New Boost Idea - Has this been done before?

[Schmieder]

Listen... Friend... "All Solutions... Breed NEW Problems..." As clever as the thought might be...you are forgetting the problem of RESONANCE. While you are investigating Volumetrics... try and get your hands on some of the writings by Nikola Tesla... and yes...everything physical as well as electrical is subject to destruction through Harmonic Amplitude. The fundamental problem with your theory is that you are forgetting what will happen to the relationship between the Valve Stem and the Valve Guide when being bombarded with so much concentrated sound energy. At the levels of energy you are suggesting the sound pulses must be raised to be effective enough to work... those sounds waves will generate enough energy to turn into HEAT...and add yet another energy dimension into the air stream that is disruptive to its movement. The sound wave you suggest using in time with the 6X sensor will accumulate elsewhere in the block and in particular... be added to the longitudinal vibrational forces in the crankshaft. The Harmonic Balancers on our engines can only absorb so much vibration before things begin to fall apart. So take a moment and consider these other forces in your equations.... Sometimes...less engineering...is more...


Oh...and to ask Ben a question predicated with words ladled in sarcasm such as, "Do You Understand?... Of COURSE you do..." is to reveal completely your lack of understanding that while you are only ankle deep right now in the waters of this little problem that you posit... Ben's knowledge of mechanical things plunders many more fathoms deeper than you comprehend at the moment. So... try not to SOYD so soon since coming here...while you find yourself temporarily on this Fool's Errand... and make nice with your Betters while you have the chance...

I feel my words are being misunderstood. I know Ben is a very wise individual when it comes to this stuff. I read from this site all the time, just never posted until now.

Ben, please don't take what I said as arrogant. I just didn't word it as best as I could have.

And your point about heat is a good point there. This is why I decided to post this idea. To get input from others. Better to dig around the science before endeavoring into design and construction. Which in this case rings all too true.

What can I say, I like to create and modify

So I hope nobody thiks I'm being arrogant to see past the truth of the matter. It is something I love. I plan on attending Wyo-Tech in SW PA in the next year. I heard it is a fantastic school for automotive careers. I'm planning to pursue more towards the high performance direction.

You also have to deal with the varying speed of sound as it changes with air pressure. You might even be wasting more power than you'll recieve since electricity for the sub isn't free. And with speakers in general being as inefficient as they are, a good chunk of that electricity is wasted as heat.

Yeah, it seemed a promising idea at first but now I can see it has many complications. The tuning and control would be a nightmare even if one could get past the physical limitations of any hardware that could be employed.

Ok, I'm off to sleep.

Merry Christmas everyone!

Not bothering me any:P Last night I was contemplating the advantage of my ear wax creating a vacumm in myear while using the "ear bud" head phones, and what its effect on the sound waves hitting my ear drums would be if I didn't have that vacuum in one ear.

This kind of reminded me of that, and the paper I wrote on emissions controls, which included the muffler. The idea was to use a speaker to send a negative wave of what would be coming out of the exhaust pipe.

If you want to mess with this idea, get a low hp 1 cylinder engine.

Oh, and my mind only goes so far. Usually when the numbers start flying, I stop:P

What you are thinking of here, is basically a diaphragm compressor.

Nothing new, definately isn't going to work with a speaker though.

I have never heard of one being coupled to an engine in order to provide boost, not saying it couldn't be done, but I'm sure there is good reason for that.

Stick with your normal, mass produced turbos and superchargers, you aren't going to reinvent the wheel here

[Superdave]

It's hard to comprehend how much air is being sucked into an engine. A sub woofer if you could get it to fire that fast (would have to move faster than tweeters) would not generate enough psi or volume to create any psi, let alone time it just right to get the pulse at the right time.


Much easier to just throw a real turbo on...

I work on high speed timing circuits on a regular basis, I really doubt you'll be able to get any sort of reliability out of any variation of this. Properly timing the pulses would be a nightmare considering all the variables involved.

[ForcedFirebird]

It's actually more of an equation and physics calculation
(combined with a little luck), but there have been instances where the timing of the pulse of the back of a valve snapping shut, can be directed to the very next cylinder needing that fresh breath of air. Taking a reading on such a manifold and it will be positive on a vacuum guage, but that is using the harmonics of the engine itself - much easier to time

This is why I referred to a pulse jet earlier.

I hope that isn't directed towards me. I quickly learned my idea won't work but still, sometimes you gotta go out on a limb to see. Dare to be different and one day you just may hit the golden prize, a patent that makes one filthy rich.

Many great ideas were once meet with scorn and distrust. And this idea still rests in the back of my mind. One day maybe I can make it work some how.

Another idea I had was to induce a standing pressure wave using various reinforced sound emitters. Tune the standing wave to sit a the valve opening creating a bit of higher pressure at the opening and a lower pressure in the combustion chamber.

Ehh, it's all speculative science. I just like to think outside of the box.
