Are there any learn engineering videos on Indonesian youtube channels? Thanks
Dude pls do make video on car cooling system working
Being ur subscriber I think I've rights to ask wht I need to learn so pls do working animation video of car cooling system
Please make clear and smooth voice background. Your voice was interupted. Thats why no proper understanding because of no proper voice delivery. Next time make it clear for good listening.
@@darshanvaibhav9098 Maybe if you were a patron you may have some kind of "right" to ask something, but in a global free online service, subscription just means you like the content dont be an a$$hole
I felt at 3:55 my soul was transcending. Like I had become a better version of myself after watching this video. Thank you for that Learn Engineering. I wouldn't be who I was after this 4 minutes of life changing experience.
great!!!
Lol
ikr? the Compression ratio resulting in better fuel economy thing was a light bulb moment for me. Everyone says diesel is better in fuel consumption but no one says why. this is just a great video. If you haven't check their how manual transmission works video. eye opener
that moment was totally hillarious :D:D:D:D:D
You put Vin Diesel in a petrol car to make it fast and furious.
This made me laugh out loud. Good job sir!
LMAO!!!
lol dude if u put diesel in a petrol car it won't start but if you would put petrol in a diesel car the engine will explode XD

*diesel in gasoline engine*
engine: "i sleep"
*gasoline in diesel engine*
engine: "real sh**!"
My question is can I put diesel in my coffee to make myself more efficient
+Steve Smith please try it nd let me know what happens
:P
Muhammad Hasham Ul Mulk okay muhammad, just tried it this morning and reporting in to let you know what happened.
At first it tasted a little weird going down, burned a little, similar to alcohol but more of a harsh chemical after taste. it wasn't more than a minute later that my heart began pumping rather fast and my head felt very hot, i was already sitting down but felt i needed to lay down. then i started shaking a bit feeling cold after about 3 minutes. at about 4 or 5 minutes i began convulsively vomiting and dry heaving which lasted about an hour. still feeling cold and nauseated i couldn't eat or drink for the rest of the day. my stomach felt as if it was inside out and i have a major headache since the vomiting. anyway I'm going to go to sleep soon and try it again tomorrow, assuming this was probably just a bad reaction because my body wast used to diesel yet.
+Steve Smith try mixing it with a little of Red bull to emphasise it as u may be used to red bull which ur body my appeal taking let me know what happened? 😉😂
+Steve Smith lmao
Try starter fluid.
Thank you so much, this is eye opening. I'm learning a lot from this channel, it deserves a five star rating.
Hi there! Nice job making these animations! There are also 2-stroke engines, which should get some attention too, because they also have some pros and cons, for example most of them have better acceleration.
I run the car maintenance TH-cam channel in Korea. I'm always learning such a great ideas on your channel. I hope we have a chance to be together. Thank you.

Clear and comprehensive!
Good job!
Point of clarification (correct me if I am wrong). Modern gasoline engines use a fuel injector along with the spark plug, as opposed to diesel engines that only need a fuel injector (and heater glow plugs for cold starts). And of course, carburetors were used before injectors to mix the fuel with incoming air, also requiring a spark plug.
Excellent video!!! thank you very much from Argentina!!
Sebastian Entenb You are welcome !
Awesome video! Thanks and keep up with the good work!
Thanks for the car engine videos. They're very helpful. :)
Petrol in a diesel will also kill the fuel pump as diesel is more oily in nature and lubricates the fuel pump
+IIGrayfoxII I've tank gasoline to my e36 diesel, it was 50% gasoline and 50% diesel, engine is running today now like new
+grodt88 Older diesles did not have such tolerances like todays diesels
We now have high pressure fuel rails, ect.
+IIGrayfoxII In modern VW & Audi diesel engines the fuel is compressed to something like 20000 bar. The fuel pump uses the the diesel fuel as a lubricant. If you put petrol into one of these engines the fuel pump will destroy itself because it has lost is lubrication.
