How the Engine Lubrication System Works
HTML-код
- Опубликовано: 5 окт 2024
- Here's how the engine oil works to lubricate the moving parts in your engine.
Engine oil begins and ends its journey in the oil sump, at the bottom of the car's engine. An oil pump, driven by the crankshaft, sucks oil up through the pickup tube and pushes it through tiny machined galleries in the engine block to lubricate key components.
Oil pressure is created when oil flow is let through a tiny hole. The hole acts like a restriction, as the oil is let through at a high velocity, sufficiently coating and lubricating essential parts.
Oil then flows from the pump to the filter. The filter consists of an anti-drain back valve and a bypass valve. An OEM Toyota filter is taken apart and a paper filter is discovered to be the filter material.
Further down the line, the oil flows to the crank bearings, and up through the connecting rods to shoot oil at the piston walls and connecting rod bushings. The oil control ring on the piston are what's responsible for scraping excess oil off the cylinder walls so it doesn't get burned during combustion above the piston.
An oil galley feeds the head of the engine up near the top. It first leads off to lubricate the camshaft bearings (through the hollow camshaft), before splitting off into the variable valve timing solenoid and into the VVT-i gear.
A small channel leads off the head to pressurize the timing chain tensioner on the timing cover. A small squirt of oil also lubricates the timing chain itself.
Any remaining oil in the head, block, crank case or timing cover is left to drain down into the oil sump, where the oil is cycled back around into the lubrication system all over again.
The engine demonstrated in this video was from a 2001 Toyota Corolla with the 1ZZ-FE VVT-i engine.

You have sacrificed one of your engines to teach us how the oil lubrication system works we appreciate that. Thanks man very helpful show.
Hey I learned alot too!
@@speedkar99 how do you know when you need a new engine vs a rebuild? I had an oil leak and ended up driving my truck for 30 min without oil.
@@HighPriest1776 take the block and head to a machine shop so they can properly check for warping. If it did warp, sometimes they can machine the high spots down to get all mating surfaces completely flat and properly hone the cylinder walls out if it's not too bad.
When I was younger I was wrongly told oil just kinda got flung up everywhere it needed to go randomly from the engine moving - I really thought it dipped into the oil puddle at the bottom. Later I realised there were 'oil galleries' but I still thought they just sorta carried oil into different areas of the engine. I had no idea everything was this precise - it's amazing. And I didn't realise why oil pressure was needed but I can see now it's to make sure oil is forced through all those small channels. And that oil pump is like nothing I've ever seen too - I've made so many assumptions all these years, I just thought it had blades like a water pump or something. I'm astonished how much you can teach someone in 7 minutes.
So many processes to come from an iron or ally casting to an engine block.
The Engineers truly stand on the shoulders of many men who came before to design a good engine.
Well said
So much info in 8 minuets with no rambling or long intro
Thats my style
@@speedkar99 cool style
Praise this man for packing so much info and no fluff, stuttering, begging for likes/subscribes or god awful music. This is what a real RUclips creator looks like.
Thanks. Short and to the point is my style
Best video on the internet describing how oil flows throughout the engine!
Thanks - curious have you found any other videos like this for oil?
@@speedkar99 I've found super simple animations that don't explain the channels the oil goes through. great vid was literally the exact kind of video i was looking for
Moral of the story; your oil travels a great distance through many small holes and passages. Better keep that oil clean if you want your engine to last.
+Brian Day it sure does.
And stick with anything but murican engines, murican engineers don't know what they are doing when it comes to an engine
I like the “now I’m gonna cut this open to see what’s inside” lol, nice trade mark statement, and so useful!
Thanks. I've been using that line for all my recent videos and it works good 😃
I love a guy that knows what he is talking about and explains it quickly. I learned more about oiling in 7 minutes with this video than hours wasted with others.
Short and to the point is my style! Thanks
After trying to watch all the first few videos that are on the search result, finally found yours which is exactly what I was looking for. Thanks.
