Default RE: Substitute for Ether

The reason for lower emisions is due almost entirely to the fact MORE air is available to burn the fuel not turbulance from the turbochager.
I'm glad you brought it up......now think about what you just said. MORE air is available to burn the fuel.........BUT......like I said, MOST of the time, after installing a power adder to a diesel, we do NOT need to add MORE fuel as well. Therefore, the turbo is atomizing the fuel better. In most cases, why doesn't the diesel burn all that "extra" fuel BEFORE adding the turbo? It wasn't atomized. I make another example.......we'll use gasoline in this example.

Let's say we have an engine that's fuel injected and we can program the computer(ECU) to mix ANY kind of fuel/air ratio we desire. Desired, in theory, is 14.7 to 1. Let's say we make it 5 to 1. That's 5 parts air to 1 fuel molecule. It most likely will not run cause it's too rich. Air is NEEDED to atomize the fuel at the correct mixture to cause it to fire. Basically(in rough terms) atomization IS air being added to a fuel. Diesels actually can run MUCH richer than, say, a gasoline/propane ICE(Internal Combustion Engine). Not to mention, any diesel that is set up correctly can run on just about anything that is combustible.

Ask ANYone who welds on cars/exhaust systems for a living........they'll tell you that they would rather weld around a FULL tank of gas than a half tank(ESPECIALLY nearly empty). Why? Cause the Air/fuel ratio in an empty tank of gas is "atomized" in FAVOR for combustion. All it needs is a spark, arc and/or compression. Now....ask the same people about welding around diesel tanks. They'll tell you, in general, they are not worried. For the fuel is not as "atomized" as easily as gasoline.

Turbulence from the turbo charger helps.....a lot.....but even more so is the fact that more air is induced to the fuel which in turn atomizes it better. You can throw a match on top of a bucket of gasoline and have a little fire. Now......throw that bucket in the air. What happens? Atomization! You won't be able to be within 20 feet of that fire otherwise you'll be burned but good! Try that with bucket of diesel. Won't happen.....if it does.....not near the effect. Cause it didn't have compression. It's like you've got to "force" the air atoms between the fuel atoms in a diesel.....because of it's "oily", sticky chemistry.

Again....not meant to insult anyone. But, atomization is(basically) the act of adding air to something. Making the air turbulent helps the process. So....using my example you quoted......without the turbo, NO more air would've been introduced to the mixture had it not been there. And if we make power(and lots of it) withOUT adding more fuel.....then how come we just boost our power levels? Cause the fuel was atomized better and made use of what was already there! It just wasn't mixing/atomizing on it's own good enough for complete burn. Basically, it was running rich.....but a diesel doesn't really "care" about rich and lean like a gasoline does. I mean, of course you can't run a diesel on air alone and you also can't pour liquid fuel down the intake and expect to run either. But, do you see a throttle plate that regulates air on a diesel? That's what I'm talking about......and here we are, by some miracle, operating a model diesel with a CARBURETOR!!! LOL! I think it's amazing! We are adjusting compression and mixing fuels to make the diesel run for us as we desire. It is because a diesel is so forgiving with air/fuel ratio that we CAN get it to run with a carb. Now......atomize it with an injector, preferably direct port......and NEVER worry about mixing fuel again! Just make sure it isn't froze up and can flow through the injector at a super fine mist.
