Common rail diesel discussion thread
It has been requested that I open a thread to discuss and share information about common rail diesel injection.
I am in the process of developing a controller to run solenoid controlled injectors, and plan to create a different power supply for piezoelectric injectors.
The difference there being that the solenoid injectors require high current and low voltage, although a moderate voltage (80 volts nominally) from a charged up capacitor is used to boost them during the opening phase to get a faster current rise. To keep them open requires only on the order of 6 volts.
Piezoelectric injectors on the other hand need a couple hundred volts to open, with high initial current and this voltage must be maintained to keep them open, at negligible current. Then in order to close them they require an inverse current as the piezoelectric element has internal capacitance that must be discharged.

Common rail is unique to most other injection control systems in that you have control over injection quantity and injection duration independently. Only other control system that offers this is hydraulically actuated unit injectors. Other solenoid controlled systems such as cam actuated unit injectors and injection pumps while allowing exact control of injection start and end do not have any way to control the rate of delivery  during the injection.

One advantage offered by direct electronic injection control that is not possible with rack controlled injection pumps is the ability to have multiple injection events during the combustion cycle. This feature is not unique to common rail but is also possible with some solenoid valve controlled unit injectors and some solenoid valve controlled injection pumps.
The primary advantage of this is being able to use pre-injection to heat up the air prior to starting the main combustion event, as this accelerates ignition of the fuel injected for the main combustion event and thus reduces diesel knock which is caused by a too abrupt ignition of the fuel (too much fuel is introduced before it is able to ignite in the chamber)

I will add more information to this post later. Feel free to ask any questions.

RE: Common rail diesel discussion thread
I wanna know something more about the EDC15/16 ecus from OM613/648. It seems that EIS, ESL, TCU and DAS and some ABS/ESP stuff is needed. The EIS will send a crypted can message to the ecu to start the engine. So we'll have to keep the EIS because it's to complicated to reengineer the crypted message. It seems there are two options to deal with the rest. First: Deleting all the DTCs in the ecu regarding ELS, DAS and TCU like wheelspeed and missing can bus devices and modify the ecu to start without them (gearlever in N or P for example). This seems to be the harder way. The easier solution might be to emulate all the can meassages the ecu wants do see via a can controller. Maybe something arduino based. There will of course have to be deleted some DTCs in the ecu because we don't want to run ELS, factory TCU, DAS and ESP. We must have a W210/211 car to reingeneer the can bus. To start the engine the gearleaver must be in N or P position. What other signals will the engine need to start? Maybe there can be found something in the WIS. Searching for some opinions or a little help from people who run these ecus in older cars.

RE: Common rail diesel discussion thread
As of me, i'm dealing with changing mechanichal properties of bosch CRD system to operate under higher pressure and higher flow and reliable for the tunning fans.
Electronically, as discussed a stand alone ECU without the vehicle electronics seem a lot viable. One feature must be present , the box must be switched in same socket as a EDC16 or have a kind of adapter. For the users without edc16 cars(loom) does not really matter which conector to work on.
Injection opening resolution is of atmost importance weather the coil or the driver , need to be in line with needs.
As there is no point using a diff nozzle if opening is not within 100's of milisecond. As example.

Just wondering, presumably on manual vehicles, the ECU doesn't look for some of these signals. Then is it easier to either start with an ECU from a manual car or perhaps the ECUs can be flipped from auto to manual?

The coding can be moved from one ECU to another with the STAR system. Ultimately it is just setting an clearing bits in the EEPROM, which can easily be copied.

There's no 613/648 manual car. Copying the eeprom is clear to me. But u will still need the matching key and eis for it.

I guess baldur is doing this just cause of that...
To run without CAN permissions , otherwise what sense does it make.
I belive TCU's , IMMO, etc, will be available as add on later if user wishes, if not please Baldur do it to run engine on minimal hardware...

Yes that's the plan. I will also have a complete wiring harness available for engine swaps if I manage to source all of the connectors.

There are quite big solenoid injectors too, I have new ones that give about 50% more then BMW550ds pizo injectors, orginal bosch, and they are resonantly fast at 8 event/ cykle according to bosch , now BMW can make 10 so a little bit slower there

RE: Common rail diesel discussion thread
I am making progress. First start up happened tonight. https://www.facebook.com/stalsmidjan.kna...056936849/
Timing is very late in that video so it smoked a lot and ran rough, and when I squeezed the accelerator pedal the smoke just changed colour instead of accelerating the engine, but I am satisfied with that result for the first start, it can only get better once I tune the timing and fuelling.

I do of course plan to make another version to drive piezo injectors once I have the controller for solenoid injectors in production.

I agree, I like quick response. That's my biggest complaint with modern cars, throttle response is non-existent, and the manufacturer made it that way intentionally.

This sounds super. I think the blacksmoke guys are on a standalone ECU now also. No idea but their tuner seems to post on here from time to time.

