How Two Stroke Engine Works

[@T34theAmericanheavy]

A stroke is when the piston moves from tdc (top dead center) to bdc (bottom dead center) or from bdc to tdc. 4 stroke engine has 4 strokes. Intake(tdc to bdc), compression(bdc to tdc), power(tdc to bdc), exhaust(bdc to tdc). As said in the video a 2 stroke is this process but cutting the number of stokes in half by combining the intake and compression stroke together and then combining the power and exhaust stroke together. Im just clarifying some of the details not criticizing the video as I find it very informative.

lovely comment my guy

[@hinesd1960y]

Thanks for clarifying. I was confused until i read this comment. It clicked for me and made a lot of sense. Thank you!

[@statbuckscakepop7229]

Perfect

[@justinblake420]

Yes was actually a good video

[@christianvlek]

I'm 36 years old and have worked on cars and bikes and had dozens of two strokes since childhood , and I've NEVER understood how a two stroke engine worked until now. makes perfect sense now , thanks for the upload .

[@vortexride1475]

+christian vlek thanx alot man.... i am glad that i helped someone....😊😊

[@TheRepairSpecialist]

The awesome two stroke in all its glory. The power uptake on these things are amazing. I love how they sound, how they run and how they are put together. That's probably why I have been bisecting and examining them for the last 25 years. Thanks for sharing this video! Craig

[@vortexride1475]

Welcome bro...

[@dimjim2365]

The cut away is awesome, really helps, Thanks

[@Blowinshiddup]

I'm 50 yrs old and honestly never thought to ask how they work. Since I bought an old Skidoo Elan I figured better late than never. Thanks

[@jackglossop4859]

My man: with your second language English you gave me a better understanding than some of the videos made by first language English. Respect to you Sir! 👏🏻👏🏻👏🏻👏🏻

[@patricktatten]

this is such a great video! I'm studying for my EETC certification test, and this is AWESOME supplemental material. Thank you!!!

[@blipco5]

Great, clear explanation. 👍 It has always surprised me that two strokes even run.

[@6900pilot]

Very well explained thank you.. Does the fresh air fuel mixture lubricate the crankcase bearings in the process?

[@LyleJohnson-q4l]

Very good explanation. Never really understood how it worked

[@terrywalley8313]

Best explanation for 2 stroke, I have heard to date. Thank you

[@ZawroJR]

the best explenation on youtube for a 2 stroke

[@vortexride1475]

Thankyou brother...

[@syedmuzamil2044]

It's really nice mr shahjahan akram to see you here, i was looking for to understand 2stroke engine suddenly i found yours....I wish you best of luck. DAE_Mech 22

[@redphantom70]

Your cutaway motor is a very good example of the two stroke. You explained it very well. Good video.

[@spelunkerd]

The big problem with two stroke engines is the way lubricant oil is mixed with fuel, so the carburetors are tuned to avoid damaging lean mixtures where oil concentration is dangerously low. To avoid that lean state the carburetors are tuned to run a little on the rich side. When that tuning slides back to stoichiometric values the idle rpm increases which causes even more cylinder wear. Emissions regulators get their panties in a knot when they learn that mechanics are trained to tune machines a little rich on purpose to make equipment last as long as possible.

[@kaisern6032]

Thank you for a straight forward and clear explanation I'm sure you earned several subscribers for this one lol

[@TomBartram-b1c]

Really interesting. Please explain why some 2t engines have a REED valve even though the piston covers the inlet port preventing blow-back?

[@THESLlCK]

This video was FANTASTIC

[@DobleWhiteAndStabley]

Thank you for making this.

[@israelrivera835]

Great job, I as a lay man on mechanics..I understood your presentation, thanks!

[@PauloConstantino167]

Engines are such beautiful human inventions.

[@fredpresler]

This is a great basic engineering talk for us idiots that need it broken down. Thank you.

[@ThomperBeThompin]

Great video, thank you!

[@darylAdrian]

Easy to understand, nice sharing 👍

[@faezothman1592]

Very useful. Thank you 😄

[@cwbaldwin61]

Very simple and straightforward. Nice job.

[@Raulley27]

Best explanation ever. Congrats 👏👏

[@derykma1]

Where is the air from the carburetor?

[@aurangzebahsan1]

Best video. More precise and clear. Good job brother. Thanks alot

[@vortexride1475]

Thanx alot brother....

[@randomstuff8286]

I watched so many videos but I was not so cleared.but you just nailed it never ever going to forget about this engine and the sad truth is it's going to bang

[@divine_swine9665]

your demonstration and explanation is really good. I’m a bigger fan of the 4 stroke engine tho.

[@YOGESHYADAV-re3yv]

In the 2 stroke engine due to the presence of the lubrication oil, some of the lubrication oil must be combusted during the time of heat addition. Hence there is more friction and loss of work in 2 Engine. So Hence 4 stroke engine is more efficient and have more power .

[@hurricanetortilla-91]

Thank you for this, you explained it very well

[@harshith4484]

Sir ,if we pass air-fuel mixture through crankcase ,then how will you lubricate the crankshaft!...???

[@vortexride1475]

The mobile oil that we add in fuel tank... works as lube for crankshaft bearings...

[@dereksmith4178]

Thank you nice instructions

[@m.a.p.4hp737]

Loved the video brother. Thanks for making it.

[@irvb9881]

Great explanation, thank you 👍🏻

[@damo690]

Thank you. This was very helpful

[@rakeshkarmakar102]

Thanks you for making this concept so clear to me

[@Tensho_C]

how do people come up with this stuff. really cool

[@brandfordhowell6960]

Thanks for the demo

[@kejtov]

What engine model is that? It looks awesome

[@vortexride1475]

Bro this is 2 stroke engine model...

