[2stroke] Ryger engine

So I assume by now it is safe to conclude that the performance figures stated are a no go for this engine. Anyone?

Why bother with the homologation if there was no hard data to rely on? or was there?

Still no more news about engine problems. Still not solved yet , lubrication? reliability? no efficiency? in waiting to read you

Perhaps Ryger should have made the first motors in a larger, Texas-sized displacement.

Therefore, the reciprocating components would have been larger, inherently stronger, & dependable ?

With a larger capacity, IF the " new design " has greater efficiency, any performance benefit would have been amplified without needing astronomically increased RPM's.

Creating a new variation of an old product to fit within an existing, established market is a tall order. A target market controlled by a politicized bureaucracy almost guarantees success will be met with proportionately greater troubles, hassles, hoops to navigate, & expenses better utilized for actual production.

I say :

1. Develop a new idea.

2. Create, build, test, and prove the product.

3. Let the market do the rest.

An old cliche' about mousetraps applies.

Creative genius does not seek the rats' approval.

I don't agree with you, ambike.

The Ryger engine is supposed to get power at high revs, so a small engine is better.
As you said, it's better to start easy, so single cylinder is good.

If you claim to do better, you need a benchmark.
With an engine working at high revs, you can exclude the MX. The karting seems pretty good to start the fight and the hard work.

Ryger only developed a new engine. it's useless until you put it in something.
But you can put it in many thing, it will be the job of constructors then to create a new finish product with a ryger engine.

When the ryger engine will prove its superiority.

No reliability and no superiority.....
Nothing has been proved, after almost a year!
No power curve or race wins.
It did not even start once in a race.
Nothing at all.
Are there still any believers?
You will surely be disappointed.....
Bluffing has never been a good thing.
And yes, the market will do the rest!!

So, good engine for the GECO.

As you say Jan
"No reliability and no superiority.....
Nothing has been proved, after almost a year!
but must adlit that it sound quite mad that some guys who are on here frequently could just implicated on an engine design which was just make for doing the buzz on internet or on the two stroke planet!!
For me the concept could run , (i said the concept!!)but for me with heavy modifications and not yet with 80%cleaner. So reliability yes possible, superioriy? to be proved.....

With the far too short 90mm connecting rod they have reliability is near impossible.
This is a very big mistake....
It shows the designer has no idea at all about engine design.

Cool down man , who cares about the market , and who cares about the unbelievers point of view .....

some need truths , some like dreams , the story is not ended ryger - [2stroke] Ryger engine - Page 14 809262

You could say: the designer should go back to school and learn to read and calculate!
All documents about 2 strokes say that the ratio is about 2.2 and not 1.8.
To many approximations for this engine.

Yes yes who cares about too short rods or anything else really...

If we join hands and dream together engines will fall from the skies (along with naked ladies) revving to oblivion and making a thousand flying horses...

Not at all Koenich, it only took some more time, once again be patient!

Fortunately, most people wait very wise patiently.
Conversion from prototype to series production takes time, ask any manufacturer.

Im still waiting for visitors from the future to come back in time to bring the secret of eternal youth but every day my hair gets grayer and my joints hurt more sitting here waiting...... Perhaps it is time we moved on and get back to reality where the laws of physics prevail and pipe dreams end. Jan is right. There is nothing in the design or the claims that has been proven or even given us a glimmer of hope. Enough said.... ryger - [2stroke] Ryger engine - Page 14 629615

There seem to be some slight reliability problems Howard
Like seizures, and maybe nikasil flaking off the piston....
Nikasil plating a piston somehow looks like a bad idea to me.
As it gets far hotter than the cylinder!
Really nothing to worry about.
Except for the one that pays the bills!
50 engines in stock since december.
And not 1 sold.

Suivant les infos de Jan les problèmes semblent venir de la fiabilité du revêtement de la queue de piston: mauvaise tenue du Nikasil. Solution (suggérées) pour corriger le Pb:
- Un autre revêtement...????quoi???
- Un autre fournisseur de revêtement
- Un autre matériau du piston: alu silicium moulé ( c'est peut être déjà le cas).
- Réduire le jeu piston / alésage de guidage qui semble important: 0,15 à 0,20 mm( pour meilleur échange thermique).
According the informations from Jan, reliability of the Nikasil coating is bad on the piston tail.
Suggested solutions to correct the problem:
- Different coating, what?
- Different coating manufacture.
- Different piston material : alu silicium ( maybe it is)
- Close the play piston/bore to improve the thermal exchange, according the drawings it's seem very important: 0,15 to 0,20 mm.
I think Ryger will solve the problems. ryger - [2stroke] Ryger engine - Page 14 809262

Merci pour la traduction en français. ryger - [2stroke] Ryger engine - Page 14 771973

ryger - [2stroke] Ryger engine - Page 14 980796

DLC coating ( according to the piston material ) would better fit than nikasil ryger - [2stroke] Ryger engine - Page 14 809262

le traitement DLC ( selon la matière du piston ) serait plus approprié dans cette situation , du moins je le crois !!

.

High level 4 stroke engine pistons are "black coated", I dont't know exactly what material is, low friction carbon mixture?
Les pistons de moteurs 4t performants ont souvent un revêtement noir, je ne sais pas exactement de quoi il s'agit, une couche anti-friction à base de carbone?
Dan

Certains pistons 2temps aussi mais c'est pas un revêtement "magique", ça améliore juste un peu le frottement alu / Nikasil..

Le problème du moteur Ryger kart est que le guidage de la queue de piston ne fonctionne pas comme un piston standard avec un segment dans un cylindre mais avec un joint fixe sur une tige coulissante.
Système différent de celui du brevet qui était classique, piston alu dans cylindre possible Nikasil.
The piston tail guiding is not a standard design whith an aluminium piston and a ring in a Nikasil cylinder like in the design patent, but in a fixed seal on a sliding rod. This is different on the Ryger Kart engine.
Dan

Finally a Ryger engine has been tested on a dyno.
47HP.
Much more than expected, although 23 HP less than originally announced.
But: after half an hour it broke down.
Also much more than expected....
If it ever will be reliable remains to be seen.
In the meantime it is far better to buy a 'normal' engine.
About the same HP and fully reliable.
We will be told, again, to be patient.
Anybody still interested?
Expect greatly reduced prices in the future......

No , not patient , just try to be kind , if you can !!! , you argue like a old jealous man ryger - [2stroke] Ryger engine - Page 14 584741

Tu rigoles ou quoi? Tu sais à qui tu t'adresses? Lis un peu ça et tu verras que tu n'a pas affaire à un rigolo. S'il y a bien quelqu'un qui sait de quoi il parle c'est bien lui.
