4 Cycle Internal Combustion Engine - Mechanical Parts

[ghousevil]

common man its called 4 stroke engine.... not 4 cycle dude :)

4 strokes= 1 complete cycle

[onewingedangel326]

@ghousevil actually its 4 cycles = 1 power stoke.

[ghousevil]

@onewingedangel326 okzz.. thnx for info

[lunaod1]

1 thing i didnt like... Engines don't suck.



[6kubo9]

really good video.

this may be a dumb question, but when the explosion occurs in the cylinder where does all of the energy go to allow the car to move?

[Apoc897]

@Rocketpocket95

Crankshaft pulls the piston down which, in all truth, is being PUSHED down by the "explosion", or combustion inside the chamber. That power is in turn transferred to the axle or to a differential (special set of gear wheels) that transfer the power to the drive shaft or wheels (depending on whether the engine is front or rear located).

[Frederik19951995]

I have a question: What about the vacuum in the crankase, when the piston moves up??

vaccum in crankase = Makes it difficult for the piston moveing up ?? Am i wrong?

[MusicoConfundido]

@Frederik19951995 It's no longer a vacuum because the exhaust valve is open.

[cycle454]

@Frederik19951995

most engines have many cylinders and this is not much of an issue. and even in this case you should get most of the energy back. im not an expert though

[djsingh23]

rsobhee@ -- Look over somethin called 'Cams' in Wikie or Google :)

[rsobhee]

What I do not really understand is how the whole system works independantly.. i mean.. how does the valves move? by which mechanism...to make an automated system where the only energy source is from the fuel.. so I do not know how the valve mechanics get connected to the piston mechanics.. so I do not understand the " clockwork" mechanics.. how does it all move together is not clear to me...

[MusicoConfundido]

@rsobhee The valves are opened and closed by a system of cams on a rotating shaft called the camshaft. The camshaft is connected to the crankshaft by a drive belt or chain. Thus, as the crankshaft turns by the action of the pistons and connecting rods, it turns the camshaft, which opens and closes the valves. More fuel is admitted to provide energy to move the pistons. The entire system is interconnected.

[rsobhee]

@MusicoConfundido Thank you a lot for the explanation. It is very well explained by you. I am a biologist but I was interested to know how an engine works but none of the videos here and elsewhere explained this part.This helped. Thanks to djsingh23 as well.

[MexicanJudge]

what happened to your finger?

[TheRandomSkillz]

About time an actual good video on this stuff. THANK YOU!

[robertking13]

very helpful cheers.

[cuecumber22]

What makes the piston compress?

[TheJoecool1972]

@cuecumber22 the crankshaft

[phantom5573]

Yes. Thank you

Hi, you explanation about crank shaft and cam shaft clearly shows inlet and out let of fuel and emition but can you explain little bit about the spark plug too, what causes spark plug spark is it timed mechanically or computerized how is it timed ?

[bobodd5]

fukked

[thedamgame]

great video,,,im taking it this semester

How to better the gasoline internal combustion engine.

1. Dual Real Cool Air Filters.

2. Dual Oil Filters with larger oil pump. (OMG!!)

3. Supercharged and Intercooled.

Thank you for your video.

[myastroflight]

@19mg94 Some peeps didn't like the comment and spammed you.

Back in 77 I joined the Navy as a driver. The civilian drivers were all male; we military drivers were all female. We were trained in automotive engineering by the Air Force. The workings of the Internal Combustion Engine - that is EXACTLY how we were taught, "Suck, Squeeze, Bang, Blow". It was hilarious and we never forgot it. Clever instructors use what ever tools are necessary to instruct, even low humour.

Get over it people.

[19mg94]

@myastroflight ithought it was funny.dont mean a thing by it and i dont care what other people think about it lol

[nemanume]

what is the name of the designe program ?

[gillendk]

great video, this extremely simple, however fully detailed explanation of the components was very useful.

[paolo27th]

Really? I thought the piston burned fuel at every thrust but it actually does it only once every 3?

[pepene93]

@paolo27th youre thinking of a two stroke engine.

[karthiksk]

@paolo27th not once ever 3, once every 4. and hence the name 4 stroke engine.

A two stroke fires every 2 strokes.

[hammy1470]

Great video, but just so fucking wordy :L

[fairyheli2]

lift the lifters??? wtf is this guy talking about?

[MazdaArai]

otto cycle and rotary rocks!

[dwsnare]

Horses for courses, but we've always know the pivot or wrist pin as the "Gudgeon Pin", Piston arm ???, lol, yeah, i agree, its a "Con Rod". Dont know where the world get their phrases from, but its all a bit strange sometimes. I suppose we all just have a bit of a laugh & move on. Well illistrated though, thanks. P.S., can you show us how a piston ported two stroke works in comparison to a rotary valve & reed system please. ta

[BIZNAILEY]

piston arm? pivot bushing?

Connecting Rod, Wrist pin

[closthaman09]

hahahahaha i know huh? what when he ses "oil thrower" ??? lol

[JavelinMusic]

pls answer me, so how does the piston goes up at the compression stroke??? I only understand how the piston moves down because of the ignitino, but i really don't understand how the piston compresses air and gas mixture by itself!

[biohazard1243]

the momentum of the crankshaft moves it up just enough for the explosion happens again, so its always moving.

[wawworldatwar]

There is something that moves it up duh

[BIZNAILEY]

The momentum of the flywheel, is enough energy to compress the fluid. part of the energy comes from the spark plug, the compression isn't more powerful than the power stroke.

On multi cylinder engines the other pistons are always on a power stroke and it keeps the momentum going.

[david0aloha]

In addition, when you have multiple cylinders, they'll be offset such that when one is going through the compression stroke another will be going through ignition. In addition to the momentum that biohazard1243 mentioned, this helps make the engine's movement more fluid.

[david0aloha]

@33oj

Yah, that's what I was saying.

[triggerdance]

because the crank shaft is moving with such momentum that it keeps turning over

[1337Skizillz]

usually the way it goes up is from the motion of the other pistons going down, since all the pistons in an engine are connected to the same crankshaft.

[Circa1890]

You did good until near the end of your explanation. However to clarify, the inlet valve does not "suck air and gas into the combustion chamber" as you stated. Actually on the intake stroke as the piston moves downward a vacuum is created in the cylinder (combustion chamber). When the intake valve opens atmospheric pressure actually pushes the air and fuel mixture into the cylinder filling the void created by the vacuum until the pressure inside the cylinder is equal to atmospheric pressure.

[djayangel]

lol you are hilarious

[Bleezz]

this is true in many cases, however in this engine and other high RPM engines, its not uncommon to use a cam to control both the intake and exhaust valves

[spoonman73]

Is that why your car runs differently at higher altitude? Because of less atmospheric pressure?

[anuruddha777]

Absolutely Brilliant explanation...

Thnxxxxxxxxxxxxxxxx

[BlueDragon4484]

and the pistons penis XD

[angryace13]

some engines have more than two compretion ring, and more than one oil ring, tipically diesel engines.

[harpersteven]

all in all good video

[tailwheelflier]

ahhhhhhhhh,,the student has become the teacher.

[patterson9991]

the best way to put it is: SUCK QUISH BANG BLOW

[gabbaheyhey12]

whats quish? thats really clever, got any more?

[patterson9991]

sorry it was ment to be squish

[tommm3000]

You should learn the definition of the word "cycle". You are using it incorrectly. It's a 2 cycle motor, which is a 4 STROKE motor.

"Cycle" and "stroke" are not interchangeable.

[Zeyad0619]

thanks dude, my lecturer couldnt explain better than you, Many thanks
