Well we could marked the fuel system but you will need a big budged. Maybe in some years when commonrail become the standard for extreme diesel tuning we going to see some more of these conversion. For now most still use conventional injectors and the biggest ones they run where from penske racing produced in the old days for this engine.
Estimate is that one injector can handle 300 to 500Hp+ depending on the fuelpump and rail pressure.
The set-up on this engine is able to run up to 3200Rpm and with a reduction gear for the fuelpump you could run a lot more RPM if needed.
On themes on what the engine could handle, well my main concern are the head bolts as it only has 4 per cylinder and I think it will lift the cylinderhead. Second concern is the crank as we had it fail on the last engine.

It would be nice if someone had some real numbers on what this engine can do on a dyno so I have a sort of reference to what we can handle as we are going to dyno test it in week 2 of next year I hope.

 

Yesterday we tested the new build V12 Detroit Diesel commonrail engine on the dyno @ low load.
We run it up to 400Kw an than a hose from the charge air came of so we did not proceed making more Hp. All we wanted to do is break in the engine for more than 2 hours see if we had no leaks and cooling and oil pressure problems.

I must say the engine sound insane. Formula 1 diesel sound.



Next thing to do for the team is to install the engine in the truck and run some truck pulling event and slowly increase horsepower.
Last year ECU configuration worked good so I’m going to that to make progress and have a look what the log data from the ECU tells me.
Adding more fuel on this commonrail set-up is easy, just dial in more fuel pressure.

 

Nice!

 

Enjoy that’s if you like 2 stroke diesel engines.

 

We did have the madden run of Team FTF with V12 Detroit Diesel commonrail and they had the first full pull 2013.
I must say I’m very happy with the engine performance and it’s only running on 850 Bar fuel pressure and the system layout makes 1800 Bar possible so there is a lot more there but it will take some time to debug and cleanout the whole truck of problems and one of them is dirt in the fuel system.
The story behind dirt in the fuel system is simple, even the smallest contamination will block the pilot valve in these injectors and after some time it will clear all the contamination. Cleaning the system is not an option as we try this and it got a lot to do with the inner tube of the common fuelrail that’s is machined from billed steel.

Next step is to look @ the data from the runs and move from there but for now it looks like they will need bigger turbine houses as the boost pressure is getting a bit on hi site.

 

I can use some help on a 92 series V12 Detroit 2 stroke. It’s bending the con rods and I got the funny feeling they are very soft not able to handle the torque very well.

Any info on these connecting rods and a solution or part manufacture that build upgraded ones will help.

 

any news of your 2014 pulling season?

What ECU are you using or from what technologie have you made it? Are you using Piezo injectors?

 

We current run second position in the championship with the Scania V8 engine using pump injectors.

We build our own diesel ECU system that is modular. It a control box and injector drivers. Advantage is that we are able to place the injector driver close to the engine and place the control box in a place we can easy wire I more sensors.

We do not use piezo injectors, they are considered to be obsolete already slower than the last generation of solenoids that are far less sensitive to running hi load for a long time.

 

Very interesting. First you say you run pump injectors. DO you mean Unit Injectors?
ref: Unit injector - Wikipedia, the free encyclopedia
or you just mean pump injector in comparisson to your previous common rail setup.

What is the basis of your ECU. You built from scratch from micro controler or you use some existing development board like Arduino or similar?

Can you tell me what solenoid injectors you are using?

I'm looking for a common rail pump (like CP3), and injectors to run some diesel engines in standalone mode. Ideally would also find an affordable way to drive the injectors, would be nice to have a opensource Diesel ECU like megasquirt for gasoline engines.

 

Whoops sorry. The 2stroke is commonrail but this project have been cancelled after destroying 3 engines due to bending of the conn rods.

On our Scania V8 we run Unit Injectors or in short PDE or Pumpe Düse bit the same as Volvo and CAT are using.

What type of injectors are we using. Well depend on the engine, we run all kinds of injectors and valves on electronic controlled diesel engines including the Cummins/Scania PT systems like HPI for example. Last system we done is the Delphi F2D commonrail system with a 2 plunger hi pressure fuel pump for example.

We build a open diesel ECU called the 1280DI. DI stands for direct injection both petrol and diesel. It is open system and works more or less as a PLC or program logical controller so if you understand how to program a PLC it will not be hard to do all the programming your self. Most system we build have a base map or configuration that have everything in it to run the engine like injector and fuel pump control and if they want to run more pumps we ad them in to the software and allocate an output to drive the pump.

We also build injector or coil drivers for fuel systems and they are custom build for a type of injector.

Here you will find some information.

Diesel ECU system

This is our diesel test system and our customers use it for testing engines including R&D of new engines. This is my main source of income.

In general I need to know what you will be using on parts like injectors & pomp(s) and I will build a ECU system for it.
