This explanation makes sense but in my opinion it's always best to test ride different vehicles to understand which engine actually suits your needs. For example when xplulse 4v was launched we all expected better top end performance than the 2v version but the difference was very marginal and similarly people complained about 2 valve setup in pulsar f250 but the bike is delivering good enough top end performance. All we can learn from this is that bikes perform very different in real world compared to the spec sheet
Thank you bro. I UNDERSTAND today. 2 Valves motorcycles performs well even in low REVVS . eg. FZ25. 4 Valves motorcycles performs well in TOP END with High REVVS. eg. Duke 250 😊 🙏🏻
Tum khatarnaak ho 😀 bhai. Engineering College mein agar tum lecturer hue toh 4 saal ki padhai 1 hi saal mein khatam kar doge 😂 wo bhi har students distinction ke saath paas hoga 🙏👌👌👍😃
Umar bahut kam hai apki lekin knowledge ke bare mai top level engineer ho Bhai aap .thank you for this video .future mai bahut aage jaoge , uparwale se prathna hai meri .jay hind.
Good detailed concept clear vdo. Itne se chote engine mein 4V aur 2 sparkplug ho to high rpm per power, performance accha toh milta hai lekin mileage accha nahi milta aur engine chota hone ke wajah se itna bhari combustion engine zyada saal zhel nahi sakta. Aise 4V engine compared to 2V jaldi down ho jaate hai, piston, bore, valve kharab ho jaate hai aur engine performance bilkul kharab ho jaati hai. Upto to 150-250 cc mein 2V technology hi acchi hai. Bajaj ki bike DOHC technology ki wajah se 5-6 saal mein kharab ho jaati wohi other company ki bikes min.10 yrs acchi performance deti hai. Yehi baat hai jo Bajaj return back to 2V in low powerd CC engine.😊
bhai mein iti mechanic diesel kar raha hu iss saal ..aap koi dusra channel ho toh waha aapp techinal explaination kya kijiye..aapka explanation bohut accha hai .
Very helpful explanation. I have used LML adreno some 20 years ago. It had 3 valves. Don't know how that was working. But that bike was full of technology flaws.
Bajaj gave 4 valves in their lower capacity engines like discover 100t 125st 150s pulsar 135 and then discontinued all models and returned to 2 valve engines in bs4 models . Only higher capacity engines like ns200 and ns160 are decently successful. Yamaha and honda also use 4 valves in high performance bikes like cbr 150 and r15 but not in fz or hornet suzuki also use 4 valves in 250 cc engines and not in 150 cc.
Yes, you are right.

@@vishwastoraskar this is myth ki 4v engine jldi khtm ho jata ha 2v engine se 😒 higher rpm me chaloge toh bike smooth chlegi 4v engine se power acha milega agr 2v engine high rpm me chlega toh usi me prblm aayigi bro 4v engine is far better than 2v engine as compared to power or as compared to life 😒
Lot's of thnx for an another informative video. My request to you in future create a New video details about 2 valves and 4 valves with SOHC and DOHC engine
You can make a better engine with 2 valve itself,if you can somehow change valve surface area with rpm,valve frequency,position with rpm. You can use solenoids in the camshafts to vary these,a microcontroller will sense the rpm and will send a pulse to relay to create magnetic field in the solenoid to push or pull the camshaft adjusting the valve configuration hence Your torque curve will skyrocket even at high rpm. (:
@@adrenalinerush11 i wasn't talking about "just" variable valve actuation..! There are multiple ways to implement valve position and timing controls. If you want to learn,i guess try studying few patents or research journals,rather than watching TH-cam videos
The more moving parts you have the more chances of fault. 2 valve air cooled, kickstart equipped bikes are the best in reliability and cost of maintenance.
Books padhne k bad jub upka vedio dekhta hoon to concept pura clear ho jata hain vai..... 💕

Achhi baat ko achhi kahna, achhi baat hoti hai.
Very impressive ! I get to see, only a few like you could lecture / review on Auto-Tech like a free-flow without any interruption. Bravo!
I hv India's first 4 valve bike. Pulsar 135 ls, . 13 years ho gaye .. still giving best performance.. 67 kmpl.
For Best Example i would say Bajaj's N250 (2 Valve) & NS200 (4 Valve). N250 Loaded with Awesome Torque and NS200 loaded with Power.
Addicted to your explanations...🥰
Yes
Absolutely right ❤️👌👌👌
Very well Said
Thanks sir for giving me a heart it just make my day 👍
Yah
I’m mechanical engineer by profession so I can say his knowledge is very point to point ❤

You are really awesome in translating technical concepts in to non technical ones which even a layman can understand.
Extreme 160r stealth edition ka detailed review kb kr rhe ho love from MP28
After watching your videos on cooling system, 4 valves and SOHC vs DOHC, I am feeling Pulsar NS200 is value for money.
The most underrated channel😕

Bohot hi informative video hai ❤️ from Kolkata 🛵🛵🛵🙏🙏🙏
Also 4 valve engine produce more heat than 2 valve , thats the reason most of the 4 valves are liquid cooled where as 2v engine are air cooled
No one gives detailed review like you
These information series is my favourite
Hash to....
Mujhe ye pahle se pta tha..
As Automobile Engineer😂😂😂😂
And I liked your information
Bahot Achha Samjhaayaa Bhai. I Drive Apache 4 Valve Once And Its Good At Pickup And Top Speed. 😍 🏍️
finnally i have cleared my doubt about the advantages of 2v and 4v
A long awaited video
Ur explaination is too good 👍👍👍
Aapne bahot hi simple language me samjhaya sir👍
Tumara stlye accha hai Bhai 😊 jordar👍
Bahut achchhi malumat hai bhai
aap k yee vdo alag level k hote haii....
tnx vaii...

Thanks bro for information 🙏
Nice Explanation 👌 . Take Love From Bangladesh ❤🇧🇩
Me ek mechanic hu......ye banda bht talented hain🤘👌👌
That's why I chose FZ25 over RTR 200 as per my need... Good Video 👍🏻🔥
Fz25 how much valve?
Now we have free valve technology by Koenigsegg. Where valves don't operate on cam shaft. Operated by electronic soleniod actuators
Love you bruh musth samjhaya ❤❤
Mashallah RAYYAN bhai bohot sahi samjhaya aapko bohot sahi straight knowledge hai say alhamdulillah 🙂❤
Can you make a video on 2-stroke & 4-stroke engines... Need to know the differences between them
Sure
pata nahi jab bhi camshaft ka naam sunta hu mujhe megan fox ki yaad aa jaati hai anyway nice explanation
Brilliant video in layman's language...keep it up
बहुत शानदार वीडियो है भाई
Thanks bro, very helpful and informative
Jazakallah khair for the easy to understand explanation. Love your videos.

Learnt a lot brother! You explain so well bro
Example:-
2 valve :- Harley Davidson x440
4 valve :- Triump speed 400.
Ironically harley is expensive.
