Thanks a lot, this video has finally answered my research,I was researching on how the actuator varies the opening and closing of valves whilst the timing belt or chain is rolling continuously
How come they dont mention thr carbon buildup after only 30k miles? 😟😟😟
Install catch can and port injection simultaneously
Yer on money with this. GDI is bull Sheit. Major PITA for people with no use for it. Go back to Manifold Injection, or combination if it makes the manufacture feel better. I'm done putting up with carboned up intakes, 80,000 miles & the valve track needs to be taken apart & cleaned. Crap in a can won't work past getting 50% of the crud out.
Major Disadvantage : the intake valves do not get the benefit of the gas cleaning off any oil blow by that might be on the intake valve. after the car shuts off the coated intake valves now harden into carbon deposits which increase the likely hood of engine knock.
@kill everyone yeah run port injection or add a methanol kit are two things i can think of.
That’s why a lot of GDI owners purchase an oil catch can to mitigate (to some extent) oil blow by
@@isaias9838 Oabsolutely correct that's fisrt thing I did when I got me Tucson and I discharge the foul smelling oil every 400 miles.
YESS
Ya fun, fun , in a world of Maintenace free engines, you have dump a can full of crap every few hundred miles. Up in the north land it's much worse, you can't even make this up how much crap it's produced & the owner has to clean it up, ya right, whatever! @@isaias9838
I've had to use 2 sea foam treatments through the spray that you put in the intake. Take the intake boot off and make sure u are spraying behind the mass air flow sensor. Have someone spray while you hold rpms at 2k until can is empty. Turn it off and let it hot soak for 10-15 min . Start it Rev it and drive it. If no smoke comes out. Drive somewhere park , let it cool and then eventually you will hear a pop and alot of smoke if you had alot of built up carbon like mine did. I may have to do a 3rd treatment . Regular fuel injector cleaner doesn't clean up by the intake because of how the gas is injected so anything put through the tank will help the fuel ( like water remover e.t.c. ) . Stay away from these and any cars with CVT transmissions, trust me.
Yep both ideas are meant for kids, sure as hell don't want to do this much care to a car now a days.
5.0TT would be great on the G80
If a 5.0 TTGDI came out people would love it
Nope. Carbon build up
nice to meet you hyun

Looks like they could easily fit an I-6 engine in there.
LS swap. lol
Scotty wouldnt recommend this engine

"Inside the carbon build up" ...
I was going put this exact comment then i saw this 😅
I got 316k km hyundai santa fe. No carbon buildup. Just change the timing belt recently. Runs like a champ.
@@christianmusicchannel8861 I think your petrol engine is port injection and not direct injection.
That's why it's clean.
@@Anas42M it says gdi on the engine cover.
Yuuup. I have to used the dang spray cleaner every few oil changes too.
The 2024 KIA Seltos SX 1.6L Turbo Smart Stream Engine is GDI & Port Injected.
Is the 1.4 GDi also Twin Scroll Turbo???and what about the carbon build-up between the intake valves???!
You will have more problems than that in time..
What is this a resolution for ants?
OMG. I've owned a 3.8 Genesis coupe track for 2 years and still outperforms most on the road. Just take care of your car.
Lol..2 years is a new car as far as I'm concerned. Still in zero-depreciation zone.
Consumerism these days. :|
Let us know how it does after 100k miles lol
2012 kia Optima 2.0 170,000 still runs great did the heads at 150 000 though......
@@Jte162 or 100,000 kms in Canada. GDI engine grenades and Hyundai/Kia won't honour warranty even in perfect maintenance record.
Man, I've been through the shakes with my car - Honda, thinking any day now. I just put cvt treatment in, and it's perfect again.
Due to carbon build up I sold mine and got a Camry that has both gdi and port injection. No cvt transmission either.
Many questions still regards to how does Hyundai prevents carbon deposit at the intake valve, a situation which GDI engine is infamous for? Toyota has got both intake and direct combustion injection which resolves this issue. How about you, Hyundai? I would like to hear from you. Thank you.
Ian Polo All the new GDI engines have the injectors located so gas is sprayed on the valves when they open. Since the valves rotate freely, the whole back will be cleaned by 2000 PSI spray. It clearly demonstrates this in the video. The older designs had the injection from above, hence the design flaw.
@@bobbylee2853 that's backwards. GDi doesn't clean the valves the way they should, hence why port injection was the better method. Look it up. Facts.
Peter Old technology was flawed, true. New designs available now wouldn’t have near the amount of carbon buildup like the old design. Believe what you want to.
@@theinvisibleman2070 Thank you for the correction 👍
@@theinvisibleman2070 The second reply is edited too, thanks to the infamous spelling auto correction. 😂
The gazoline direct injection and "GDI" slogan were used by Mitsubishi since 1997 !!!
