iVTEC How it Works -EricTheCarGuy
Автокөліктер мен көлік құралдары
iVTEC How it Works is a long standing requested video. Back with I did the video on the VTEC explanation I was asked about doing a video on iVTEC which is slightly different than VTEC. First you need to understand the basic operation of the cam shaft, once you have that, and you know a little about how that cam shaft effects performance, you can then begin to understand how iVTEC works. In essence, as far as the Honda system is concerned, it varies the cam 'timing' to optimize performance and fuel economy. Many companies employ similar systems to this but they may perform the operation differently. This video focuses on the Honda iVTEC system.
That said, you may notice that the VTEC system on this K series is a little different in that instead of having a cam with a higher lift and duration, it switches between 1 and 2 valves on the intake side. So when VTEC engages on this engine it actually activates another valve in the cylinder instead of changing lift and duration. It still alters cam timing via the iVTEC system however. Once again, to optimize power output and fuel economy.
Either way, I hope this video helps with your understanding of camshafts, cam timing, lift, duration, VTEC, and iVTEC systems.
Thanks for watching.

Hell yeah i just got myself a 06 honda accord LX 4 cylinder just now gettin broke in lol at 100k got it with 99,000 before i had a 08 toyota corolla until i totaled it n i gotta say i like my honda accord way better than i did with my toyota corolla its hard 2 say which 1 is better 2 me toyota and honda are about the same in terms of reliability but i always heard hondas automatic transmissions are a little on the weak side thats why im making sure mine i change the tranny fluid and filter and when i do that gonna put lucas transmission stop slip in there thats the only down side with honda is there automatic transmissions are on the weak side so if you wanna stomp on the gas and b race car driver your best bet is to get a manual trans. But as long as your doing normal everyday driving and dnt beat the shit outta your honda race it then the auto tran. Should last i would think
This series should be called "Eric Explains..."
Beautiful, Superb, difficult concepts in the most simple and practical terms. Congrats Eric you cleared all my concepts regarding the iVTEC. Two thumbs up for you.
I love the way you explain things that are usually complicated to explain into way even a non-technical person can understand.
Awesome video Eric. The analogy between computer program and what the cam shaft does for the engine was done!
Thanks. And very well done. Much more informative than several other well-known channels.
Excellent. Thank you very much for describing it so clearly and not speaking too fast like others I’ve seen on here. Good job.
Another awesome educational video from ETCG! I've always wondered what the difference was in all vtec systems now a days. Plus for someone like me I've done better with instructional videos than just straight reading it out of a book. You have no idea how thankful I am for guys like you to share knowledge like this.
Eric you have a great channel I've seen so many of your videos from fixing CMC to complete clutch replacement. great stuff man!!
Great learning session. I appreciate your concise way of explaining - makes things really easy to understand. Thanks.
Fantastic explanation in very understandable terms. Another great video!
Thaks Eric that gave me a better understanding of my Honda Accord Euro IVTEC engine. I never could get my head around how it worked! Thanks Mate Johnno
I like the -physicist-way you present your explanations. it is because you teach the principles, so understanding it is easy. thanks a lot. Nigeria.
A very informative video, Eric you are really knowledgeable on every topic discussed. I enjoy all your videos. Keep it up man, you're doing an awesome job. 😁👍🏼
Great job as always Eric!
Eric, Thanks for having a Honda Element! I haven't found a shop manual specifically for the Element, but I have made repairs by referencing your videos. I also enjoy your videos that don't feature the Element. Thanks for being there!
Thumbnail of video reads "ivetc" if no one has told you enough yet :-p always great info, Eric. Always humbling what little car knowledge i have. Hope everyone had a merry christmas, and happy new year!

Amazing video, I learned so much! This is my first time watching a video on this channel and I am happy to subscribe :) Keep up the great work.
always awesome work on your vids. I've been getting information from you for years and would like to say thank you.
A foolproof demonstration and explanation. , Thank you very much.
Thanks for this video Eric...i have been following your excellent educational lessons and this brought more clarity into how these systems work and relate. Please keep the good work up because students and professionals on the field are banking you guys.
Thanks so much for this. I'm just learning about engines and you explain things well! Keep the info. coming our way! 😀
Thanks Eric. Just learning about i-vetec & vetec.
Eric man; you, sir are a mechanical genius. I greatly appreciate your abundant wealth of knowledge, nay, even. Your ability to deliver said knowledge. We're not worthy!
As usual, thanks for the video on Honda product. I've got a 2003 Element still goin strong, and have checked out your vids several times for info. Keep those Element vids comin' ! Thanks again, very informative.
very detailed and good piece of information. Seems from what I know is it is exactly the same thing as VVT. You've done a good job of explaining it.
Thank you for this great explanation video!
This is why I love hondas.
Loving your videos, very informal, keep up the good work
Just like all of your videos, super helpful. Thanks bro!
Well said... Thanks for the infos and keep it up master mechanic ETCG!
thank you for this helpful video, I am excited to see more.
Very informative. Thanks again Eric
Thanks Eric for the informative videos
Very good video. Very informative. Thank you for posting it....
Thank you Eric very valuable information
Excellent video
Excellent video sir.
Thanks for the info, very interesting.
Great info and well explained.
great video!
great report thank Eric
Hi Eric, I like your video a lot, I can learn a lot from you....
A good followup video called "The Future of the Internal Combustion Engine - /Inside Koenigsegg" shows an engine that instead of using a camshaft, each valve is individually controlled by a electromagnet. Basically makes it so each cylinder can have its intake and exhaust individually tuned.
very very good video Eric
thanks. Very enlightening video.
Thanx muchissimo for the simple explenation on a complex topic ^_^
I've really gotten into Honda engines over the last few years. They're very interesting. My current dream car is a Lotus Elise with a super charged K24. Just gotta make sure I keep enough money in the bank. So I can jump on the first one I see with a blown Rover engine. And hopefully get it for dirt cheep!

