NOS injection?

[R.E. Miller]

I keep seeing that guys are using nos injection on their diesels. How does this set-up work? What is the principle, cooling i. e. thru the intercooler, or making the fuel charge denser? I understand to a point how this works on gas engines but I don't know how this works on a diesel without having a Kenny Rogers roaster under your hood. Any ideas would be great, I hate being in the dark.
Thanks

NOS is nitrogen and oxygen being ingected into your engine,with more oxygen than you are able to put more fuel which equals more power,
at my job we have 2 big reaction furnaces that turn h2s into sulfer any way we have an oxygen plant where we basically reject nitrogen and what is left is 99%pure o2,well we inject the o2 along with our feed from our blowers into the reaction furnace,this concept is magic as for our plant,our combined feed stream is about 30% o2. making the total burn much more complete.
anyway NOS works the same consept,one thing to think about,the air going into our mighty cummins is 21%o2 and about78%nitrogen,. the thing I know for sure is n2 is an innert gas so n2 in is n2 out it only takes up space.
just think fellers your turbo efficiency is 21% as 78% of what it is making is of absolutly no value to the combustion process ,just a little fuel for thought #ad

I use the kit and it does have a cooling advantage. The super-cooled charge of nitrous is shoved in right at the intake plenum, just after the intercooler hose connects to it, making the air colder and more dense. Secondly, the nitrous is only air and since it is not a fuel like propane, it will not have the tendency to burn on its own and pre-ignite as the propane does. So, if there is not enough fuel or too much nitrous, all it'll do is take away some power with no bad side-effects.

Where did you get the kit for the mighty Cummins? I haven't found anywhere to get one and I'm seriously considering it.

I have a lot of experience with nitrous, but I don't understand where the extra fuel comes from on the diesel application. Does it just use a fogger type nozzle or just a straight line with an orifice to the intake? I have the NOS catalog and there is no mention of diesel kits.

Thanks for the help,

Thanks for the info guys, I just confuse the gas burners NOS applications with the diesel. I know in a gas engine if you do not have enough fuel and are running lean, you will melt your pistons if you don't adjust the NOS to compensate. Diesels run hotter egt's when more fuel is added, and this is where I get lost. Is this relationship just inverse for these two types of engines (i. e. lean+NOS=toast for gas/rich+NOS=toast for diesel)? Sorry for being hmmm, not smart here guys but I'm just trying to understand this stuff.
Thanks again

Where were you when I posted Oxygen Injection months ago. Think of the effect if you added a little O2 to our Cummins. I have to say a little because otherwise you will get all these responses about oxygen being DEVIL gas

Sorry, was out to lunch or plowing snow. I'll look your post up.

Nos has a diesel application system.
The extra fuel is already there. #ad

Its worth minimum of 50hp with a #42 jet and in the lower rpm's before boost as much as 120hp.

Yeah Hiperf360 knows alot about NOS. He knows it can blow head gaskets, and trash motors. LOL Sorry John Couldn't Resist #ad

So tell me guys. Does NOS actually affect EGT's at all? If so how good or bad on the average?

Bare with me I know nothing about NOS!

I have not had any problems with egts. My truck has tons of extra fuel (black smoke under throttle that can turn day into night), and the nitrous is just air being added to the fire. It really does work and uses a single orifice in the intake plenum. Call NOS tech or see www.summitracing.com for more details.

I think a guy would almost have to engineer a system that fit your truck, because the Summit/Jegs places have no idea of whats going on when you mention that "D" word.

So, lets go through it.

You need a bottle. Line to the intake plenum. some sort of electric solenoid for on/off purposes.

Thats about all I can think of. Never been a big NOS guru, so those of you with more knowlege might want to chime in with some practical insight.

I made mine from a old system I had in a tbi car.
You should use a nos solenoid($65) for reliability, and I have some extra bottles(100),activation switch and wiring bout 10 bucks,12 ft #3 braided line, and fittings from the bottle to solenoid and from there to the injection point. I went before the intercooler thinking I'd get a more complete mix through the intercooler. I also knew that that is the highest pressure ie heat so I figured it would help cool that down alot, it does.
You should see the looks on peoples faces when you tell them you have Nos on a diesel. #ad

 

[K_Arts]

DieselB58 - I don't completely understand your reply. Being that it sounds like to me NOS is just injecting air (and being that Nitrogen is extrememly cold) does this not raise or lower EGT's any? I hit 1300 degrees today with my DD2's and EZ. So if I can add extra power like NOS and not increase EGT's any... he11... this sounds like something that I want. Please guys. . give me any info that you can.

Yeah... so I admit it. After the DD2's. . I have become a BOMBaholic. LOL

[DieselB59]

The egts don't go up any when on the juice and I normally see 1500-1600 degrees on a full throttle quarter mile pass.

P. S. The head was off after 50K of this abuse to lower the compression a bit more and the pistons and bores still looked like new and the original honing marks were like they just were done at the machinist.
