Experimental Rotary Engines: Model 32

This follow-up to my previous videos summarizes the current design for the benefit of those that are experimenting with Model 30 based engines. Model 32 is not yet finished but most of the mechanics are in place. It's been dry run & tested for compression, friction & wear. Performance so far is superior to Model 30. Completing the control electronics & firmware will require more time.

Model 32 is similar to Model 30 (previous videos) except that: the rotors are steel lined with graphite; the vanes pivot (rather than slide); vane engagement is electronically controlled; seals, accuracy & fit are improved; parts count & reciprocating masses are reduced; rotor phase angle is adjustable to provide expansion ratios approaching 30:1; compression ratios are adequate for burning vegetable/diesel oil using direct fuel injection; the Lexan cover is replaced by a dimensionally more stable aluminum reinforced plate glass. Fins will be routed into the exterior body as needed for cooling. I should finish evaluating Model 32 by fall '07. The next design (Model 33) inherits much from Model 32, except that it uses 1 rotor & 2 vanes.

The purpose of this open source program is to develop more fuel efficient ICE's capable of operating on a variety of fuels for the benefit of our environment, our economy & our future. This material is offered freely in the hope that it may be useful & inspiring to tinkerers world-wide wishing to improve Internal Combustion Engine technology. -Dave

To all you knockers! What have you ever developed ?? Bugger all I'll bet ! Big with the mouth aint you? If you haven't got anything good to say about some one trying to improve tings keep your Fucking big mouths shut! Ass holes!!!

Great work! Keep it up!

@jcisbell very well said.

People that criticize something just for their own perverse pleasure are just an insignificant fact of society. They are to society what waste product is to the human body. Just try to not let any stick to you! :) and ignore the rest.

Nice machining...

Peak Oil ha ha ha

What kind of efficeincy does this engine have? And whats the rev range?

[Elevationary]

This has to be the best Engine i have seen so far with limited Friction.....

@den2003 lol you make it sound like Wankel invented the eccentric shaft. The eccentric shaft was probably invented shortly after someone decided they needed to combine a wheel and leverage. Assuming leverage was discovered before the wheel (since it is a more basic concept) I can conclude that the eccentric shaft was invented shortly,in the grander scheme, after the wheel. The Wankel rotary engine began life as simply a rotary pump. It was then modified to pump air and fuel instead of water.

@fatqwert200 Weight becomes an extreme issue when you're trying to lug gallons of water around.

@TheCommuted that may be true but there is still no2 or NO as a byproduct but i think someone shold make a catalist that can breakdown the other byproducts and recyle them into a tank of water to create a liquid exaust where it can be treated: ie for normal petrol cars get me

Very nice work! The World needs more people like you! Keep up the good work! Well done!
