The amount of diesel and smoke

[franco75]

speaking in condition of maximum load, the ratio AFR varies as a function of the rpm?

[munro]

the diesel does not ? as the petrol ? closely related to the ratio AFR as it deviates even slightly from the optimum, you immediately feel the difference in performance, or worse if you ? particolarmentemagri you can? break something especially in turbocharged engines....in the diesel AFR pu? go vary a lot with relationships magrissimissimi of 60:1, nothing happens...the AFR in a diesel is taken into account, it is more for a question of emissions,in fact if it drops to less than 14.5:1, it has a lot of smoke, but in contrast to the benza that if it falls below 12.5:1 AFR loses power the diesel in terms of AFR very fatty and smoky from a lot of power.....watch some tractor pulling, and you'll see you'll see that they raise to heaven the true and own pillars of smoke black as pitch, but the engine sings and pulls that ? a pleasure......

that 70 you find yourself also in the diagnosis?

No, in the diagnosis arrival only to 50mg.
For? I don't know how reliable that value as I am also an inconsistency remarkable:
- Air mass Measured: min 55 - max 542
- Mass Air Objective: min 289 - max 1201
So I guess that could have something with the mass air flow sensor and therefore the ecu limit? the diesel in the function of information it receives, to avoid smoking...
Anyone remember the values of a new mass air flow sensor? In memory of those reported as objective to me would seem to be correct, but I wait for confirmation...

that fiat 1.9 jtd are you referring to?

Fiat 1.9 JTD 8V 110CV with Bosch EDC15C7

[bart]

I have seen the fiat 1.9 jtd 8 valve with 90-95mm3 of diesel only the map and not to smoke so much....
I have also seen the fiat 16v mjt with 105mm3 without even a tear of smoke come out and powers between 200 and 220 hp.....
the fact I do not ? the maximum far is too far to not get fumosit? but where and how this iq is given.....if you mess up a mod with 50mm3 of diesel the car to smoke? a locomotive....

You can? get values for cos? high?
I thought that a motor with a completely original could not go beyond the 90...

[bart]

I agree as well, I inject 80-90 mm^3 at 4000 rpm for the way I like to drive a car in the diesel fuel does not make sense...

Can I kindly ask you, what does? What problem are creating? It gets too nasty? Smoke? Another?
Thanks!

[bart]

I agree with munro,is not how much you give but how we give.

This ? quite a dilemma...
I imagine about it there are many schools of thought! You how do you think is best? correct to intervene?

[munro]

with 542mg air and 50mg of diesel do you have an afr of 10.8!! your car dovebbe spew out black smoke worse than the titanic!! according to me c'? something that should not be....then who tells you that with an engine ori that you can't? to go beyond a certain iq?for what reason??
with regard to the maf values, goals are the norm of what a really good maf should give that a maf in good condizionedeve give between 289 and 1201 mg of air

More than the quantity? I think it is important to know what the stoichiometric ratio you can get off

You have grasped the zbc speech! In fact, the stoichiometric ratio is actually? ? the topic from which I wanted to start this discussion, only that I was afraid of making it too technical...
My idea would be to try to comply with a stoichiometric reasonable! Even why? I noticed that the fuel mixture ? rather lean, and then giving it gas, would only try to get as close to the pi? as possible to the ideal value! But without crossing...

[bart]

depends on the car

Have you tried to do the tests and calculations? Roughly what values did you come?