nicewknd They started with the Rover, then switched to the Toyota a few years later.
Awesome video man I love learning!
great break down thanks.
Thanks for the education..
Thanks Eric!
I like your videos. THey are well detailed.
Good description!
thank you eric ☺
Each time I watch your video clips always so much to learn and so much to gain from them.Good explanation and good teaching right there. Thumbs up for you Eric.Aziegbemhinjacobpe.
Thanks for the look at the dual and single overhead cams and the explanation. It you take the i part of the cam apart, make a video, I'm kind of curious what that looks like.
Great video
EricTheCarGuy Please make a video in which you explain the Atkinson cycle and it's pros and cons, as well as the (so they say) 'pseudo-Atikinson cycle' that Toyota uses in their hybrid vehicle engines and what that's all about! Oh, and: Happy Christmas to you and your family, as well as a good start into the new year!
great video
Keep the video short. Straight to the point. This video can be done in less than 5 minutes
Good information.
This is the engine that kids like!
Thank you!
that's a fancy music box you got there.
Perfect you are my genius
groso, muy bien explicado. Fenomeno

I heard a rumor that somebody was bypassing all this complexity and going straight to fully-hydraulically-actuated valves, controlled by electronic signals. It allows full control of lift and duration at all engine speeds.

Explained well,!
have you been watching MIGHTY CAR MODS? HAHA cool video Eric! hope you had a great christmas and have a great new year.
Lol, the thumbnail brought me here. Waiting for the "VETEC" to kick in.
thank you
thanks Bro am from Iraqشكرا اخي انا من العراق
VERY important to change the oil regularly in those engines! Especially GM Ecotec!
Awesome.
will be great when engines finally have solenoids to control valves so we can have infinite variable valve timing for each valve

Koenigsegg now uses pneumatic for their valves instead of camshafts. I would imagine those are pretty much as variable as you'd want them to be. Cool technology for sure.

love it
Just had to replace that VTEC solenoid on my 02 CRV. Great video and explanation!
Kool, thanks
Pretty neat.
"""You know your stuff , well done """
Great Video! I think BMW accomplishes this same task with its "VANOS" system..
I-VETC for the win
Also, there is the VTEC system Honda used on the 6th Gen VFR800 motorbike. This system switches from 2 valves per cylinder to 4 VPC at a given RPM via the follower. Cleaver system but very time consuming & expensive in parts (shims and buckets) when doing the clearances. Honda stipulate this is done every 16k miles!
Nicely explained. It's still no turbo though!
Hi Eric, i recently wanted to know how the car parts works so im watching ur videos and its really helping.. Umm can you make a video explaining how the MiVec works?? And if u did can i get a link Thanks😊
Eric, are lobes always machined from a block as parts of the camshaft or can they be screwed onto the camshaft at different angles with Allen screws?
Eric want to thank you for all your great educational videos. I have a Question I've surfed the web looking for an answer maybe I'm just not wording things right. But i hope you may have some insight. So i bought my sons 1st car he wanted something to work on, we found a 1993 Honda civic DX Automatic with a D16Z6 VTEC in it. I noticed the Solenoid & pressure switch where not connected with wires actually cut. The VTEC is not working cause its not connected, I've looked and there is plenty of instructions on how to connect VTEC for a manual transmission using wires to the ECU seems simple enough. But i haven't found a video or any 1 talking about how to do a automatic for VTEC 1 video said opening up the ECU & having to unsolder & re-solder something in the ECU? Now can this be done or am i just stuck? Thank you once again. J & Aron in TN.
If you could possibly do a video on Nissan's VVEL that'd be freaking awesome
Cool
You should leave Friday to the true repair videos and select a different day for info type videos like this.
at 4:05, where the head is installed on the car-- why does the intake cam only appear to have a lobe with actual lift on the center? the lobe next to it seems to be just flat round. does this engine use the vtec solenoid to actuate a different cam profile or just to keep one intake valve from opening, increasing fuel economy?
hummm curious i haven't study closely the exhaust cam lobes to the intake lobes is there a 90 degree out of phase or something curious if they are all out of phase by a certain amount or if they all are a little different in phases.... i know they can have different durations (or sharper/longer lobes but not sure if there phase degrees between the exhaust and intake are always around the same for non vtec as well as vtec) ... it would stand to reason that one could make VTEC/iVETC all off of a motor or electrical means without any pully wheel or sprocket for the cam to get more optimal computerized timing some day
hey i got a question,. when you did the k24 swap, can you use the jdm motor with out the vtec solenoid, i seen the new engine did not have the vtec solenoid and you add it, so can i use that engine with out it or do i need the jdm ecm if i dont want to ad the vtec solenoid???
My bump stick has timing issues(it shoots out too early) but i still have fun with my bump stick. Wine helps me delay my timing a bit😝
k-series are great engine!

Actually, the head he took out of the civic was an R-series.
make a video of taking the head apart and changing the valve stems and changing the piston and the rings. thank you
Question!! So if it controls breathing for the engine in a nut shell and the power, how much power to the wheels does IVTEC increase?
good video. however you should mention that this ivtec you explain is on a dohc head. the ivtec on sohc engines like the r18 has a variable and computer controlled point of vtec engagement with respect to engine rpm. cam phasing on a sohc head would alter the exhaust timing too which may not be beneficial!
Dear sir, Please could you explain the iVTEC system specific setup on J35 Accord engines 8th gen + up? Answering: 1- if it has any affect on performance like usual VTECs? 2- How it really works to disable cylinder banks? 3-If it reduce compression during could start or whats happen during start making sound much higher and lower down after some seconds?
