Ignition Systems - How they Work | SCIENCE GARAGE 

I’d like to thank Science Garage for making me feel like I’m learning while procrastinating.

Bart .... There are a lot of secrets we are keeping from your wife. Is everything ok at your house?

I heard that lowkey part bout being screwed lol Update year 2020: Damn I didn't think this was huge 🤯 thanks guys😆

The only channel where talking about cars, in a kitchen, is acceptable. Always cooking up these great videos!

“And that part gets Screwed Must Be Nice”

This guy is underrated.. bring him back please

What happen to this show? Did they stop?

That dude didn’t look anything like Nolan 😐

Please do a up to speed on the Audi r8 or a science garage on ecu's

"That part has to be screwed, must be nice" had me dying! Lol

ABS - How it Works

I can't believe Bart stole that sparkplug.. Never meet your heroes, they say..

The best things happen after you hit the start button..

Hey random person scrolling down the comments.. Have a wonderful day :)

7:47 "let me put you on hold' *hangs up* classic pep boys

Donut is probably the only RU-vid channel that makes me enjoy sponsorship segments. Well done, Pep Boys...well done...

Don't tell Bart's wife how many scroll of town portals he wasted.

98 cents? that one didnt age well

I literally always look forward to these videos!

0:30-0:39 bart speaking only FACTS

"Threads get screw must be nice" hahahahajajajajajajajajaja

🙌 RAMCHARGERS 🙌

Thank god for this, the powers out at my school so we’re all just sitting around doing nothing

My favorite thing about spark plugs is how mind-blowingly easy it is to break car windows with the ceramic.

I’ll be honest 3 years later and this is the most effort I’ve ever seen put into a 13 min video. The buying of the spark plug was really well done. Didn’t even realize it was a skit Great job guys

Not all 4 cylinder engines have 4 plugs, take certain Ford 4 bangers. Even some V8s have 2 plugs per cylinder now (Hemis, 6.2 Ford Gas engine, etc.)

Thanks for another great episode of Science Garage, @Donut Media, I always eagerly anticipate these! I have a suggestion for your production team, in your past two videos the dynamic range of your audio tracks on the videos has been very high. In other words, the difference between the loudest sounds (like a shout) and the quietest sounds (like dialogue) is very high. This makes it difficult for the average viewer to hear regular dialogue at a normal audio volume, so the viewer turns up the volume to hear it, then when a sudden, short, loud sound occurs it is *very* loud for the viewer so they need to turn down the volume of their speakers, thus making it difficult to hear regular dialogue again, and so on. For action-packed videos, like a sci-fi space battle, viewers will likely enjoy having their speakers set to a high volume for the duration of the video, but for comedy, educational, and other dialogue-focused videos it can be uncomfortable to listen to and hard to understand. So, for the editors or whomever works on the digital assembly of your videos, I recommend they apply a "normalizer" and or "compressor" filter to the audio track, which makes the quiet sounds (dialogue) louder and the loud sounds (sound effects/explosions/shouting etc...) quieter. Most video production software comes with a simple audio track compressor filter that can be quickly and easily applied in post-production/editing that will make the audio of your videos more consistent. Just a suggestion from a frequent viewer, lover of Donut, and car fanatic, keep up the great work, guys! :D

I miss Bart

“Which gets screwed. Must be nice.” I was dead 😂😂😂

Bart was sad in this video, no screaming at least😢

REV UP YOUR ENGINES! It’s time for the Scotty Kilmer show... god I feel so ashamed to say that

"The bottom part of the spark plug is threaded, and that's the part that gets screwed. Must be nice." ~Bart 2018~

“...and that part gets screwed -must be nice” MY GUY WHEEEEZEEE

Where is Bart!!!

Hey man just wanted to say thanks , I’m taking Auto Tech in school and sometimes the chapter is so confusing and I can’t follow along or answer the questions but hearing u break it down makes it easier to understand

Glow plugs would be a good one.

I kinda miss the higher energy Bart, overdriven mic and all

"it gets screwed... must be nice!".... Best line of the video

He messed up the gap when he slammed it on the counter typical pep boys lol

I miss this guy

Must be nice 😥

Got to say, love this show! Got me hooked on the rest of Donut’s content, keep up the good work!

I'll admit, I'm not a huge car guy. But if you make a video that looks at any topic from a scientific point of view, that's going to make me a lot more interested in that topic. And this was really well done. Actually, what I've seen of this whole science garage playlist is pretty damn good so far. And I'll even admit that I enjoyed all of the non-science videos I've seen so far, too. So for a channel to take a topic I had little interest in and actually got me to enjoy that topic, even without throwing science into the mix. That says a LOT about the quality of the content you produce. In other words, you guys have just earned yourselves a sub. Cheers. And keep pumping out these great videos (preferably about sciencey stuff.) =P

just a nonsense comment, continue reading●_●

For such an electrifying subject, Bart’s mood is really puttin me to sleep..

Man what happened to this segment? This was one of my favourite segments of donut.

