What is a lavonia cell ..... 'lavonia' not in my dictionary except as a City in the State of Georgia (USA) ????????


ORIGINAL: torque wrench

I do not see where that is a Diesel. There is no lavonia cell anywhere to be seen, it has glow plug in it.
Wrong wrote, it shall be Lanova cell, it is a combustion cell or energy cell in the older dieselengine. I maked the Lanova cell with contrapiston to my 4 stroke engine. Search after the 4 stroke diesel engine in this forum.

I just got through test running my Magnum .30RFS after a diesel conversion. The engine itself has some kind of issue and won't hand start but it ran OK after starting. I have to tweak the compression ratio and make some changes to the lanova cell, but it works. It throttled well after adjusting the needles. Now, I have to go back to my OS FS-40 and make some changes to finish that one. I might get a video of one of the two running this week.

So someone get's a glow plug engine in the wrong diesel box and makes a huge profit on ebay. I wonder if the other box was used to sell a rare nitro enya, with a mysterious compression screw.

No, Enya actually offers this product. The part number is 41-4CD. Unfortunately there are no details available, so the rumors are flying, no pun intended. I'm going to take my chances by ordering one.

This is my OS FS-40 converted to diesel with lanova cell. It runs OK. I have too much compression and need to reduce it. That's an easier problem than increasing compression. I hope to get some tach readings tomorrow.
Edit: It has no rocker cover at this time because I haven't shortened the pushrods. The adjustment is at it's limit which gives proper clearance, but the adjustment screws hit the cover while installed. It'll be back when I'm done.

The Magnum .30 RFS still has valve sealing problems that I haven't sorted out. It runs but is inconsistent and will not hand start. I might try the other one I have to see if it's any better.

treedog, If Drone is on the front of the crankcase it the MkII version with ball bearing. If Drone is on the side of the engine it is the first version with a plain bearing. Needle valves and other reproduction parts are available from AEROELECTRIC email [email protected] specify the version Drone you have when ordering a needle valve as they are different from the plain bearing and ball bearing models. Also a variable compression head is available from Aerodyne. I have been running 3 of these late 1940's diesels with fixed compression heads and the Aerodyne variable compression head.

Greg -

Nice picture of your 4-stroke diesel conversion. Did you make your Lanova cell or buy it?

I made it on my lathe. This one turned out very nice. The first one was so, so. The screw and contrapiston shot across my townhouse complex as the threads failed.

I ran my OS FS-26 yesterday on diesel. That one worked very well, and am happy with the results. The .40 still needs some tweaking so no tach readings yet.

[link=http://www.edfinfo.com/x/temp/FS-26SD.wmv]FS-26SD Video 3.7Mb[/link]

Here is a video of my OS-FS26 diesel. It turns a Graupner 10x6 at about 8700 and idles at 3000. I saw some readings at 91-9200 but it could use some tweaking of fuel mix. It burns very little fuel.

Thanks for the video, Greg - that 4-stk diesel sounds great.

In general (not in this engine) I wonder if threads on the inside of a Lanova cell could encourage pre-ignition. Hot, sharp edges.

There are no threads inside the lanova chamber. But I do seem to think detonation is a problem. Jens says reduced ether will fix that. I'll be mixing some fuel today. You can here it knocking a little in the video, especially during throttle up.

I ran the 26 again after some changes. No new fuel, but it tuned much better today. It ran the 10x6 at 9100 and the 9x6 at 10500 RPM. This makes for about .29HP in either case. I think it can do better.
