ich glaube nicht, dass pro Zylinder wirklich drei Ventile vorhanden waren. Das linke Ventil ist Einlassventil (Frischluft), das rechte Auslassventil und in der Mitte ist irgendein Steuerventil (Kraftstoffzufuhr) oder von der Lage am Kopf ausgehend irgendeine Wippmechanik, die was mit der Zündung zutun haben könnte. Der Kipphelbel hat auch einen wesentlich dünneren Stößel. Jedenfalls glaube ich fest, dass die Sequenz der beiden außen liegenden Stößel aussieht wie in diesen youtube-clips: http://www.youtube.com/watch?v=UuDYl...eature=related http://www.youtube.com/watch?v=_SK7f...eature=related http://www.youtube.com/watch?v=37qYW...eature=related http://www.youtube.com/watch?v=gd9qwUE8dXU WWI U-Bootdiesel: http://www.youtube.com/watch?v=03adw...eature=related http://www.youtube.com/watch?v=9o_4n...eature=related http://www.youtube.com/watch?v=Hm4YO...eature=related ------------------------------------------------------------------------- Hi Tomi, I don't think that there were three valves for each cylinder. The left valve is entrance (air), the right valve is for exhaust and in the middle is something like a control valve (diesel injection) or, based on the location at the cylinder head, a mechanic for (spark) ignition. For that I truly believe the sequence of the outer valves is the same as in the youtube clips... |
I found an original clip of a uboat diesel:
http://www.youtube.com/watch?v=2vQ8uWHo4uw At 0:48 to 0:52 you can see that the middle valve isn't working. |
Diesel Rytmus TYP II
@Kaleun_Endrass :up:
Für dem MWM RS127 S 350PS 1000U/min Ist glaube ich der richtige Rytmus ..:up: http://www.youtube.com/watch?v=UuDYl...eature=related . 1 2 3 ,1 2 3 ,1 2 3 ,1 2 3 ,1 2 3 ,1 2 3 ,1 2 3 ,1 2 3 ,1 2 3 ,1 2 3 ,1 2 3 ,1 2 3 ,1 2 3 ,1 2 3 , . was glaubt ihr ??:hmmm: |

Hey Tomi,
the animation looks good so far, but if you keep that cycle in real it would propably kill the cylinder head. Now I have a technical reference myself to give a helping hand... here is a diagram for your four strokes: The three pusher (Stößel) are for 1) Einlassventil (Intake valve) 2) Rollenabhebenocken (Interrupter or Timimg Cam) 3) Auslassventil (Exhaust valve) ............ 1.T. 2.T. 3.T. 4.T. 1 Valve (L): ---ö|os--|----|---- 2 Valve (M): ----|----|----|---- 3 Valve (R): ----|----|----|öoob ............ u o |u o |u o |u o piston.....: _/-\ _/-\ _/-\ _/-\ The legend for the valves: ö = is opening o = is full open s = is closing b = right at the beginning of the movement to lower cylinder position the valve is almost closed As you can see, the middle "valve" wasn't used for a combustion of the cylinder. It was a mechanic to be able to let the engine rotate reverse. The lower crankshaft was rotated several degrees to change the engines timing when operating reverse. See: http://www.uboatarchive.net/U-570Plate30A.htm |
Simulation
Moin !!
Kaleun_Endrass Ich habe die Schematick oben in Excel dargestellt. Ist es möglich dass du mir das so darstellst wie oben. Damit kann ich die Position der Stößel gut erkennen. Was für die Simulation wichtig ist . Denkst du das der Motor gewisser Vibration bei Vollgas Ausgesetzt war. Und der Winkel der Stößel dach oben und unten, ist der o.k.?? Gruß Tomi. Alle Veränderungen werden von Diving Duck übernommen, und überarbeitet. Ich hoffe er gibt hier ein Feedback ab!! Das würde mich freuen. Gruß Tomi Moin! Kaleun_Endrass I have the schematick shown above in Excel. Is it possible that you show me the way as above. So I can see well the position of the plunger. What is important for the simulation. Do you think that some of the engine vibration at full throttle Was suspended. And the angle of the plunger up and down the roof, which is ok? Greeting Tomi. All changes will be accepted by Diving Duck and revised. I hope he makes a feedback here! That would be nice. Greeting Tomi |
Hi Tomi,
habe ein Update zum Motor und zu den Steuerzeiten. Der mittlere Stößel treibt das Anlassventil, durch das der Motor mittels Druckluft gestartet werden kann. Sobald der Motor zündet, werden die Anlassventile nicht mehr von der Nockenwelle mitbewegt und der mittlere Stößel u. Kipphebel bleiben stehen. Habe eine Excel-Tabelle hochgeladen, in der die Steuerzeiten für alle 6 Zylinder der Backbord und der Steuerbord-Maschine stehen. Die Zahlenwerte in den Zellen sind in mm und bezeichnen den Hub der Stößelstangen. Link: http://rapidshare.com/files/30591872...eiten.xls.html ------------------------------------------------------------------------- I have an update for the engine and its timing. The middle push rod moves the starting valve, which is used to start the engine with pressurized air. As soon as the engine is firing itself the starting valve isn't moved by the camshaft any longer and the middle push rod and rocker stand still. The uploaded excel file contains the timing for all six cylinders of the port and starboard engine. The values of the cells are in millimeters and symbols the stoke of the push rods. |