+Zlatko Z are diesel and petrol made from the same source?
+MasterMorality Master Yes they are
The process of distilling crude oil you will get the following.
Asphalt>Fuel Oil>Lubrication Oils>Diesel>Kerosene>Petrol>Naptha>LPG
Man this just made my day to learn something new! Thank you!
Hi
Very informative. Thanks for sharing !
Best video I have seen comparing the two engines.
@1:43 both engines uses fuel injector not just diesel engines but gasoline engine uses spark plug while diesel uses glow plug
Jangan pakai seluar ketat AR!
GLOW PLUGS DO NOT HEAT THE AIR IN THE CYLINDER.. Glow plugs provide a direct ignition source for the atomized fuel
Glow plugs simple do not have the surface area required to heat the air and cannot heat the cylinder.. they literally ignite the fuel on contact with the incandescent surface temperature and allow reliable ignition until COMBUSTION heats the cylinder sufficiently to sustain ignition without the glow plug .
+teller of truth Every single engine equipped with a glow plug has the plugs bulb positioned so the fuel spray pattern impinges directly onto the hot surface... you won't find a single engine originally designed to use glow plugs without this distinguishing feature that is a direct result of how the system functions.
+teller of truth We are talking about glow ignition engines you fool! You will never find an Diesel type engine (SCCI) designed to use glow plugs that does not have the plug positioned in the pre-combustion chamber or directly in the injector spray pattern.
Please give an example of an engine that proves otherwise...
thank you for making it clear:)
Clear and simple, thank you.
Excellent explanation, well done :)
It would seem that this is the reverse,
C.R=Vtotal/Vclearance 2:50
Thank you for the explanations !
I was thinking that too
It *is* the reverse
Interesting as I drive VW TDI.
lovely and wonderful info. Thank you so much. looking forward to next video. :D
Great learning experience. Nice video
If you accidentally mix gasoline with Diesel or visa versa at the Pump, it's not such a big deal, you could just ride it out albeit with some spattering and splurting.
And in 4 min everything you need to know 👍
Very informative video. Thank you.
Thanks for the video!!
Thank you for the simple explanation :)
But why do i keep getting redirected here from the website ? or is it a problem with my computer ?
Muhammad Halawa Sorry for the technical error. We have rectified it. Thank you for notifying it :)
What about the emissions, why is diesel more dirty?
Indra Ida Bagus irregular combustion in the diesel engine is the culprit :)
Indra Ida Bagus It's the old time the emissions in diesel engine worse than in the petrol engine. Now, the emission in diesel engine is better than the old time and the petrol engine.
Ari Gunawan Yes, that's true. Diesel engines have made good advancement in recent years due to the technologies like turbocharging, direct injection and EGR.
Learn Engineering You indicate that irregular combustion is causing the particulate matter. I had understood, that a higher rate of combustion in diesels is achieved overall - resulting in a higher Carbon Dioxide to Carbon Monoxide ratio. The more fully oxidized carbon means more power and less poisonous carbon monoxide. I assume this is the efficiency of compression. While some is not completely oxidized - creating soot, most is completely oxidized - creating more carbon-dioxide than carbon-monoxide. Is this correct? Although, you can't see the pollution in the gasoline engine, it is the carbon monoxide which is the danger. I think the carbon-monoxide problem is more of a pollution hazard than the particulate.
While you can't mention everything in a video, one aspect of diesel is safety. I belong to an association that rebuilds and maintains antique railway equipment. Diesel is not prone to detonating or burning outside of its intended combustion chambers due to its flash points while gasoline is very dangerous in creating fires and explosions outside of the combustion chambers. When working with large volumes of the materials in industrial situations, it makes a difference. We have had fire problems with the gasoline pony motor that starts the diesel motor in the railway crane, but never in the diesel motors. At the beginning of Standard Oil, the chemists considered there was no safe consumer use for products in the gasoline volatility range.
