Abstract

The engine has an inlet slot in the cylinder sleeve and one outlet valve in cylinder head. The working cycle is completed over one crank revolution. In the working cycle the piston moves downwards under the pressure of expanding gases. The outlet valve opens and shortly after that the inlet slot in the cylinder wall is opened by the piston upper edge. Air is blown into the cylinder by a blower for exhausting combustion gases. The air is subsequently compressed when the piston moves upwards, fuel being then injected for ignition to continue the cycle.

Description

Friedrich Kohlhepp - «Ζ ~ Schlüchtern, den 11.1.77 Neuer DreitaktkolbenmotorFriedrich Kohlhepp - «Ζ ~ Schlüchtern, January 11th, 1997 New three-stroke piston engine

Die Erfindung betrifft einen Dreitaktkolbenmotor, der, bedingt durch einen Einlaßschlitz in der Mitte der Laufbuchse und einem Auslaßventil im Zylinderkopf seine Arbeit schon bei einer Kurbelumdrehung leistet.The invention relates to a three-stroke piston engine, due to an inlet slot in the middle of the liner and a Exhaust valve in the cylinder head already does its work with one turn of the crank.

Der Erfindung liegt die Aufgabe zugrunde ein möglichst kompaktes, leistungstarkes, leichtes und umweltfreundliches Antriebsaggregat zu schaffen, welches im Fahrzeug- und Maschinenbau eingesetzt werden kann.The invention is based on the object of a drive unit that is as compact, powerful, light and environmentally friendly as possible to create that can be used in vehicle and mechanical engineering.

Diese Aufgabe wird erfindungsmäßig dadurch gelöst, daß sich in der Mitte der Laufbuchse eines Kolbenmotors ein Einlaßschlitz befindet, durch den die Frischluft eingeblasen wird, die Abgase entweichen durch ein Ventil im Zylinderkopf.This object is achieved according to the invention in that there is an inlet slot in the middle of the cylinder liner of a piston engine through which the fresh air is blown in, the exhaust gases escape through a valve in the cylinder head.

Vorteile der Erfindung:Advantages of the invention:

1. Arbeit bei nur einer Umdrehung der Kurbelwelle.1. Work with just one revolution of the crankshaft.

2. Aufladung des Zylinders durch ein Gebläse.2. Charging of the cylinder by a blower.

3. Bessere Kraftstoffausnutzung durch höheren Wirkungsgrad.3. Better fuel economy through higher efficiency.

4. Bessere Verbrennung, da durch gute Füllung genügend Sauerstoff vorhanden ist und die Restgase vollständig ausgeblasen werden.4. Better combustion, as sufficient oxygen is available through a good filling and the residual gases are completely blown out will.

5. Die Schmierung erfolgt durch Öl in einer Ölwanne plus Ölpumpe, daher ist kein Kraftstoffgemisch erforderlich.5. The lubrication is carried out by oil in an oil pan plus an oil pump, so no fuel mixture is required.

6. Große Aus- und Einlaßöffnung.6. Large outlet and inlet port.

7. Nur ein Ventil im Zylinderkopf erforderlich.7. Only one valve required in the cylinder head.

8. Niedrige Abgastemperatur durch bessere Verbrennung und Frischluftunterstützung beim Ausblasen.8. Low exhaust gas temperature through better combustion and fresh air support when blowing out.

9. Je nach Auslegung kann das Prinzip mit Benzin oder Dieselkraftstoff betrieben werden.9. Depending on the design, the principle can be with gasoline or diesel fuel operate.

10. Es ist möglich, jede gewünschte Anzahl von Zylindern zu einem Motorblock zu vereinigen.10. It is possible to combine any desired number of cylinders into an engine block.

Beschreibung des Arbeitsablaufes in Anlehnung an die beigefügte Zeichnung.Description of the workflow based on the attached drawing.

Takt 1Measure 1

Der Kolben geht nach unten. Das Auslaßventil öffnet 75° vor UT und die Abgase entspannen sich. 66°vor UT wird durch die Kolbenoberkante der Einlaßschlitz in der Zylinderwand freigegeben.The piston goes down. The exhaust valve opens 75 ° before BDC and the exhaust gases relax. 66 ° before BDC is through the upper edge of the piston the inlet slot in the cylinder wall is released.

Der durch das Gebläse erzeugte Luftstrom tritt in den Zylinder ein, drückt die noch vorhandenen Abgase durch das Ventil ins Freie und füllt so den ganzen Zylinder mit Frischluft. Die Luftsäule von Ab- und Frischluft hat hierbei eine gemeinsame Richtung. Das Auslaßventil muß 47 nach UT geschlossen sein, sa das bis zur Schließung des Einlaßschlitzes durch den Kolben ( 66° nach UT ) noch zusätzlich eine Aufladung erfolgen kann.The air flow generated by the fan enters the cylinder, pushes the remaining exhaust gases through the valve into the cylinder Free and so fills the whole cylinder with fresh air. The air column of exhaust and fresh air has a common direction. The outlet valve must be closed 47 after BDC, see this until the piston closes the inlet slot (66 ° after UT) an additional charging can take place.

Takt 2Measure 2

Der Kolben geht weiter nach oben und komprimiert die eingeblasene Luft bis auf die üblichen Werte. Während dessen wird durch Benzineinspritzung ein gut zündbares Gemisch geschaffen, daß durch einen Zündfunken zur Verbrennung gelangt.The piston goes up further and compresses the air blown in to the usual values. Meanwhile, through Gasoline injection creates an easily ignitable mixture that is burned by an ignition spark.

Takt 3Measure 3

Duron den entstehenden Druck wird der Kolben nach unten gedrückt, er leistet Arbeit und der Vorgang kann sich ständig wiederholen·Duron the resulting pressure, the piston is pressed down, it does work and the process can be repeated over and over again

Die Steuerzeit beträgt für den Arbeitstakt 108°, für das Ausblasen der Abgase 122°, die Frischluftzufuhr 132° und das Komprimieren 114° bei einer Umdrehung.The control time for the work cycle is 108 ° for the blow-out the exhaust gases 122 °, the fresh air supply 132 ° and the compression 114 ° with one revolution.
