How VTEC Works - A Simple Explanation

So new VTEC engines having vtec only on exhaust side explains there is no sound difference in intake just like the old VTEC engines right?

Yamaha adopted it or copied it and called it VVA..

Hmmm......a transmission in a camshaft. Of course!! Who whould have thunk? Yes, everyone😀

Where does "E" come into play?

vc ve q o video ta bom quando eu que nem falo ingles entendi como o VTEC funciona

Unless the engine is desmodromic, the cam-shaft does not close the valves; springs do.

So is the intake already higher? Is that why it doesn't have the vtec to switch between lower and higher?

Интересно как влияет эта система на расход топлива? У меня на Хонде ДВС К20 Втек с одной стороны. Много разговоров об экономии... Работая на бедной смеси ... Спасибо .

Champion!

תודה!

Why do you sound like Mark Rober?

This is how Honda rules the head game! 💪

Fascinating, the person or people who invented that are sitting on a beach with their toes in the sand, earning 20%😂

Was wondering if they could just have that more lift permanently on that exhaust flow since gasses coming out of them are already combusted and would not require more fuel?

And also other videos you make are excellent 👌. I watch and learn from you. Thank you

Your video, presentation, explanation is the best. Thank you Dear. Excellent ❤❤

Great video! Curious as to why not have vtec on the intake too even with a turbo? Just that little bit more opening to push the air in easier? So even when the turbo isn’t creating a ton of boost can still push air in with less pressure. Is it due to simplifying the engine for less moving parts or to minimize cost?

Hard to tell if this guy is 19 or 39😂

It was a fantastic explanation in just the right amount of time.

Honda (V-tec maker) was really genius

Am I the only one who thinks your voice is extremely similar to mark Roberts? Lmao

I wonder, for exhaust, why not always use the higher lobe? I do understand the explanation of using VTEC on the intake valves, but on exhaust you could always use a high lift right? It just doesn't make sense to not get rid of all exhaust gasses during low rpm.

Very helpful thanks 🙌

The Japans are geniuses.

Watching your videos on psychedelics are pretty awesome, so vibrant

Lovely explanation and an amazing engine . Tell me which oil is used to create pressure to lock the side cams against the rocker arms and wer does the oil pressure act onto .

Toyota has vvti

Great explanation. Thank you

damn so they have toggle cams 😭

I've watched a ton of VTEC explanations and this is the best one.

thanks, the explanation does help make it easier to understand

What Rpm does centre Cam start to work ?

Your videos are just excellent! Those Japanese sure know what they're doing when it comes to engines, don't they...

Quick correction, camshaft only opens the valves, what closes them are the springs.

Does vtec not affect the cams duration ? Would it be worthwhile to get a larger lift/larger duration cam on a vtec engine to make at least a little more power?

If the advantage of a low profile cam lobe is to increase air flow rate and increase mixture. But why doesn't the exhaust value always have the high profile cam lobe?

VTEC KICKED IN YOO

Literally a 30 second video on how this works... Circumlocution does not equal education.

I’m trying to learn from u most definitely I ain’t never understood something so fast

So from what I understand, vtec is like power band? Second question: vtec was on the exhaust side. How would the car perform if it had turbo and vtec on exhaust and intake?

I have never noticed any change on my Accord Vtec when accelerating. Is there an RPM area it should change lobes?

Ur awesome. Great explanation.

Thank you. Most educational, even though I'm not a Honda fan. That explains why Honda drivers are so cocky.

Vtec was developed in USA by Lycoming during WWII! Honda just copied it!

I have watched a number of your videos and my knowledge of cars are very basic at present, thank you for simplifying the explanation of how the vtec engine works.

The technology looks fairly simple, and efficient. My questions are that what are its disadvantages and why isn't it widespread in the automotive industry?

wow, that explanation with that animations made me understand this technology with click of a finger. thanks!

thanks
