Yes, that's to do an injector flow test. This is a pulser mainly but can be easily adapted to do say a 50mS pulse test. Play with the circuit and you're welcome to post here...
Thanks, it's actually very easy. Get PC board seen here at RS, and populate the board with these parts. Go to Home Depot or online enclosures and purchase case or box. For probably $5 you could make this gadget. It's a lot more expensive to buy already made. Good luck and thanks.
Thanks... I'd love to hear more about water-ethanol injection and what you use it for. We're researching and testing ways or systems to save fuel, given that gasoline or petrol is likely to go up. The research takes time, but I'm open to ideas and input for the videos. Thanks again for posting.
I use a very similar circuit to inject water-ethanol into my air intake :D Love the way it performs. Thanks for sharing this video. You have amazing videos :)
You have many options. My Scan-1 (software only is cheaper) is one option and you can use it with any interface sold online. It is a good professional option. There are also the 170 dollar yellow-orange scanner from your local autoparts, which do the job fairly ok. There are dozens of options, but get the names and post here so I can help you out. Do it through a regular post, not private message so that everyone can benefit from our discussion. THanks again...
yes, it makes much sense, but here i see lot of adapters for different cars, I will start reading about the OBD-2 and learn, i used to read codes on my 1996 impala in a work shop but he didn't share any info with me, but i thought it was easy, get the code, analyze it in you mind, fix the problem, any way i will learn and get back to you, if you have or know any good books or videos please share.
Ok, I didn't see all your questions. Good, I see you downloaded and are trying it. Q1-The $149 and 599 is the same program. $599 using our tough built interface. You can get interface from 10 to $30 these days. Q2-The CD Rom has embedded video, both for diagnostics and as user's manual. Videos pop up right from the scanner screen. CONTINUED 1:
To test an injector to see that they are balanced there should be a certain injection time .How long will this device pulse the injector?Should there be an on/off switch or does it shut itself off after a certain time so you can accurately test each injector to see if they inject the same amount of fuel in a given time.
Why am I getting so smart this late in life? This is so easy for me to comprehend now as compared to years ago. If I had the internet as a kid i'd be rich. Looks like I won't need neuralink
Q5:when i chose Mazda & go to monitors tap then select status all the options are "Un supported" thanks .. i will keep exploring this program and give you my feed back. Thanks again.
Yes, that'll work. Some of these super cheap ones are bound to get stuck every once in a while, but who cares. Experiment with them, learn my software and then get a better one for 30 or 50 bucks. I'm trying to save you money, that's all. All my customers stay with me because I try to help them, not just sell stuff. I'll e-mail you with the link to my software on Amazon. Thank you...
FROM CONTINUED 1: Q3-OBD-2 has only one adapter, the OBD-2 standard connector, from 1996 to Present and all makes and models. Q4-It'll scan all US market brands or all OBD-2 compliant brands. You need to read more on OBD-2 before you buy anything, from either our publications or someone else. You need to learn OBD-2 top to bottom. first before getting involved in scanner diagnostics. Let me know if that makes sense...
in my testing the mosfet is always on independently of the. comp. output.... it works with a open drain output comparator instead... can make it work with a pc817 but ads more one ic and two resistors to the circuit....
Thanks man, the deal is im going to open a "limited budget" work shop, and i live dubai, to be honest... when it comes to car shops itis not that sophisticated, so only very rare shops beside the dealres use scan tools any way... i don't need a fancy tool like "Bosch KTS" which i have been told it is the best and gives you full access to all vehicles,also i didnt like the idea of the small code reader that cost 100$, what do u think about launch scanner & Autel MaxiDAS DS708... BTW. i googled...
Dear Mandy, Now i found ELM327 USB OBD2 CAN-BUS USB Auto Diagnostic Interface Scanner On ebay for 10$, i think the best way to learn is to buy it and check it out with your software, what do you think... mean while I will continue learning about OBD...thanks again & again
MaverickSaccomani GOOD JOB! Glad you had fun doing this gadget. Thanks for sharing... www.autodiagnosticsandpublishing.com/auto_repair_equipment_catalog.html
I googled " my scan" didn't find results, but some people told me that the computer based scan tools aren't that good, and it more expensive, but i disagree after i asked MR,Google, also i think it may be my best option cuz i need a tool that can scan many brands with full access, i cant afford a tool for every maker... I found the Autel MaxiDAS on eBay for 1000$, little bit out of my range but if it is worth it why not??
so... I downloaded your software and it looks very good... Q1. on the website their is an item for 599$ and other for 149$ to be honest i didn't know the difference between two. Q2. i got lost with all the options you have on your website which is good if you know exactly what you need but as a beginner i need an advice from a Pro, What to but from all, Q3. does it come with the adapters for different cars? Q4.can it scan porsche & Range Rover as it can scan VW & Land rover? Q5:when i chose...
