Just think about, why Vin Diesel is not Vin Petrol... ;
Because he's the tallest Hollywood midget alive.
Poor Tom cruise
Cause diesel has more mileage
rocksteph84 😐
😂 😂 😂 😂
@@The-Cat How is 6ft a midget exactly? You godzilla sized fuck lol
When you learn more from a 4.5 minute video than an entire day at school
Edit: This is a joke dont take it seriously jesus, some people I swear...
You mean an entire chapter consisting of atleast 30 pages?
FSpotter you mean than an entire month in school
An entire semester, actually.

Petrol for fun, diesel for job
Dad is that you?
diesel4life nigga
You know nothing
@@Garolfa than tell me what you know
@@nurialco3303 Well, I know that my Jetta TDI with a 1.9 Liter was quite fun to drive. Granted it did cost a bigger turbo, 3bar map, better clutch with single mass flywheel, upgraded fuel injectors and a custom stage5 tune.
180hp + 311 tork while still running 6liters per 100km.
The thing that really made me like diesels is that you can create diesel fuel from almost any oil, like vegetable oil, or even used cooking oil (as long as you properly filter out particulates). It does have to go through a refining process, but you could essentially make your own biodiesel with oil at home if you wanted. That's cool! You basically just need oil, methanol, and lye, and some know how, and you can make biodiesel that can run in modern diesel engines with no conversion necessary (except if you have natural rubber seals, biodiesel eats through them so you'll need synthetic seals).
@@cgore4 okay boss
@@cgore4 That's your response? Implying that straining fuel and being able to put it directly into an engine equates to specialized equipment and years if not decades of experience? Yeah, you're the person who can't think outside of the box. If you can't say anything worthwhile don't say anything. Get back to your Starbucks soy latte infused life. Your commentary isn't needed
I didn't know that
@@cgore4 I've done my own dentistry and haircuts for years! Have all my teeth too!
bruh you can just use cooking oil out your chip pan and the engine still runs lol the oil is already refined to standard for such application as has already been tried and tested by the millions around the world :) ps if you over refine cooking oil you just end up with distilled water which is what you dont want in ur engine unless you wana fuck it up XD
Hands down the best explanation of not only petrol/diesel differences, but also of the strokes in a 4-stroke engine. So concise and simply presented. Well done, guys!
put a muted 2-stroke in a car and braaaaaap you never need a crappy 4 stroke ever again XD
The best 4 minutes in discussion that includes almost every detail in Engines
You forgot to mention that it is easier to start a petrol in winter, that's why most Russian big trucks run on petrol, so they can start in winter in Siberia
MadProductionsink block heater genius.
Its just as easy to start diesel in winter as petrol, just as long as the diesel has been winterized
meme lad not past -10F
GT20Modding it can as long as you have mor 911 mixture
meme lad Some people live in the desert like areas of Colorado where its not that cold but it gets down there once in a year and most people dont stock that stuff.
As a diesel mechanic I can tell you they are much more reliable and easy to work on. BUT you can’t beat the joy of a high revving gasoline motor.
1,5K dislikes are from people, that have electric cars
@Badger0fDeath bruh just because english people use a dot doesnt mean the rest of the world does too.
Badger0fDeath fack off
Badger0fDeath yes
Badger0fDeath no
Hah tesla
If this world starts going for electric cars, which it is doing, then in about 50 years, history teachers in school will use this video to show kids what it was like in the petrol/ diesel era
Luka Ohagei noup e cars are realy a ilusion
and jou can make a normal gasolin engine co2 neutral
with bio fuel
google power to liquids its interseting
Luka Ohagei 100% electric cars have low range. You need an electric motor to drive the wheels and a petrol engine/diesel engine to generate power.
multiestonian I'm sure what you're talking about there is a hybrid
Luka Ohagei Ups sry m8, i fucked up. Thanks for correcting me. ;)
Not everyone is going to want an electric car because they have far to many disadvantages
remember the other diesel video that Car Throttle posted but took down 30 seconds later???
they sure have changed their tune haven't they haha
jtpabst yep, they took it down so fast, I didn't see it.
I wanna see that one
What was it about?
jospi2 they were criticizing diesels and saying why the diesel engine needs to die
Audi 2.5 TDi 860.000 Km still running
Wtf? Thats awesome:D
Christian Scharff Wow! Road to 1Mil huh? :))))))
VW golf2 over a million.. just give him oil and replace filters it will go until you live
Thats because it's an Audi. Quality and german engineering are unbreakable 😜😏
Lol. Ask any Audi owner about the 1.8T engine. “unbreakable” my ass.