MOIN !! Kaleun_Endrass Great job, where you get those figures yet. It is hard to imagine how to function as the pistons. I fear that it is a problem for me!:oops: Sorry!:dead: |
Moin,

At the moment I´ve got a set of moving parts imported into a separate *.dat file. Nothing more until now. I´m going to do some tests on linking it to different speeds. That´s the actual state of progress from my side. Moin Tomi, mach mich nicht verrückt. Ich weiß ja, daß Du detailverliebt bist, aber lass mich erst mal die Geschwindigkeiten der Animation und des U-Boots miteinander verlinken. Danach können wir über den Rythmus sprechen, den wahrscheinlich sowieso nie jemand bemängeln würde. Hauptsache da zappelt was. LOL. Wegen Dir bekomme ich noch ´ne Glatze. ;) Bisher habe ich lediglich ein kleines Set sich bewegender Teile in eine separate *.dat importiert. Ich fange jetzt damit an, diese testweise mit verschiedenen Geschwindigkeiten des Boots zu verlinken. Das ist der aktuelle Stand. Regards, DD |
Moin,
as said above, the sequence does not bother me at the present stage of development. Most important for me was to link different speeds of animation to different speed settings. http://i182.photobucket.com/albums/x...engine_002.jpg Meanwhile I´ve been able to link engine animation speed to engine order telegraph settings. This is a short preview. It is still buggy, but it works. The animation does not show correctly in this video, because of the frame rate. The scene has been captured at 60FPS (FRAPS does not support higher FPS) and been converted to 30FPS to match YouTube requirements. You should see the valves blurred at high speeds. ;) Regards, DD |
:salute: Very well done :yeah:, Congratulations :DL

It looks absolutely great...any ETA for a possible download? Will it be available before SH5? :yep:
I do a bit of modding, modeling in 3ds etc, so I'm curious to take a closer look... :) |
Steuerzeiten, Simulation
Hey Tomi & DivingDuck,
I uploaded the sequence of an abstract MWM RS127S engine in 3dsmax format and an example video on youtube. MAX file: http://rapidshare.de/files/48772127/...s_sim.max.html Youtube: http://www.youtube.com/watch?v=8yZZmN2L618 |
Great work guys....your certainly setting the bar high http://www.psionguild.org/forums/ima...ies/pirate.gif

:up: Hmm looks really good, only on the YOUTUBE video, I note that the piston in the middle does not move ... is that ok?:hmmm: |
