Ken Shaw Toyota in Toronto presents: Know Your Toyota's Variable Valve Timing with Intelligence (VVT-i)
Пікірлер: 96
@CADable4 жыл бұрын
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.

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.

I’ve had my 2015 Toyota Corolla s for a couple years now and no engine problems whatsoever at 230,000km the dual VVT-I is as great as they make it sound my corolla having 132hp the power it creates around 4-5k RPM feels like a weak turbo like you can feel when it kicks in compared to no VVT-i

@FreeSalesTips3 жыл бұрын
@@CrisPBacon-zy6wh The answer is "computers do it". Toyota engineers figured out what valve timing is required for the different engine loads, engine speeds, and throttle positioning. This knowledge is mapped into the ECU. The specific details of advancing and retarding the engine events are a trade secret that won't be shared with the public.

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

You probably won't have to replace the timing chain (seriously. those things are beefy AF.) but the tensioner can loosen after a while, causing some noise.

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.