Also... what kind of km and how many a year? Most of what kills a car is age related deterioration. Internal corrosion, cold starts, gaskets aging and rubber and plastic components failing.
Finally... because it’s an expensive diesel, people put more money into them. If you put half the money into a gas car it would last as long.
I’ve had tons of very pedestrian cheap gasoline powere cars well over 500,000 km. It’s nothing special. Unlike the diesels that age without very major work... none were burning oil or making smoke.
Our company has several cars with the same model and year but different engines. The petrol one consume 1 litre per 7 km. The diesel one can go about 10.5 km per litre. I like diesel more not only the fuel efficiency but also its got more power going uphill.
Up hill is fun
And diesel sounds sexier hahahaha
however diesel is more polluting overall than petrol.
@@DSkulle1 not more than celebrities private jets
@@karanahuja6538 I mean it's not exactly a competition my guy.
I feel so smart after this.

I prefer diesel turbo charged engine definitevely!
Why?
You probably drive a golf aswell
I suggest you just to try turbo charged petrol engine. :)
With what over engine can you use performance, efficiency and reliability in the same sentence
In love with my PD130. Don't plan on having a petrol engine soon
I'm a fan of both the engines. 🙂
What’s it like being a fan on a diesel you just have to shift a lot of air ?
@@ryandurnin-footballanalysi3417 That's why most of the diesel engines have turbos.
but petrol have bad handling and dont last long.
@@Mahmi5 boy, that aint true
Damn centrist
You explained this video faster than a diesel engine compression. I got nothing
Was waiting for this comment
Watch with 0.75x
No noob would understand this in one go. Watch it again
Jjjaj I watched it in 0,5 speed and only then I could understand, but it is an excellent video.
He also somehow managed to not even mention glowplugs or add them in the Diesel diagram. How do you explain the difference between these engines without mentioning spark vs glow plugs??
Let the turbo kick in when you drive a diesel car, its sound, its torque will make you forget a petrol car...certainly yes i am a diesel engine fan
I guess you never have been in a 4.0 litre turbo petrol car that revs up to 8000 rpm
Diesel turbos are the best. Even with a smaller engine, they always put fairly loud turbos in them which makes them sound great.
Tfw you think turbo lag is cool
@@RazordraacGaming If your turbo is loud, its fucked.
Probably from running on that shitty diesel oil.
You would be surprised with how nice a diesel sounds WITHOUT a turbo. Now adays this is unheard of, but I have a 1991 Mercedes 300D (3 litre inline 6 naturally aspirated diesel engine). I swear, at higher revs, it doesnt sound like a diesel at all, because there is no turbo sound, it honesltly sounds like a 6 cylindre petrol, but it's throatier and raw. Might be an unpopular opinion, but I love it! Very distinct and full of character!

volkswagen tdi...
Heard they have quite good emissions as well.
KAL 1 we have one mk5 definitely not totally polluting the invironment with every start
this came actually from the americans who sued VW then. you know, USA, the country where they have fucking tournaments in producing exhaust gas with their 10 tons pick ups. ye they care about emissions lol
Shut the fuck up you rubbish idiot milking a 2 year old joke
The NOx emissions weren't that much higher than they proclaimed.
Still not good that they cheated with a couple of lines of code instead of actually making a car with lower emissions.
They could've done the recall in secret and no one would've noticed.
panzerveps can't secretly do a recall, it will hit the news eventually
This is a simple and perfect animation to understand the difference between petrol and diesel engine.
a 5-minute video literally helped me understand a lot, not only with regards to the differences between diesel and petrol engine, but also with regards how the 4-stroke cycle of an engine works. kudos to you good sir! thank you for this very informative video.
Just completed the first year of my engineering degree at uni. A big chunk of the Thermodynamics module was based on the differences between the Otto and diesel cycle. CT got it spot on. Aspiring engineers, listen up.
I think these videos are some of my favorite
They educate in a very entertaining way and give us the sweet, sweet data all us nerds crave
Very helpful, thank you RUclips for the recommendation!
How can I only be finding this out now.
Where have I been all my life
From an engineering standpoint, the diesel's are way better due to the higher thermal efficiency. Now if we could do a diesel cycle with gasoline rather than an Otto cycle... that would take the cake
Look up what mazda is doing with this, they are on the brink of creating that dream, a high compression petrol engine at high speeds and a spark plug for the cyclinders to use at lower speeds = the best of both worlds!
