features CR injectors bosch

[munro]

Hello guys after a long search on the web I finally found a pdf that I think make? the happiness? for many who want to replace their injectors, common-rail, congnizione cause....
I would ask for?,especially tezzero and lumaracing that s? be two technicians diesel,but who's? something about me kindly a p? this pdf...the one that is not so much to me and clear the unit? to measure...I don't understand if you are in DC or in mm3....someone can? kindly enlighten me??
I am attaching the file for the pass, you can speak to me or msport...
Thanks to all of you.

In the pdf are indicated in the tables of calibration of the injectors bosch to do with test bench for pumps injection with common rail simulator.. test with injection pump "any"(I use that mercedes) are listed three tests : starter : 250 bar medium load and max load with the corresponding injection times (which are the same for all three tests) cubic cm of flow and ebb, that you should get with the associated tolerances..if you are not using a simulator bosch calibration values for the feedback change..I hope I was clear

hello tezzero..thanks for the clarification...I would like to ask you for? to confirm would be best if the unit? measurement in the pdf are in cubic centimeters and not in mm cubic...
and then in the light of all this, I would like to ask you what are the reference values of the maximum flow of fuel of the fuel injectors to be taken into consideration if we want to mount the "stuff more coarse" of the injectors, and the original date car always reading from the pdf????
the cio? where is the law which the maximum flow rate of fuel that an injector puts out??
Thanks in advance for your response....

hello munro..... I have not personally a tour, I've seen the pdf, but they are in close contact with a pompista.... however, the tour calibrations are expressed in cubic centimeters, CC, and the evidence, as he said tezzero doing so, but my pompista, does not try to 250 bar, but it only checks those bar starts the injector to open, then test at 1000 revolutions of the pump, (for those not in the know', CR pumps are reduced a half depending on the rpm of the engine.... that is, if the motor is 1000 rpm, the pump 500, if the motor is 4000 rpm, the pump, 2000 and so on) measure the DC to 1000 rpm, then repeated the test at 2000 rpm, and see if it reports with tables....

[tezzero]

the calibrations are in DC..The fuel flow rate in the table of calibration ? the actual maximum ? only a reference to test if the injector is working correctly..the injector.c.rail bosch differ in degree of splash number of holes and diameter of the same,we should have the detailed card of the nozzles and then compare them..but according to me this served as the bread for the mechanical injectors to increase the flow..with the mappings done well is increased to a great without the need for so much..

hi munro ,and can have the pw??
Thanks!

I've looked at the bosch table..I also use different methods the starting, for example, the text with 150 bar at 20 hz opening..if, instead, imposed the simulator automatically I f? do: 200 bar 20 hz start-up medium load 800 bar (60 hz up to 1000 bar 80 hz and ovviamneto I have the tables with the flow for most of the codes bosch delphi siemens denso etc etc..

ok tezzero...you want to tell me that from the tables you cannot tell if an injector from more diesel than another?
looking at the table, and taking into consideration e.g. an injector fiat 0 445 110 002 sivede that in the column where it says "de****y1" me between 8.2 and 9.2 cc of oil with 1350 bar press...
now if I I take a look at another injector fiat to es 0 445 110 119 I see that in the same column "de****ry1" me from 10-11,5 cc of diesel oil is always to 1350 bar pressure....according to my ingnoranza on the subject ? so???

[tezzero]

Do you not understand my speech or I have not explained well...the differences are there in the base with the holes and the size of the same and if we go on the technical and also the lift of the needle of the atomizer ? adjustable through shims..my account ? in the fact that by mapping the ecu correctly!! you get to increases without substantial ammattirsi in the search for an injector pi? performance unless you want to develop a car from the exaggerated performance..that's all

[munro]

thanks tezzero for the tuadisponibilit? to explain....but I would like to ask you if, for example, we take the bosch fiat 0 445 110 119 from the table, putting out 10-11,5 dc or 100-115mm3 to 1350 bar if I wanted to increase the iq to 140mm3 or 14cc without touching the injection time the press rail..what alternatives would I have??you could increase the lift of the needle to get more oil or and it is desirable to have an injector or nozzle directly big??
