I'm an electrical engineer after a veering away from mechanical engineering freshman year of college. It constantly amazes me how mech engineers develop very intricate control loops with machined aluminum parts that mimic control loops on my circuit boards. The VVT system described in this video is a mechanical work of art, especially the phaser. A while back I replaced the VVT control valve on my Prius and wondered how an simple external part wears out sooner than the intricate spinning cam phaser. I think the reason is that the control valve's electromagnet is feeble and has no spare thrust to overcome carbon deposits. A cam phaser has 80 psi of oil pressure behind it to accomplish its job. Like other posters to this forum, I agree that the video underscores the importance of clean engine oil.

Very interesting. I own a Focus MK 2 with the 115 HP 1.6L Ti-VCT engine. The engine has a rather poor reputation being often cited to be a "hybrid" between the regular 1.8L 125 HP engine and the 100 HP 1.6L 100 HP engine.... as in having the performance of the 1.6L 100 HP engine but the fuel consumption of the 1.8L. It certainly feels too thirsty for its felt power output. There is also the issue of reliability and justification for such a complex technology in an engine that by all means and accounts is little more than a crappy 1.6L standard naturally aspirated engine. What I mean to say is.... you can have basically the same power output and fuel consumption with a regular 1.6L engine.... except those dont have 4 rather expensive variable cam timers that add another point of failure. Yes, it doesnt have an EGR valve because it does this via cam timing... but then EGR isnt such a common failure on gasoline engines but more on diesels - at least to my knowledge. Overall, there imho just isnt enough justification in terms of performance and fuel consumption gains compared to increased repair risk and cost. Not to mention the need to be more conscientious about oil changes with it which is another nail into the cost benefits of it. Most gasoline cars in europe are primarly used as short to mid range city vehicles as regular long range drivers lean towards diesels. I mean before VW decided to cheat. So you have a car with high fuel consumption and low power.... it at least should be cheap in maintenance and survive rough treatment because in terms of economics... it simple isnt worth gentle maintenance, it only has to live long enough to outlast the rust. There is an filter mesh before the VCT units oil supply that is meant to protect the VCT unit from debris in the oil - a good idea in principle but the original mesh/oil supply diameter was pretty small and as such if you are unlucky, it gets clogged completly and starves the VCT unit in question of oil with predictable results. Later models have increased the oil pipes diameter and also switched to a better oil, for the most part increasing reliability to acceptable levels. Still a lot of technology for very little direct visible driver/owner gain. On the bright side, on more modern turbocharged direct injected engines like the Ecoboost - it probably can achieve higher gains and also due to higher overall performance and actually visible fuel consumption gains, can there also justify increased maintenance costs. The 1.0 L 3 Cylinder ecoboost is quite a fascinating engine, using a watercooled exhaust manifold to reduce or even avoid the need to enrich the fuel mixture to protect the turbo/catalytic converter from high sustained engine loads exhaust temperatures.

Your automotive channel has some of the best videos on KZitem. First off, the camshafts in this video are hideous. Please tell me they were pulled from the bone yard. It seems to me the cam phasers are either "off" or "on" triggered by the ECU. The duration of the lift does not change, it is only when the valves start to open relative to the pistons. Is this correct?

I’ve desperately been looking for an answer to this question: 2GR-FE Toyota engine (3.5L v6) makes a clicking sound whenever I give it decent throttle. After I let off the gas, it clicks again and is loud enough to hear while driving low speeds. Could this sound be explained by the valve timing controller moving between advance and retard? When you demonstrate it at 4:45, there’s a decently loud clicking, quite similar to what I’m hearing. Also, could this be cause for concern? I don’t think it’s normal to hear this, or maybe I just never paid attention.

What a great review. It seems this system as shown does not allow a change in the duration of valve opening, which is dependent on the shape of the cam lobe. So, when you open a valve early it must close early. I was a little confused when you said that pumping losses are reduced both when you close the intake early and when you close the intake late. Presumably this depends on intake pressure, turbo effects, etc. It would be interesting to see a practical summary of how the PCM behaves in different situations, WOT, cold start, coasting on the highway, etc. There is enough detail there for a whole extra video....

My 2015 Hyundai sonata is currently using ecvvt meaning the intake valve is controlled electronically via motorized cam phaser mounted on the camshaft to allow the ECU to advance or re t a rd. Well guess what? Those phasers are known to fail, noted in so many customers complaints. And unlike the regular intake valve solenoid that could easily be replaced in 5 minutes with a $30 part, the electronic intake valve timing is a pain in the butt to replace and a $2000, $3000 $4000 dollar job since the timing case would have to be taken apart to get to the cam phaser.

OK, so what are the odds of this being the one second rattle on a cold start up what most people think is the timing chain tensioner going bad or a stretched out timing chain, my timing reads a steady 15° at idle warmed up, so I’m assuming my timing chain is not stretched, that one second rattle, if I let the car sit for a couple hours after running, the tensioner holds pressure for a good couple hours before it will have that rattle again, then disappears immediately, and engine is quiet, as can be 160k miles, burns no oil in between 3000 mile OCI’s 2006 VQ35DE eng. (G35 coupe) Also, the cover on the timing chain cover right in front of assuming that actuator is that a service hole for that issue cannot be fixed without pulling the timing cover?

soeedkar99, A great and thorough explanation! As you speak clearly and without hesitation, I am curious, do you work in the industry in automotive engineering? I do have a question that has been bugging me for ages. I get the feeling that a more viscous oil, and therefore higher oil pressure, causes the intake cam on VVTi engine to retard more than would be optimal. And this "Loss of low end torque effect" seems to be more directed at a cam timing issue than just the more viscous oil causing loss of low end torque through windage and shearing/ friction losses. This seesm to occure when using a Xw30 grade oil in the Summer instead of the recommended Xw20. Now, I also do "feel" more power at high rpm with this thicker oil as the same time as ther was low end torque loss. Curious on you thoughts. This all assumes you would variably and continuously retard the intake through 15 or 20 degrees with hydraulic pressure as rpm rises in a ECU "power demand" scenario. Am I off base here? - Thank You again - Sandy

The peaces that you show in 3:30 are also there to seal the chambers and prevent oil to leak from one chamber to another :)

Is that the DOHC equivalent of mechanical/vacuum advance on the distributor of a pushrod engine? Seems so.

Isn't the advance in the distributer to bring spark timing ahead of compression since the faster the RPM the earlier you need to fire plugs? (Fuel takes the same time to burn).

Watching your video has given me a thought on solving a problem with my 2007 X-Trail when cold. Lack of power until its really warm and even then it lacks grunt. You touched on wear inside the oil mechanism that controls the valve timing and a slight you get when starting the engine up..

Take out the vvt solenoid and filter and clean it thoroughly, just did that on my kia and it feels like i just unlocked 10hp extra, car is very eager to move on low revs unlike before when it would always want to stall. Also, don't forget to use the recomended engine oil for your engine, nothing thicker, vvt systems are very sensitive to types of oil.
