Know Your Toyota Mechanical: Variable Valve Timing with Intelligence (VVT-i)

Ken Shaw Toyota in Toronto presents: Know Your Toyota's Variable Valve Timing with Intelligence (VVT-i)

[CADable]

VVT - i system (Variable Valve Timing intelligent) use a computer to optimally control the opening and closing timing of the intake valve in accordance with engine conditions.
This system uses hydraulic pressure to vary the opening and closing timing of the intake valve, resulting in improved intake efficiency, torque, power output, fuel economy, and cleaner exhaust gases.

It was clearly and clean explanation on vvti thanks

[davoinshowerhandle]

Please Tell me your not just reading this on a paper while recording.

[mfst]

So, when to exchange the timing chain?

I have a prolem with my manual previa 2000 vvy 2, 4 gasoline. In second gear give pulls and pulls and I have to increase the gas to stop doing, if not the car shakes like it is in wrong gear...please help

[JosephMile]

Just general terms... learned nothing.

[petermuniz]

I got a new car a 2020 Corolla dose it have vvti

[mrflamewars]

Better than Under-Engineered American Rubbish, i.e. the Ford 5.4 where you have to permanently disable the cam phasers to get the rattle to stop

[technomage]

That's great and all, but my question is: How likely are these to have problems, and how hard are they to diagnose and fix?

[jonathanmachado]

Nice video. Question: a toyota engine 4.7 vs the same engine with vvti (lexus gx470 2004 vs 2006) were the VVTi makes diffrence? At low rpm or at high rpm? I think at very high rpm tge vvti change the timing specs to deliver more HP and torque so under 3500rpm are similar. What do you think? TKS

[antoniosilveira]

Think that’s basically what the almost gone distributor use to do, advance timing on acceleration

[brettpitman]

How much to put a turbo on it u reckon

[truthseeker]

Helps start up...what about later down the road, where the actuator starts to make noise on cold starts?... Is that the improved start-ability? Being on lower-high (123460) mileage Toyota. I think this is bs. Mine started at 100k.

Its more like advertising than educational

Уважаемый тойота!Крнечно то что вы сделали это канечно хорошо, но вот что я сделал. Дело в том что я разработал новый двс с кпд до 75% который до сих пор не мог изготовить не одна автомобильная компания.К вам у меня предложение - я хочу чтоб вы показали об этом на своем канале.Конечно я не могу расскрыт секретную часть его изготовления но то что не явлется секретом я с вами могу поделиться.Все описание я могу вам отправить по почте след письмом.

Don't you engineers think of anything besides benefits? Timing belt slips enough or chain jumps. Valve timing kicks in throwing off the ignition, things become too out of whack and BAM, engine parts, coolant, and oil all over the road.

[jurajokasa]

Thats why they can make 53kw with just naturally asporated 3 cylinder 1 liter engines ....Skoda and others cant make past 40kw without forced induction

[Motorsportsgeek]

They make these damn vvti sprockets in mexico and they fail, i just replaced an exhaust vvt on a 2010 rav4, luckily I did my labor so parts were only 400 with all the gaskets, dealer wanted 1500 estimated minimum because my car was out of warranty.

This technology makes sure you have to remove throttlebody and idle air control valve for every six months and clean them cuz this allow exhaust gas to your intake.