3:41 for a fat drift.
Too bad the car can't actually drift
Super animation👍
شكرا على هذا الفيديو المهم وعلى مجهوداتك القيمة
What about carbon buildup on the valves? How are you preventing this buildup if fuel is not washing over the back of the valve like with port injection?
I swear there was this thing that would slightly rotate the valve each time the valve opens to slide it along the valve seat as to prevent buildup.
Tuning now the fuel goes in after intake valve is closed
@@jaygames1980 That doesn't change anything. Carbon forms on the valve due to oil from the pvc valve and anything that escapes the air filter. The gas would normally spray on the valve to clean it.
Will be dual injection system like Toyota.
Just decarbon it on regular two times per year. There are plenty of cleaning kits and service shops nowadays.
Proton also build TGDI for new engine.. good job Proton!👍
lmao carbon build up
Most of Proton cars are just rebrands
Most of proton car are junk
Have you solve the carbon build up problems, GDI?
@Chill Man using top tier gas like Exxon Mobil helps too with fuel detergency.. it's in the manual that you have to use TOP TIER gas which is available at alot of gas stations
You have to open the valves all the way for about 15 seconds. Try to reach 130 in the 2.4 GDI. Pedal to the metal will clear out the carbon buildup.
Hyundai can say what they like,it's still a direct injection system.The valves will still carbon up,the same as any other DI engine out there.
Like all other manufacturers,Hyundai fail to mention that modern direct injected engine produce 1000 times more poisonous emissions than the
old port injected units,(Tests carried out buy TUV NORD) In their report,TUV say this huge emissions problem can easily fixed by the fitment of special filters into the exhaust system,the cost? less than $50.
Time the world woke up and insist manufacturers fit these filters.
The engines are turbo. I only use high octane gas with in my 2.0 turbo Optima.
Also its an easy fix. Put some premium gas in and punch it a few times and problem solved!!
10 year 100k mile warranty!! My engine has a life time warranty covered by Kia. It's underrated at 274hp also. That's only on 87 octane, on 91 it's 285ish horsepower. I only run 93 octane. 6spd dual clutch transmission shifts very fast. Great little daily driver, close to 300hp and still gets about 26mpg city. The interior is ahead of it's time. All 4 seats are heated and cooled. Infinity sound system. Great car!!
@@boostjunkie2320 I've had no problems at all with my 2012 Optima 2.0 Turbo at 82K on 87 octane. Up to 35 MPG on highway with plenty of power when needed. I may try a tank of high octane to see if there's a difference.
@@ellieprice3396 what are your thoughts on idling the turbo for 30 seconds before and after you drive away?
My Hyundai i30N allready has an "OPF-filter" (Otto Partikel Filter)..my former Hyundai 1.4 T-GDi from januari 2019 had it also..in Europe we can't buy gasoline cars without OPF filters anymore..(EU-regulations).
@@gixxerboy555 What about your Hyundai 1.4 T-GDi engine? I have the i30 with this engine. What about carbon build up? Did you had any problem? I change oil and oil filter every 7.500km and use only 100 oct gasoline. Now i have 37.000km. What is your opinion? Thank you for your time!
عالی بود ❤
I Owen a 2019 veloster 1.6 turbo and it has so much tubro lag
How are you going to keep those intake valves clean?? ;)
They’re not. At 100k miles it will be trashed.
Manually, removing the freaking intake and brushing the hell out of it.
That was literally the only thing keeping me from getting the 2019 turbo veloster and instead going with the 2.0L naturally aspirated veloster. GDI engines don't last as long for that reason lol
exactly lol. if anyone want to go Di route i suggest toyotas with their D4S system. also dont forget the carbon build up on those DI fuel injectors lol.
Italian tuneup
How & where I will buy ..New Scaner Korea will Launch...GDS MOBILE TPMS FULL KIT ...INRODUCTION & PURPOSE TPMS FULL KIT ...PLS tel me if you know....
Everytime u see a comment with it involving carbon buildup, take a shot.
advanced muffin critical design flaw
advanced muffin The engineers have solved this problem by putting the injectors close to the intake valves. Some of the valve is in the spray when they open. The valves rotate over time, and are supposed to keep clean.
@@bobbylee2853 all GDI Engines? G4FD (KIA) too?
Олег Романюк The new designs with the injectors between the intake valves are a big improvement.
@@bobbylee2853
I understand, but whether all the motors have these changes. G4FD motor also?

can you tell me, which software use for making this type animation
if anyone know, say also
@@paglafapor00 it's made buy hyndai, he just copied that part and made a video. These are the video's techs watch in order to be certified. Idk but I'm just taking a pretty wild guess since my manufacture also creates videos like these!
