Llss water injection May 17, 2021 11:22PM
I’m building a llss diesel tractor. For now I have an electric water
Injection setup. I was wondering if I could get a rough idea on what size
Jets to use. I have 6 port injection and 2 in the crossover pipe. Pump
Is 7-800psi. Thanks for any help.

Don’t port inject May 18, 2021 07:43PM
Don’t port inject your water. Keep it in the intake pipe but you’ll rob horsepower by port injecting it. That methodology is of the past.

So your saying don’t run water in the head. Just crossover pipe only?

You're not building a steam engine. In a diesel engine the lower the charge air temp the more HP. Indirect injection in the crossover pipe aka fumigation will do just that because of the latent heat of evaporation property of the water. It's good stuff.

Thanks for everybodys help. So to be clear what y’all are saying is to not run
Water through the head but in crossover pipe? Do people not run it in the head no
More? Whether it’s electric or gear driven?

Start with your desired flow rate of about 3oz/sec (1.4 gpm) and divide that by the number of nozzles 1.4/6=.23 gpm. Then put that in a nozzle flow calculator at 750 psi ( they have them online) and it will tell you that each nozzle needs to be 0.017" in diameter. If you use 5 they would be 0.019". Some guys burn more than 3oz per sec and some burn less. A rule of thumb is that it should be about 20% of what you burn for fuel. Hope this helps.

Start with 3 size #22 enderly nozzles. Space them in the turbo pipe evenly between the turbo and intake manifold. See what your exhaust temperature is and adjust nozzle size to get your desired temperature..

Not to sound like a smarta** but how would you take care of a hot cylinder if you don't have port injection? I'm sure you could cool all the cylinders off but it would seem to be better to only cool off the one cylinder that is hot.

If you have one cylinder that is hot enough to need more than the rest, something much bigger is wrong.

Your engine setup will have a little to do with how you proceed here. Turbo you are going to be using will also affect what your needs are. In order to be successful with a diesel in llss you need to kill off as much torque as you can. Steam makes torque.

So everybody is everybody saying you will get better hp
