Hello nice people,
I just watched a video that reminded me of the 1990’s and 1980’s, when I had a very smart older friend (and sometimes boss) who owned a small car electronics garage (pretty much like ETCG). He was an inventor and I was his electronics geek young friend. One of the electronic circuits I designed and built for him was something that he built fuel injector cleaning machines with. The machines were fancy looking with a few toggle switches and lights and hoses and he made a little fortune selling them to friends who run garages. The instrument was basically switching pulses with different patterns to injectors that had a cleaner chemical run through them at high pressure. They had 4, 6, and 8 options.This is a nice guy who looks like having a Turkish accent who makes good videos https://www.youtube.com/watch?v=8rk0tKtiVic who is using a much simpler process.
Is this procedure useful as a preventative measure? and is messing with the injectors (by taking them out and putting them back in the rail again) easy?
Is it worth the effort?
I wish that ETCG and the nice smart people in this forum have a say about this.Thank you
Vincenzo Masiello

My opinion about injector cleaning changes with the type of fuel injection being used. For Bosch CIS (widely used on VW, BMW, Mercedes, SAAB) during the mid 80’s and up until the mid 90’s (I think Mercedes used it the longest) injector cleansing was an activity with sound reasoning behind it. Bosch (or a company contracted by Bosch) even made an injector cleaning rig. These injectors “popped” or injected when a certain amount of pressure was reached. CIS injection systems were sensitive to having a good spray pattern, there was no electrical pulse needed to make the injector pop. If the injector popped too early or too late this was a problem. If an injector had a poor spray pattern this was a problem. If an injector could not hold pressure and leaked down this was also a problem.
I do not see these same issues with todays multi port, throttle body injection or direct injection. I will reserve any more comment on standard procedures for maintaining a direct injection system as they were just coming in as I was going out. I will say that many feel all the cleaning necessary is provided by additives in the fuel and fuel injector cleaning is not a maintenance item listed in the operations manual. This fact does not stop shops from selling injector cleanings though.
Thank you for teaching me something. I would still have an argument or two. First, I use SEAFOAM quite often, and it really makes the engine run smoother. I can feel a difference (or it’s probably just the psychological effect of loosing $7 every time I buy a can).
The other is that fuels and the materials they use to make injectors’ orifices/nozzles didn’t change between the 1980’s and now, nor did they way a combustion engine work. So, what makes you think that carbon and other deposits don’t gradually build up and partially clog the injectors.Are there any symptoms for partially clogged injectors or partially leaking fuel pressure regulators that don’t set codes? like performance/milage, etc.
vinny, I took the time to respond to you at length but the “system” said I took to much time and ate my post. Sorry.

Vincenzo Masiello[/quote]hi do you really believe the aerosol spray going to unclogged injectors?
i believe this one is the best way to clean injectors.
https://www.youtube.com/watch?v=oJf1d_6JEUUthank you much for the video. I wasn’t asking about the cleaning chemical but the setup. gas surely do. The setup in both is pretty primitive and dangerous. I’m thinking about switching all injectors on and off at a high frequency using relays and a microcontroller circuit. I have everything laying around in my place. I do electronic designs like that for a living and the material cost pennies
BTW, did the dude swallow his tongue in the video? this is much clearer https://www.youtube.com/watch?v=rUUgR94drxg
injectors are getting much cheaper bit like computers.
best to get professionals to clean them.
electronic designs cool job.
you should look into making and designing cheap (ems) engine management system .
atm is big rip off to buy one.
as i said before don’t waste your time & money on aerosol sprays.
kinda reminds me of the magic spray people use in soccer when player
gets hurt roflhaha
they still use that magical spray today.
I was thinking about brake cleaner or something stronger, but yet not bad to the injector.I still think that there should be some DYI something to do to them before thinking about replacing and $25 eah is not cheap if you think about replacing all.
I’ll google EMS to see if it’s practical for one person with limited resources and money to make something. Thanks for the tip.
