Re: New Engine Design

Looks like a load of crap to me. What does he mean the motor is doing work when it was turning over with the compressed air. It wasn't doing any work, the air compressor was doing it all. If it's such a miracle motor, why didn't he just hook one up to a load and run it?

Actually that's a stunning example of efficiency, the only problem would be to get it to unwind at high rpm, that is if it can truly be made to work, I too look @ this with extreme skeptism, if true it would be a important as the missing link............. now if your looking for Detroit to get behind something like this it wont happen, they would have to throw Billion's of dollar's in investment's down the drain, i mean who would buy any conventional motor with something like that around......

Re: New Engine Design

I am very sceptical, but I have sent the video and web address to our Technology Director and another Senior Propeller-head. The second guy used to be the President of SAE and VP of engine devlopment at Cummins. He has a very open mind and is working on another weird engine technology right now so he'll give me a dependable and educated answer . . . The website has some better pics etc.

That sure was a very small output shaft for so much power.

Re: New Engine Design

first thought is I dont have an air compresor on my car
second thought is the output shaft is way to small for that kind of HP.
seems as though its just another wankle, lots of promice little delivery
we'll see!

Re: New Engine Design

I agree on the shaft size, but to be fair it is a prototype and his calculated torque could be a max as opposed to an actual. Wankel's issue was primarily fuel efficiency. They worked and had a very good power to weight ratio. This thing is different in that it has pistons etc. I remain super duper sceptical, but I am trying to keep an open mind . . . A lot of people don't believe what our engine's do, and I know they do what we say, so . . .

Re: New Engine Design

Ok I watched it again, at one point he says the front half is 32 cyl and the back half is 32 cyl so its 64 cyl. then he starts useing pulses instead of cyl then "about 32 pulses" then it only has one donut shaped cyl.

To me he does not agree with himself, just a used car salesman.

I do think there is room for improvment on current designs, just look how far we have pushed for speed, HP, fuel economy. I still think with some electronics one could eliminate the need for dino fuel completely. We gots to keep an eye on it.

Re: New Engine Design

Hey rwise, watch the animation on the angel site - shows how it works. What he says on the site is that it is equivalent to a 32 cyl. 4 stroke diesel. I can easily see how it works, and generates so much torque. But, displacement is displacement. The same displacement requires the same volume of fuel regardless of the configuration. The weight savings would be good in some applications, but not all. Heavy equipment, tractors, etc. need to be heavy. It is a very interesting engine, though...

That was true in the old skool days. But you're not considering efficiency and friction losses.

Still true. Air & Diesel/Gas still burn in the same ratios regardless of efficiency or friction. More net power can be generated, though. Wish I could see the prototype up close...

Re: New Engine Design

How come my engine doesn't consume the same amount of fuel regardless of the load I put on it? The displacement never changes....

Even in our most efficient current engines,only about 20% of the available energy is utilized.The rest is either excess heat or friction,and of course, the fuel that goes out the exhaust without ever having burnt.
It seems he licked at least part of the heat loss by having the incoming fuel cool the engine.There may be more.

That's the part I was getting at. The fuel cooling the engine is similar to a Wankel design.

Don't getme wrong, I think the guy looks/sounds certifiable. I was merely dabbling in theory.

Re: New Engine Design

There's a couple of fundamental issues that you guys are confusing here . . .

First, Diesel engines operate at a very wide range of air/fuel ratios. It is one of the most significant reasons they are more fuel efficient than a gasoline engine (Otto cycle): no intake air throttling, actually no "throttle" at all.

The answer to Frogger's question about displacement and fuel quantity is within that throttle story as well. You can sorta think of any throttled engine as having variable displacement as it chokes off air so that you can maintain the 15:1 ratio required of Stoichiometric Gasoline engine as we technically refer to the Otto Cycle engines in our cars and boats. At idle the throttle is almost completely closed and a 5.7 liter engine may only get .5 liters of air for example . . . There are some lean burn, throttled engines, but they are almost all turbocharged and have not made it into passenger cars and boats yet. Huge Natural Gas engines yes, 350s in boats, cars, pickups, no.

Also thermal efficiency of diesel engines is hitting around 40% these days, and throttled engines (lean burn) are getting very close at WOT. Throttled "stoich" gasoline engines on average are pretty close to rolmop's 20% number when you evaluate them over an entire duty cycle i.e. start, stop, idle, cruise, full load etc. I know this always makes heads spin, but throttled engines get their best fuel efficiency at WOT, and they are at their worst at idle. Please don't confuse this with hull efficiency. Waaaay different topic and it is the reason that fuel economy with a planing hull is best at idle . . . which, of course, sounds contradictory to my throttle statement, which is factual no matter what Silvertip says . . .

I think we're talking about different things. My answer to this would be that your engine does consume the same amount of fuel, per stroke, and that a higher load simply lowers your net power, thus requiring more cycles (and thus fuel) to do the same work.

 

[RubberFrog]

Re: New Engine Design

But the fact is that it does not consume the same amount of fuel per stroke. The load determines how much fuel is necessary to complete the stroke.

Re: New Engine Design

500 HP weighing in at 25lbs. Not a lot of waste having to move the engine too.

Perfect for my mower. I need 500hp in a small package.
Why did he not have it installed on some vehicle of sorts. I'd like to see a video
of a D-9 pulling trees with that engine under the hood.
Website reads good......but, no applications video's.

Re: New Engine Design

I have read through some of these posts and I dare say some of you need to either read something about engine theory or else take a refresher course. You postulations are giving me a headache.

That's how I feel when I listen to you guys talk about money management (or worse- investing!).

Re: New Engine Design

I invest in my boat---talk about unsinkable earnings!!!! Plus the salesman told me it could only increase in value!!

Re: New Engine Design

SuperNova,

I've been thinking about your post above. You should probably identify who you think is full of carp, so those that aren't will not be mistakenly disregarded
