!?!HOW DOES A DIESEL ENGINE WORK!?! (Diesel Engine Working Principle) SCIENCE EXPERIMENT

Crazy Chris is checking out the science principle of the diesel engine and shows you how the diesel engines works with an experiment!

Objective: To understand how compressed air can heat up enough to create an explosive power stroke in a diesel engine.

FOR ADULTS AND SCIENCE TEACHERS ONLY
Materials Needed:
- Mug
- Candle
- Lighter
- Special Spray

Step 1) Light a small candle on fire and place the candle in a mug.

Step 2) Get some special spray and spray it over the mug with lit candle.

HOW IT WORKS:
The flame heats up the air around and above the the candle. This air gets very hot, hot enough to ignight a special spray. This is similar to how the diesel engine works. The diesel engines piston goes down which opens the air intake valve to fill the cylindar with air only. (unlike the gasoline engine which mixes fuel with air) The piston makes its journey back up and the air valve closes. This compressed air heats up to 650 degrees celcius hot enough to set the diesel fuel on fire. This creates an explosion pushing the piston down giving the power stroke. The piston makes it way back up once again to push the exhaust out of the cylindar and starts the cycle over and again. A glow plug is used to start the diesel engine but is shut off after the engine gets going.

my car has a diesel engine lots of cars have diesel engines

[Socoolscienceshow]

@thesparewheel some cars do have diesel engines but most of them do not.

[anime1973]

the heat helps... but diesel fuel ignites just because of the compression.

[Socoolscienceshow]

@anime1973 no the deisel fule doesnt ignite just cause of compression, its becuase the compression heats up the air hot enough to ignite the disel fule.

i wonder how your brain works

[mxtj3wboi]

Dude, great vid! I hope you don't let all the haters get you down. Keep on keeping on!!! XD

[LegitVisionz]

i want some of what hes on...

@salazaR6 Explosion in petrol engines? You are wrong, that's a flame front.

If it explode, you have a knocking engine....

[eightycc]

@thesparewheel Mine too:) In Europe they alllll have diesels:)

[chavcorsa]

clear a couple of things up, glow plugs are now also being used during the engine cycle not just in starting, in processes call pre and post glow. this aids in reducing diesel knock and increases efficiency, and at some other commenter's its a controlled burn in both petrol and diesel engines due to the homogeneous mixture, it starts at the source of ignition and burns out and down pushing the piston down.

@Socoolscienceshow depends on what country you are in and if you add it all up

@MrSTANGlover :D

[MrSTANGlover]

@Socoolscienceshow No, not really... you got me, I don't know anyone except the chinese guy who juggles the knives at the local Chinese buffett and Sarah Palin. But I was wondering if someone else did it. :)

Apart from all else, cool vid!
