Comparison of MIVEC, VTEC and VVT

Comparison of the variable valve timing systems Mitsubishi MIVEC (2 cam profiles), HONDA VTEC (3 cam profiles) and Toyota VVT (4AGE black/silver top engine with adjustable cam gear).

[@Trixie_I]

Thanks for the video, even 15 years later it helps people out, the Japanese really helped me fully understand it and thanks to the subtitles I was able to learn so much that I'm now an engine engineer at Mitsubishi motors.

[@travef9]

From what I see, Mivec and Vtec run on the same priciple which is 2 primary cam profiles. One for low end torque and the other for high end. The VVT is not nearly as good because it only adjust the timing on a single cam profile. The new iVtec is basically a cross between VVT and Vtec/Mivec. All in all the newer motors seem to be pretty impressive

[@Bobadillak100]

the video just says, that at the end if u want more power, u need a turbo.

[@elite128]

I love japanese technical videos because they always have some sort of quasi rock background music w/ B.A guitar solos

[@johnny1appleseed]

The MIVEC vs. VVT-i is a pretty fun race. I raced my buddy who has a 2008 Scion tC, HKS Cold Air Intake,removed catalysis converter, and Magnaflow exhaust vs. My 2011 Lancer with Magnaflow exhaust. He had the advantage in weight and take off the line, but I had the advantage of power in higher RPM's and MPH.

[@mibars]

You know... VTEC and MIVEC does exactly the same thing :)

[@michaelhall3619]

Oh really ? Like the same exact thing? Or are they slightly different

[@MForrester]

@@michaelhall3619 MIVEC feels like smooth change ...VTEC feels like an abrupt change over.......the differences never bothered me

[@meandmyevo]

MIVEC gives variable lift and duration(phase as you call it) for intake AND exhaust. exactly the same as VTEC. if you look at the cam lobes in the MIVEC engine, you'll see that one cam is taller, fatter, starts earlier in the revolution, and ends later than the other. thus greater lift and duration. if you look at the cam profiles for a VTEC engine, you'll have a hard time telling them apart as they look almost identical.

[@EngineeringExplained]

For English, you can watch my videos in the video response section. Though I've only explained VTEC and 3-Stage, but at least it should be clear.

You have wowed me with your words of wisdom. I now totally agree with everything you say. I am hypnotized by your eloquence as you must be as much a master of engines as you are of spelling and grammar, as well as wit.

[@meandmyevo]

I was talking about the engine itself, not the whole car. Toyotas are less efficient due to heavier duty parts because they are overbuilt like you wouldn't believe. You wanna know how many civics, accords, preludes I fix every month? a LOT more than the camyrs'(sp?), corollas, prius's(??), yaris's's's(?!?!?!), echos and all those. I AM my info, I've been an ASE certified drivetrain repair specialist for 20 years.

Also in the Lancer and Mirage...The 4cylinder mivec engines put out the same power but MORE torque then the same honda engine. 4g92 (1600cc MIVEC) vs B16a (1600cc Honda) Google it...

[@beyondthegrave2005]

It's the same system at heart, just Toyota wanted to up the standards... by the time of the AE101 the VVT system was upgraded to VVT-i, in which valve timing was more electronically supported. VVTL-i is the same system, just it's running on dual adjustable cam gears instead of only one like its predecessors.

[@summitsvift]

I own Cyborg Rs, hope will keep it forever

[@jkralowell]

Correct. The BMW-based technology for (continuously) variable valve lift is brand-named as "Valvetronic". Valvetronic & Vanos work together. I don't know wether Valvetronic beat Honda VTEC to market - but I think it came out around 1999, and I recall it won an "engine of the year" award in it's category. I'm too lazy to try to describe the Valvetronic approach, but it's very different than the approaches shown in these videos (although the essential concept is the same).

[@delfartel]

@1PARADOXXX No you can clearly hear mivec, i'm pretty sure every variable valve timing system you can hear when it is working.

[@tenkuunokage]

thank you for posting

[@82raptor]

If you notice on the honda system the intake valves in non vtec open at different times and for different duration for better low end torque and unleashes the dogs in vtec... the others dont do that... which is another reason that in my opinion the honda is the best. GOOD VID

[@crxdelsolsir]

By the other manufacturers comparing their valve controls systems to Honda Vtec they not only prove that Honda had a working (not gimmick) valve technology but also shows that Honda was ahead in engine technology as Vtec was around years before Mivec, VVT, VVTi, Vanos Copies etc

[@crxdelsolsir]

Commercially anything that makes power comes at a premium (since power is what everyone wants) hence even if it is old tech (turbo) it is still an option or reserved only for the premium models. Same reason that powered seats, leather and sunroof has been around since the 60's (manufactured cheaper today) and is still a premium and reserved item. But in the intellectual side, producing the same hp or overall performance w/out force induction is regarded as more admirable.

