Just think about, why Vin Diesel is not Vin Petrol... ;

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).

Petrol for fun, diesel for job

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.

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...

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!

Audi 2.5 TDi 860.000 Km still running

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.

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

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

This is a simple and perfect animation to understand the difference between petrol and diesel engine.

I'm a fan of both the engines. 🙂

remember the other diesel video that Car Throttle posted but took down 30 seconds later???

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.

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.

How can I only be finding this out now. Where have I been all my life

I prefer diesel turbo charged engine definitevely!

I feel so smart after this.

Very helpful, thank you KZfaq for the recommendation!

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.

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 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

your animation and visuals are amazing ... Loved it Really

The best 4 minutes in discussion that includes almost every detail about Engines

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*

Can you do a turbo vs supercharger ☺️

1,5K dislikes are from people, that have electric cars

Great video for explaining the very basics of the differences!

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

1:42 volkswagen tdi... Heard they have quite good emissions as well.

You explained this video faster than a diesel engine compression. I got nothing

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.

Very clear and nicely animated explanation! Great job!

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

Incredibly simple explanation. Thank you.

Quick and concise. Loved it!

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 ☺

"diesel engines sound like a canal boat" - Jeremy Clarkson

Nice work and excellent explanation of differences.

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).

1 is loved by Seat owners and the other by the rest of the world?

Great video, good explanation of how it all works! Deserves a sub for sure.

This was great, thank you.

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😅

You guys need to get into the online education business - some fantastic clips here, which explain the petrol and diesel concepts really well.

This was awesome. Thank you kindly for the information

Great video, thanks

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.

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

Brilliant explanation, thanks so much! :)

thank you......you saved my day

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.

diesel for every day use, petrol for joy rides

Great description bro ❣️

Thank you brother,today i learn the difference,👍👍

Short trips - Petrol Long trips - Diesel

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.

And there I go to give this video a lovely thumbs up 👍!!!!!

Thanks for the info about engines

i drive a 6.7 turbo diesel and i LOVE it

Diesel for Tractors and heavy duty vehicle.

Very Good explanation

wow great video, good visuals.

I usually love the engine which roars like a Trex 😉

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

Thanks for the vid! :D

Nice explanation . Thumbs up 👍🏼

I'm a fan of both. I own a diesel and a gas vehicle.

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.

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

Great video man

for me it depends entirely on application

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 !!!!!

Great video

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

Could you do a version for Compress (and/or even Liquid) Natural Gas? I am well aware it's been a couple years

Thank you, good explanation

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.

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

Nice brief explanation.

thanks this really helped

Perfect explaination fr mechons ... 😍

I love both engines, in different aspects.

Well explained I really liked it.... :)

Best explanation

Next video idea : The Diffrencees Between a Turbocharger And A Supercharged vehicle

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.

I bought a 30 foot yacht with a Penta Volvo diesel engine and was told tank was full (100 litres). I had driven it up and down Gold Coast Australia coast for roughly 10 hours. I thought I'd better put some diesel into the tank before my next trip. So I filled up a 20 litre container & started to empty it into my tank & I couldn't believe it. After about 7-8 litres , the tank was full. The only downside to it all was I mixed about 50 mls of Diesel cleaner into container & being so efficient, most of that cleaner is still sitting in container yet to be working its magic. love diesel.

Thanks instructors for proper instructions.

Great info

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.

I need a video that explains this video ...

I forget that diesel cars are a much more common thing overseas lol. I kept expecting to see some type of heavy duty truck throughout the video. Great video btw.

Golf 2 1.6 TD here, almost 1 mil km passed still running strong.

And its much easier to modify turbo diesel engine than petrol turbo engine, compression is the key

Mercedes Benz E300 turbo diesel, unbeatable 26 years 300.000 km and still running

Good one

well done

For me (since i am from India ) I would pick any of the below engines and these are my favourite ones:- 1)Honda Ivtec - Petrol 2) Toyota 2NRFE - Petrol 3) Fiat 1.3 L Multijet - Diesel 4) Toyota 1.4 D4D - Diesel 5) Ford 1.5 TDCI - Diesel 6) Renault 1.5 L DCI - Diesel

I never been a diesel engine fan but from now i became die hard fan of it
