How Fuel Injectors Work

[@devonnewest7990]

Dude, you could REALLY be a teacher. Did anyone ever tell you that? You have an amazing gift of not just explaining things clearly (and calmly!!!) but you express yourself extremely well.

[@THXIIIRTEEN]

It’s called editing…

[@TheYesnoyesnoyesno]

Excellent - I love how you demystify these things without becoming either too theoretical or too specific. Thanks!

[@speedkar99]

That's my style

Thanks

This is a fantastic channel, I'm amazed how informative it is. Instant subscribe

[@pchris]

When I googled this exact question I was expecting someone to just show the fuel injector itself and vaguely talk about it and not show what I was interested in which is _where_ the fuel is injected into the engine. I am quite fortunate to have found such an in-depth video that showed me everything I wanted to know and even some that I didn't know I wanted to know like the inside of the injectors. This combined with some good humor made for a very good video. RIP your brother lol

[@daaknait]

Very interesting and a clear explanation. I'm glad I'm not the only one giving a second life to used underpants.

[@tgpnickandrew3094]

Maketsu haha. 2:29

[@speedkar99]

Haha, it's the best for dirty situations

[@v3xt0n]

I just cant believe the engineering behind this. It happens multiple times a second and it is still nearly perfectly controlled. Just amazing.

[@waynejackson1426]

Oğuzhan Yılmazer. That goes to show how complicated an engine is. That's the same speed the pistons are moving times two for any four stroke engine. Yet an engine can go for 400,000 miles and more before any major repairs. Amazing!

[@speedkar99]

Exactly what I'm thinking while I drive...

[@Primer9]

i trip out on how optimal engines are aswell

[@TheFreshsmith]

This is best youtube channel I've ever discovered, please continue to making these very clear and informative videos, your wittiness adds the cherry on the top

[@davidcardinal3654]

Currently becoming certified as a red seal ( KZbin) mechanic thanks to you!

[@speedkar99]

Glad to hear haha

[@joshoooway]

I really appreciate the hands on teardowns companied with the classroom style diagrams and lessons. Also, props to the color appropriate toothbrush selection based on subject content!

[@spiritbuu]

I like the raw old school style of explanation. Keep it up.

[@Gunbudder]

it finally makes sense... best explanation i've seen of how exactly the injector works. most of the other things i read just said "it atomizes the fuel" but i could never find exactly how the fuel is shut on and off. the solenoid with a fail-close port is a genius way of doing it

[@speedkar99]

Yes. It's hard to cut that injector apart with an angle grinder but worth seeing

[@Conservator.]

I’d like to see a photo of your brother smiling after he has brushed his teeth ;-) Tx for a excellent video!

[@speedkar99]

Eww He doesn't brush hence my supply

[@SE45CX]

[@hasbeengood]

One of the best layman's term description and tutorial I've seen. Well done.

[@speedkar99]

Thank you

[@garyg2]

10 thumbs up to this video. clear, to the point, with demonstrations and awesome diagrams i'm amazed how many "professional" youtubers post videos with only a shot of someone talking who can't clearly describe what they are talking about, sometimes no diagrams or piss poor diagrams usually on a whiteboard, and often no actual video of the parts they are talking about. at first my complaint was that you were going too fast, but in reality this was the perfect speed and i'd much rather have this video than 20-30 minute slow video

[@speedkar99]

Thanks for the feedback

[@akmahapatra4603]

Excellent demo with clear explanation for any layman to understaand.

[@FireguyNtx]

That was great, I been looking for a precise video of how they work, that's the one I needed. Thanks again for the good work.

Always great video coming from you sir, thank you very much. Don't know exactly how you do it but your video, compare to others I've watched so far is that you manage to keep the viewer "hooked" in the topic and never a sleep-inducing moment; and a little bit of humor gets thrown in for good measure.

[@speedkar99]

Thanks, that's my style, keeping simple and short

[@SangheiliSpecOp]

Believe it or not, It's stuff like this that really helps a car guy to understand their vehicle and what may possibly be going wrong or right in certain situations. If you know how something works down to the individual parts... You can formulate scenarios in yer head!

[@speedkar99]

That's very true, I'd rather understand something completely before diagnosing an issue

[@willowdero5269]

First time watching any of your videos and it will not be the last time. Thanks for the information and I like the high tech animations and explanation you used. Lol. Great to see someone using g real items and doing things old school. 👍

The fact that you rigged your own water pump to demonstrate how the injectors work is brilliance. Thank you.

1:38 Is there a reason why the wall is rough? I would assume the smoother is better perhaps is done in expensive car.

[@firstmaje2271]

You missed. The air is moving. I was wondering the wall is rough is because it cost too much or the resistance is negligible?

[@TheQuit21]

I liked the cross section of injector. Thank you ! Great video. that means at high pressure, injector will not open. about 100 it starts to sufficate and 130 psi it cannot open at all, yey.

I have a minor issue with a 2006 Toyota Solara Sle coupe....I recently added a fuel cleaner to the fuel...worked really good I might add,,,but the MPG gauge is stuck at 27 mpg....do you think junk got stuck in the fuel pump filter?

[@speedkar99]

The 3MZ isn't a very fuel efficient V6 espresso in the city.

[@hpt08]

Use a borescope to look at your cylinders via the spark plug holes. If it's really dirty, run some intake cleaner through it and try seafoam treatment too

How long do fuel injectors normally last? Life of the engine?

[@akupehsluarketatAR]

longer than the life of the engine. Injectors hardly broke down.

Yes Unless it's BMW lol

Or a freightliner m2 (garbage truck style)

Thanks for the video *******....... Cutting up the part to see how it works is Very Helpful. Fuel Injector coil windings "Electro -- MAGNET"....... PULLING up the return spring...... reminds me of how [I think] an auto trans Shift Solenoid works. Very good video.

[@speedkar99]

Glad you enjoyed it and learned something

[@Akira-nw4jl]

I had always been under the impressesion that the injector itself created pressure to spray the fuel , but apparently the injector basically opens and closes the orifice to allow the fuel to exit under the pressure delivered by the fuel pump. so actually the injectors don't have to work as hard as i had originally thought. thanks. great video.

[@hammadurrehman8991]

You need some recognition

[@scowley86]

My 88 Plymouth Voyager (Canadian Built!) is a throttle body injection. Does that mean that the injector is continuously flowing and that the computer only varies the amount of fuel being sprayed? I don't imagine it's being pulsed on and off when located in the TB.

[@speedkar99]

Yep Except it varies based on throttle input not valve input like port injection.
