Developing a Ryger
Is Ryger a fairy tale? With those phenomenal properties it may look like it and however some people does call it that way, it is certainly not. Initially it was Mr. Hendrick Gerrits had not meant to design an engine with more power, but to make a clean 2 stroke which should make the 2 stroke engine more important again. At that time I was looking for more power and therefore initially less interested, but along the way that changed when also Hendrick himself was pleasantly surprised by the high power including the corresponding speeds. At that time it was still the question of where all that power came from, until you are seriously searching for an explanation. We from Ryger told everything we have experienced in the past and of which we became enthusiastic to tell around. May be we better should not have done this, because many people won’t believe this, which we fully can understand.
The reason why it took so much time to get the production ready for an engine, which we can guarantee for 100% is:
1. We do not have a 100-man department for development behind us, like Aprilia or Honda does have.
2. It is also not a development of an existing two stroke engine, but a completely new designed principle. This makes it much more complicated, than a simple development, on what many other technicians have prepared for you in many years before your time.
3. And we can’t spend more hours than we have done till so far over the years. So of course this took some time, and afterwards more than we could imagine, for which we are very sorry !
At this moment, there is no reason, not to be proud of the result we have achieved till so far. Now that we are going to answer all the wishes of the opponents one by one, the strong wind from several people will go down. And with so much strong winds of the most famous two stroke experts, the result will only be more beautiful for Ryger. For there will be a time, they will have to acknowledge that they are totally wrong.
In the meanwhile, we are continuing to highlight parts of the Ryger publication that will be very surprising to most. I've already mentioned (on forums), the for a two stroke strange interdependency of the exhaust pipe and the temperature (physics as I told before) of which both items I will come back later. First I will start with:
The connecting rod
The start with the connecting rod length is because it is labeled by the experts as the most impossible good detail. Extremely high lateral forces, which will be impossible to use! Yes for sure in a normal twostroke I agree, but Ryger is not a normal two stroke, so I disagree for a Ryger engine. The reality for a Ryger is completely reversed, the shorter the conrod, the greater the piston acceleration and the better the Ryger principle works. Longer conrods have been tested, but the result got worse.
Lateral forces
The disadvantage of a short conrod, such as the lateral force is rising. Ignoring an offset piston pin the highest forces for the Aprilia with a 120 mm conrod are at 26° atdc and are about 1796 Nm or 183 kg. For the Ryger with a 90 mm conrod by the same pressure it is 2404 Nm or 245 kg, so 34% higher.
Special Ryger influences
In a normal 2 stroke the lubrication is mixed in the fuel and because less lubrication is better for the 2 stroke process, all bearings under the piston are lubricated very minimal. So when the engine has to made maximum power like in a racing engine, the bearings in the conrod has a real short life. This is one of the most important differences with a Ryger were those bearings last much longer. And also the higher lateral forces are much less serious in a Ryger engine due to by far much better lubrication.
1. Because the crankshaft is rotating in oil and spread out this to the downside of the piston and cylinder wall. The lubricating looks more like a 4 stroke engine.
2. Beside the Ryger has no tilting effect of the piston, it has been eliminated for almost 100%. That is why the lateral forces are far much better divided over the surface of the upper and downside of the piston.
End conclusion
In a Ryger a short conrod is the best solution and is certainly not what is told by the experts ‘ridiculous and totally impossible’. In fact it is more full the opposite situation. Despite the short conrod, this part will show significantly less wear in a Ryger in comparing with a soon old-fashioned 2 stroke !
Next chapter ‘the piston’ to be continued !