***** Tank you for this great piece of information !
Tgus channel is gold. It explains things so well
Thanks for the explanation.
+Learn Engineering I have a question. with which program you create this animation
Blender, I think
Gasoline engine is more powerfull, but diesel engine is strongest then gasoline, i have diesel Mercedes car from 1980, he has more than one million km (600k miles) and it works perfectly.
Very informative thank you
Best explanation on this topic I found.
Diesel in a gasoline engine: **Ignition sound** **silence**
Gasoline in diesel engine: **Bang** *thunk** **thunk** *thunk** *KABOOM*
Modern Gasoline engine also contains injector :-)
Gromosław Śmiały or carburetor
I wrote: modern engine, in other words under production :-)
Gromosław Śmiały oh ok i didnt see that, thanks
pretty much every gasoline powered car since the late 80's has used fuel injectors.
Yes, but they still have a spark plug to ignite the fuel. Diesel engines don't.
Thanks for explaination :D Great video, simple and easy to understand. Exactly what I was looking for :) Stamble across it accidentally and now I'm one answer closer to satisfing my curiosity :P
Thanks Great Video Excellent Camera And Lighting Decorations Very Beautiful
so the intake valve of diesel engine is only for air right?
+BRITANTYO WICAKSONO (FREEMASTER) Yes, how the video shows, the diesel engine has fuel injectors where the gasoline engine has spark plugs, so the diesel engine intake valves are just for the air
+Alessio Di Blasi i wonder how that hot air for diesel was heated
CLARIAN KEN
If I remember well: You don't need that, air, since it's a gas, get warmer and warmer the more it is compressed
@@clarianken4223 One reason why gas heats when it is compressed, is the friction of the piston moving along the cylinder walls. Another more significant reason why it heats when compressed, is the work done on the gas, increasing its pressure and decreasing its volume, goes into its internal energy, which therefore manifests as a rise in temperature.
I always thought that gasoline is way superior to diesel in any sense up till the point where he says that diesel is more efficient due to the better compression. Gasoline is smooth combustion and diesel is uncontrollable explosion, and I always thought bus companies and heavy machinery used it because of low cost and they don't care about noise, and now I am wrong. Nice explantion
They also use diesel engines because they create more torque at much lower rpms, which saves on fuel and reduces wear and tear on the machinery.

Diesel engines are used in heavy machinery and large vehicles like buses and semis because they create more torque at much lower rpms to lift and haul heavy things. This not only reduces wear and tear on the engine and other moving parts, but saves fuel too.
+Jane Gerrard Cost is the main driver in Europe. Plus Diesel engines over here in the states have a bad rap for being noisy and stinky. I assure you, once fuel prices in the states start approaching what they are in Europe, US will adopt more diesels. UNLESS, HCCI technology can be perfected. It's the best of both worlds.
Thank you for valuable information
Thank you soooo much for such clear explanation and wish you all the best and expand more
Petrol (gasoline) engines are a thing of the past here in the UK, Diesel engines have rapidly taken over the market within the past 10-15 years and are seen as ultra modern, economical, low emission engines. America need to go the same way and move with the times!
+jblsound13 Very well said and this American intends to. I want to get an older Volkswagen Jetta so I can make my own biodiesel fuel for it.
+Jemalacane0 If you do that, make sure to change anything in your fuel system that's made out of rubber to biodiesel-compatible rubber or to braided stainless steel - this mainly means the fuel hoses. Biodiesel has very strong solvent action, so it can eat the lining off fuel hoses and wash rubber into your fuel injectors. Also be sure to replace your fuel filter after each tank for the first three or four, because all the crap in your tank and lines will wind up in your filter.
Also...biodiesel makes THE BEST parts cleaner in the world because it is such a good solvent.
jblsound13 I was a fan of diesel when only I and few others had it (I had diesels since the 80s). Now I hate the loud noise the traffic makes :) What makes matters worse it's that nowadays they're all direct-injections, way noisier than the indirect injections used in the 80s.