Diesel engines don't really use the diesel cycle but rather the Sabbathe cycle. Mostly the same but the expansion after ignittion is done in two parts i.e. partly with constant voliume and partly with constant pressure
Can you do a turbo vs supercharger ☺️
diesels do better with a turbocharger because of the high compression it will drive the turbine blades better and will lite both chargers for better boost and the diesel will get more torque that way but superchargers rob a lot of power from the engine to spin them for the air pressure into the engine
chris mchenry petrol doesnt need that much boost die the same hp. give a petrol the boost the diesel has and it will fly.
diesels are more built for torque and pulling and are not made for speed that is why the power curves between the two engines is the opposite and a diesel has got to get to 1000 rpm before it starts making its HP where a gas engine can make it at a lot higher rpm`s versus the diesel but the diesel wont stall as fast under heavy load like the gas engine will because of the twice as much compression
Why do the fastest cars in the world use superchargers and not turbos?
The Bugatti Veyron and Chiron both run 4 turbochargers, not superchargers. The Hennessey Venom GT is a twin-turbo. F1 cars use a turbo. The land-speed record for a piston-engined car was in a turbocharged V8.
Which world are you talking about?
The best 4 minutes in discussion that includes almost every detail about Engines
One should point out that, although some newer diesels do have a throttle body/valve, it's not actually required for engine operation. Vehicles that do have it use it for allowing efficient EGR operation, smoother engine shutdown and sometimes help with engine braking.
Diesels can't actually restrict airflow like petrol engines during normal operation as any significant decrease in airflow will reduce ultimate compression pressure below minimum and hinder fuel ignition.
Thus throttle valves only operate during engine coasting (to help with EGR) or during shutdown (to reduce piston knock back as the engine stops) and in some other specific scenarios.
AMAZING. Held back on learning about automobiles most of my life bc the mechanics I knew were too grumpy to explain. You, sir, made it easy to digest! *Tips hat*
Very clear and nicely animated explanation! Great job!
your animation and visuals are amazing ... Loved it Really
Incredibly simple explanation. Thank you.
I own both a Turbocharged Petrol (2005 1.5T Mitsubishi Colt CZT) and a Turbocharged Diesel (2016 Seat Leon FR 184 TDI with a DTUK Tuning Box) car. Personally, I prefer the Diesel, boost kicks in way sooner (1800 RPM in the diesel, around 3500 in the Petrol) so it's great for overtaking and just in general driving such as pulling away from Junction. However I always make sure to only use the Diesel for longer journeys and the Petrol for shorter journeys to shops and such as the DPF getting clogged can be a big problem with the Diesel if you're not driving it often and long enough.

NeoSilvanus ...and Jeremy Clarkson looks like one 😄
NeoSilvanus little does he know that ships are powered by diesel instead of petrol. Scania, a world wide producer of trucks has the popular and last v8 truck engine wich can also be used as a boat engine
@@steve5825 someone's salty
@@JJ-iy8dx reckon its just a joke containing no salt really
Great video for explaining the very basics of the differences!
Quick and concise. Loved it!
Higher compression ratio also means higher expansion ratio. This means that more of the explosive force is used for pushing the piston down (and hence making the car go forward) rather than getting blown out the exhaust. This is similar to how under-square engines are more efficient. Its all about leverage.
veryyyy well explained !! really interesting video and so simple to understand . Loved it ! So much information in such less time . Please make more such videos. Just subscribed to your channel ☺
Nice work and excellent explanation of differences.
Great video, good explanation of how it all works! Deserves a sub for sure.
simple:
if you hate people, drive diesel.
if you hate environment, drive petrol.
if you bit selfish and hippy, drive electric.
electrics wont differ much on pollution... depending on their life cycle from production to scrap.... or what will electricity factories need to burn to charge thousands of electric vehicles... its still plenty of Co2
Alexander Mouzakidis factories need to burn to produce gas and oil. Factories need to burn to produce gas and diesel vehicles.
Electricity, soon enough, will come from clean sources.
Your argument is invalid.
Yeah. Global warming is bullshit anyway.
What if you hate them both?