The threads were left handed on the illustrations

I typed this in hoping this guy would show up. Thank you sir for teaching!

3:11 Bart, you good man?

did he talk about gapping the plugs? sometimes plugs get banged around, and the ground strap may be closer or further away from the electrode, so you can use feeler guages to "spec" them so they are all the same gap distance which helps with fine tuning spark timing for high performance applications

He never put them on hold... just hung up

the bottom part is screwed, *must be nice* HAHAHAHAHAHHAHAHAHAHAHA these sublte quick jokes is what makes this guy so entertaining

I’ve been putting of getting a new ignition and my car shut off on my way to class this morning lol

I got a job as a parts advisor at nissan a couple months back. Your vids have really helped, thankyou!

Did you pay for that spark plug??

Ya know those random Donut holes (youtube rabbit holes where random stuff comes up).....There have been 4 cyl engines with dual plugs for years, early 80's Nissans for sure ('82 720 turd brown KingCab)

That distributor and wires are for an aircooled vw. Where’s my prize?

I wish I could gets parts by walking in and asking and walking out! This is a killer explanation

Changing spark plugs is easy? Where my ford 4.6 and 5.4 dudes at?

spark plug looks like a left hand thread.. AH HA!!! I'm smarter than Bart!! SUCK IT BART!!! (Miss ya though, come back!!)

Imagine that at the end of the whole series the build a race car with all the stuff they use or what the talk about Just a theory

Name: Bagus Kurniawan Kelas : XI TKR-1 Thank you for this video, this video helps make me more enthusiastic about learning

Bart is way too quiet nowadays

But why does my R1, with the supposedly long lasting iridium spark plugs, require me to change them every 12k miles? Is it the high, 13:1, compression ratio? The astronomical redline? Or just the overall high performance nature of the engine?

Bring back Bart.

"...let me put you on hold, bye." 😂😂 that is my phone etiquette from now on! F#@$ You customer! 😂😂

How they work - BOV and External Wastegates!

It was an Italian that made the first spar plug, he created a small cannon and by putting alcohol in it and making a spark made the cannon fire.

I was expecting a talk about the ignition that starts your car

Combustion can't happen without Spock! Live long and prosper!

I literally always look forward to these videos!

Miss these episodes wish they would of stayed

RAMCHARGERS!

Spelling mistake COMPRESSION RATIOS Nice video though 😁

The “hemi” has 2 spark plugs because they aren’t areal hemi any more and emissions 😂

It's incredible we didn't hear the word DOWNFORCE in this one!

😂 that part gets screwed "must be nice" LMFAO 🤣🤣🤣🎉

Portals - How they Work | SCIENCE GARAGE

I love how you were in and out with parts without telling them the size of your engine, how many doors, what color the floor mats are and all the other stupid questions you have to answer.

“That parts threaded, so it gets screwed. Must be nice.” Damn 😂 had to pause and die a sec

Can someone explain to me how spark plugs in small pull start engines get their spark? I know it has to do with the fly wheel but dont quite understand everything with the timing and stuff.

What happened to this guy? I loved his videos. Did he get fired?

This video sparked my day!...sorry couldn't help my self

Is it just me, or does his spirit pretty much non-existent in this video ?

I would like to see something from you Pls explayn every motor type (TDI, SDI, JTD, CDI, CDTI, SXE, TD,... all i could remember) pls make that video i awlais wonder what is what so i hoped that you can explayn because you awlais show "complicated" things on easy way to understand I'll hope you'll do that. Have fun making videos ✌✌

That explosion when his hand hits the table is always funny and random.

a few seconds in..... it can happen without sparkplugs..... and if it's a diesel, then that's how it's meant to be.....

Ok I'll get "UH" spark plug! I didn't know Nolan drinks dairy free milk...

We need a video on engine displacement, oversquare, undersquare, pros and cons of each type, boring and stroking an engine, etc. You could also put these along with other stuff on a video about engine blocks

Hey man, thanks for your videos. They're so well produced and easy to understand from the ground up. Which is great for me because guess who doesn't have a dad but still wants to be mechanically literate? Cheers

"94 cents a gallon with today's prizes"

Those must be special spark plug wires. When you came through your portal they were blue next thing I notice they are black.

@1:27 hey that's literally down the street from my house.

I knew there was collusion between donut media and Pep Boys and also knew that y'all together invented teleportation Gates that's it I'm blowing the whistle

MAKE A VIDEO ABOUT THE HONDA CR-X AND THE CR-Z!!!!!!!!!!

This is a weird mix... Is your target audience 8 year olds that somehow drive and understand sexual humor, preschool jokes, and engineering? That's like 3 people.

I'm in the middle of studying Aircraft Piston Engine Principles and this helped me get a grasp of how the ignition works. A lot of similarities to the automobiles too! Thanks a lot!

Ok, your fun to watch and learn from. A.

3:10 'that part gets screwed, must be nice lol.'

More explosions! We won't tell your wife Also, an ECU video would be cool.
