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!

[@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.

[@Amnok]

Finally my first respect on Shell

[@Vylkeer]

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.

[@EvgenyMurashkin]

The accurate injection of fuel in diesel is also made by electronic operated parts

[@anthonykobiec8569]

I believe some Diesel engines had “glow plugs” to help with ignition.

[@benqqu]

@@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.

[@solublesquid5871]

RUclips decided to reccomended me this today.

[@SubtractZero]

I try to explain to people that firearms and ICE engines work on a similar principle, but nobody seems to agree.
And ICE engine is essentially a firearm that harnesses the projectile (piston) into a rotational motion using a crankshaft and connecting rods. Gunpowder is swapped for a combustible liquid, an aerodynamic projectile is swapped for a flat piston, an open-sided rifled barrel is swapped for a short cylinder, and the single-use primer is swapped for a reusable ignition plug (spark/glow).

[@sansyboy4181]

I noticed, being able to link things together things from disparate fields is a sign of intelligence and how inventions get made, keep it up.

[@TheFlynCow]

is it expelling a projectile? no.

[@Old_Joseph]

@@TheFlynCow neither does shooting blanks, but it’s still a firearm…

[@TheFlynCow]

@@Old_Joseph its still a device CAPABLE and MADE TO expel projectiles. A Signal gun only capable to shoot blanks is not a firearm.

let the history remember

[@possibleimpossible3359]

It was found that the ethanol-glycerol blend at the ratio of 3:1 (75/25%) can be directly applied as a substitute fuel for either gasoline or ethanol in internal combustion engines in the automotive and power industry.

[@jaydenritchie1992]

Common rail diesels inject upwards of 7 times per combustion cycle. The ecm controls the injectors duty cycle from 0%-75%

[@guyunknown9123]

But how does this happen when we enter the key into ignition and the engine is at a stand still idle state. How does the piston start moving from idle ?

[@lakewoodbball]

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

[@flintbrantley7903]

This are the questions I am too lazy to search so youtube recommended it to me.

[@exitium194]

Trying to figure out why 1: This video was recommended to me 5 years after I last looked up how combustion engines work for uni, and 2: every single video on the side has been replaced by ones uploaded by Shell even though some of them only have hundreds of views. Looks like more slimy money gushing into Google's account again...