I hate people abd kove the enviroment. I FRICKEN LOVE DIESEL
Forgot one fact! Diesels can turn into "runaway diesels" where the engine revs uncontrollably up to even 14000 rpm because of faulty gaskets in the turbo feeds oil into the engine causing ignition, turning the key won't help because the engine runs on oil now and not on diesel, so the only way to stop a runaway diesel is to either starve the engine of oxygen by taking a wood 2x4 covered with duct tape and putting it on the intake manifold so there is no air entering the engine or by holding down the clutch and brake pedals putting the car into the highest gear available and dropping the clutch and pressing the brake pedal hard so the engine stalls. Anyway hope you never get to experience a runaway diesel this has been education time with Vault-Tec Representative goodbye
Is that what Honda fanboys call VTEC?
vtec just kicked in yo
This is why you get your diesel checked out, or just run an NA diesel like a few of us do. I myself am gonna run an NA Duramax in my towing rig once I can afford it because of this problem. If your vehicle has a likelihood of doing this, then get the gasket replaced. It's that simple. (and my diesel is going to be a manual because of this problem. Although I'm going NA it's still better to be safe than sorry.)
*cough* Renault 1.9 dCi 120 *cough*
Wogden 700 its better to change your clutch that your engine right?
Very Good explanation
Nice brief explanation.
There was a significant improvement in diesel's performances when commonrail system was introduced so they are now providing extra power and fuel economy as well as fully optimised work. There is a nice statement which says: where diesel stops, the petrol continues (regarding to high revs performances).
one of the most fun "cars" I've ever driven was a twin-turbo diesel v8. loads of torque, and the sound of the turbos was gorgeous
Big truck i am assuming
This was great, thank you.
This was awesome. Thank you kindly for the information
diesel for every day use, petrol for joy rides
Lijevi Desni short and sweet
Lijevi Desni. u r right.
diesels do both
Wait, why?
Why
1 is loved by Seat owners and the other by the rest of the world?
I chuckled
NELKEL JDM VLOGS hey bro didn't expect to see you here
NELKEL JDM VLOGS Yeah. My dad owns a Toledo, and he's a fan of diesel xD
glad that I glanced at the comments section . Thumbs Up
So true.
Great video, thanks
Thank you brother,today i learn the difference,👍👍
Short trips - Petrol
Long trips - Diesel
what can i say true also my dads car is diesel
Short trips - Diesel
Long trips - Diesel
Even if not on trip - Diesel
i cant say anything just i can agree with you pestrol on short distances is better but Diesel on long distances is way better because the engine can heat so compresion is better so there isnt needed a lot of fuel to have big power :)
Even shorter trips - Electric
moped
Slight issue, diesel engines make more torque because they have a longer stroke, which is in turn due to higher compression.
longer stroke means the the piston is acting on a longer lever to turn the crank shaft, so more torque.
Brilliant explanation, thanks so much! :)
Thanks for the info about engines
I'm a fan of both. I own a diesel and a gas vehicle.
maxxjett films why do Americans call it gas exactly?
dylan fourie
just always have, just like I thought it was weird to hear someone call a trunk the boot for the first time. As I have immersed myself in different car cultures, I find it normal. Although I still prefer to call it the what I grew up calling it
dylan fourie - To be fair, I'd say gasoline (Gas-O-Leen) written out in full seems more American
You guys should really call it for what it is Bensin/Benzin because it contains Benzene. Gasoline is a made up term and Petrol is unrefined oil.
j0wt0ng No we don't... Very few vehicles use LPG now.
Diesel for Tractors and heavy duty vehicle.
what about race cars?
Thanks instructors for proper instructions.
To sum it up Diesels are more efficient, have more torque, are more reliable, are simpler, have more torque at low rpm and the fuel usually costs less (depending on where you live)
Petrol on the other hand sounds better, are generally lighter, pollute less, and the maintenance costs less
DIesels are simple ? WTF are you talking about ?
Daniel G diesel emits less co2
less co2 but more of the other shit gases
I might differ on reliability issues
Diesel pollute less, they use less fuel
2:52 - The jake brake only opens the exhaust valve when the piston is at top dead center (or if it is an interference engine, just after the piston starts going down so there is clearance), because leaving the valve open through the entirety of the compression stroke won't have the same effect.
Thank you, good explanation
Thanks for the vid! :D
one VERY important thing about the diesels hp and torque:
without a turbo, a diesel has roughly as much torque and hp as my electric toothbrush.
99Lezard99 so your toothbrush got 120 hp and 240 nm?
patrik persson what size is the engine you are talking about? and yes my toothbrush has about 125hp and 250nm and is powered by a 9.7 liter straight 6 n/a diesel.
99Lezard99 wouldn't that be a diesel toothbrush?
