Electronic timing

[jtanguay]

pretty smart idea to tap into the injector lines to find out when they break.  good luck getting it to work properly though  - its doable, but it wont be easy!

I don't need more than what I described... I just need to know what is the incidence of dual stage injector on a diesel engine and if it would be a good idea to monitor it.

Don't tell me I can't do it... because I am going to do it anyway... don't waste your time.  

Also... the link you sent me.. it is for gazoline engine. As there is no such words as lean, mixture, explosion in a diesel engine, I don't need to monitor the injection quantity on my IDI. It is going to be a tool to monitor timing ...that is all.

You`re misunderstanding or misrepresenting what I stated above.
WHAT Orbital does is irrelivant to the discussion here: the WAY they do it is. They tap and monitor pressure changes in 2stroke crank cases and use the data to time the injector activity with a higer degree of accuracy than can be had through purly mechanical means. Orbital doesn`t tap injector lines, like you intend to, but they DO look for pressure changes, like you`re proposing.
And for what it`s worth Mitsubishi uses the Orbital set-up under contract on some of its stationary diesel applications, so the technology is applicable to diesel as well as spark igintion engines.

Although, if he wanted to market his item, it would one cost too much, and two will cost him a hell of alot now to put each and every device together.  

Imagine this, you have this awesome sensor that tells you everything from belt tension, pump timming based on a fuel output analysis.  Then have your EGT temp running constant data to your mircoprocessor, then having another  running data from your turbo boost .  

At this point you essentially have a fuel management device.

Check the timming manually, make sure your pump is running to the proper setting, buy an EGT gauge as an anti cook turbo plan, and a boost gauge to test and tune you car.  

Another thing, motors are not and "ideal" environment for "sensative electronic items", hence paying a large amount of money for say a infared pickup, and receiver and then the cost of the controller itself to do this.

IMHO do what you like for you are human, I would love to see a fully cpable system that would indicate everything that could or will possibly go wrong with your engine.

[Hey]

1) I don't want to market this item.. I already have a pleasant job :wink:

2) It will cost me 10$ for the hall effect sensor and less than 20$ for a piezo.

3)the programmation can be made with a microchip like a PIC without problem (free samples..otherwise 10$)

If you want one... I will sell it 31$  :lol:  :lol: just kidding. It's gonna be a lot of fun and a dynamic timing setting is the best for 10mm+heads pump!

I don't think he's going to market this device, as it has already been done. Worth it? Your call... I think it can be done for less if you omit the snap-on sticker...

Checking the timing manually is exactly what we would like to get away from, it isn't accurate or repeatable from one pump to the next. The mechanical procedure is the best that VW/bosch could do in the 70's and 80's. The TDI could be, but is not, timed this way because there are now far more accurate and repeatable ways of doing it.

 I would disagree. I work in electronics as well. Machine tool and industrial controls for the most part. It isn't hard to make electronics survive in bad environments, I do it every day. Trying to do it on an automakers budget is always the problem. An extra nickel or two makes all the difference.

 You need to back up and re read the previous posts, what we are discussing here amounts to a diesel timing light, with no other function that I'm aware of. I don't suppose that you remember when we used to set gas engine ignition timing by breaker point opening, what an incredible boon it was to get the first timing light, you could actually set the timing with the engine running, with all the slop taken out and actual loads applied, it was guite a different picture from static timing. I think an affordable diesel version would be every bit as revolutionary.
