Last week we tested the Scania to get more data about the engine.
We did not go to max RPM as the Dyno will not be able to handle this.
We did overload the system but the Dyno was able to hold the power but the loadcel was not able to read the massive torque.

 

Wow thats awesome I didn't you could get that kind of power from those. It's to bad they don't sell scania's over here. I've only seen one in person and I think it was lost because it had mexican plates. The sound of that v-8 it nice when you hear it going down the road.

 

Well I would not try to make this power with a standard engine as it will overspeed the turbocharger after about 2 seconds.
The latest Scania 16 litter makes 730Hp as standard.

 

Very nice, What did it make on the pull you made in the video ? A friend has a shop with a waterload Taylor Dyno that will bring anything to its knees. Best HP Ive seen on there was a street driven single turbo V8 Cat 1251hp...




We are working on a twin turbo 16L Volvo at work, Day Cab, Auto , Drag/Pull/Fun truck

 

On this dynorun we pull about 850Hp when the outer head lights go on, that’s the max the dyno can measure as the loadcel can only read 25.000Nm on the wheels. The electric breaks can handle a lot more for a short time until the disc heats up to far. We did run most of the testing on 2100 and 2200Rpm and only one on 2500Rpm to confirm that we have a flat torque line so we could calculate the max Hp.
We tested the injectors as well so we know exact where we inject and what quantity we inject so more or less we confirmed that we still have the same fuel efficiency if we go up the RPM range.

You can see what boost pressure we run by the head lights. The outer head lite go on by 1,5 Bar or 22 PSI boost and the inner turn on @ 2,5 Bar or 36 PSI
The smoke puffs are from a bug in new firmware we tested. The next morning we did the full load test, to bad we did not have a camera to show it all.
For those who know AFR or air fuel ratio we run between 18 and 16 on full load and close 13 during spool-up. 14.5 will be lambda 1 so we have a lot air left to burn.

We are still looking a company that can make a 12mm or 13mm plungers and increase the bore of the injector housing. We can get them from BOSCH ifew want to but it will take 2 years before we have them.

 

I know exactly what your talking about! Can't get anyone around hear to figure it out. nobody does any real tuning. Just flash, plug and play, or a chip! What your doing is What I want to learn to do!How long did it take for you to claibrate, find lambda and then blend?

 

What? Diesels tend to start to smoke between 20:1 and 18:1. Even if 14.4:1 is lambda 1 you are already starvin for air. don't forget that airflow and demand is almost 30% bigger than in a gas engine. you will run rich and your EGT's climb with that lean mixture...

Ask Banks, he will sell you enlarged, calibrated injectors from Bosch with a certificate and calibrated. Thats an expensive process done with extruding hone.

Heck, you can use common lamda sensors a few runs until they clogg, so it will be expensive -but serious testing.
There are plenty of real tuners. Not knowing does not mean they do not exist.
Ask Sepp Pappmahl, he is germanys oldest known serious diesel tuner- and he hates to work with ECU's. Ask ABT, Kw systems.
there is more than just pulling fuse F16 in Scania. Ask Wiechers, they participates in serious truck racing with great success and their race truck is one of the finest building arts over here.

Just have also a look at the danish dieselcenter in Padborg,DK- they will be happy to help you out.

 

@ Rustin. I’m working with diesel engines more than 21years engineering power plants and improving performance and fuel economy of a lot of engines.
We even made some modifications to a Cummins engine that became a CPL number.

Most of the stuff I do has to stay behind close doors so I’m very happy that I can support the truck pulling team and show the word what you can do with a diesel engine.

I don’t know if I’m doing tinge different compared to tuners? What I do is build a virtual engine by gathering all the information about the engine. The next step is to test individual components like injectors on flow rate and injection pressure and dead time of the electric operated valves. With this information we can correct the virtual engine parameters.
The only thing we don’t know will be the VE or volumetric efficiency of the engine and this we have to find out with engine testing as so many factors pay a part in this.
We data log all the runs and the ECU program makes it possible to simulate the run so we have good feedback on where we stand and how to improve things.

About lambda readings. Sorry I forgot to tell that we measure the real time values and not a RMS value so if I say we are jumping between 18 and 16 AFR than this will be the max also reading a 22 AFR as well. Have a look @ the picture.




About the lambda sensor. We use a normal LSU4.2 BOSCH sensor and we overcome the clogging problem by using a special welding bung. I know there are better sensors out there but the LSU4.2 will do and if one goes bad it’s only 65Euro to replace and so far we killed none even do we bow up 3 turbines sending a load of shrapnel down the exhaust.

I do not dislike conventional fuelpumps and injector and they still do great things as well and almost all the parts are out there to build a good working system.
I have moved on and like to use the electronic gadgets as they are easier to control.
Also the injection technology moved on and I have seen some values of the new race engines on some Paris Dakar trucks making me smile.

The funny thing is that the injectors we use on the Scania engine are considered to be old as well al do the engine is still in production, no new development will be done so no new bigger injectors down the normal channel.

@ Deezel how can I contact Banks or dieselcenter in Padborg,DK.

 

bankspower.com
The dieselcenter is located in the industrial truck center area in Padborg,it's one of the biggest truck centers in danmark. I will habe a look if I can get you some contact data.

There are several company working with extrude honing to enlarge injectors but tolerances are way to high, only Bosch offers calibrated injectors sad to say-but it is the truth.
You could also ask Dieselsend.de
Maybe they have a way to organize those injectors.

Did you already tried Monark in Hamburg, germany?As far as I know they do also custom work.

 

So far we only tried the BOSCH request department and came out with lead time of 2 years and a MOQ of 20 injectors.

So all information on where to get part will help a lot. Thanks Deezel.

I will also start looking for companies that build custom made hi pressure pumps as these part look a lot the same.