+InterlinkKnight glad you found it helpful
I'm an auto technician now, but why I totally enjoy your video daily is because of the cutting, we never had this experience during days of learning from the dealership as apprenticeship training program, I also totally love straight to the answer with your brothers toothbrush 😂
Thanks. You are right, mechanics don't get the opportunity to see inside these components, just replace them
@@speedkar99thanks man huge love ❤️🌹
i like how this oil pump is driven directly by crankshaft, not by chain. seems much more simple and reliable.
Yes that's good for engines that have the space for it.
I love your toothbrush lol... its like a pointer that professors use... subcribed and noti. squad
+AutOdometer thanks. Good old toothbrush is one tool for everything
I think Taryl Dactal is missing a tooth brush lol
This video is insane lol. Its fast and to the point! Literally every detail in the oils journey through the engine and then cutaways to chop up the pieces and go even deeper. I couldn't stop watching!! Great job and thank you!
Watched this after watching Thomas Schwenke's animated version of how engine lubrication works....very cool to see cut aways then the real thing in yours.
Thanks...I like to bring practical examples to explain. I find it's easier than animations sometimes.
This makes me wanna change my oil right now
You probably should
:)) I feel the same.
You forgot to mention the crosshatch on the cylinder walls. Those are very important in the lubrication system. One cannot just assume that the oil will lubricate the piston rings. Without those crosshatching, you'll burn the piston rings and walls really quick.
btw I like your videos a lot. I binge watch this shit. hells yeah brother, hells yeah.
+hostilityy thanks, I actually didn't think of the cross hatch
speedkar99 They're essentially part of the lubrication system because if they're too horizontal, they'll hold too much oil and the piston rings will just be floating on oil and never really grab the cylinder walls. if too vertical, the oil will just drain down and no lubrication and will fry the piston rings and cylinder walls. that is why they have to be "cross" hatch like 45 degree angle overlapping each other with specific groove depths.
your video is still perfectly fine without this detail because the average tuner or DIY guy doesn't know this stuff even exist. too technical lol
This is impressive. For so long, the small oil leak, which is supposedly common for my Subaru, has been blamed on a blown gasket. Not saying it's not to blame, but the fact you just revealed the bearing covers could wear allowing a leak and knocking, is new 2 me. 👍 Job bro!
You’re master, mr speedkar! I learn so much. And if I have a question about an engine, first I’ll RUclips you, a better explanation does not exist. It’s not only the explanation, but also the clear language you speak… not a hysterical typical American like scotty kilmer or chrisfix but just clear English. Thanks
Thanks. I'm Canadian
Comparing this video to all others on the same topic, they use diagrams and computer-generated animations with all colorful stuff, but in the end THAT’s what I was looking for ! ( just like the difference between color atlas of anatomy on a real cadaver, and other sorts of anatomy books 📚, there’s only so much you can deliver with diagrams .. the real machine dissection is a whole next level .. )
Rich in details and even the wear and tear marks, traces of damage and scratches, all give you a subliminal hint about the mechanics and you can always perceive the motion in your head , especially with old engines ..
You did a brilliant job here .. keep up with the good work 👍🏻👍🏻👍🏻
Thanks I'm glad this teardown helped. I have a similar perspective, animations are cool but seeing the actual thing shows you alot more!
speedkar99
You’re absolutely right !
Also, when you expose the internals of an old engine, and I see how clean some components still are, compared to the rest of the body, despite probably years of operation, I imagine all the sealing and filtration techniques for oil as it’s flowing along its journey through the engine..
you show all of that and much more without saying a word !
Your effort is highly appreciated man, and we’re waiting for more .. 👍🏻
This man is a Hero sacrificed his engine to teach us how lubrication system works under 10min 🙏🏽
Hands down this is the best video I have seen on engines. I am getting ready to do my oil pump and this answered questions I had. Thanks.
+Marco Rubio Thank you
I love this types of informative video because there's no BS, just straight to the point and easy to understand.
