iVTEC How it Works -EricTheCarGuy

[@WAVETUBE84]

Hondas are really good cars!

[@kerron_]

266k Hell yea

[@thomasy76]

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

[@wsman1098]

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.

[@That1BlkDude]

This series should be called "Eric Explains..."

[@ericthecarguy]

In case you ever wondered how iVTEC works. kzbin.info/www/bejne/iXO9fZaeZsysla8

[@biancaboobchamp1078]

Everyday is a learning day. Thanks Eric 💋🎬🇬🇧♥️⛄️

[@Erik_Swiger]

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.

[@zzzingrol]

Erik Swiger F1 has been doing it for years.

[@xFreeland1]

Erik Swiger koeniggsegg has been doing this for a while. (Correct me if I'm wrong)

[@TheBrownGarage]

xFreeland1 nope your right, i saw a vid by them a few years ago and they had modified a Suzuki head and they were runnin the engine with no cams, all hydro valves computer controlled

[@federalrj94]

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.

[@Michiganborn1969]

I love the way you explain things that are usually complicated to explain into way even a non-technical person can understand.

[@robt6127]

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!

[@ericthecarguy]

Rob T Fixed it. Thanks.

[@dolssondko]

Awesome video Eric. The analogy between computer program and what the cam shaft does for the engine was done!

[@anaeleraphael8725]

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.

[@christianpetersen1782]

Excellent. Thank you very much for describing it so clearly and not speaking too fast like others I’ve seen on here. Good job.

[@tdcblackmamba4787]

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. 😁👍🏼

[@Mr.M1STER]

This is why I love hondas.

[@ARayMaddy]

Great job as always Eric!

[@SpacemanXC]

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!

[@SpacemanXC]

nicewknd They started with the Rover, then switched to the Toyota a few years later.

[@Larpy1933]

Thanks. And very well done. Much more informative than several other well-known channels.

[@johnkinnane547]

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

[@sdietri22]

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!

[@InsertFlashyName]

Fantastic explanation in very understandable terms. Another great video!

[@someusername121]

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.

[@Dieaap]

Great learning session. I appreciate your concise way of explaining - makes things really easy to understand. Thanks.

[@jamesdahmer5027]

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!

[@Subawu_jku]

Eric you have a great channel I've seen so many of your videos from fixing CMC to complete clutch replacement. great stuff man!!

[@komanemolefe107]

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.

[@iandaphmckenzie9257]

Thanks Eric. Just learning about i-vetec & vetec.

[@SebSar-ef4zj]

A foolproof demonstration and explanation. , Thank you very much.

[@aswad7368]

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.

[@dineshmourya904]

Keep the video short. Straight to the point. This video can be done in less than 5 minutes

[@evilcowboy]

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.

[@teddyruxbin7769]

always awesome work on your vids. I've been getting information from you for years and would like to say thank you.

[@djwak59]

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.

[@hyundaiverna]

will be great when engines finally have solenoids to control valves so we can have infinite variable valve timing for each valve

[@johanneswarn5488]

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.

[@The_Noticer.]

@@johanneswarn5488 But for a reason on a car as expensive as that. It'll for sure be less reliable and more expensive.

[@RGaneshOneFive]

Lol, the thumbnail brought me here. Waiting for the "VETEC" to kick in.

[@dosman01302]

VERY important to change the oil regularly in those engines! Especially GM Ecotec!

[@Seegalgalguntijak]

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!

[@LJC123]

Thanks so much for this. I'm just learning about engines and you explain things well! Keep the info. coming our way! 😀

[@antoniocarrasco3808]

Loving your videos, very informal, keep up the good work

[@goodsh1t92]

Just like all of your videos, super helpful. Thanks bro!

[@cigarobsession]

Awesome video man I love learning!

[@hindflight]

Great Video! I think BMW accomplishes this same task with its "VANOS" system..

[@TranceAddictFoX]

Very informative. Thanks again Eric

[@zzzdogutube]

Thanks for the education..

[@yearbattery]

Hi Eric, I like your video a lot, I can learn a lot from you....

[@thetsuchiyasan1000]

Well said... Thanks for the infos and keep it up master mechanic ETCG!

[@PL-KLIPHZZX]

Thanks Eric for the informative videos

[@Rsguy1776]

thank you for this helpful video, I am excited to see more.

[@johnreid859]

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.

[@bikemaurice1953]

Thanx muchissimo for the simple explenation on a complex topic ^_^

[@ctscantechnologist]

Very good video. Very informative. Thank you for posting it....

