Discussion: Injectors with more scope for the 1.9 jtd-m 16v

according to me what makes a truly innafidabile any engine more than the pme in the combustion chamber, which actually has its effects on the crank when very high, according to me, I repeat, are the egt derived from the times of 1200 us...all diesel fuel that burns outside of the barrel....even with 1800 bar rail pressure is not v? send a harlots the spray injection with the corresponding combustion process on which the engineers have spit blood to get it in a certain way... also with the times inj very long, you create a strong discrepancy between the press rail objective(cio? what should be)and press the rail and actual(cio? the one that actually the hpcr pump puts out) to the downside for the latter, also of 200 and more bars...said this to? I would like to say that inject massive amounts of oil with the relative quantity of air in the cylinder in a short time f? however, raising the pme...for? them should be taken, for example, by calculating how much the pme "digests" the 1.9 mjet twinturbo maybe even pumped a p? more to have a reference to know where we can? push...last but not least, I would like to note that if you mount the injectors are more big then you have to calculate if the factory ori c'? the f? feeding them properly otherwise ? all wasted effort....

You quoto munro in the first part, but when you refer to the delta 1.9 twinturbo not you can absolutely make a comparison..
Did you know that the pistons mounts? They are great pistons already? born to work on the edge of the 200-bar in the room of the series, have walls pi? thick and also the plug has a diameter of 30 mm, against 26 of the 1.9 120 to 140-150hp. Check the codes on catalogs, federal, and you will see for yourself. Once it is known that pi? or less the limit with the injectors of the series of the 1.9 150 hp and 120mm3 to 1730bar of rail, it can be deduced that an injector with a higher flow rate will be? always better, even if you do not decide to go to bring the cos? high.

however, I have seen mjet cone of the plug 26 and the walls less thick twinturbo put out between 220 and 250cv...
if you make two calculations, we are abundantly above 200 bars of the pme peak....
however, these unit? have percorennze chilomentriche worthy of note in relation to the cavalry who download....
then the speech that you do that the injector is large ? better when you want to give the diesel as god commands the strquoto in full, but I repeat, we need to see if the plant owers of the car, feed it properly, the new flow request from the injectors, the big...
I repeat that it is only by raising a p? most of the due to the timing in the map you have cali also notevolio between press rail objective and effective clear sign that with the injector open for longer than the pump does not send the right quantity? of diesel fuel to give the right pressure....that's why it's preferable to install a pump of low pressure and high pressure more big....

I agree that you can get to these cavalry, a p? less on the duration.. do Not confuse the pme with the pmax..
The pmax "you can't? calculate", is measured in the room with the false glow plugs, or even better with cell planted on the pistons.
I've worked with, providing them with the exhaust manifolds in stainless steel of our production, with a well-known company that prepares diesel competition for 24h, makes engines, the 2.4 jtdm 300 hp and yet, as pmax does not exceed 190 bar.

Has anyone fitted the injectors of the brera 2.4 210 hp?

You had the 308? Currently talking about the fiat group are almost the most? fast

to clarify: 156 2.4 jtd 136cv mounts geo fixed,
156 2.4 140 (mounting a VNT if I remember correctly)
156 2.4 150 GT2256V
156 2.4 175 GT2256V with trim more
159 2.0 170 GTB1549V
159 2.4 200 KKK
159 2.4 210 GTB2056V

closed OT

on the mjet 16v there should mount the injectors of both the delta twin turbo, both those of the 147 DC of 2.0.
Going in order of size from the pi? great to the pi? small.

*munro, playing with injections to the secondary you can make the last injection even more? 12? without too many problems.

From what I know and from the codes and the engine of the DC ? the same as the 150, so it has the same time inj then the same injectors

The 136 mounts it seems to me the td2306 that one of the few fixed geometry with the actuator vertical and is often used for processing on 1.9 since? bands management having the actuator in a closed loop,

Wrong, the injectors 150hp are the 243 or 391, while those of the 170 DC are the 341, watched the t-inj, those ducati's are much more? fast and the DC also fits the pump plus the CP1H R70. I have to check those of the delta that times have, the only problem ? that are piezoelettrci, I don't know if you can mount on the 140cv.