@@paglafapor00 deep exploration
deep-exploration.software.informer.com/download/ someversions of this software supports that type of simulation but excluding liquid or gas simulations. you need autodesk or opengl with a physics engine for that.
Also
The simulation is very great! But for people having some gasoline engine culture, they understand hyundai have made 0 inovation beside the fact of starting to integrate already existing gasoline technologie/principe (well know since +-2006). This video actually describe what is a turbo gdi , nothing related to hyundai innovation here.. hyundai please hire ingeener now to develop something that you are able to patent for gasoline engine and most important to be prood of.. because now your compagny just look like to be waiting on other company patent expiration IMO
Hello Sir my name is Hossam I'm working as marketing manager at lubricant factory in UAE 🇦🇪
I want ask your permission if I can use your videos for arabica to my arabica speakers
I just want to know after all these technology improvements why I am getting 50-60% less fuel economy and more maintenance and service compared to a car I owned 10 years ago with similar power specs, whats the point of all this?!
Vehicles are much heavier and larger than back then
GDI engine made by Mitsubish 25 years ago.
Mitsubishi stopped making that there was no future for GDI engines.
Does Hyundai keep using old Mitsubishi engines because own can't make engines?
Excellent
With improvement to cleaning and ease of it carbon build up isn't really a thing
Even the animation has carbon build up as you can see..... Me no buy Kia...
Mammoth tank assembled.
So how do non GDI engines put gas inside the engine?
Usually the injector is placed just before the intake valve. Older systems used throttle body injection where the injectors were located in the throttle body.
Redtooth 75 thanks
man gdi looks different today
The GDI is not all it’s cracked up to be. Serious design flaws and poor quality control in manufacturing makes this is one engine to stay away from.
Huge problem with carbon build up in the intake above the the valve seats, the turbo only exacerbates this problem. The high pressure fuel pumps have a much higher incidence of engine fires.
Just take care of basic maintenanc and the engine will be fine
@@boostjunkie2320 no it want I did all that for two year got records to show and it still blew up waiting to see if I'ma get a engine now
@@LawezeanaS197 I got my 2018 Elantra Sport with 29 miles on it, I do proper maintainance, and I am now at 98k miles... not a single problem. And I drive it hard and it is Full Bolt on and Tuned with e30 fuel at 24psi. No problems here...
@@AlexGtheDon were did you buy your bolt on and tune from I been looking for stuff for my 2.4 for the longest and I brought mines use with 77k I love my car I just had one of those engine Alabama plant engine I was doomed from the beginning at least thats what Hyundai say's but they gone fix it I gotta pay out of pocket I didn't met the warranty
Yep. HUGE recall on the GDI engine. But, they will not accept ANY warranty claims when it grenades, even with perfect service record. (The service advisor said it was perfect.)
DOWN WITH GDI!
Ok. But why?
@@Glasses5x GDI has a few drawbacks. The main one is carbon buildup on the intake valves, on TPI systems the fuel injector washes most of the carbon buildup off the valves. With GDI this does not happen, within a relatively short period of time the carbon buildup reduces the efficiency of the engine. This can be fixed by using another set of fuel injectors in the intake that clean the intake valves, but this is an expensive workaround. GDI also uses extremely high fuel pressures that causes an increased risk of fire. The high fuel pressure increases the risk of a leak, and also makes any leak more dangerous. Many people don't like GDI since many systems are unreliable and don't think the slight increase in efficiency is worth the cost.
@sgfhk321 AAhaha! :D
Can I swap that 1.6 turbo into my RB 😅
Fentastic
I have a problem with my mitsubishi grandis model 2001. Regarding rhe coil #1 and #4 got no power. Please help how to fix it. Thanks
Change the ecu
Old news. Sadly, it's going to be a long stretch before ALL makers quit having dinner only. This is well documented to be the cause of serious valve carbon buildup on the back side without any pre injection coming from behind the valves to wash them clean this is an expensive fix all makers need to get on board with multi injection points
that is why we have to get a catch can
MPi inyection is more effective
@@danielsepulveda912 The manufacturer should have designed the engine right to begin with.
What is carbon buildup?
@@rohithchandrathonupunoori111 On older style multiport fuel injection engines the fuel injector is located above the intake valve. When the fuel injector shoots its fuel charge into the cylinder the gasoline vapor is washing over the valve thus cleaning away any oil deposits which could form into carbon. A GDI engine on the other hand has the fuel injector directly in the combustion chamber so the intake valve does not receive the benefit of the fuel charge washing over the intake valve. The reason for this design is by placing the fuel injector directly inside the combustion chamber the fuel charge can be more accurately controlled for better fuel mileage, performance, and lower emissions. This means that the intake valves must be cleaned by introducing a cleaning solution into the intake system from time to time at a dealer service department or other service facility. Many owners, such as myself, have opted to install an oil catch can to prevent minut amounts of oil from reaching the intake valve in the first place thus eliminating, or greatly reducing, this problem. Hope that helps.
it has a FLYWHEEL FORMED LIKE A X WTF
My BMW 3 series is the same
I love it
Can I add side injector to gdi engine
Verygood 👍👍
Could you tell me where is GDi injectors located? For hyundai sonata GDi model 2012 ..because I want to clean them ?