[@Maccattack77]

i think what slzkilla was tryin to say is MIVEC was designed as an aid to a turbocharged engine. it was designed to assist with turbo lag, because the evo engines are all turbocharged. Whereas with the honda vtec, it was designed purely for NA tuning. so in the comparison on the video, VTEC would out perform the MIVEC when just considering the NA side of things. It could for all we know outperform it on the turbocharged side of things too. although i doubt it. they should compare Vario-cam too.

[@ldiddynyc]

yup. plus timing tech helps when you have RPMs to work with after it kicks in. That's Honda's specialty with 8,9, and 10K RPM engines. ;)

[@dan8852]

beautiful engineering

[@StratfordDanBurrell]

@Descente36 I've not only heard of it mate, I've owned one! I had a 1990 VX-S Galant with a high compression 4G63. It wasn't the engine that was problematic, it was the rest of the car, the electrics, the sundries and accessories. Plus it was pretty heavy and the handling was a bit to be desired. I do believe the Evos and GSRs are excellent cars, but even then still expensive to fix.... still much rather a Mitsi than a Subaru even then.

[@RXHardstyle]

@1PARADOXXX it depends on how aggressive the cam profile is

[@fidelcatsro6948]

soon we can expect variable piston displacement timing, variable connecting rod timing, variable compression ratio timing, mechanics will be getting more and more headaches as well

[@moisescaravali9653]

[@Gabrielkgaray]

[@blondie576]

nice video r4pt0r mit den vid sieht man gut wie der motor aufgebaut ist und die nockenwellen schaltet :-) frage: Coltmania?

[@johanz007]

It's true that B16b is better than 4age in term of performance, but on track we r not only considering the engine performance. Turbo is faster compared to NA engine but on track it sux. On track, handling is one of the most important thing. Remember 2nd profile of vtec's cam is nearly 300 degree, but 4age don't have this kind of 2nd profile cam's degree at 4 - 5krpm. VVT also do not give any performance output, it only helps to optimise the fuel efficiency. It's basically a normal 1.6 engine.

[@crxdelsolsir]

Yes it does. Thats the whole point of the comparison. Being the best in the same category is all about having more (or the most) amongst your peers (under the same rules and restrictions & category). You cant argue against the most powerful 4 cylinder turbo car by throwing in an argument about a 6 cylinder turbo car, or an 8, 10 , jet or rocket car. The best - is finding a way of having more (than your peers - under the same conditions - could not ). The little things makes the difference.

[@flinchey]

mivec is also meant to work from a much lower RPM range than VTEC, though without the whole OMG VTEC JUST KICKED IN, that happens when VTEC goes off above 5-6k.

[@meandmyevo]

i completely agree, but admirable doesn't win races, torque does. the most powerful engines in the world use forced induction for a reason.

[@thelocustemperor]

[@mando8000]

its just fun and most people dont need or cant afford a 300hp car. i drive my 99 si coupe around hitting vtec all the time like i said its fun

[@abec666]

Kinda yes.But trust me low cam works better from a high cam at low-mid rpm range so 2 cam sizes is not bad.But yes Hondas start to pul from 3800+.Its not a problem if your redline is at 9k rpm.

[@albikavo]

I'm not saying this because I have the mivec. But the Vtec controls only the exhaust valve timing. But the Mivec controls both Intake valve timing and exhaust valve timing. What you may have heard is that hondaq engines with vtec have a higher power output. But that is just the peak power at high rpm but the low-end torque is horrible.

[@PrimeTimeGrimester]

@EthansOpinion92 Actually I believe toyota recieves assistance from yamaha on developing the valvetrains of their hi output engines

[@macthemec]

I was not refering to honda in the 90s, I was talking about BMW now. i-vtec is just the old Vtec with an electronic butterly (something BMW debuted in1988) so the driver won't notice a cam lobe changeover. do a youtube search for valvetronic and Vanos(which has always been on both camshafts) and tell me what you think then.

[@94XJ]

FIAT had the first VVT system and GM developed VVT in 1975. Alfa Romeo was the first to mass produce VVT. Nissan beat Honda as well with the VG30DE in 86...VTEC finally showed up in 86.

[@mikey380sx]

@1PARADOXXX No...there is a pretty noticeable change in the diamante DOHC V6 mivec...well the ones i've heard anyway

[@meandmyevo]

I couldn't agree more that Honda focuses zealously on producing a good engine, and I can't argue that they usually do a damn good job. However, their VTEC system just is not at all dissimilar from or superior to many other VVT systems.

