Rotary Engine, despite the difficulties to make it, Mazda still use it for cars and vehicles.

The most fascinating advantage is that this type of engines transfers the power of explosion of fuel directly to rotary motion of axis.

math's rotary motion has stand with time, however, there are many other inventions to challenge this type.

Let's ignore the physics and engineering part, by just focusing on the rotary part and the part surrounds it.

Can you explain it by Mathematics?

What is happening? The end of the link is supposed to be math instead of math

Why automatically it is changed?

hi George,

There is an automatic word swap 'censor' that changes certain words that are thought to be rude in some way.

Anyone who wants to click the link can first save it and then substitute back the right word instead of the word math.

It's a nuisance but it's there to protect the site from abusers.

Edit: Just tried that and here's your picture:

Thanks Bob!

The old rotary engine is beautiful in theory, but has many engineering flaws that make it vunerable

Why wan-kel rotary has no future

Hence there are many geniuses inventing new form of rotaries, for example:

a new rotary engine vs wan-kel

The rotaries fits in the chamber quite neat, huh?

How are they fit into the chambers and how to determin the axis?

These are very interesting math questions.

It is based on cycloid, traditional technology used on watches.
