Diesel engines are the most versatile IC Engines. With help of animation working of Diesel engine is elaborately explained in this video. Here the basic construction of diesel engine, its working and mechanical design aspects are covered. Starting from working of single cylinder diesel engine, working of a four cylinder engine is logically explained here.

I heard Destin in his carburetor vidoe use a phrase that I will never forget (also partially why I'm here now). He said the way he remembers the 4-stroke steps were "Suck, Squeeze, Bang, Breathe." I'm still unclear on how you actually "start" a deisel engine without spark plugs or a lawnmower rip-cord to get the compression cycle going, and so, the quest for knowledge goes on. But loved your comment friend.

[@zebracherub]

This moment when you realize 4 cylinders are because of the 4 strokes and to offer power continuously. I feel illuminated.

[@2ddd2]

zebracherub Well keep in mind there are still 6 and 8 cylinder engines. I'm just a novice, but I think that as long as some push up and some push down it would still work. Even a set of 2 or 3 pistons on engine. One cylinder per step isn't necessary, but two pushing down while two push up probably makes it easier to run smoothly.

[@cloroxbleach118]

Zerumphrey Chocolate you are correct. Many dirtbikes for example, only have one piston with a set of valves and a spark plug.

[@Quietbut_Deadly]

Typically even in single cylinder engines they go so fast even 1 stroke at a time you don't slow down

[@demiank]

I think that engines that use less than 4 cylinders use another type of mechanism, the 2-stroke engine, though i am not sure

[@vsop3338]

One of the best selling diesel motors in history is the 5 cylinder OM6## series powering the majority of Mercedes sedans and coupes worldwide throughout the 70's and 80's.

I used to own a VW Diesel Jetta TDI. Never had any issues in obtaining diesel fuel most places. Actually had more get up and go (torque and HP) than diesel cars I rode in back in the 70's. Quieter than the 70's. Cleaner at least when VW wasn't cheating on emissions tests. Was a party to their settlement.

[@toddmintz4269]

@@AverilDoyle So they aren’t labeled wrong, you’re just saying the timing is off?

[@AverilDoyle]

I'm saying it isn't an exhaust valve if it is not exhausting. Clearly, it will not run if it is 180° out of phase and is doing a very bad job at what is supposed to be doing. Additionally, not all diesel engines are intake on the engine's left and exhaust on the right side. 2 minutes of googling came up with the Kubota V2203 engine. Intake cams are on the right side instead of the left. The point still remains that their animation is wrong, so I'm not really sure why you are trying to split hairs.

[@choiceemamodeonofeghara3012]

This is the first time I'm having a comprehensive undesrtanding of how an Engine works. Well made video!

[@shubhambhavsar4237]

simple and effective video without any timepass. thank you so much

[@petergambier]

Thanks for this clearly explained process. The other day when out walking the dog I found a diesel glo-plug out on the road. I was quite surprised to find one as you can see by the threads that it would be quite well fixed into the engine head, as a result of finding it I was curious to see how they worked. This is the 1st time I've seen how the diesel process works and I noticed that when the upstroke gets to the top there is bound to be some residue left behind which then mixes with the new intake of the airfuel mixture. Wouldn't you get a more efficient and purer fuel mix if you could expel all the old burnt fuel on the upstroke expulsion or am I talking a load of bollox and it makes no difference to the airfuel mixture ratio?

[@DarrenBoss1984]

Some engines recirculate exhaust gasses back into an engine to allow for lower emissions. The idea is that the high temperature burns off the excess particulates in the exhaust gasses. If you look for EGR valve it might be clearer than me explaining it.

[@Rudxain]

4:31 this reminds me of pipeline CPUs. At 1st I thought of each piston as its own independent "CPU core". But it seems all pistons are just a single pipeline core. In CPUs, pipelines are used to use time efficiently (better speed and energy use, but less cheap), while engines use this "pipeline" for a smoother motion, while (as a secondary consequence) increasing total power a little bit more. In a sense, this is like a quad-core CPU where each core contributes to processing a single stage of a "global" (shared) pipeline. The fact that the pistons share the same axis of rotation and are synchronized, is like all cores are driven by the same clock generator! which is common in old CPUs (newer CPUs use independent clocks to save energy and produce less heat)

I love the diesel engine, so efficenct and powerful, they are capable of some extreme amounts of mileage with very little maintenence other than regular oil changes etc

[@VergilThe1]

Truly Emaculate

[@JustWasted3HoursHere]

I remember hearing that tractor trailer semis were not even scheduled for internal maintenance until around 500k miles. Don't know if that's true but they definitely are more efficient than petrol engines and likely last longer because of the required heavy duty internal structural support mentioned in the video.

[@lazyman5096]

@@JustWasted3HoursHere There has been diesel engines with 1 milion kilometers on orginal internalas like the 2.2 l cdti from mercedes or 1.9 l tdi from volkswagen.

[@JustWasted3HoursHere]

@@lazyman5096 It's kind of counterintuitive too, because when a diesel engine is running it sounds like a someone threw a bag of rocks into a washing machine. But I think the trick is that the block and substructure has to be made stronger which is why it lasts longer. I'm not sure if that's the reason they last longer though.

You forgot to mention the origin of the engine’s namesake. It is invented by a German mechanical engineer, Dr. Rudolph Diesel in 1892. He described it as a “compression ignition heat engine”. With the “diesel” engine named after him, his legacy lives on! 🇩🇪 ☝️.

[@MrStickyJkey]

who has ever said.. "I love my Vauxhall whatever" your first mistake was the car..

[@dailyvlogs1082]

upload a video how a car initially starts using a key

[@esowaych]

Cars have a small electric motor called the "starter motor." When the driver turns the key to start the car, the starter motor uses battery power to rotate the flywheel and crankshaft. Once the engine is rotating, the 4 stroke sequence begins, the engine fires and begins running and the starter turns off.

[@carbonz1995]

What and where are glow plugs and how do they fit into this?

[@jorgevasquez8046]

+DANGEROUS DAVE Glow plugs are screwed directly into the cylinder like spark plugs. but they are only used for cold starts.!!! the tips get super hot before starting of engine to help heat up the combustion chamber and air that is in the cylinder. This way you minimize hard cold starts especially in really cold weather!!

[@pranavdna]

Does that mean, there are no spark plugs in diesel engines?

[@NorwayVFX]

Pranav Tembe Correct

[@NorwayVFX]

Glow plugs only warm up the inside of the engine before starting, so that it is easier to start when it's cold. They aren't used when the engine is running.

[@raghavaneti5589]

Gh

[@Shadow0fd3ath24]

Glow plugplugs get it running, and then from there the compression and the silver piece on top of the pistons you see at the beginning keep hot so that it us ignited by heat and compression alone

[@WayToManyAssassins]

Pranav Tembe Yes but instead of spark plugs, they have diesel injectors.

It's not an explosion but a combustion. Two different things...

[@RafaelBenedicto]

"explosion" is an umbrella term used for any physical or chemical reaction that produces rapidly expanding force.

[@PeterSosinski]

@@RafaelBenedicto not as I understand it chemically. The chemical properties and resulting outcomes are quite different between a burn and an explosion. It's a point often glossed over and frankly not that important for most to understand the concept of ice. But it would be the equivalent of saying look at that camp fire explode, or the burner is exploding.