No, forget $1000. You misunderstood me. It is called SCAN-1, (not my scan). I developed that scanner myself. You can purchase just the software for $149 & the interface from anybody for 10 to 30 dollars. Go to my site autodiagnosticsandpublishing (it's on my channel profile) and download my software for free. You can use it in DEMO, so try before you buy. Then get back to me here with questions. Let me know how it goes.
It seem the values for the resistors and cap on the 555 are to large. What freq ranger should I be seeing. According to my calculation even if I reduce the 1M pot down to 100 ohms you would still only get 2.5 pulses per second. Sorry I'm bad I read the cap at 47uF not nF, back to the breadboard.
Hi adpt I build this circuit exactly as you put it in the youtube video. Dispite the led flashing and the potentiometers werking I Cannot get a pulse signal from the injector output. I'm using a buz11 FET which should be a direct replacement for the IRF740. Do I need to connect the (555output pin 3) to the (393input + pin3) in order to get this thing to work? Cheers
Thomas Rouw Ok, first things first. Are you getting a pulse at Pin 3 of the 555 when you check with a scope. In my observation after dealing with a few 555 timer circuits, the quality of the wave is very important. So, check that and get back we me. PS. I've had cases whereby the waveform looks nice and square on the 555, but fails to do anything for whatever reason.
ADPTraining THis is the publication link just in case.... sites.fastspring.com/autodiagnosticsandpublishing/product/automotive_diagnostic_equipment ..... Here's the PDF CATALOG..... www.autodiagnosticsandpublishing.com/Automotive_Diagnostic_Repair_Book_Catalog.htm
I checked and am getting apulse from 3 but in you drawing this is not connected I tried running pin 3 of the 555 directly to the gate on the BUZ11 but that did not do anything. Anyway the led connected to the FET is blinking and I can alter the speed and duration of the blinking so the PWM part seems to be working however when I connect a load like in injector/bulb/relaiscoil the load is not actuated.
Ok, so the pulse part is working. THat's a start. Now, there are two possibilities here, the Pre amp part is not properly triggering the output driver or the driver transistor itself is not working properly. You need to check and see what happens when a load is administered. Can the driver provide the current? Is the Pre amp providing enough to driver the transistor? The second question is kind of senseless, but remember, I'm going from what I've seen in practice prototyping our stuff. I think the issue is in the driver stage. Maybe your substitute transistor is not the right one. Please, post back with your findings..... Mandy.
The two diodes are regular 1N2004 or any other general purpose diode. Yes we do have instructions on our book, Make Your Own Diagnostic Equipment. Here's also our advanced WOW Injector Pulser tool. www.autodiagnosticsandpublishing.com/Injector_Pulser_Tool.html
thanks man, im a follower of almost all your videos and i enjoyed and learned a lot, now i need to buy a cheap scan tool for my at home work shop, can i email you to get some help?
You can not use pin 3 output of LM555 because its a square wave output and it duty cycle was only about 50% to 40% duty cycle. This Fuel 'injector Pulser circuit need a variable square waveform out put for the fuel injector.. So, the design utilize the sawtooth output of pin 2 and pin6 ( Charging and discharging voltage of 47 nf.) LM393 will convert the sawtooth waveform into a variable square wave required by the fuel injector by varying voltage of 10k resistor reference voltage...
Hi friend. good morning. Could you give me a pulse generator diagram for common rail piezo electric and inductive coil injectors? thank you very much in advance and excellent channel !! I'm going to share it to the video
Copywritten? You mean the video itself and not the material contained within, correct? That circuitry can be found in many circuit design books and is included as a requirement in many EE and technical classes. 555 timer circuits are ubiquitous. In addition, that MOSFET is not amplyfying anything. It is being used as a switch to allow the twelve volts to pass to the injectors. Simplistically, the 555 is used to drive the gate of the MOSFET or base of a BJT in saturation. The load presented by the injectors regulates the amount of current they receive. All else aside, nice circuit, but the circuit itself is not yours. It is for public use without any restrictions. Nice try.

All
Please can you give us videos on how to test diesel electronic injectors by test light or volt meter
This schematic looks odd. Where is the out put pin 3#
ADPTraining
Does pin 3 connect to the LM393 along with pin 2,6 as it is in the diagram or should they be removed.
Poochie43124312 There is no ERROR. That's how it works for a 555 to output duty cycle control.
