This young people, is why you get an engineering degree. Very good video on the subject. Our VVti engine works very well as long as everything else is in order.
don't have even a mech engineering degree. however I've checked both this and the Honda vtec, the latter using an on-off crude system that only engages at x RPM. (6k?). The toyota is always changing depending on computer parameters! / Next is to understand why the locking pin is used.
Great video, this is incredibly helpful for my understanding of VVT solenoids. If I may ask, what was the motivation to make this video? It seems like it would take an extremely long time to put this together
With normal engines, the valve overlap is a compromise. They probably figured if there were some way to adjust the valve timing at certain speeds, they could decrease emissions AND increase power. It is not super complicated as far as how it works. What IS complicated is how they figured out the exact specifics like what speeds would be ideal to adjust the timing so much and how much oil should be fed to the advance/r3tard chambers. But that is why engineers get paid the big bucks.
If the inlet valves close late with the exhaust valve closed, the hot fumes go back to the inlet valves and return to the combustion chamber with oxygen plus carbon dioxide and some elements, this would not be as efficient on power as you may think because it is not exactly fully oxygen (it has been reused gases to burn again) and less cold air. This has put me off over the normal engine and I can blanked my own EGR it runs nice.
I had thought the same. How can i learn about more? It is like much more benefit for emission other than boosting engine power. But it is maybe about fluid mechanic also because not every rpm air intake be sucked into combustion chamber equally because of the property of fluid dynamic. So, if it is for adjusting and overcoming this situation then it can be really boost performance but i'm not quite sure. Some engineers should explain us.
Great VVT Explanation. I am learning that staff to fix P009 on my 1.4 TSI. Do I understand correctly that this is flexible setting process, so different time advance or retard settings could be applied to inlet camshaft in that way ? Or this is rather simpler process, so You can get only 3 seeings: normal potion, advance position or retard position?
Absolute best video on the subject. Others only explain it verbally, this animation helps WONDERS. Thank you!!
Glad it was helpful!
Glad it was helpful!
Да, это самое лучшее!!!!!👍
Amazing visual explanation. Works better than any other instructional!

By looking at these pictures, you can easily understand how the VVT system works. Thank you very much
Excelente vídeo. Gracias por tan magnífico trabajo didáctico. Toyotero desde Colombia

Excellent video and textual explanation! You rock!
Great video
Best vvt explanation
Excellent 👍
Nice vedio
Great animation ..but background music bad...
Great video. Thanks!
Excellent explanation
Nice explanation. Now I wonder how they got the idea to invent this cause its look complicated.

Do you have information - at what engine speed, how do the VVT phases work?
Thank you for this great animation
You're welcome
Great explaination thank you sir 🙏
Verry good vidéo
Thanks
What about high rpm. How does vvt help in that range of operation?
awesome animation. Seeing it in action.
nice VVT EXPLANATION
It would be nice if the song was more than the same 2 seconds on loop
nice background music...
Could be good to know what speed makes the computer engage VVT in each phase
i thought i knew how it worjs... YOU OPENED MY EYES
that beat really do being goin hard dough

Looshi cornere bookdum tima......😂😂BGM.
best technology than others
VV inlet T? Great stuff
how is the vvti hydraulic valve actuated? electronically by ecu or by pressure in combination with rpm?
Most likely it's electronic
Dangggg,its more complicated than vtec
Muito bom! Obrigado!!
❤
So what happened if vvt and vtec were combined?
vvt technology valve overlapping period more than normal engine speed ......reply me bro plzzz
yes
that music
Isme Combustion kaise kam jata hai. Thoda batao tho
لو تحطو موسيقى متل الموسيقى الراقيه في يوتيوب المساجات كان أفضل بكتير من هالموسيقى الصاخبة اللي بتوتر الأعصاب وشكرآآ لكم وهالمره مافي لايك
shukraan lak ealaa
Thanks to honda.
Always welcome
COOL!
Complicated engineering, needs new mechanic
GOOD
