What's the Difference Between 2-Stroke and 4-Stroke Engines?

- You probably have some knowledge of how internal combustion engines work. They involve pistons, Cams, explosions, etc. but do you know what the differences between 2-stroke and 4-stroke engines are?
The history of automotive and engine design has been marked by the existence of two main types of gasoline powered combustion engines: the 2-cycle and 4-cycle engine.
The name of each of these engine types suggests exactly how they operate. In order for any engine to complete combustion and thus drive their respective vehicles or machines, there needs to be combustion of the gas-air mixture and expulsion through the exhaust ports. The main differences in these two engine types is just how they approach this process.

you can tell the 4 stroke is really complicated when the complexity is not illustrated
ok
It’s really not at all lol
@@tylerdesautels1857it is a lot more complex than a 2 stroke
I feel it’s more simple it’s just intake, compression, power then exhaust. I’m confused about the 2 stoke
Fast forward to 1:15 to see a random shot of a mechanic checking a tie rod end on a Honda Civic …..
thanks man!
preciate it
awesome
in reality, 2-stroke produces more power. I have both 2 and 4-stroke bikes. Booth feels different. 2 stroke power feels direct and increasing in each rpm, the 4 stroke feels delayed even though produces more torque at lower end
Exactly. I was gonna say, he got that wrong. A 250 two stroke is a TON more power than a 250 4-stroke
4 stroke isnt really delayed, the power delivery is juwt alot smoother. But 4 stroke is a better design and power is delivered smooth, predictable and snappy at a wide rpm range.
2 stroke dirtbikes does have that rpm range where its "on the pipe tuning frequency" and power is absolutely savage. Thats ofc unmatched by a 4 stroke 😆 even a 250 on peak power band feels insane lol.
Personally, I like 4 stroke gas engines better than 2 stroke engines for giant scale rc planes I build and fly. But the 2 stroke gas engines are very popular given their price. 2 stroke gas engines are fine but don't sound as good in the air as the 4 stroke. And if you want even better sound, a 4 stroke radial engine sounds the best. The Moki 250cc for rc planes is a 5 cyl 4 stroke radial engine throwing a 30 inch propeller and sounds stunning, just TH-cam search it. They even make them up to 400cc. Yes, RC plane engines lol.
I rlly needed this getting my first bike soon
2 stroke engines usually also lose power way more quickly. In kart racing it's not uncommon to use multiple 2 strokes in one race season. Whereas a 4 stroke will last multiple seasons. But that sound of a 2 stroke is unbeatable.
4 stroke on paper is a better engine overall but nothing will beat the fun factor of a 2 smoker’s power band
First ad I've watched completely
Good to hear! We advertise to grow our channel, so we’re glad you enjoyed!
Concerning Reality I'm like I know everything about 4-stroke engine but about 2-stroke and after 10 Min I get this actually video not an ad I will definitely be checking out this Chanel
Thank you😊
Thank u !
It takes
Ever heard of Ship?
Massive ships have 2-stroke Engine, because of the high power they produce.
Very Excellent sir 👍👍👍

I like this video,i can easily understand more
my pleasure
The two stroke engine, If the fuel intake happens at the same time as the combustion, would it make the engine have a bigger prone to igniting the fuel intake and the gas tank?
Fuel intake happens after combustion, after exhaust. They are separated while exhaust is pushed out the port hole, causing a vacuum effect that pulls fresh fuel air mixture in ready to ignite again.
Still got this 21 years old Yamaha's RX 135
2 stroke racing bike left the group
No its just laughing hardly at the corner
You showed the legendary Mustang from the late 60s and early 70s when you were saying that there were cars made with 2 stroke engines...
Heavy duty are in the same class please
best video
Tyrone the “mechanic”
Uhhh… I thought the 2nd rotation of the 4 stroke cam shaft came from the power stroke of the opposing piston…
….and not two rotations from one power stroke, as the video says
Anyone?
For anyone about to rant, two strokes can produce more torque, as a result of combustion frequency, but, that does not make it more efficient, it wastes a lot of fuel doing so. So to anyone wanting to compare modern efi 2t race bike engines to this efficiency equation, keep in mind that they use pistons instead of gas... You'll do the top end on one of those in say, 15 hours of runtime, compared to 1500 hours on a 4t. But they are fun though...
Also, a modern four banger isn't as weak in the power figures as you'd expect, horsepower means nothing, torque is everything, and when it comes to consistent delivery of said torque, 4t wins everytime. Unless you are very skilled at keeping your 2t in it's powerband. And there are people that can. Then obviously it wins out in pure torque.
Thank you my boyfriend is big on this stuff and that helped a lot
i aint no genius but i know that you have no idea what u are saying
@@s4rg380 you are absolutely clueless
@@s4rg380 it's almost if this guy knew that Horsepower = RPM x Torque over 5252 his whole paragraph would seem dumb
What's up with the dislikes?
😤😤😤
Don’t know! We’ve been promoting this video a little, so they might be coming from there. Not sure. I don’t think there’s anything wrong with the video 😊

Lol
Is it Chris griffin?
Due to first seconds , thought the explanation of strokes gonna go a bit another way.
Let's just say, It's an efficient steam engine ;l , time for change I think 🤔
i love you
Jumallauta "small watercraft nad gardening equipment" how about the greatest invention of all time the suzuki pv and other great mopeds??
Enter the rotary
only issue i have is the claim 4 stroke is more powerful than 2 stroke, that is not the case 2 stoke produces more power due to the rapid combustion cycles, everytime that piston comes up its compressing and combustion happens, 4 stroke takes twice as long to have the combustion cycle occur given both are running at the same rpm. my 200cc 2 stroke will take my friends 400cc built 4 stroke from the dig all the way to the 200ccs max speed after that the 400s gearing and top end takes over, both are fast 2 strokes just get to the top end faster but are limited due to gearing, and the efficiency of the combustion cycles
How do you tell if it's a 2 or 4 stroke just by looking at it?
The exhaust
@@brandontaylor-usedon3114 what in exhaust?🤔
@@gokukn2336 the shape of the exhaust
Exhaust lol😂
Wait, I came here for the difference between 2stroke and 4stroke weed eaters… I was not expecting cars and carts
The voice in this video is agonising
I miss two strokes.
One goes Ning Ning one goes vroom vroom
2 strokes has more power than 4 strokes as there's a power stroke more often than 4 strokes so what that man said is waffle 3:43
2:05 actually, the widespread use of the four stroke has *everything to do with governments sticking their collective nose in private industry* to quite literally force the two-stroke out of market for street legal applications, instead of allowing ‘Supply & Demand’ i.e. Capitalism” to play out in a free market. (Ya know, like how we are all made to believe from Birth that the USA is a ‘Capitalist’ country m, when this just one more example of how that is one of the biggest myths in the world.)
capitalism is not per se coupled with a free economy, do yourself a favor and dont get them mixed up. Also, i suppose by deeming the usa not "capitalist", im assuming you are pointing towards it being a socialist economy? A phrase that anyone having the most elementary knowledge surrounding those two terms would find funny to say the least. anyway i dont mean to disrespect cheers
This guys voice makes me want to die
Lol!

no u dont
Dude get a mic shield... all I can hear is pppt pppt pppt every time you slam your breath on it.
2-strokes are more efficient and more powerful
