Diesel works on witchcraft

[@TheyCallMeMrMaybe]

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.

[@Nafeesdrmc]

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!

Glow plugs heat up the combustion chamber in extremely cold environments. Diesels need heat to run, glow plugs simulate heat.

[@xygomorphic44]

They left out one critical detail. When youre using Shell's fuel, a small amount of the exhaust gases turn into carbon which then gets deposited onto the top of the piston where it builds up and destroys your engine.

[@droy333]

What about 2 stroke diesels?

[@rawbacon]

Great but they still smell, my Dad bought a new tractor and although better than the old diesels the exhaust still has that diesel odor and the fuel's not cheap like it used to be.

[@sekousuperdiabate1853]

[@niradnagrom2356]

One thing I didn't learn in this video is how a cold started diesel stays running without hot air to evaporate the fuel spray. I'm assuming les fuel may be sprayed in a cold start and then progresses as the engine warms. That's the only way I can understand a cold diesel engine staying running after being started.

[@kavishkaanjuna3268]

Is it possible to use diesel engine machanism on gasoline engines?

[@Bendigo1]

They already use similar mechanism, the problem with gasoline is that it does not combust like diesel, it needs a spark or flame to ignite it.

[@ryanjones7681]

Where's the ignition coil at?

[@haikalmiftah2529]

[@apoorv2498]

Pros: This is engineering making life easy Cons: pollution, carbon emission

[@WeonKewHann]

Actually diesel fuel burns at the boundary surface of fuel spray. The combustion does not occur in the entire space of combustion chamber. That is the biggest difference between diesel combustionand this video. The host of this video should see the visualization of diesel combustion system.

[@ЯрославШевченко-х7й]

Wrong. In fact, the exhaust valve opens before the piston reaches its lowest point in power stroke. And the intake valve closes later than the piston begins to move up on the compression stroke.

[@tech_commando]

Precise

[@blackice7408]

Well what makes diesel engines make that loud cladding noise it makes?

[@ludwigvonn9889]

Well i still have a hundred questions. How and why does air heat up and explode without a spark... why is diesel still cheaper and more economic, and why do diesel engines dont have the same power as petrol ones... why does the petrol engine need a spark if the process is 90% the same as in diesel - air being compressed and heated, mixed with gas... This didnt really answer anything for me lol, but its a good representation of the basic mechanics, thats true.

[@achim07]

Gasoline is much more stable and therefor requires an external source of energy to spark the ignition. Chemically speaking both fuels are just carbohydrate chains. The longer the chain the 'quicker it can break' Gasoline is very short, Diesel is longer. High pressures and temperatures are enough to ignite Diesel fuel. If you put gasoline in a diesel engine (do not do this) it would not ignite (and cause serious problems). Engine power = torque x revs, Diesel engines don't rev as high as gasoline engines, therefor are less powerful (even though the difference is negligable in modern cars). 'How and why does air heat up and explode without a spark' - the air alone does not do this, only when Diesel is added right before the piston is at top dead center. 'why is diesel still cheaper and more economic' - more economic because the compression ratio is much much higher, thermodynamically speaking efficiency is a function of compression ratio.

[@almelkinspeco]

how does a regular diesel differ from V-power diesel? is there a difference on how it is burned or does the engine work differently? pls enlighten me. thanks

[@daveworthing2294]

It's cheaper!

[@НиколайНикакоюс-л2ь]

Diesel doesn’t burn like gasoline and won’t ignite from a spark but the heat from the high compression will

[@colt10mmsecurity68]

Good video but a direct injection gas engine is different and….. it sucks. The fuel loaded with detergents can’t keep the intake valves clean like a traditional air/fuel valve gas engine can. That’s why direct injection engines get serious trouble after so many mikes and run rough, while cleaning the fuel system is much more expensive to do. I hate direct injection gasoline engines for that very reason.

[@YelpBullhorn]

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.

[@Michael-fr8gy]

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.

[@emmanuelquerol]

@@Michael-fr8gy why not use gasoline in a diesel engine?

[@JayRussellDuramax]

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.

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.
