7,5 mm Element design for high performance engine
7,5 mm Element design for high performance engine
Hi,
You made one 603 pump to Estonia for om606 if you remember.
I have few problems with that...
First of all,pump was leaking oil and diesel but I fix those problems,no big deal.
But big knock at idle,black smoke at idle,if I start the car then the knock is really big and smoking like hell,not all cilinders start at time,idle is 1000rpm and bit rough.
At 220km/h I can switch 4 gear and boost is 2,3bar(never tryed 5 gear yet,its seems bit scary with that old SEC ),there is no lack of power but its still smoking badly... Last time speed was 250km/h and it has still loads of power....
Pump is 20 degrees right now and max EGT 760-780¨c
Any ideas?

Oh I would love to have some of your elements in my pump.. But for 250 HP/3 50nm would they be needed? Or would it be enough to pay you a visit sometime over winter? IF I get it running by that time.

Hi,
why 1000/min idle??
Next: 15 deg A TDC is about 24 deg before TDC physically start of injection.
Why not retarded to physically 15 deg before TDC or even later?
The shorter duration will allow it and it is less stress for the engine, also way more smoother.

(07-19-2012, 12:12 PM)dieselmeken I set the timing wing in the governor with a 15 degree offset, and if you do your math then you see that timing is 15 BTDC when running at load.

Quick question.
I have one of Goran's modified M pumps. Does one use Turbo 135 BAR injectors or Non-Turbo 115 BAR injectors ? Getting ready for some mechanical work. Thanks.
Hi,
I made better experience with 135 bar instead of 115 bar.
Less smoke at idle and under load and better mpg.
> 150 bar is harder to set up well balanced and to me it seems that there are no benefits.
240/ nozzles and timing 15 deg BTDC (checked dynamically).
Tom
500 BAR would be around 7,250 PSI. Is that possible .... ?
(07-20-2012, 09:38 AM)Turbo Would you get better atomisation by rising the pressure say 500bar by using Bosch P pump, and would it be possible with the nozzle?

So if I understand you correct in theory yes but in practical it get easy complicated. Do you think a p pump is something to try out? Plungers in pump 11mm for om606.962
MY concern is that it is hard to get a good burning in the beginning without getting it to sound like a stone crusher if your are going to put in a large amount of fuel. In common rail system I have understand it like you put in a little amount of fuel first to get the temperature up, then you can put in the main injection and the burn start at once with much more even combustion and the derivative of the pressure rise is much less, right?

Correct about the common rail, multiple injection provides a smooth pressure development in the cylinder.
We have the pre chambers to smooth the pressure rise and pre-spray nozzles like the old style 240/. On top you should retard timing with larger elements. My engine runs smoother than a stock timed untouched engine but way more power and no smoke.
I don't see the need of changing the pump type for even bigger elements.

(07-21-2012, 03:53 AM)Turbo what do you think about to change the pre chamber to some ceramic compound to make it more isolated to substantially lower the heat losses to the head?

Are the different supliers of elements really competitors?
This tread would not be the same without input from tomnik and the others that are into this.
There are more to elements than just putting in some bigger ones, and off you go. Sure, those videos with the "crazy finns" are amusing, but my car goes 2000 miles every year, and I am not looking for donuts, drag racing, lots of smoke, or 500 hp.
I am looking for better response, less consumption, more torque at the bottom, and a little more power, without having to change all other components in the drive train. I'd probably be happy with 200(+?) hp.
I will have some one redo my pump "some day", but at the present, there are too many other projects going. For now, I enjoy reading about it, and hopefully, I can find some one that gives me what I want.
It would be nice to know what the different suppliers want when they redo the pumps. What are your primary goal, what preferences are most important to you?
I dont see myself as a competitor with anyone, I just got some request on superpumps, and that what when it started for me. The topic is about how difficult it is to design, produce & test out a element for this kind of "outside the box" pumps.
Input is important from anyone, Tom has a great experience in this and I listen to him when it comes to technic, duration etc, from the beginning i was of another perception, thinking it was the amount of fuel and nothing else that matters. That was wrong, but the thing that is marketed on the internet sites is ccm, Myna goes 170cc, Herlevi 225cc etc, Why do your pumps "only" give 140ccm?
Anyway, now I take my serie 1 to a new level, This week a set of 4 plungers will bee grinded so that the helixangle goes up to 50degrees, that is nearly the same as the stock 6 mm boschplungers.
I have a small project that includes a VW 1,9TDI engine, that for the moment have a Valmet A-serie pump with 9,5mm plungers and a RSV governor with a really light weigt in, it goes really bad under 5000 rpm, but after that it starts to go OK, problem is that the pump is seizing one one cylinder.
http://www.youtube.com/watch?v=0s-EEeZnFes
Listen in the end when it seize.
Therefore I have a OM616pump that are going to get 7,5mm, 50 degree helix plunger in and we will se if it works out well.
I come back with some result later on /Göran
I think there is a great potential in the OM601/2/3 engines. Not only for huge output and lots of black smoke, but also for optimization and better driveability.
As far as I can understand, there is a lot to gain on just having the pump done, without the need of changing the turbo, installing intercooler, bigger exhaust, etc.
I am planning to keep my 1992 300 TD Turbo (om603 turbo) "for ever", and I hope to be able to have the pump redone "soon".
I don´t know how much this aboat "the fuel amount isn´t important" that is true? to some point yes, but as i have seen on my w123 with om606 and compound turbo, i ran 8mm approx 220cc mynä with aboat 90% rack travel and it gave aboat 450 hp and did not not respond to increased boost, then i gave it full rack travel and it now gives 550hp but stops responding to moore boost than 3,2 bar, so i measured the fuel pressure now and it dropped below 0,4 bar on full throttle. i am using a holley blue carburetor pump on original fuel lines with just a high flow filter. i will change fuel lines to 10mm now to see if it holds above 1 bar outherwise i need bigger transfer pump.
so what i say is that my engine is needing every drop of fuel to make that kind of power. doesnt give a hint of smoke over 2,5 bar. so i wounder if 140cc really is enough for high output above 600hp? if so am i seriousely having to small transfer pump if my 220cc IP doesn´t give more then 140cc now.
how much pressure to the IP does you GÖRAN think is good? mynä and jeemu told me 1bar atleast.
and is there any benyfits in having higher pressure like 5 bar or so? shouldn´t it giva a little faster injection due to the already high pressure of the fuel as it enters the element?

