Cleaning the petrol injectors over the counter without ultrasound, possible?

[TTMsport]

As the title suggests, I ask if, according to your experiences ? can clean the fuel injectors of a fuel (Bosch Audi) over the counter without the aid of the equipment to the ultrasound. Then without gasoline additives or stuff like that. In the net you can find the video of cleaning the injectors at the counter facts with a given pressure (usually 3-4 bar) and liquid too diluted and with a device for opening and closing manually controlled during the cleaning process.
May work a thing of this kind of the actual inconvenience resulting from time lost, etc etc? I thank those who have actual experience to report about it.

I can bring a personal experience of mine, and this is from a video found on the web:
insert the injector by the part of the atomizer in a syringe (of correct size) from the side of the piston (previously removed)in such a way that the o-ring face seal, from the dive usually you insert the needle to connect the spout of a can of spray cleaning solvent suitable location, after that? you turn on the injector manually with a switch (I used a blinking arrows) and at the same time, actuate the spray in a way that the flow through the injector in the reverse direction.

Yes I've seen the video. But how many volts you have used to activate the injector?
The process has worked or ? a loss of time according to you?

The injectors traditional work at 12Volt

The injectors traditional work at 12Volt

small note scooby..you know better than me that the injectors work in duty cycle and then give it the 12v is to give him the 100% duty cycle....if you hold too long the voltage you can? say goodbye to the injector....

Certainly I agree, no one doubts what you said that is true. Of course not ? all you have the equipment (expensive) as necessary. Leaving aside the aspect of convenience or not, I ask (for those who want to have it at home) if, however, brings improvements before bringing the injectors from a pompistan (that, however, seems to me to ask for 25-30 euro per injector) that's all.

for what ? from my experience I can say that outside of the tour ultrasonic all the rest are just "paliativi" and pu? enforce said: "who the most? means spending less".... not s? if ? clear...

Are in agreement, but we have to distinguish the cleaning which is performed in the ultrasonic mode from the test which is carried out on the bench with the frequencies of the drive that reproduce the various engine rpm and burettes graduate is possible to highlight the differences in scope between the injectors.

the exact, in fact, I accenavo the before and after just because? with the tour you can? see before cleaning the injector, in which the conditions st? then once clean you can? see the result of all...

guys do not waste too much time with pseudo cleaning diy.....
the work of f? the tour ultrasonic not able to do any...
otherwise, what would have invented to do???
also then ? the only tool that allows you to see the "before and after".....

Definitely work on the tour ? the best, however, even the self-made something resolves, the initial request of the post was to know if there are alternative methods that work, and in my experience this is something I have solved.
It is always distinguish what type of engine you are working on and some times there are situations where the expense of a bench test is not worth for the value of the vehicle.
Having said this I conclude my intervention in this regard.

and that is exactly what you must do, with regard to the voltage, there are injectors that are also at 3v, in fact, on the banks of the ec test the switch to the exchange, to check this you just need a multimeter in ohms and see the resistance (and so also try the injector ) if it is around you 14-15 ohms and 12v if it is 5-6 ohms and 3v.