This is amazing how it all works considering how things are exploding and burning inside an engine. Thank you so much for putting this informational video out there.
It's so intricate!
@@speedkar99 Great jobs in Explained how the Oil lubricated throughout engine parts..... just for my Curiosity.... Thanks 👍👍
Best explanation I have seen on oil system including visuals. My oil system is completely clogged up. Don't think previous owner ever changed oil. Will have to change motor.
Wow.. that was a good explanation of how the oil flow runs. Thank you very much for this. Much appreciated.
It's so intricate eh
I have issues with low oil pressure on my Tahoe 2004. Am I forming myself how this lubrication system works. Resulting in everytime I start my other car I see in my mind how the oil reaches out to the camshaft rockers and I easily wait a few seconds before I start driving hehe… am more aware of how delegate this system is actually or actually more aware of how you can screw up your engine by not treating it with regular shifting of oil. 👍😎
Damn! Great job, and this is from a practicing mechanical engineer (who works with engines).
I'm a mechanical engineer too. Cheers
You are an excellent teacher. I’m binge watching this whole playlist. I feel like I can build a car after this lol
Thanks, glad you learn something from my videos.
This was awesome, so cool of you to put this together! I hope you are an instructor somewhere; you really know what you're talking about.
The oil functioning of an engine is quite complicated. This is well done, and reveals the system as good as possible.
Amazing video !! Not only you are very knowledgeable on the topics but also you explain it very clearly with great flow and no time wasted !! I didn’t need to fast forward anything.
From your ability to explain things so clearly I am going to guess and say you are CANADIAN !
Thank you so much! Your sacrificed engine & your detailed explanation helped me scratch my long, wondered & puzzled itch !!
Now I can’t rest peacefully 😇
You’re a hero to many wondering 💭 autominds
THIS IS AMAZINGLY GREAT VIDEO. Straight to the point explanations and very clear and great usage of engine parts. widened my knowledge much better. thnx.
Man this was fascinating! Ever since I started changing my own oil I was curious on how this all worked haha. Thanks for this speedkar! You've scratched a itch only a well greased man with a questionable toothbrush could reach!
+iPervy I'm glad you learned something from my video. My brothers toothbrush can sure make for a good backscratcher
Great editing. Concise and focused information. Thanks for the short video. More information in 7 minutes than others in 20 mins.
+O K thanks
Short and sweet is my style
this video has helped me to figure out i hav to replace the oil pump in my 2004 sonata hopefully ill b back on the roads with yall
great work man
Glad it helped
Excellent job explaining how the engine is lubricated. And thanks for sharing your knowledge and expertise! I learned a lot today.
You are welcome
You should make a video that shows all the spots where oil can leak from . I haven't been able to find one like that
Good idea...oil leaks everywhere!
The best illustration of high quality ever keeps up the good work SIR
Thanks! More to come.
Wow that is crazy complex. So provided your ambient temperatures allow in a warmer climate for example, thinner oil is definitely better than thicker oil for modern engines such as 10w-30 instead of 15w-40/20w-50 would be preferred. That way the oil flows a bit more freely through all those narrow holes & ports.
Yep and modern engines require even thinner oil because of tighter tolerances yet
20 years on major race car teams F1 Indy and off road I never had heard it put down like that awesome
Excellent, i have this exact motor with a low oil pressure problem (which otherwise runs fine). Help'ed me visualize exactly where all the oil galleries/etc are and whats connected too what. Pretty sure im dealing with some worn out bearings OR at most, a jammed/sloppy oil relief in the oil pump.
Might start with some thicker oil and see what it does too the pressure, then go down the hole of either pulling the pump, or the whole motor lol
Thank you for being here speedkar! I found you last month and I've loved all of your videos from then!
+Brubble Butt I'm glad you learned and enjoyed my videos.
Good clarity with dedicated cut sections when necessary for easy understanding with out making audience to go on imagination and assumptions, keep up the good work....