[@bryville1769]

Really really good video.

[@Yash-fg5cy]

Very nice explanation. Thank you very much

[@vortexride1475]

Welcome brother....

[@shacharshipony7525]

Great video!! Thank you

[@victormaxwellpeters9771]

After explosion stroke the air inside will still hot enough to create pressure. Is there a chance of pressure being balanced between this hot air and in coming fuel air mixture there by resuming engines function???

[@vortexride1475]

For this reason the exhaust port is slightly higher than intake port...... i.e exhaust port open before intake port... so the high pressure gases flows out to exhaust... therefore no restriction is left in cylinder to disturb intake air fuel mixture...

[@Tensho_C]

how do you make sure that all the exhaust is replaced by air fuel mixture? or is it a ratio?

[@agri-6239]

Verry clear explanation 😍

[@Lucentlens]

Brilliant explanation bro' - one of the best I've seen.

[@multa765]

Now I understand, I wasn't sure before. Thank you.

[@talsakivibez4891]

Thanks for the video bro 🙏🏽

[@hindutva2685]

Very Nice explanation sir 👍

[@davidsiilva]

thank very much for the lesson

[@MrHdearal]

Excellent explanation!! Thank you so much!!!

[@lesterjames4093]

Good day. Nice video. I have a Yamaha dt 200r dirt bike. I would like your advice on something. I am seeing a lot of two stroke oil settling under my piston causing my engine to stalled.

[@vortexride1475]

Well i am currently working on my YB 100 yamaha.... also 2 stroke engine..... it has same issue..... when ill find solution.... i will share with you guys....thanx...🖒

[@jxbusic]

Thanks. Very useful and well explained.

[@joshuadixon7395]

Well, that video answered my question. Thanks man!

[@vortexride1475]

Welcome man....

[@demounit2505]

The ports and their positions in the cylinder replace the valves and cam shafts in a four stroke.

[@MRptwrench]

Thank you! Very good explanation. Granted, I faced somewhat of a language barrier due to my familiarity only with my local dialect, but my understanding of 4 stroke operation helped me overcome that. I wanted a visual aid and was hoping for an animation, but the cutaway engine was much better! I needed this video so that I could work with my son on our 2-stroke 46cc engine. So thanks again for simplifying that! Now our next challenge will be a reeded 2-stroke!

[@willardleap1289]

Great video

[@creativeboy351]

Genious fella

[@johnguilbert1349]

Great video! Thanks for the demonstration!

[@tracewallace23]

wouldn't it work a little better with the exhaust port slightly higher there by creating a vacuum to draw the fuel air mixture more efficiently? great video though ☺️

[@vortexride1475]

+Trace 23 thanx mate.... yes could be better... but we have to keep in mind several other factors also...😊

[@dipjyotidoloi9348]

Excellent..... brilliant

[@saradhipapisetti1265]

Good knowledge thanks

[@leadsmith5873]

Excellent!

[@mysarababekir569]

Very nice

[@ZmannR2]

What I don’t understand is in racing motors such as a motocross bike, there are reed valves that spray the mixture but once it sits in the crank, how is it a mixture still?? Also the power valve is another mystery to me as to how it operates. Basic 2 strokes don’t have power valves.

[@harshithvarma6583]

awesome explanation bro you made it more detailed by explaining with the engine.thanks a lot bro.

[@shfxls]

Good explanation! Thank you!

[@tommy3182]

Very helpful. Cheers 👍🏻

[@brorheyduhig]

Thats why 2 stroke with smell when smoke out to pipes because the mixture is not totally dispose unlik valve (intake,ex) 4 stroke

[@farrukhakhter8792]

Excellent, Plz info me the actual fuel average of Yamaha ybr 125 g and parts are too much costly as compare to other bikes 125 brands ?

[@vortexride1475]

Now the parts are easily available... and follow me and text me on facebook page... i will give you complete info☺☺

[@josephmiddleton8754]

great video mate very helpful.

[@vortexride1475]

Thanx dude

[@GixxerRider1991]

Great video!

[@wes595]

wes595 Hello, and thank you for this video! My question is in regard to the exhaust and use of the expansion chamber and power band. How does the expansion chamber help the engine performance? What happens if you reduce the size and change shape of the expansion chamber in the exhaust? I recently changed the geometry on a 1100cc 3 cylinder two stroke exhaust to fit in a smaller jet ski, but now since I changed the shape and volume of the expansion chamber, my powerband is not as powerful. Will this cause premature engine wear? Thanks in advance!

[@vortexride1475]

Really sorry dude.... I have never worked on expansion chamber.....

[@Leopard69]

Thanks I Learned something

Thanx bro....

[@sankarisubramanian5549]

Plzz do a video for three stroke engine

[@North700]

Great explanation

[@dillonbrewer862]

This is partly wrong, the exhaust port opens a little bit before the gas port so the exhaust can leave without the gas leaving to. Then it opens the gas port

[@vortexride1475]

Hmm... that is true..

[@mxatrider5705]

Not on this engine look at the top of the piston its makeing the gas/mix flow up the bore instead of just being sucked in . On a dome or flat top piston engine the ports would be as you sed .

[@charliethiede3992]

Dillon Brewer another reason why these engines aren’t usually used on modern vehicles is because of the emissions. The emissions are burning oil, and a little bit of gas and oil are being released because the exhaust and intake are open at the same time.

[@claybornlewis276]

you are absolutely right I was thinking the same thing when I saw the illustration they are straight across from one another and that is not how it works

[@delusional_optimist]

such a good explanation thanks so much