Aleksey Gladysh yes. seriously. if you have ever driven a diesel without turbo you know what im talking about. for example: my mother used to own a Mercedes 190d witch had 2.0 of straight 4 n/a diesel goodness with mindbending 75hp and 130 or 140nm of gutwrenching torque. a 1.0 45hp corsa was quicker. my first car was a 90hp 1.5 petrol and it felt like a rocketship compared to the 190d. my second car was a 2.0 petrol with 133hp and 180 or 190nm and it felt like timetravel compared to ye good ol 190d. after driving that 190d for a while i knew exactly what i didnt want in a car.
99Lezard99 Mercedes om603 6 cylinder 3.0 liter
You should make a video on which car company owns what.like BMW owns rolls Royce and stuff like that. Although it can be searched online I think a video showing what all the major car companies own would be pretty cool.
Brian Aguilar everything is owned by Germans and Japanese
?
Nice explanation . Thumbs up 👍🏼
Best explanation
Thanks guys! My wife and I are looking at buying a cheap car to drive around Europe soon, so we're absorbing all the information we can find online😅
i drive a 6.7 turbo diesel and i LOVE it
Great description bro ❣️
diesel has more energy per litre, but it's also heavier. the amount of energy per kilo is about the same between diesel and petrol.
Perfect explaination fr mechons ... 😍
And there I go to give this video a lovely thumbs up 👍!!!!!
thank you......you saved my day
You guys need to get into the online education business - some fantastic clips here, which explain the petrol and diesel concepts really well.
Niall where ?
I love both engine types. Some diesel engines have a massive pull out power which makes them just as fun as petrol. Also diesel is generally immune to knocking allowing easier power boosting.
For team diesel I have a mitsubishi l200 animal with the ralliart power upgrade.
While team petrol is a mazda 323f zxi v6
Great video man
I had both and for me winner is a diesel. It's more comfortable and for daily use and long trips is simply better. I have Audi A6 avant 3.0 TDI quattro 180kW and I love it !!!!!
Could you do a version for Compress (and/or even Liquid) Natural Gas?
I am well aware it's been a couple years
Could you have made your comment without the extra line breaks, forcing the reader to click "read more"? I'm aware that your post was over a year ago.
Great video
thanks this really helped
for me it depends entirely on application
Hello one of very few reasonable people in this comment section. So many people here hate on diesel, but couldn't live without any of the things that are regularly brought to them by diesel powered trucks, or the food farmed with diesel powered tractors and combines. Both fuels are great, and each has it's application.
Exactly, for you and for everyone. It is a fact.
My brain is dead

Goldfish.
wow great video, good visuals.
Worth watching
I usually love the engine which roars like a Trex 😉
I love both engines, in different aspects.
Good one
well done
Diesel engines use glow plugs to ignite the air fuel mixture when starting up before switching to air compression for igniting the air fuel mixture. Because diesel is not volatile as petrol it does not give off vapours thus it is very hard to ignite when the Diesel engine is cold, especially in winter. I will stick with petrol since my winter season can be -30 degrees Celsius.
Super early squad!
Always been a gas/petrol guy until here recently and am also a big fan of Ford trucks. Just got one with the 7.3 powerstroke diesel and have realized what I’ve been missing out on
nice. thanks a lot
The point of the turbo (3:56) is to pump more air in the cylinder. In a diesel you can pump as much as you want (the more, the better). With petrol you are limited by the stoichiometric ratio.
Uh... no.
The stoichiometric ratio is just a air fuel ratio for complete combustion of fuels. For gasoline it’s 14.7:1. For diesel it’s 14.5:1.
With either of them.... if you put more air in, you put more fuel in.
Gasoline engines are generally limited by detonation. But although Diesel engines don’t have that limitation they are already running huge compression ratios, high heat, and insane forces on the dynamic components.
Adding too much boost will destroy the engine as surely as a gasoline engine. This is why in tractor pulls they run super rich (smoky) mixtures for cooling, and have quite spectacular failures. That’s also why you want to avoid any chipped or modded Diesel engine like the plague.
Bartonovich52 What you said is all correct, however you have to press "Read more" to see the full reply. I tried to be short on purpose. That said: Of course, you can just add more fuel to maintain the stoichiometric ratio, however (as you said) this will lead to engine knock IN PETROL engines. Not in diesel, since it only compresses air. And of course you can't just pump in an unlimited amount of air, because it would blow up the engine (both petrol and diesel).
I never been a diesel engine fan but from now i became die hard fan of it
Well explained tanq sir
Fine teacher
When your teacher explains the most complicated equation in the class and everyone else says they get it and your just sitting there having no idea
I need a video that explains this video ...
Well explained I really liked it.... :)