Thanks
i really love the way you explain things,i wish my instructor would have taught me in the same way like you do.
+cobra R thanks. I didn't think my style was that great, but I guess it appeals to some
You know I had the sound off and I wasn't aware of what channel I was watching... that being said, I spotted your BROTHER'S TOOTHBRUSH and "just like that", I was home :O) Thank your brother for me.
This channel is really amazing, demonstrations of everything car related!
Yep. I love seeing how cars work
@@speedkar99 love your content mate, seen a lot of videos, k24 engine, hyundai theta engine, ecoboost, and so many.
Keep it up bro 👍
I am pretty sure some JB Weld will work on that camshaft and oil pan when you put the engine back together. Might have to put on a second layer after the first one! Great video speedkar99!
This is the masterpiece of engine oil flow
Once again to the point and very precise.👍wow- so many places in an engine that can get build or built?up of crud and block oil flow. Always wondered how it lubricated everything.
Thanks. And yes there's alot of oil passages
Only just stumbled across your channel really like your style of explaining things and straight to the point 👍
That's my style. Check out my other videos
Immense details with top clarity great as always please keep these types of videos on ❤️❤️. I have a question please i didn't understand why the drain plug is a lil higher than sump floor??
I love your videos. Thank you everything you're doing for the community.
Great explanation. A lot more than an animation. If the oil pressure goes down then we can understand all the clearance of the cam,crank and connecting rad and the bearings are exceeds the limit. Isn't it?.
I wish I had teachers that had as much interest and insight as you do!
This perfectly shows 1ZZ-FE's piston oil pick up rings that were redesigned in 2003 due to the small holes getting clogged. Synthetic oil or frequent oil changes fights this.
This is real life learning. Pay for your engine.Thx
Worth it
Human mind is truly extraordinary
To create something functional like that
the best demonstration ever visually I seen a lots of them your is the best thank you very much for taking your time
Thanks and yes I'll have more to come
Nice , CLEAN AND THOROUGH, THANKS A LOT.
Your welcome
Many thanks, it's great watching this engine dissemble video, could you please make a video for engine assemble ?
Nice video. But can you do one about blood circulatory system?
_"Now I'm going to cut this open..."_
This was so informative..Auto shop 101 !!! Great presentation of how the combustion engine works!! 👍🏽👍🏽
Thanks although I'm no teacher 🤣
Just perfect video and explanation of oil pump and lubrication system. You are the best!
So I'm going to chop open this camshaft, filter, oil pan....LOL I think you really enjoy that part!
1:54 The oil Pikachu
Great video, thank you for your work!
Just got into cars. Amazing how intricate they are.
And the best way to learn is to tear it all apart
I've always wondered----does the 'clean & filtered' oil come out of the oil filter through the numerous small holes on the outer edge/diameter of the oil filter or does the 'clean & filtered' oil come out of the oil filter come out of the large center hole of the oil filter! Now I know! :) Thank u.
+asdflkjh thanks glad that clarified things and now you see how that filter works as a part of the engine.
Bravo man! wonderful video, I start to understand car mechanics much better with your videos. thanks for the resources that you dissect for us.
just a little question, I intend to repurpose an oil pump for some hydraulic project, do youhave an idea of how much pressure it can generate ?
Thanks
I'm glad it's helping you to understand!
I don't have specs for the oil pumps but you can try contacting some aftermarket manufacturer for that.
One of the most best videos here😮
finally a straightforward video with theory and practice found thank you man
Best video about engine lubrication on youtube! Thank you!
Glad you learned something
So thats how it works! Great explanation.
Thanks
homie you are mad. super informative. i need to watch this like 10 times. love your fun with an angle grinder
Thanks, and yep the grinder sure comes in handy
Literally the best explanation video I've ever watched! I came looking with dozens of questions and all of them got answered. Thanks!
Awesome!