[@henrylee2964]

Hi Eric: based on Honda service bulletin 13-085, the Honda J-series engine with iVTEC system causes the engine to start prematurely oil burning in cylinders 1 ,2 ,3. Apparently, when iVTEC engages, this causes the rings to roll on the pistons which in turns causes oil burning. Can you shed some illumination on this topic. I dont understand what is going on. Can you do a video on this interesting situatioin?

[@jacobekoba200]

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.

[@ablackformula]

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?

[@HusamGibreel]

Thank you Eric very valuable information

[@zzzingrol]

It would be interesting to see power and torque curves with and without ivtec active.

[@trankt54155]

Use Google to look it up...

[@Coldfin9er]

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!

[@AlexandreLollini]

Vtec is the dual cam lift mechanical (two different lobe sizes for same valve group). VTC is the timing of the cams software controlled VTC is only on the K series, while vtec is on most Honda engines. Programming using hondata device has another layer of work on the K series of engines. Vtec has no equivalence in the other brands (no system can change both duration AND lift of valves) while VTC is almost equal to BMW Vanos system (phase timing). I thought it was necessary to differentiate the two sub systems.

[@Paint0nBrush]

that's a fancy music box you got there.

[@grantlarmstrong]

Great info and well explained.

[@fordwindsor351]

You should leave Friday to the true repair videos and select a different day for info type videos like this.

[@EddieNYC02]

Thanks for the info, very interesting.

[@shivarajkumarkalsa7203]

Excellent video sir.

[@nintendoatarikiller]

This is the engine that kids like!

[@Darren.G]

This is awesome knowledge overload. The intricacies of this system are amazing. Nothing better than telling a VTEC owner what VTEC actually is and does. Are there any other motors (non-honda) that have a similar system?? Or is the Honda VTEC a one of a kind??

[@SqueezeTop]

bmw has Vanos

[@Darren.G]

Whoops used the word 'motor', Should be 'engines'. Don't let the trolls see that.

[@PiMpLiChEeSs]

Darren G. I heard that VVTI is basically the same. i don't know though.

[@evilcowboy]

arnaldo vargas I had heard the same thing. Many companies just dub the same thing under a different name so it wouldn't surprise me.

[@neverknowsbest4994]

almost every car manufacturer has "variable valve timing" which is essentially what vtec is. its not a honda thing by anymeans. and im a honda owner

[@paulocaetano4339]

I like your videos. THey are well detailed.

[@jayyoutube8790]

I am mystified by how "smart" cars have become, just over my life time.. Awesome

[@thormcgee968]

BMW has dual VANOS that changes the cam timing on both cams that is similar in concept as iVTEC. The M54 engine has dual cams with dual VANOS and hydraulic lifters that don't require adjustment. The bad is that it has an aluminum block and when you over heat the head one time, it will pull all the head bolts straight out of the block from the head swelling and ruin all the threads. Ask me how I know, go head, ask.. haha

[@Naturalxlegend]

thanks. Very enlightening video.

[@flipdog0123456789]

You should really do a video on how VVT-I and VVTL-I work.

[@Haloruler64]

He'll have a heck of a time finding a 2ZZ powered car to show off VVTL-i. They're not all that common.

[@Michiganborn1969]

I had the VVTI on my '04 Toyota Celica GTS. Awesome engine. Was almost unbelievable it's power output was equal to it's displacement. 1.8L that could put out 180HP.

[@lukethekanefan]

ITS EXACTLY THE SAME

[@lukethekanefan]

Haloruler64 really there not rare in england iv worked on em a few times

[@Haloruler64]

lukethekanefan they're not rare by any means, just uncommon. I don't see many Celica GT-S's around anymore.

[@shaneklazema6912]

very very good video Eric

[@vasily9864]

great video!

[@daveduznotrull]

have you been watching MIGHTY CAR MODS? HAHA cool video Eric! hope you had a great christmas and have a great new year.

[@Kennynva]

Hi Eric...so your saying the computer CPU...controls solenoids that send oil to the mechanism to change the timing and the amount of lift each camshaft has...so in a sense is this why you can change the computer chip inside it to gain more control over that system..???? or have a completely separate CPU or control (box) that could be adjusted on the fly...

[@kiykim277]

So does that mean the iVTEC kicks in different rpm depending on the scenario?

