jules....have you seen any of the big ABB electric turbos in your maritime travels?

 

Oh, and don't get me wrong, I like the idea of this thread... its just those guys in the Coates video had me screaming at my laptop, spitting bits of the scrambled eggs I was eating for breakfast at the screen lol. All I caught from them talking was them saying, "we have the cure for global warming, replacing poppet style valves with our rotating Magic 8 *****!" /facepalm

New engine designs are fun to look at to see how they work especially since the ohv pushrod engine is what we have been 'basically' accustomed to since the dawn of time... I'd contribute more to this thread, but I don't even know where to begin looking

 

 

Most slow speed diesels use electric blowers to feed the motor up to about 70-78 rpm's at which point the "tip in" or boost threshhold for the turbo's is reached and the engine can sustain itself. The electric blowers do not use compressor wheels I don't think but I could be wrong.

How's this for lag, without those blower the engine would never get up to a high enough RPM in order for the turbo's to kick in.

 

I saw that Coates design for the first time when I was living in the dorms at ASU, which would be 2002-2003. Doesn't look like they have made much progress since then.

 

I'm looking for that engine design that has the pistons that travel in a circle, can't remember what it's called and searches for Rotary just turn up Wankel designs....

*edit - found it, called Oscillating Piston or Toroidal Internal Combustion. Trying to find a video.

I saw that one last night on youtube when I was looking up a link for the TCengine. Looked pretty cool. Makes me wonder what kinda of RPM it can do with all the centrifugal forces acting on it.

 

Heres a steam powered engine, it was in a diesel power mag. Theres one they make that puts out 860 ftlbs. @ 1 rpm.

i was reading in a mag the other day at firestone (gettin tire fixed) about a V6 gm is ging to produce that has twin turbos and either runs on 85eth. or something of that nature that will put more tourque to the ground than a 6.6 duramax......cant remember the name of it

 

If these engines are so good, why haven't we seen them in production? Coates claimed they have been in business for 15 years. Why haven't we seen anything like that...in a car, boat, airplane, etc?? No matter what people say, the conventional internal combustion engine that we know today is here to stay. The design is just too familiar and *RELIABLE* to let it go. Manufacturers will always keep refining the internal combustion engine with new technology......I just don't see anyone reinventing the wheel anytime soon by introducing an unfamilar engine design in a car. I guess the only exception to the rule would be the Wankel rotary engine in the RX-7 and RX-8, which has been pretty successful.
