New way of injecting

If someone really wants to take injector and combustion technology to the next level they need to work on a way to create better atomization with lower injection pressures.
 
That's easy, change the fuel......... That is if you don't mind crappy stuff @ 11.00 a gallon and really good stuff that will run in excess of 30 bucks a gallon.
 
What do you have against high pressure?, this is the way of the future.

I think the only way you could do it with low pressure would be with nozzles with many tiny holes, 20+. Then you would need super clean fuel filtered to under .005 micron.. there would be no room for error, anything in the fuel would trash your injector.

It would be more unreliable than the high pressure set ups.

There are a few chains in fuel. Get those chains down to a LOW level where they WANT more surface area and it'll happen. Of course you'll move more towards gasoline or worse.

Question... When you take a liquid and compress it at 250 bar or over 100,000 psi, what happens? Does it get really hot or does it get really cold?
How are we to get MORE surface area out of the fuel if we don't use more pressure?

What happens when you have a 150k injector set-up and there is a lot of entrained air in the fuel? What happens in the injector/cylinder when you run out of fuel or as you run out of fuel?

Less stress and wear on injectors, tips and everything else, plus less disastrous when an injector sticks open. What I was alluding to is why not work on injector/tip technology to try and get the desired atomization at the pressures used yesterday, ie around 5-15K psi? Think outside the box a little, maybe completely different style of tips, preheated fuel, ultrasonic nebulization, piezo technology using a 100 microbursts per combustion event, spray the fuel in a fan shape vs. 5-8 small jets, etc. etc.
 
So the idea for the multiple injection events on the high tech injectors is to slow the burn and even it out?

The Greendiesel guy didn't have much to say besides something would be happening in the US next year. I think the idea is ingenuous. The early low pressure injection event forms a donut then as that fuel starts to burn the high pressure event begins and sprays the fuel through it. Think flamethrower =)
Plus all that without the need for an IP.
 
I am running an 08 6.7 cummins which after much debate we have determined that there are in fact 5 injection events kinda the last 2 are more of a duration delay for the Paticulate Filter and reducing the NOX. One of the big advantages of the new XRT and Smarty S-06 is they advertise that these injections cucles are reduced or turned off which helps our fuel mileage a bit. our BOSCH fuel system is rated to 26000 if I remember corect our rail pessures are running around 22-23K. currently my truck is stock with less than 5K on it other than I unplugged the EGR valve on the dealers lot when I bought it. made a 330 mile round trip runnin 75-85 mostly intersate 70 and 270 hand calculated 20.8 MPG with 3.42 gears. Some of the guys are runnin up in the 650 to 700+ hp range with fairly straight forward mods. One guy at 791 with twins and XRT I believe. The limits of these engines is said currently to be around 1000hp and 2200 ftlbs of trq but that limit is only to be broken in a matter of time. These new engines are definatley the future as soon as the Emissions junk is gone. Dont get me wrong I love the sound of a true 12V but actually my 6.7 sounds more like a diesel than my 04 or 06 5.9 do
 
Nice post but ummm, I don't get it? What does that have to do with the new Green Injection system?
 
That stock the new systems with the high pressure are in fact more fuel efficient than the older lower pressure systems and mant of the truck have over 100K miles on them and have had no injector problems. My truck has 5K on it and you can run your hand up in the tail pipe and pull it out clean no soot at all. But as always some guys dont care a lot for the emissions system and have already disabled them and get even better fuel mileage with these systems. Maybe I misunderstood the thread but I thought they were discussing the new High pressure system and multiple injection cycles if not my bad, sorry
 
I agree, the new high pressure systems are the way to go. My exhaust is clean as well but it's at the cost of CRAPPY fuel mileage. Set the cruise @ 70 unloaded with my truck and you'll get maybe 13 on the hwy...maybe. The "Blue Tech" works as far as the clean part goes but for fuel mileage it sucks. It takes MORE energy to produce MORE fuel to make things "clean"...The battle is still not won with the current system. Moving MORE fuel will pollute the earth more than just letting the current system run a little dirty.


........So, in point, the Green system appears to be exactly what we have been looking for, a basic low pressure system with super high pressure tips. A system the avg wrench can work on. A system that won't cut body parts via cracked lines. A system that improves MPG. A system that could possibly improve HP as well. ...........and you can use it in other applications as well.