[@andrew21030]

Ki Y Kim That's the one. So if you're flooring it in a low gear then you'll get VTEC happening later but if you're in a higher gear you'll get VTEC happening earlier but if you're at high revs and increasing them slowly in a low gear then you won't get VTEC. Another way to view it is that it's really difficult to replicate a scenario for ivtec to happen as it takes in so much data but VTEC will always happen at a certain point.

[@Patspwnage]

My K24A3 ivtec has been ECU reflashed to always activate at 4600RPM WOT

[@joshuatorrez7608]

Patrick Patrick what I didn’t know you could do that. That’s crazy! What does WOT mean? Could you do that on a Acura TSX?

[@atillalawyer8526]

thanks Bro am from Iraqشكرا اخي انا من العراق

[@sheharyarzahid7700]

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!

[@waynewilliams1487]

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😝

[@commodore665]

interesting video , my car has variable length intake runners , I Googled that to see how it worked , I realize that iVTEC YO, is not the same thing as variable length runners , but I find it interesting how my car works . seasons greetings to Eric and to all

[@ericthecarguy]

[@guzforce]

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?

[@danielclarke2477]

bought my 06 accord (same engine) in 2011 and have not had one single issue with anything in the car since, ivtec is definitely noticeable when passing people, but I can only compare with my 04gmc grand caravan lol

[@marklennon1]

Good description!

[@rinu123]

Newton metre is a unit of torque not power as stated in the video.

[@abaubaidah]

[@carslover3509]

great report thank Eric

[@eternalblue2119]

will this fit on my honda

[@Cabover_Kid]

More than likely, most Honda parts are interchangeable ,just find a head that has ivtec and get an ecu from a bond prelude with an h22

[@BrbReactions]

only true fans will understand this. haha chopped

[@AlexandreLollini]

Hello, I think the name of the feature that change the cam timing on the fly is VTC (not iVTEC wich is the naming of the engines of a family) the explain and the principles are right, it is just the name of the thing "VTC".

[@neverknowsbest4994]

vtec is just what honda calls their "variable cam timing. vvti is what toyota calls their variable cam timing. every manufacturer has the same thing under different names.

[@ParadoxdesignsOrg]

Nicely explained. It's still no turbo though!

[@AamirZ]

So this is very similar to the Toyota 1.8 190bhp 2ZZ-GE which has VVTL-I which has both lift on the intake and exhaust valves and intake timing change which the VVTI only engines also have.

[@lukethekanefan]

the I-VTEC and VVTL-I are identical

[@gyrgrls]

iM surprised that Apple hasn't sued them yet for trademark ambiguity...

[@godfreyemmanuel3097]

SSShhhh don't give them ideas.

[@1GTASANANDREASCJ]

That's why it's called "I-VTEC" and not "Ivtec" ;-)

[@plinkynut]

John Bond the i in i-vtec stands for intelligent.

[@georgioarmani6948]

Lol should be the other way around. i vtec was designed and came out before the i phone was release and invented. Smfh. Honda cam technology was the first of its kind from late eighths now all manufactures copy the setup

[@iconr6racer]

IMac came out in 98, I VTEC was in 2001..

[@jakesnake_27]

Just had to replace that VTEC solenoid on my 02 CRV. Great video and explanation!

[@8487glaz]

just to be accurate the camshaft lobes only open the valves they don't close them. valves close from the tension of the springs. its not a desmodromic system that the cam actually opens and closes the valves..

[@neverknowsbest4994]

technically they do not close the valves, but they do control when and how quickly they close due to the other side of the cam lobes.

[@sam111880]

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

[@markanderson2904]

I don't think the "i" means that the valve timing is adjusted. My Honda iVTEC engine does not have a cam "phaser" to adjust the timing. The iVTEC engine activates the long-duration, high-lift lobe for economy whereas the VTEC activates that lobe for power (as in the K20 engine). The cam phaser on your engine is part of the VVT system.

[@janrichter7965]

groso, muy bien explicado. Fenomeno

[@MyEbaymods]

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???

[@NiTheGod]

sounds naughty when you said have fun with your bump sticks

[@adnanrp945]

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😊

[@SciFlyZ]

great break down thanks.

[@tannerhalo3]

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?

[@chodkowski01]

I believe on my Honda Civic I have a switch that has 3 settings Economy/Normal/Sport. I believe that is the I in I-Vtec.

[@RobPhiangdae]

make a video of taking the head apart and changing the valve stems and changing the piston and the rings. thank you
