Emission Controls - Technical Thread

[mydauphin]

On a totally different but related subject... I added some old diesel I had lying around (it was still good) but was mixed with a little motor oil. About 1/2 gallon motor oil to 15 gallon diesel. My truck seems to run fine on it. I remember there was a system that used take some of your engine oil and mix with diesel and burn it. You would then add more motor oil in engine. That way oil never got old. What effect would this have on injectors and emissions.

"What effect would this have on injectors and emissions."

Go to the DD site , they have very graphic pictures ob engines ruined by using waste oil as fuel.

Even IF you could get it clean enough , remember waste oil os contaminated with metal particles , acids and carbon (why its so black).

None of this wicked stew is useful as fuel or oil till cleared of all the gunk.

The amount of electrical energy needed to separate H2 from O is equal to the thermal energy from the explosion, so the gain is zero. In a future world without oil, this principle will be used to power aircraft. For automotive and marine use, electricity will do, but airborne vehicles need something with less weight and must carry enough energy for long distance flights.
The electricity needed for the electrolysis of water can be obtained from a number of sources like sunlight, wind, nuclear or the tide.
If you live long enough, you'll see it all happen....

I have read that a faulty pressure valve on a water heater can also cause high temperature extraction of hydrogen, with disastrous effects however. I don't understand why we are not using wind and solar to produce hydrogen. That could heat water and homes directly or in fuel cell technology. Oops, sorry for the digression of the thread.

We use a waste oil furnace in the shop. It keeps us warm in the winter but requires a bunch of maintenence each month and uses over 1.75 gallons per hour. The injector will clog if not cleaned about about every 200 gallons. We use a three stage filtering process to remove solids but contaminants don't burn all that well. Brake fluid and antifreeze really screw things up. I can't see a high efficiency diesel injection system lasting long using a waste oil mix.

I concur with Fred and Eddy's thoughts on blending old oil with fuel.

Look at it this way: You change your oil because the old oil has picked up too many contaminants that can't be filtered out. They'll be just as nasty, if not more so, if you move them from the oil system to the fuel system. If it were possible to fit on-board equipment that would remove these contaminants, it would be much more economical to use the revitalized oil as oil, rather than as fuel (which is always much cheaper). But since the equipment to do that is only economical on a refinery scale, we're stuck with storing our waste oil in jugs or tanks until we find a depot that can send it back to the refinery for re-processing.

This would not solve all of the old oil's problems. There would still be 'shear' breakdown and thermal breakdown issues even if you centrifuged all of the contaminants out.

Not sure I'mgoing to be worried about diesel or JP5 in 1,000 years.

The problem is the metals in the lube oil are sometimes held in suspension, sometimes bonded to the oil additives detergents..

The waste oil burners in most truck repair shops probably dump more in one day than 5 coal fired power plants , from the metals burned and vented into the air.

This is what I had in mind, see post 54.

The controller is an important part. It must regulate the current in the vessel and has to prevent operation while the engine is not running. Without it, the intake manifold would be filled with only oxygen and hydrogen, so 5 times more energy content than any air/fuel mixture , which is much more than even the sturdiest engine can chew.

The vessel needs a trickle of water, otherwise the salinity would rapidly increase. I think this also works in inland waterways: there are always pollutants the make the water conductive albeit less than seawater, but the controller will take care of that.

Google for world crude oil reserve Fred!

Confirmed reserve 991,8 billion barrels.
World production 68,4 billion barrels.

My calculator says 14,5 years. Where are you gonna get your oil for the other 985,5 years?

[mudman]

Ammount of oil in reserves/Oil production = years of oil left.

A simple calculation, and makes sense. We would really have to put more into it to get a better number.

The known ammount of oil reserves is based on what we can produce today, with current technology. It is also considered reasonable to produce, economically. In other words, all known oil reserves are based on the easy to get stuff. There is at least 10X's the real known ammount of oil than the numbers given for "known reserves".

Technology is constantly advancing, we are drilling deeper in the oceans, we are starting CO2 injection and waterfloods, gas lifts, controlled burns. Fields that we thought were dry 10 years ago are now producing more than when they were initally drilled.

In the 50's we could drill maybe 5000 feet. Now we can get deeper and into different sands. We can drill directionally now, instead of a straight hole. I wonder what we will be doing 15 years from now.

When we begin to run out of "known reserves" the price of oil will go up. We will simply go for the harder to get stuff, and it will cost more. The price will begin to get so high, that only the elite will be able to afford it. When that happens, we will be forced to an alternative energy. Eventually, oil will fade away (not in 14.5 years, probably not in 145 years). When this happens, there will still be recoverable oil in the ground, just no one will want it, because it will be too expensive.

So in reality, the earth will never run out of oil in the ground, it will just become dumb to drill for something that no one can afford. I certainly do not believe that doomsday is in 14.5 years, not from the data that I review.

Until someone comes up with a better energy source, oil will remain king. I certainly think that we need to start working on alternative energy now, but we do not need to force it on people yet.

Not you too...Danger - The aliens are invading headed by kistinie, with their water to hydrogen/oxygen powered by the alternators... It doesn't work....
Try this thread Bedini motor and other joe cell playing with energy conservation

[mydauphin]

If we run out of oil... We are so scrxxed.... No fiberglass, epoxy, aluminum, steel, forget about gas and oil, you better grow your own potatoes..

Seriously, you can make oil out many things like coal, which we have plenty of. Also biodiesel does work. Then we have other fuels like natural gas, methane underwater.. The problem is environmentalist passing up on a lot of non-renewable energy when they don't know what they are talking about.

Example, I was helping my daughter with college science class, they list nuclear fuel as a non-renewable energy. Guess what, it is renewable, it is call a breeder reactor, but they don't explain that in school.

And like that many others...

and:
that was not really meant to be a statement?

nuclear fuel to be renewable?

Lets stay on topic.................please..............

The stone age did not end because we ran out of stone, or worse still, fearing that we were in danger of running out, the rulers of the day forbid to use stone for tools. Instead, the stone age ended when we found something better than stone with which to make tools.

CDK,

Try to keep in mind that splitting water is a energy net negative process; you always get less back than you put in. Water is burned hydrogen.