With this controller I plan to support nearly any engine that uses solenoid controlled high current injectors. Common rail, unit injectors (pumpe duse) and spill valve controlled injection pumps.

They may have, but I don't think they are. I think they are still using the EDC16 on the OM648, but they had struggles getting it to work properly although they got there eventually.

My current version is not for piezo injectors but solenoid injectors, I plan to make a variant of the same controller for piezo injectors later, they require a very different power supply as piezo injectors are voltage controlled but solenoid injectors are current controlled.
I remember the finns built a direct injection OM606 some years ago, but I think this is a lot of trouble when there are so many good common rail engines becoming available.

I have been planning to do a transplant with BMW edc15 from tu30 to a om613 because its much easier to program the ecu as standalone and they are quite similar in many ways.
Very interesting to follow the progress here , what will such product cost when its up and running ??

Thank you.
I do not know what the cost will be until I finish the final design and get it manufactured. I want to make it affordable so it will be an attractive option for engine swaps and not just for the most hardcore tuning applications.
I also want to make casual tuning of common rail diesels accessible. It is notoriously difficult to get good results with the Bosch ECUs which are not designed to be tuned by the end user. A simple to use solution that isn't 4000 euros is going to enable a lot more people to start tuning their common rail engines, and not constrained by what the factory ECU can do.

RE: Common rail diesel discussion thread
The prototype has been installed in a car. Here is an OM613 swapped Nissan Patrol. Tuning is not done yet but the engine runs and sounds very smooth and power is definitely better than the ZD30 engine it replaced.
https://www.facebook.com/stalsmidjan.kna...=3&theater
Using the stock auto transmission, accelerator pedal, instrument cluster and idle up switch. Everything works as if the car was stock, except it's got a better engine. None of that is easily done using a Mercedes ECU on a swap like this.

Yes, as the OM611 and OM612 use the same ECU board as the OM613 it will be a plug and play fit for those as well.
It will be able to handle any engine that has solenoid injectors, up to 8 cylinders, so OM646-OM648 and OM628 will also work but they will need a change of connector on their wiring harness. Same for earlier BMW M57 engines, Cummins, Toyota and even Volkswagen PD engines will work.
Once this platform is in production I plan to create another version for piezoelectric injectors which will cover all of the newest engines like OM642.

RE: Common rail diesel discussion thread
Ou yea thats my kind of response. Big Grin Well depends on what you want to achieve but sometimes you just can not yank bosch ems and throw it away. With descriptor files etc. its not bad to tune however this being mostly mercedes forum, tuning edc15c6 found on early cdis is major pain and you can forget about proper map scaling beyond 100mm3. On the other hand edc15c4 found on early m57 have descriptor files available and you can change whatever, even make it proper tuned for more than 100mm3, change throttle response and so on. So its either swapping bmw ecu on cdi or yours standalone system which would still be better as it is sufficiently dumb, bosch uses milion bites and constants around every parameter.

RE: Common rail diesel discussion thread
Baldur, I'm curious, are you planning on having any out-of-ordinary-readings cause a limp mode event? Or, if not limp mode, will out-of-ordinary-readings toy your ECU create an OBD type message, light a warning light or whatever?

Or is it simply a case of when something isn't running correctly, a failed MAF sensor or whatever, it's tracked down in the old fashioned way?

Thanks

Yes there will be a comprehensive set of self diagnostics on there including OBD messages.

Yes, as the OM611 and OM612 use the same ECU board as the OM613 it will be a plug and play fit for those as well.
It will be able to handle any engine that has solenoid injectors, up to 8 cylinders, so OM646-OM648 and OM628 will also work but they will need a change of connector on their wiring harness. Same for earlier BMW M57 engines, Cummins, Toyota and even Volkswagen PD engines will work.
Once this platform is in production I plan to create another version for piezoelectric injectors which will cover all of the newest engines like OM642.

You could easily fund development of this using kickstarter or Patreon or some such mechanism. I think there are several to choose from now.

It's not a problem. I have everything needed to develop it, only thing that is in short supply is time and much of my time is being eaten up by billed projects. If I apply the billed rate to the development hours on this project it's over $100k by now.
That being said, I am making progress. I am maybe 3/4 of the way through the design work on the production circuit board. I hope to get a prototype built of the production board in a few weeks time and then if I don't find any errors in that design I will pull the trigger on doing a manufacturing run. There are 4 cars driving on the initial prototype design and it works well although the firmware needs more development.

I know this is a whole other can of worms, but have you considered trying to tie in any emissions systems?  Some Bosch Denoxtronic pumps and spray controllers talk to ECU via CAN and somehow modify spray of NH3 in exhaust stream due to engine load, etc.  I've been looking into trying to retrofit a modified denox standalone system (or 2) from a Sprinter to try to modify exhaust gases.

Obviously, getting the main system ready for manufacture is first priority, just curious as to whether or not you've considered emissions control as a long term goal.

I currently have no plans for emission controls. I plan to address everything else and then maybe I will look at emission controls.
