In your earlier post you state
(The rotors do indeed rotate at 2/3rds the rate of the eccentric shaft....BUT in the opposite direction)

Follow the directions that I stated this morning and you will find for yourself that your statement is misleading and completely false.

I made the original post to be of assistance in oil cooling. I am sure that there are some out there that would appreciate that creating a low pressure area on one side of the rotor will greatly improve oil circulation in the rotor.

Bullshit. I didn't say relative to the housings; my observation was relative to the JOURNAL. 2/3rd backwards relative to the journal equals 1/3rd net forward relative to the housing. This is really simple stuff...what part of it are you not understanding?

Your "assistance" in oil cooling is based on some break-down in your understanding of the engineering that went into this remarkable engine. The statements you made were patently false. Do you expect a free pass?

You say (Bullshit. I didn't say relative to the housings; my observation was relative to the JOURNAL. 2/3rd backwards relative to the journal equals 1/3rd net forward.)

You did not take the time to do the experiment if you did so you would not continue to promote your misleading statement.

I have designed a Wankel type engine that has the housing rotating clockwise at the same time the eccentric rotates twice counterclockwise and the rotor remains stationary as a pedal on a bicycle. This engine completes three power strokes for each housing revolution. The simple act of stopping the eccentric changes the functions to be the same as Wankels DKM 54 and fire once every revolution.

You do not have the experience to understand the complexity and you are basing your knowledge of others who also have not taken the time and effort to understand the complicated rotary principles.

Take a 8 inch diameter triangle and turn it in a 7 inch square and pay attention to the movement of the center as you walk it through one complete revolution you will then have a shallow beginning to knowledge about the Wankel engine.

There is no backwards motion in the Mazda rotary even when gears are applied to from the eccentric lobe to the rotor, all the motion is in the same direction. if you use spur gears you will need idler gears going counter to keep the motion in the same direction.

There is much room for improvement in the Mazda rotary.

The only thing complicated is the interaction between the medications your doctor has prescribed you! Please discontinue use and seek medical help. This is all I have left to say on the matter.

Blake thank you for your medical advice. I appreciate your concern.

I thought that I had a good understanding of the Wankel rotary engine after I had successfully made two different designs of machines for cutting and finishing the Wankel housing.

I realize that my knowledge was deficient when I attempted to gear the rotor to the e-shaft. I made five prototypes before I finally solved the problem. It is this hard earned experience that I am willing to share.

Thomas Edison was a great inventor because he was not educated to know.
When a person knows it all, the person no longer needs to pay attention.

There is a lot to learn from the simple experiment about marking the rotor on three places and marking the e-shaft on one.

By cutting a slot inside the rotor the rotor will have less weight, the oil will circulate and the rotor will have less interior pressure and the engine will run cooler. The proof that is in the pudding is in the eating. There is everything to gain and it takes only a little time and expense to try.

Alright, simple solution: Run a stock motor, record oil temps. Run a StarApex motor, record oil temps.

That is pudding worth eating.

That I am going to do but I will start a new thread on the project.

So... If dinosaur **** dries out into a semi-solid and over the eons gets hot and compressed into crude oil, then I'm to believe that a rotary engine uses heat and compression to turn it into a solid again ? So the carbon in the engine is really solidified ( not burnt as in combusted ) motor oil ? Can we up the compression some more and blow 1/4 carat diamond chunks out the back *** ?

I was wrong by saying that the rotor rotates one and two thirds to two revolutions each e-shaft revolution.
I now realize that a rotor turning two thirds of a revolution on a eccentric bearing that orbits the journal each rotation has a rotation that cannot exceed the journals revolutions.

Thanks to blake for the format of the following paragraph revised by Ken

The rotors do indeed rotate at 2/3rds the rate of the eccentric shaft, creating the appearance of a 1/3rd backward rate! This means that it takes 1080 degrees of eccentric shaft rotation to turn the rotor 720 degrees. The loss of 360 degrees puts the rotor in phase and completing 3 cycles. Thus, every turn of the eccentric shaft nets one cycle per rotor. HOWEVER, while the rotor *rotates* at two thirds of the forward rate of the e-shaft, it still *orbits* at full speed on the journal.

SIMPLE REVISED DIRECTIONS TO PROVE THIS POINT

Place a rotor on the back housing with the stationary gear. put the E-shaft through the rotor and position the rotor at the end of the compression stroke.

Make mark one in the middle of the rotor and another on the E-shaft at the same location. Now number two and three counterclockwise in the center of the trailing surfaces.

Turn the e-shaft one half revolution clockwise and the e-shaft mark will then line up with number 3. Turn the e-shaft another one half revolution and the e-shaft mark will then line up with number 2. #2 is now in position to fire.

Note that this all takes place with clockwise motion.

This confirms the fact that the rotor rotates at two thirds the journal revolutions while it is in orbit around the journal at full speed.

I have more to say in this subject on other issues than oil cooling.

Blake posted a sheet from Mazda on oil cooling the rotor. It appears impressive but it is the stuff that David Grimes hammers and has trouble picking up. I like engineering words like centripetal that sound impressive but have no substance. Oxford Dictionary “Moving or tending to move toward the center” It is my opinion that the oil is sloshed back and forth when the engine is running at low speed up to 2000 rpm. (In Jan Norbye’s book he mentions that NSU left a piece of metal in a rotor and that it did considerable damage to the interior of the rotor.) Between 2000 and 3000 rpm the oil is in a transitional state and I have read about there being erratic performance at this time. After 3000 rpm The centrifugal force creates sufficient gravity at the periphery of the rotor that the oil cannot escape and the rotor and the oil become unified as a solid.
From this time the rotor is balanced but the oil does not circulate.

This is the reason that I started this thread.
