dem Otto-Motor hat ein jeder Kolben eine Pleulstange und eine Kurbelwelle. Bei unserem Motor kann man an einer Kolbenführung oder an einem Kranz mehrere Kolben anschließen, dadurch wird ein zuräzlicher Wirkungsgrad erreicht.4. In the Otto engine, each piston has a connecting rod and one Crankshaft. With our engine you can use a piston guide or a ring connect several pistons to achieve additional efficiency.
5. Bei dem Otto-Motor sind die hin- und hergehenden Massen sehr groß. Bei unserem Motor sind die hin- und hergehenden Massen sehr gering. Sie entsprechen nur dem Gewicht des Kolbens.5. In the Otto engine, the reciprocating masses are very large. With our engine, the reciprocating masses are very small. You correspond just the weight of the piston.
6. Bei dem Otto-Motor braucht man für den Ventil antrieb eine zusätzliche Anlage. Bei unserem Motor werden die Ventile nur durch 2 Nocken an der Hauptwelle angetrieben.6. With the Otto engine you need an additional one for the valve drive System. In our engine, the valves are only activated by 2 cams on the main shaft driven.
7. Bei unserem Motor gibt es keine Schwierigkeiten bei der Schmierung, da alle Teile, die geschmiert werden, sich innerhalb der Gehäuse befinden. Die Teile schmieren sich durch Zerstäubung des Öls, das sich durch Eintauchen der Kolbenführung in das Öl bildet.7. Our engine has no lubrication problems, because all parts that are lubricated are inside the housings. The parts lubricate themselves by atomizing the oil, which is obtained by immersing the piston guide forms in the oil.
8. Der Aufbau unseres Motors gebenüber dem Otto-Motor ist einfacher, leichter und billiger, das Gewicht ist geringer und der Umfang des Motors ist raumsparender. Die Zündung ist auch einfacher.8. The structure of our engine is easier than the Otto engine, lighter and cheaper, the weight is lower and the size of the engine is more space-saving. Ignition is also easier.