It's because in the UK, all you have is tiny bean shaped cars that suck and are slow and ugly.
Russell Rai are you for real?? My little old 1.7cdti would leave most of your old fuel guzzling monsters trailing long behind you idiot, my 3.0TDi Audi Q7 would simply put you to shame!
Thanks a lot mate for such a simple explanation...
Very good and simple explanation gracias
-Do you prefer diesel or gaz ?
Mazda : Yes
petrol engines still have fuel injectors... along side a spark plug. diesels have injectors and glow plugs
but the glow plugs are not there to ignite a fuel-air-mixture, in contrast to the purpose of a spark plug.
Glow plugs are used to help diesels start in cold weather. The high flash point makes them vulnerable in cold temperatures.
The glow plugs do in fact ignite the air/fuel mixture... the difference is they are only used on starting... not running.
Of course glow plugs are redundant.. most Diesel engines don't have glow plugs
@@doktorbimmer again, you? Most diesels do have glow plugs xD. Omg get your facts straight
@Trex *FALSE, most Diesel engine designs DO NOT have glow plugs, Glow plugs are typically found in Automotive and Light Duty and some Medium Duty engines... Glow Plug systems are rare on Heavy Duty type engines.*
I needed this in my life
The best video on the hole internet for this explanation!!!
You could use rail injection on petrol engine for better information, and for the users to understand, looks like you draw the old non injector petrol engine ;)
btw usefull info.
Good video but both vehicles have an injector.
Kelly Burgess Yes they do but diesel doesn't have spark plugs. I'm guessing the injectors go where the spark plugs normally go in a petrol engine. I think that's what he was trying to get to.
we talk about engine in general
I think he's talking about instead of a spark plug there is a fuel injector in the same location
yes modern petrol engines are fuel injected which makes them more efficient by causing fuel to burn completely
your these kinds of informative videos develop our situational awareness in which live world with some equipment that makes our life easier and it creates a new route to be productive in our business and life. THANKS.....
a million thanks 'Learn Engineering'
I hear Volkswagen knows a lot about diesel engines and making them clean, is this true?
***** It was a sarcastic joke. :P
+Maestro_T LOL
+Maestro_T Yes they do. They actually make very good diesels. The problem they had is meeting the government standards which they did do.
VW also tried to meet the standards of their customers who expected a certain amount of power and mileage. They also met those.
VW was off my a very small amount from the government numbers which themselves are a very small number. Did they cheat to make it seem they hit the numbers? Maybe, but then people don't want to pay the cost of the car if they did it completely above board as the government says.
Tigerfire75 Thanks, Buzz Killington. :P

Thx for the videos, very simple :)
Im a little bit confused now, you say that a diesel uses a fuel injector instead of a spark plug... Does it not use a glow plug AND a fuel injector? The Glow plug taking place of a spark plug?
Having a fuel injector in the combustion chamber is known as common rail/direct injection, you say gasoline engines MUST be premixed with air, yet it has been practice with the most efficient of gasoline 4 stroke engines over the last 20 years, and is more and more common today, to use common rail/direct injection fuel injection (with an injector and a spark plug in the combustion chamber just like the diesel) in gasoline engines. Sounds like some severely wrong information being given here.
Craig Kulig Even in 'direct injection' engines, the combustion does not happen due to the injection. It is just another method of making fuel-air mixture. To initiate the combustion the spark plug should be activated.
No bro the glow plugs on a diesel are used in the initial starting of an IDI or indirect ignition diesel engine ie when its cold, think of the glow plug as like a miniature coil on your electric stove. So the glow plugs doesn't really ignite the fuel in the diesel like a spark plug in a gas. The glow plug heats up the cold cylinder to get the air hot in the diesel,because of its high flash point. Gas and air mix on intake stroke, diesel and air mix on Powerstroke.
