Good morning all, It appears the norvels are back. One the glow site. a guy email. klondike [email protected] has a listing of engines and parts, the 049 and 061 are listed
as well as parts, the Davis conversion head fits these as well as the Cox 049/051. quality of the engines ??? anybodys guess but both carb versions are listed martin

Mr Cox

If you read the rest of that thread you'll find that they are not back at all, it is simply false marketing. It is most likely some guy with old parts and engines...

AMB

Mr cox you may be right he could have bought a bunch of salvage stuff a a lump buy martin

You, guys, are wrong. All the parts and engines I am selling come direct from the manufacturer in Russia. They are 100% original, not Chinese made.

Mr Cox

The question that has not been answered anywhere is whether these are old stock or indeed newly made parts?

Who is the manufacturer when Norvel as a company does not exist anymore?

Here is an excerpt from a press release.

We have a limited production and we would like to take it slowly. You can mention that Norvel engines and parts are back. They are 100% genuine coming from <st1:country-region w:st="on"><st1lace w:st="on">Russia</st1lace></st1:country-region>. Norvel engines used to be manufactured in a Russian military factory, but in 2003 the factory received a huge government order for a classified military item, which became the prime focus of the production. Norvel engines became “unwanted” and their production stopped. This year a group of Russian enthusiasts negotiated a deal with the factory and acquired the old stock and the equipment to continue production of this popular engine. The brand Norvel will change to NV. Most likely it will happen next year. NV stands for Novikov Valeriy – the initials of the inventor and the designer of these performance engines. The sizes available for sale are 0.049, 0.061, 0.074, 0.15, 0.25, and 0.40. The web site is under construction, but orders and inquiries can be emailed to: [email protected]

Mr. Cox, if you are into diesels, I can provide you with diesel heads for 049 or 061. This way you can convert your Norvel engines to diesel.

Mr Cox

Would that be made from Norvel/NV too, or is it from Davis Diesel or RJL?

klondike17

My Feedback: (4)

All my parts are from NV

Mr Cox

So NV are making diesel heads now?
What technology/design do they use?

klondike17

My Feedback: (4)

Only for 049 and 061. The price is $9.95

That NV is a real "renaissance man":

Mr Cox

That is a good price. I would still like to know what design it is?

klondike17

My Feedback: (4)

Sorry, I looked at the wrong price. The price for a NVdiesel head is $22.95. It is a contra-piston design with a lock bar. Since I made a mistake, I will sell it to you for $20.00

We also sell a diesel conversion (for $14.95):

Although primarily designed for Cox .049 and .051 engines, the assembly will screw in to the Novel .049 & .061 engines.

Bernie

Mr Cox

Hi Bernie, are those heads made by DDD, looks like the same design? Are you making any heads for the PeeWee?

I only know of DDD (of which I already have a few) and the RJL ones with an o-ring sealed counter piston. There has also been a swedish one with a traditional friction seal of the counter piston in the head, but these are not made anymore.

As for NV stuff I would at least like to know the construction before buying anything, is there at least a photo or something?

Cox International

My Feedback: (10)

They are the same as the DDD ones, which was unintentional.

We had sent a DDD sample to a machine shop and asked that they copy the combustion chamber but modify the outside to a 2-fin version (similar to our glow plug adapter), different screw and slotted to accommodate a regular Cox wrench. The drawing they made was great.

However, after sitting on the order for 4 months and not manufacturing them, we finally asked them to forward everything to a competing shop. The competing shop made them right away but, in the process, the mods were forgotten

When we received the finished product yesterday, I winced as we are not in the habit of copying other's designs. But it was too late to worry about the design and we listed them as is. Oh well, they are proven design at least

As to the NV one, no idea what it looks like, sorry.

Bernie

Mr Cox

Thanks for the quick answer Bernie, and thanks for your efforts with cox engines and parts.

The NV questions where directed at "Klondike"...

How is the contra-piston sealed,, with an O-Ring?

klondike17

My Feedback: (4)

An O-ring is utilized where the technological process doesn't guarantee a precise fitting of the contra-piston. In our case, it is guaranteed, thus no O-ring

Mr Cox

Could you please provide a photo or a sketch of the design?

I do not no of any current manufacturer that makes a conversion head with the common tight (lapped) contra piston. Instead they are gaskets supported by a counter piston (DDD and Bernie) or a counter piston with o-ring seal (RJL). There was a swedish product (in the 80-ties) with a traditional lapped counter piston, but these are not made any more as far as I know...

Hi Krister,

How is your 074 performing? I will post a picture of the diesel head later

Recycled Flyer

Don't Enya currently makes lapped counter liner/piston assemblies?

I know that they are not 'conversions' but it shows that its commercially possible.

AMB

Recycled flyer My enya 25 parts breakdown sheet does not show an O ring on the the contra and of course my Irvine 40 diesels ( factory head ) do not either, my personal preference
is an O ring Davis of course on his heads and a few others no chance of sticking, martin

Recycled Flyer

Hi Martin,
You will also find that all Team Race racing diesels use a lapped three piece head- they simply don't trust that little O ring at 30 000rpm!
