Wankel Engine Pams

#1
Gents..

An aquaintence of mine has aquired one of those gensets that used to power Cymbaline - the one with the Wankel engine.. We spent last night extracting it from it's green box, and apart from some external corrosion, the beast seems in OK condition.

The current plot is to use it as the basis of a working model Deltic Locomotive engine.. OK it's not a Deltic, but it's the right shape and should sound sufficiently different..

The only problem is trying to make sense of the mass of wires etc..

Anyone any pointers to a schematic and/or manuals?

The Mazda RX8 has a Wankel engine, would a Haynes manual give you any pointers? Or will they be completely different beasts? I honestly have no clue when it comes to engines!
 
#6
We havn't found a makers name yet on the engine.. don't think it's a Mazda - it's only the size of a wastepaper basket..!

Yea, maybe "mass of wires" is a bit of an overstatement, however the thing has an electronic EMS, and it would be useful to find out what it is, before we go poking about too much..

Have you ever considered marriage to an older man? An occasional update would be fab if you can be arsed. On the Deltic. Not the proposal.

Sounds like the Wankel Owners lot will be the ticket but if you are stuck on the leccy bit, this lot of anoraks are dead helpful. I restore pre-1930's engines and have had a guy drive 50 miles to help out in exchange for a beer and some sandwiches. They like a challenge that runs above "Why wont my Lister D1 start?"

Heres a couple more.

Another good resource is to write to Stationary Engine mag with a pic and a question. Some of the proper old anoraks dont do the internet but they all read the mag.

KELSEY Magazines

Finally, if you are near Manchester or in the SE there are engine museums staffed by expert enthusiasts who are always helpful.

The NSU RO80 from the seventies had the Wankel engine -- could it be the same unit that was used in this application?
Until Mazda came along that was the most visible application for the Wankel in the UK. It's a small (and fairly weird looking) motor. This is a cut-away.

When I was a kid, a friend of the family was a Ro80 nut as well as being a caravanner (he sold them for a living, had a dealership near Sennelager). ISTR he blew out an engine while touring round France; had the new engine shipped and fitted; ignored the running-in guidance; and blew out the replacement engine on the way home...

wankel engines are very efficient, but the tips was the problem, something i believe they mastered with the Mazda. Would love to have a good running wankel engine in an open-engine-bay hot rod

RX rotor tips tend not to last much beyond 100k miles (if the info from a mate with 25 years of spannering experience is right). I'd rather have Chevy or Mopar under the bonnet...but the principal of wankel engines is fantastic.

true, but the tosser in me want to say "belly button motor" when i see chevy or mopar used in that context....

then again, I do love my Y block :lick:

back to wankels, 100k, thats not too bad, and the capacity is larger, isn't it? doesn't a 2 litre wankel actually equal a 5 litre conventional engine?