[@slzkilla]

OK first of all , all the credits goes to Honda becuz they were using F1 technology to develop a variable valve timing engine. since they only had 10 years copyright, toyota quickly took this design and so did bmw. they improved on these the design and made engines like toyota's vvt-i and bmw's valvetronic

[@flyingdegu92]

@henry51563 actually a stock crx with a b16a with y1 trans will do low 15's high 14's in a quarter mile on street tires. while a stock 5.0 mustang will do 14.5-15 second runs..

[@anthonywendt5834]

[@lazio20roe]

he is truly wise beyond his years

[@crxdelsolsir]

I agree rotary puts out more power per displacement than a Honda (both being N/A). However look at the draw backs on a Rotary. Small displacment yet sucks gas like a large engine (economy is crap), chews oil like its gas (higher maintenance), wears out faster (since its cylinder wall surface area is significantly small), and once its worn it cannot be rebuilt. In a race called everyday life (that lasts longer than 4 hrs) and a budget that is not in the millions i'd have a Honda any day.

[@Greg11980]

In my oppinion, and I know (no one asked) is the one that can rev the highest reliably with out breaking, and idle at the lowest rpm. If it can rev higher and make good power over a good spread and idle lower making good economy with good torque at a low rpm up until mid rpm that would be the best engine and and honda is close. Best for the money

[@boyishiyah]

@EthansOpinion92 actually mitsubishis engines are powerful and reliable and they have the first ever diesle engine in a car with variable valve timing so dont diss mitsu :)

[@meandmyevo]

I hesitate to say that the new "advanced VTEC" is an IMPROVEMENT, as much as an alteration. instead of using different cam profiles, they are using different rocker arms... different way of doing the exact same thing.

[@hugonubario]

@amnesia2810 good question!

[@Metalhead852]

Yeah I would say Honda and Nissan have really nailed down n/a engines. I would say that's why both really outlast the rest of the compition.

[@crxdelsolsir]

It actually proves Honda's are better as they need to be large displacement and/or forced inducted to beat a Honda. That is exactly what Honda claims, their engines are equivalent in power to a larger displacement engine!! Honda is the Best!!

[@albikavo]

About who takes of first is a matter of torque car weight etc. Do a google search for k20a dyno and 4b11 dyno. Look at the torque curves and see that the 4b11 has higher and flatter low end torque. It is just a matter of tuning 520a is tuned for high power output. That just means that its powerband its in the high rpm

[@meandmyevo]

Honda does build a pretty bulletproof motor, but I've seen a MIVEC go through HELL and keep going. just look at the WRC Evolutions!

[@crxdelsolsir]

You forget that needed twin turbo and a 5.5ltr engine to perform the way it does. F1 in the turbo era only had single turbo, smaller displacement of 1.5 litre and no doubt lower boost.

[@crxdelsolsir]

No they are not identical. Whilst Valve technology of varying the timing (duration it is open or closed) Honda also had variable Cam technology varying the travel (lift) of the valve. Honda had variable timing and lift for both Inlet and exhaust of the engine. Other manufacturers only had variable timing only on the inlet, or only the outlet or both but no lift. Later they may have timing and lift but only on inlet side only, or exhaust side only. Honda gave everything everywhere.

[@Boujai12]

well, they re all japanese so they are all good...

[@crxdelsolsir]

Cylinder engines are the most practical and proven format. Hence not everyone is using Rotary.

[@PedroSilva1988]

MIVEC IS THE BEST...Nm(kgm)/rpm

[@Imreadingthisaloud]

@ForlornDespair ur entitled to your opinion, and i respect that. Personally id rather have something that performs as best it can, right on the limit. I see the american V8s as unrefined...maybe its my cultural back ground, but thats another debate!! :) we've all got choices on our vehicular transport, enjoy wotever u drive!

[@darkenddream]

yea ur right but wut about the civic DX for example how good r those r18a1 engines

[@Imreadingthisaloud]

I dont speak this language..but the number speak for themselves. 4age is 10% lighter than the others and has 90% of the compression ratio of mivec and a BETTER ratio than vtec. 4age is the clear choice for me. Mivec has some impressive figures, just a bit hefty for me :)

[@TheBassPlace]

maybe a dumb question, but is this movie available in english somewhere?

[@Nic0ya4Ever]

@henry51563 The only reason V8's make power is becuase of how many cylinders they have and the HUGE displacement. It's truly amazing engineering when you can get 200+ horsepower out of a 4 cylinder with probably a third of the displacement.

[@crxdelsolsir]

Give me your question and ill answer you right back with facts.

[@4aGeCeresGt]