Super interesting material. I never knew that oil pump is so sturdy. It must create tremendous flow inside of the engine. I wonder what's the difference between regular engines and super performance engines like in AMG series where oil's viscosity is similar to water.
Great video! Small suggestion: slow down a bit, it will make it easier to follow and absorb everything.
Thanks, I try to keep my videos short and to the point as to not bore the audience
@@speedkar99 short videos is good and for that you succeded very well. But as a non english native it get hard to follow, and I bet that those who ain't too knowledgeable in mechanics would have an hard time to follow too. 7 minutes or 10, still a short video.
Awesome video for clear understanding
Thanks
Best teaching videos from this guy, hands down.
Awesome video man, and 30K subscribers? You're growing now! Probably 100K by this time next year.
+Joe Milton eh, I don't think I've been growing that much, hoping for The best.
Thank you very much. I now learned how my Motorcycles Engine oil goes inside the engine. Wish you make video about motorcycle Engines
Hmm I'm not sure if 2 stroke engines have such a complex oil system. That would be quite interesting
@@speedkar99 pls make videos about Motorcycle too... I love how it's very detailed and entertaining to learn about an Engine. You should be a Automotive Teacher, my teacher is way behind of you interms of teaching... Hope explain how Motorcycle VTEC works on Honda Super Four and VFR
I love your brother's sock and your explanations. They're lit!
+lego technic ah yes the sock
The best tool for greasy situations
you sacrifice a engine to learn uste how engine lubrication work Thanks for the nice video very interesting.
You are welcome. It was worth the sacrifice
As you have pointed out, why is that they can't place the drain plug at the bottom most spot of the oil pan.
+Dominic Fong good question....
Maybe the manufacturers designed the plug like that intentionally, so that a minimal amount of sludge is left behind and over time the small amounts will build up and cause damage therefore you will purchase another car.
And If your car had lasted you 10,15 years tilll the engine stuffed then most likely you will purchase that brand again.
The manufacturers don't want your car to brake down to early but most of all they don't want your car to last for ages, only long enough for you to feel that it was a well built car and purchase their brand again.
Beautifully explained for a novice like me - well done
Thank you for cutting the stuff open.
Your welcome, check the rest of my videos for more
Best video description I've ever seen
Thanks for the detailed explanation...
Really concise and helpful. Thanks so much
Glad it was helpful!
Thanks for not being boring
Very informative, and educational video explaining how oil lubrication in an ice works.👍
Great video. I always learn something new from this guy.
+Labrador McGraw thanks. Glad you learned something new.
Thank You so much for that good explanation.
You are welcome
Fantastic video.
What do you think of using PEA additive in the oil ~200 miles before a change? Obviously not needed if regular oil changes are done with quality synthetics, but for used cars that don't have a service history or reliable prior owners?
Excellent video! Very clear, clear, and concise explanation.
Excellent video. If it were a tad bit slower it would be perfect. Talk a bit slower, hold the frame when you are showing a part longer so we can digest what you just said and what we are looking at. You say something and show something very interesting and as I am trying to have a look at it and understand it you are on to something else. Just a one second pause in places would allow our brains to keep up. I had to watch it twice and pause it... I guess that's a good way to get your views up. Lol. Very informative video. Thanks.
Thanks for the tip. I try to edit it concisely as to not bore my viewers.
This is literally perfect explanation!
Thanks. I'll make an updated one for the vq35de
bro u shud start a professional series or sumting ,very simple succint and clear ...very good.bro
+jason alcide thanks for the suggestion. What kind of series are you thinking?
there are many HOMEMADE mechanics ,, like me...all we are missing is confidence ..evryone will never be able to fix their own cars... meaning there will ALWAYS be work for professional mechanics ....BUT, we who are fascinated by the way our vehicles work , all we,ve been waiting for is a guy like you, to give us a way ...and THEREIN ..lies the market,, and hence the ...show.?.
great video , i thought that the oil pass through the filter before going up
It does
This is so aducative, good job bro.