(08-07-2012, 05:34 PM)mantahead hi,no compression lowerd, is not the way to go! but for only dragstrip it would MAYBYE be better to lower compression to lower the "pump losses" or what the english word is. lowering compression is only for petrol engines who can "knock" pre ignite.
have you lowered your compression ratio, what is done to the engine and have you measured back pressure?

yes but you get used to it and then its boring, whant moore
can be a thing to do
you mean that you didn´t earn anything on it? what fuel pump and fuel lines do you have?
http://www.youtube.com/watch?v=6T6Y_75n0_A&feature=plcp and if you enter that chanel there is a few more, exhaust was leaking betwen the flange there so that why it so laggy
20btdc as mynä recommend
i know a few things to do to get more power but with stock parts i should get over 600hp on 4 bar boost! and a thing to think aboat is that it´s NEVER the boost pressure that brakes the head gasket.... its the power! imagine how much bigger the pressure in the cylinder is during combustion....
Min 1 bar 1,5 is to bee recomended when driving superpumps. Over 5 bar there is a risk that the rack will stick a bit.
You dont gain anything by raising the fuelpressure from 1,5-4 bar, its the flow that matters.
Some dynoresult from dieselmerc would bee nice to se.
I have done some testing today with my serie 2 element, 7,5mm 50 degree helix angle, The result was quite nice to see, for now I keep it for myself, Small filmclip will come soon.
I will have a testpilot that can take the OM606 engine up in a dyno so I have some result on my pumps.
The work proceed, I will try to refine my pumps some moore.
8mm is not going to happen from me, that I leave to the Fins. A bit too expensive according to my customers, dont know what Mynä charge for 8mm pumps €1500 or moore??
Mynä takes 1300+VAT Herlevi takes 1300+Vat for pumps with 8mm including new alda
Mynä promice 220cc, Herlevi promise 250CC

[/quote]
Mynä takes 1400eur and have been for a while, 1300eur is for 7mm.
Dieselmeken what do you think aboat the amount? I have never been able to measure what actual amount i am running but when everytime i have given it more amount of fuel it has given more power? Is it that i am getting seriousely less than expected or is it the big amount that is needed? And can you somehow calculate amount of fuel needed for a certain power? I mean for instant 140cc is max 600hp or so?

hi,
i was using 12mm fuel lines with twin filter housing from a renault truck.
inline pump i'm unsure what its off.
I was having problems with a modified restrictive standard exhaust manifold and only made 385bhp on dyno dynamics rolling road on om605 and hx35.
i just increased fuel pressure incase it was causing problems.
I would check with jeemu as he has alot of experience with compounds but your backpressure sounds high and your boost.
nice roundabout driving.

why is it so bad under 5000 and do you know cause why it to broke down?
I had 550hp with Myna 8mm and 170cc fueling at 1bar fuel pressure.
Had measured higher fuel pressure, no difference at results.
Fuel lines size is the key and other is original filter leg.
Seems at this summer not got new engine on the road.
Too bad, there is waiting new Herlevi 8mm with 260cc/6800rpm

First is 6 mm stock OM606
Second 7,5 serie 1
Third 7,5 serie 2
Speed is 1000 pump rpm.
All degree are pumpdegree, double up for engine degree.

__________________________
As you can see, serie 1 is quicker, at 72cc, it needs 11,5 degree to complete the injection, serie 2 needs 13 degrees for the same amount.
Here is also the answer to why the engine is so difficult to drive, it raise the fuel so fast on so little rack, that makes it sensitive on the throttle.
A small push on the throttle and BAM 100% moore fuel that stock.
Serie 1 is to prefere if you are satisfied with 350-400 bhp, if you need moore fuel, serie 2 or 8 mm is the answer BUT it needs longer time to inject = have to move injectiontime on engine.
Look at 6 mm @105cc, it need 19 degrees compared to no1 that goes on app 14 degrees
