The gasoline example here is for IDI, aka port fuel injection, which is an old way of mixing fuel and air. These days, they use direct injection, which is the same way diesel operates, but there is still need for spark ignition.
I remember the hours I spent during my school days to understand how diesel engines work. I had only some images to support the theoretical portion of the book to understand it. Seeing this video brings back all those theoretical aspects to life, in a much more easily understandable manner. Thanks, Shell!
It’s because of the compression ratio. Notice how the volume of air in the diesel is way less at top dead centre, compared to the gas one which has a larger cavity at the top. A higher compression ratio increases the temperatures. If you had gas in an engine with compression ratios as high as a diesel, the fuel would ignite before it reaches the top and cause problems, potentially damage.
Diesel fuel is actually a very thin oil, whereas gasoline is a solvent - which is like the opposite of an oil. The extremely high fuel pressures in modern diesel engines require a high pressure injection pump. The simplest way to lubricate those pumps is with the fluid that they're pumping. Diesel accomplishes this very well. Also, diesel fuel has more energy in it than gasoline, so I don't think gasoline would be any better in the power/fuel efficiency department.
just imagine how millions of these combustions are happening each minute. and without them, we would still be spinning cotton by hand, and riding horses to work.
Millions? If you count every cylinder, a typical 4 cylinder rarely exceeds 14000 combustions per minute. 4 cylinders times 7000rpm divided by 2, as 4 stroke engine compresses every other rotation. Don't get me wrong, it is still impressive, but it's not that insane.
Now that I learnt something from you Shell, maybe I don't feel so bad with how much it cost me filling up my tank. Thanks faceless multi-national company!
A very informative video indeed. I like the animations, they really make it look very realistic! Now for two more of these informative videos complete with animations on how 2-stroke petrol & diesel engines work please. Thank you.
Very nicely made and well detailed 3D animation about the key differences in the operating method of a diesel vs petrol engine. The foundational difference is the presence of a spark plug in the cylinder head of a petrol engine which ignites the fuel during every cycle of the piston whereas diesel doesn't as it uses the principle of compression to detonate the fuel. This means that while the battery is only necessary to start a diesel engine and not to make it run, it is essential in a petrol engine as, without electricity, the electrodes wouldn't be able to generate the spark. Another difference I can think of is the fact that a petrol engine can use either injectors or carburetors, diesel only uses the former.
@@anthonykobiec8569 Yeah you need them in cold weather to start the combustion. When its cool outside, the intake air and the cylinder are too cold to ignite the diesel. In very cold places like Finland where I´m from, pretty much every diesel car also has an engine block heater that you have to use when it gets too cold, otherwise the glow plugs arent enough and the car wont start.
Wow, I have never seen a TH-cam video without a single dislike! (Hope I don’t jinx it). Great video and well deserved. There should be some TH-cam award for this…if there isn’t already.
After 7 years this video uploaded, me who only use TH-cam for gaming video and anime suddenly got this in my recommendation. Thanks algorithm, for giving me knowledge I will never use.
@@peterherrington3300 haha chill, it's a 1500 it has some power. I used to race thousand CC Japanese bikes, so trust me I do understand true power, nice busa by the way, but the Harley does what I need for me now, I don't go beyond 180 anymore, the Harley does about 120 LOL and I'm fine with that
The part that is often forgotten is how fast all this happens in real-time. A whole piston revolution happening up to 116 X per second (7000 RPM) on a fast engine, that really is mind-blowing

Greetings from a old timer
It’s always baffled me how something so volatile and light as petrol requires a spark, and yet something so unreactive and heavy as diesel doesn’t.

The accurate injection of fuel in diesel is also made by electronic operated parts
I believe some Diesel engines had “glow plugs” to help with ignition.

Fun fact: diesel is called “gasolio” in Italian while gasoline is called “benzina”
Yes. We are strange
In Polish we call diesel "Olej napędowy" - litteraly "Powering oil", or we also call it "Ropa", and for gasoline we call it "Benzyna"
@@Cristian88. it’s not only Italian, German use “benzin” and diesel, names are all over the place!
Similar in French, adds you might expect:
Gasoline = essence
Diesel = gazole
In Australia, UK, New Zealand we call Gasoline Petrol

That’s actually makes sense thanks for this video
Thanks. Now i know how a disel engine works
Highly detailed that i can see fuel cutoff 🔥🔥🔥
What about the glow plugs? Are they only used to heat the cylinder when you first turn on the car/truck?
This are the questions I am too lazy to search so youtube recommended it to me.
Very good video 🤩
What is more efficient?
So why the need for a different kind of oil? What is the difference between the oils?

Why does this matter, could you not have spark ignition for Diesel and compression ignition for gasoline?

I’m gonna strictly only use shell now.
That's just amazing.
Does the air particle collide with each other when it is compressed ? Is friction between air particle/atom happening here ?
It's the speed of each that creates heat, they bump each other and with the piston too.
I think.
