Secrets to Bosch VE Injection Pump AFC Tuning Aneroid More Power, Less Fuel Wasted and Less Smoke

In this video I go thru a detailed look at how the Aneroid or Air Fuel Control works on a mechanical Injection pump. I discuss how it does what it does and how best to set it up to get it to perform for optimum power when you have much larger injectors. If you have stock injectors and only make 15psi of boost then your settings would be different. I also discuss why aftermarket fuel pins won't increase your power beyond what a ground stock pin can do and why in general I think they are a waste of money and a common problem I see many of them cause.

I wish you would do more on this topic like the power screw to get the max from the ve pump .

[@bcbloc02]

On a factory governor spring adjust the idle linkage and screw so that it is backed all the way down. Then turn the fuel screw in until it idles 800rpm. That is how I set them. If it tries to run away or wants to hang and not come back to idle quickly when you rev it up you may need to give it a turn or two on the idle screw and set it then. Next time I am working with a pump on the test stand I will get more into this.

[@davidmelcher3757]

I have 4BT VE pump. Upgraded fuel pin/gov spring and bigger injectors HX30W super turbo. I am dealing with cronic low torque on take off, super bad mileage and high EGT's. My Boost on cruising is 18-19 psi. I increased the diaphram spring tension to max but when I back off the smoke screw I lose even more low end torque. This motor is a dog until I get some boost and it never used to be that way. I have been adjusting all aspects including fuel limiter (backing off and increasing but only one full turn either way) I cant seem to get the proper tune. I had this pump upgraded as a set with the new injectors so I dont have the stock fuel pin to play with. sure could use some help dialing this in.

[@bcbloc02]

One big factor that will kill torque is improper timing. Have you checked your pump timing? Did you change it from where it was when it was running better? Could also be poor injectors. The other thing that stands out to me is cruising boost is really high. My cruising boost on level ground at 70mph is usually single digits. If your boost is that high no load how much drive pressure do you have? It would be good to know your setup when it ran batter and what you have changed since then.

[@infoanorexic]

I can overhaul/reseal one of those pumps, but knowing how to tweak them in for the best results is fuzzy knowledge for me. I'm thinking that I should make sure the injectors are working right first. Two were replaced after metal shavings from broken plunger springs prevented them from closing all the way, the others have just over 420,000 miles on them. I'd love to replace them all with upgrades, but .... $$$

[@bcbloc02]

Well now you know more how to do it. :-)

[@alexandreromao8410]

This might be a noob question but isnt changing to a bigger plunger just the same as increasing fuel supply on the max power fuel screw? For exemple, a 10mm with increased fuel screw would deliver the same fuel as 11mm with stock fuel screw no? Thanks

[@bcbloc02]

I assume you are talking about the plunger that controls the injection event itself. In the Cummins first gen world it is always a 12mm. There are currently no reliable larger options. As to the smaller applications for the ve pump like on Volkswagen then yes there are other sizers like 9 and 10mm. For a given control collar setting increasing the plunger size does increase fuel delivery. It isn’t linear though so a 9mm with maxed fuel screw may not make the fuel a 10mm can with the fuel screw backed off 5 turns which would usually be less than stock settings but stock settings can be anyplace depending on what the factory wanted.

What would cause injections not to have any fuel return on injections,Bosch ve pump rebuilt new injectors ,4 cylinder case IH engine

[@bcbloc02]

Well you should have very minimal fuel out the returns if the injectors are good like maybe a drip every few seconds when running. If you get nothing at all then it sounds like nothing is going into them. If they are new or worked on injectors they may have the pop pressure set too high or your injection pump maybe worn to the point it can't generate enough pressure to fire the injectors.

[@bcbloc02]

I don’t know what you mean by can’t get it set right. Assuming nobody screwed up the lever in the pump the fuel screw pushes against taking the top off or putting it on any adjustments that would need made can be performed on the truck. I can only guess that the throttle lever likely is not clocked correctly as missing it a spline one way or the other will throw off the fuel curve. If it wasn’t marked before when it was taken apart then getting it back right is pretty much a trial and error affair.

[@adolfomora7690]

Help me out here how do I adjust the cold start on these

[@bcbloc02]

Can you be more specific? I don’t understand what you want to do. These pumps start at full fuel delivery and maximum retarded timing so they normally start great in the cold. My truck starts down into the minus teens without even being plugged in with very minimal cranking.

[@stevenbean9706]

where did you get your masters in mechanical engineering ? now i know why its so easy to follow everything you are doing. what injectors and turbo are the most consistent and reliable for a pump set up like this ? i was thinking about doing head studs a turbo and injectors along with some port work cause i have access to a flow bench. what would benefit more on a diesel for me to work 11:53 on the exhaust or intake more ? im sure the bench would give me a lot of info but i kinda want to just chop chop and run it cause im planning on getting another engine to really build thank you for giving a little piece of insight

[@bcbloc02]

I got it from Speed Scientific which is now called the the Speed School of Engineering. It is part of the University of Louisville. At the time it was the only Accredited Masters level Engineering school in the US. I believe there is one other now. Injectors and turbo are always dependent on power goals. The head work again depends on the turbo you will use because how the drive pressure runs greatly effects how the engine flows and the head can be manipulated various ways dependeing on if you have negative or positive deltaP across the cylinders.

No when Industrial Injection got one and gave it to the Chinese to copy I quit. It took years to get the ones I had made in Germany sold and even some of them got killed for various reasons.

@@tomthompson7400 it sounds like your plunger and barrel is worn causing it to bypass too much fuel and fail to make enough pressure to pop the injectors. On either it gets over the cranking speed and it’s enough to make it fire as leakage is directly related to cranking speed.
