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 🙏👌👌👍😃
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 😊 🙏🏻
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
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.
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 .
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.😊
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.
Front chain sprocket jo shaft se juda hota hai usme kya thoda age piche move hota hai. Kaal mai chain sprocket clean kar raha tha tab notice kiya jab 1st gear me front sprocket ghum raha tha tab wo thoda age piche ho raha tha. Please sir ans dijiye.
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. 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.

Bro how vva can be actuated with sohc?, Like with single camshaft how can the machine manage 4 valves in a variable play. Pleaee let me know. You can consider MT15 as an example as it comes with 4 stroke 4 valve and sohc engine which also supports VVA
Can you tell me why engine sound changed for pulser after arrival of NS 200 and in Apache after arrival of RTR 200 4v?? I loved old sounds of Pulser and Apache during 2010s, new bikes sound screaming lacks bass. Can someone explain why?
Yaar mileage toh engine size aur ecm programming pe depend karega na? It's just a coincidence that 2 valve engines are also small commuter engines which gives them a higher mileage?🤔
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.
Jaisa apne bola k 4 valve ma Spark plug center ma hota hain....but yamaha R15 v3 to 4 valve engine hain to usmain Spark plug to side main hain because o SOHC engine hai or vva vi hain usmain...to kaya o thik thak hain.... Ek CBR 150r tha jo 150cc segment ma DOHC tha but vva nahi tha usmain or o to nahi raha ...or duke 125 ma DOHC to hain but cc mt sa a66a nahi hain please answer me this question.... because I bought yamaha mt 15... please tell me... kya yamaha mt15 engine better Hain or DOHC sa R15 v3 ka engine me milage vi A66A Hain ..even Bajaj dominar 400 main triple Spark plug Hain !
Kindly reply, I have an opportunity to choose between 2valve, X plus (at reasonable price) and 4 valve X plus, I am a city commuter, which motorbike should I choose, I am not a tech. Freek, only want a less maintenance one.

Bajaj bike fake in speedometer
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...🥰

Apache rtr 160 2v me itna jada viberation kyu hai
Thank you so much 😊
Itna accha se samjhane ke liye
Mai Mechanical engineering 5th sem ka student hun
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
Tumara stlye accha hai Bhai 😊 jordar👍
Can you make a video on 2-stroke & 4-stroke engines... Need to know the differences between them
