Tentpeg Posted February 11, 2008 Share Posted February 11, 2008 Somebody was having a clear out recently and threw some OS Glow Plugs Type RE in my diection. The information on the pack says that these are specifically for the OS Wankel engines. I have about five of them so does anyone know if they are useable in any other type of two or four stroke engines or should I just chuck 'em away?Regards,Tentpeg.

001 Posted February 12, 2008 Share Posted February 12, 2008 Hello Tentpeg, these plugs are long reach and probably a 'hot' plug to allow for the relatively long 'timing' of the Wankel engine. That is they retain the heat in the filament. They look similar to O.S. 4 stroke plugs. But I think that as they are quite expensive and not easy to come by I would put them on an internet auction site. Quote Link to comment Share on other sites More sharing options...
Tentpeg Posted February 12, 2008 Author Share Posted February 12, 2008 OK Richard,Many thanks for your advice, I'll probably do that.Regards,Tentpeg. Quote Link to comment Share on other sites More sharing options...

Doug Ireland Posted February 14, 2008 Share Posted February 14, 2008 Does the Wankel engine have three plugs? I was wondering because it has that triangular shaped rotor. Quote Link to comment Share on other sites More sharing options...
001 Posted February 14, 2008 Share Posted February 14, 2008 Doug, only one plug, the rotor sweeps round past the inlet, plug and exhaust every revolution, there are three 'chambers' between the rotor and the figure of 8 shaped casing which change shape as the rotor turns, so each chamber receives mixture, compresses it, the plug ignites it, it pushes on the rotor, then the smoke goes out of the exhaust port. For each revolution the other two chambers are going through the same process at the same time. There are a few animated drawings on the net that explain the process.

Tentpeg Posted February 14, 2008 Author Share Posted February 14, 2008 Hi there Eric Bray, Thanks for the info on Malcolm Fisher. I've found his profile, but don't know how to actually contact him??I can't seem to find any direct post from him where you suggest. Any ideas?Regards,Tentpeg.

Tentpeg Posted February 14, 2008 Author Share Posted February 14, 2008 Hi Eric,Doesn't work for Malcolm Fisher as he has no email address or contact details listed, so I guess he may see it here, if at all? If I don't hear anything in a week, I'll probably stick them on eBay with some other bits and pieces that I have. Thanks for the suggestion.Regards,Tentpeg.

Doug Ireland Posted February 15, 2008 Share Posted February 15, 2008 Richard, thanks for the info. Are all rotary engines the same; ie, single plug? Quote Link to comment Share on other sites More sharing options...
Tentpeg Posted February 15, 2008 Author Share Posted February 15, 2008 I didn't realise that anyone else, other than OS, made a rotary engine for models. Tentpeg. Quote Link to comment Share on other sites More sharing options...
001 Posted February 15, 2008 Share Posted February 15, 2008 Doug, a rotary engine is a piston engine where the crankshaft is fixed and the cylinders rotate, for reasons of balance there has to be a number of cylinders, each with its own plug. Gnome & Rhone etc. As fitted to several WW1 fighters and 20's trainers.The Wankel is an engine with a rotor inside it. There have been Wankel engines with more than one rotor, for cars (NSU, Mazda RX series etc), full size aeroplanes, generators, but these are stacked together end to end with a common 'crankshaft' and each rotor chamber will have its own plug.There are other, mainly experimental, engines with various shaped rotors inside, but each will have its own ignition arrangements.

Doug Ireland Posted February 15, 2008 Share Posted February 15, 2008 Richard, semantics aside; we were talking about Wankel engines. I do know what a "Rotary" engine is. Quote Link to comment Share on other sites More sharing options...

001 Posted February 18, 2008 Share Posted February 18, 2008 Doug, we started out discussing the plugs fitted to Wankels, which is commonly known as a rotary engine, the answer as far as I know was one per rotor.I honestly thought that you later were then referring to Rotary engines as such, I apologise for any misunderstanding.There have been a few other Wankels made for model aeroplanes, but in small numbers. And some drone engines for targets. There is an interesting model engine from the USA which has been sold for several years, difficult to classify, but looks from the outside like a Wankel. (This one has two plugs!) http://www.ericksonmotors.com/technolo.htm Quote Link to comment Share on other sites More sharing options...
Tentpeg Posted February 18, 2008 Author Share Posted February 18, 2008 Doesn't really matter what the correct terminology is, the simple fact remains that I still have four OS type RE plugs and they are suitable for an O.S Wankel engine. Anyone want them? Tentpeg. Quote Link to comment Share on other sites More sharing options...
Tony Patman Posted February 18, 2008 Share Posted February 18, 2008 Tentpeg, I hope you find someone who wants your plugs. Indeed, Ebay might be the place for them otherwise.Richard Bond wrote (see)There is an interesting model engine from the USA which has been sold for several years, difficult to classify, but looks from the outside like a Wankel. (This one has two plugs!) http://www.ericksonmotors.com/technolo.htmNow THAT is intriguing. Please may I have one to play with? In fact, it's so interesting, I'm going to start a new thread about it. It's not a Wankel, but crikey, it's cunning.Incidentally I always thought that a rotary engine was a radial engine in which the crankshaft was fixed and the cylinders rotated around it...