Craig Kulig Glow plugs are a common form of an intake air preheat on indirect injection diesels, they only function when the intake/charge air or engine temperature is below a certain point to aid in combustion. Air heats up as it compresses, and the astronomical cylinder pressures created by the 16:1 and higher compression ratios found in diesel engines super heat the air uniformly throughout the combustion chamber, which is necessary to ignite the diesel, where as a spark plug is used in a gasoline engine because of the atomized fuel's higher volatility. Don't confuse common rail and direct injection as being the same thing, either. Common rail fuel systems are a relatively new technology utilizing electronic solenoid unit injectors for both direct and indirect injection engines. Direct injection has been around almost as long as diesel engines themselves. Unlike gasoline engines equipped with direct injection, diesel engines inject fuel just before top dead center on the compression stroke, that's why it's not uncommon to see dynamic injection pressures up to 6000 psi on pre-21st century engines, and over 30000 psi on modern common rail fuel systems.
Learn Engineering couldn't you run gasoline safely in a diesel if you retarted the injection timing to after tdc? Wouldn't diesel spontaniously combust in direct injection gasoline engines? especially since diesel stochiometric ratio is slightly lower than gasoline? how is diesel in gas engine safe but gas in diesel engine not safe if diesel engine is more durable than gas engine?
Craig Kulig No, direct gasoline injection is still not widely dispersed as you think it is, most of the time injector is located just in front of the intake valve, not directly in cylinder, or its done like central injection, single injector being in middle of intake manifold, but its less accurate and requires more fuel than individual injection (each cylinder has its own injector, but its located in front of valve)..Long story short, direct fuel injuection is copying of how diesel engine works and applying it to gasoline engine to make them more efficient, but it has its own downsides, such as valve erosion, requires more often cleaning and so on..
MISTAKE
compression ratio is total volume divided by clearance.
Aakash Devadiga yesssss, Mistake
Yessss great video but great mistake
Andh bro..alakka wrong😂
The video is very informative, but just a small point, The compression ratio is Total Volume to Clearance volume 2:50

Thank you for your training
if the diesel engine is so efficient, why it is not used in sport cars ?
+Slimane AISSAOUI Because diesel engines produce torque typically from about 2000 to 4000 RPM, while gas engines produce their torque in way higher revs. That's why the gas engine has more power. You want the power in a sports car.
+Slimane AISSAOUI They don't generally respond to throttle changes quickly. They're great in endurance racing tho; over the last ten years, nine diesels have won the 24 Hours of Le Mans.
+jmowreader Diesel engines are not used in sports cars because they have lower power density.. because there maximum operating rpm is limited by the flame propagation speed
***** Nah, I just know a lot more about Diesel engines that most people can understand..
+HerkimerSnerd While the Audi R10 is very impressive for a Diesel powered car.. its performance for a 5.5 liter with 45psi of manifold pressure is not very impressive by modern racing standards.
This is due to the fact that the R10 can only rev continuously up to 5,000 rpm.. it can only overrev for a maximum of 5 seconds before damage due to overheating the turbos occurs.. above 5,000 there is not enough combustion dwell to completely burn the fuel this is due to the limited injection timing and high rpms that all Diesel engines are limited by.. the flame speed limits the propagation of the air/fuel mixture
Diesel sucks.
JMaster No it doesnt, it burns less fuel, which is cheaper, and thats all that it matters.
Of course diesel is good, but for military vehicles.
***** but the engines are loud and obnoxious. The ones in cars all sound the same, petrol is nicer and quieter.
dang my household all using diesel mini truck and all is running fine for a long time only a few maintainance.
And now our diesel engine can also using Natural Gas + Diesel Fuel to save more money lol. Noise and Vibration doesn't bother me while fuel and maintainance cost is quite cheap
+Ghost Each fuel type has its uses. Diesel is better for longer running and more torque driven applications, and gasoline is great for the racers and every day drivers. Diesel is louder because it is much higher pressure, and unless you get a Duramax Allison Chevy or a newer Ford, the engine will be loud.
