Toyota VVT-iE, Variable Valve Timing

Describes the operation of the Toyota VVT-iE or variable valve timing with Intelligence Electronic. This is Toyota's highest state of the art variable valve timing system, which uses a small electric motor/actuator to advance or retard the valve timing. By varying the speed of the motor, the system is able to change follow the CAM sprocket, increase speed to advance or decrease speed to retard. The end result is a fast acting and accurate CAM timing control system. See how it works and why.

Its not better than vtec,just more officient,but the power and mpg gane doesnt worth it..

there are some better systems on the market,or just lighter cars..

@StefSyros I think you've just touched on a key point: Lighter Cars.... That is the essence of raising fuel economy in the future. Using lighter materials and advancing the technology. Thanks so much for posting.

i got a question the vvti ingrease horsepower or spend less gas

[ADPTraining]

@ErikAyJosE1 The VVTi changes the power curve of the gasoline engine. All gas engines operate at an optimum RPM only. It is the nature of gas engines. The VVTi shifts the optimum power curve for better gas mileage and power. Thanks for posting...

good system

but why he says "timing" in conceit way

[manlymud]

@ErikAyJosE1 the thing saves you gas when not active, when you mash the gas the thing takes more gas but way more horsepower. so around 5000rpm the thing says its time to haul ass

@giova2k6 thats exactly what i was gona say! Surely its maybe easier/cheaper to manufacture and install, but with no real benefit to performance over the conventional system. Weird

@giova2k6 I think u r right

[giova2k6]

Compared with the VVT-I, how different is the VVT-Ie? I mean, here you have the electric motor to do what in the VVT-I is done by the oil pressure, so it seems easier to fit a VVT-Ie system to a non-VVT-i engine compared to the VVT-I; you don't have to drill oil passages in the head, but you just have to modify the timing sprocket and the camshaft so that you can fit the electric engine on the camshaft, then you have to program the ECU to manage the system, right?

@Waizu91 Um not really...

[luckymisselala]

more shit to brake

[Waizu91]

So its basicallly like vtec just 10x better haha