Aram Faruq .i would suggest you to go to service centre because injectors are cleaned in air tight room i heared that.which we cannot do that at home.and we dont even have have sysytem which cleans the injectors i means machine
just redline that hyundai
I still prefer old cars pre all this turbo charged anti pollution bullshit. An engine that works under these sort of conditions all sounds and looks good but they are not reliable and do not endure as long as non turbos. Based on what happens to some earlier nissans 3 litre TD which look like a fantastic engine do not last. The reason for this is they breath their own fumes as part of their anti pollution set up. Its in not unusual for the manifold inlet pressure to spike in a closed loop system. When this start to happen oil leaks out through the seals of the engine and deprive the parts of lube. It doesn't matter what brand of car it is. If you try to squeeze a lot of power out of a little block expect big problems. It all sounds good looks good and in theory works good but you can never get something for nothing. Everything has boundaries and we push them to the limit at the cost of endurance. Hard starts and oil leaks are the first signs of all this. I have personally see this happen to Nissans a great looking car and performs beautiful when they were new.
How and why the bue cold air turn into fire ??????? This is misleading
The turbo is very hot, being run by exhaust gases. This heat is transferred to the intake air via the compressor. That is why an intercooler is used, to take much of that heat out of the air before it enters the plenum.
@@ButchNackley thanks sorry for my harsh question. Since i was curious
I heared, The GDI Engine by H&K motor company accumulate carbone sludge at intake and exhaust valve.
It will be makes engine trouble.
It's really?
unfortunately yes over time. Many vehicles above 100k seems to be reporting this problem.
Very cool video.

Hi
Hyundai got twin scroll turbo charger😯
My 2024 KIA Seltos Turbo 1.6L Smart Stream Engine has a Twin Scroll Turbo.
As far as the brand? I read somewhere that the Turbo is a Borg & Warner K03 Twin Scroll Turbo.
ok...i was under the impression gdi engines lacked a butterfly at the throttle body?
Turbo ok👌👍👍👍👍
GDI=Gasoil Direct Injection
Worst engine ever, the oil consumption is unbelievable, the dealership is not supporting their customers due the the overwhelming failure of the GDI engine....I had 2 Hyundai Santa Fe. 2006 and 2017. The 2006 was worry free and reliable, Just did regular maintenance with oil changes and air filters.... Due to this I went back to Hyundai and got the 2017 Santa Fe sport... This was a big mistake that I'm still paying for. The GDI engine in Hyundai are no good... And it's starting to affect the brand loyalty... I hate the fact that they know there is a problem and they are ignoring their loyal customers.
These small boosted engines will not last!!
That's right, but it seems strange that the company puff piece fails to mention that. Not.
Alan Matthews: How do you know? Have you driven one to the point of fail?
It would be one thing to race them
it another to daily drive them...

the head's like fuck this! ive had enough, im outta here....
Nice info,,,l
Port is way better like honda vtec
Way better. But honda still the best producing engine. More complicated more fun to repair.
Honda has many realiability problems as well do your research
Test drove a Santa Fe auto, it was all revs and no go..typical rubbush auto box! Test drove 2 Tucsons and they both felt like they were built to a (very cheap) price with crap suspension and poor steering gearing. 1.7 CRDI diesel is ok but still a bit of a rough (Daihatsu?) engine. I test drive a Tucson 1.6GDI and it was absolutely bloody gutless, fxck all (no) torque. At least with a turbo it might actually pull uphill. I like the Hyundai body styles but you can stuff the engines possibly with the exception of the 2.2 diesel.
Do these engines have lower end issues like the theta engines do ? What is the horsepower rating?
Nah not so much. Dunno about horsepower but they make 150KW.
Inside the GDI Engine, you will find endless crusts of carbon build up arround the intake valves as thick as Kim Kardashian's rear bumper.
Yea and she is constantly changing her intakes too! Lol! 😂
These motors are junk if you don't keep the carbon out of them. You have to clean them every year. Best ways to take the intake off and sandblast the valves with Walnut shells Do that to mine every year. Tried to CRC carbon cleaner it works but not as well.
👍
Всё чётко и ясно объяснил,чувак учи русский!
I have an idea for a neat thing that I think anybody with a GDI will buy...
This isn’t John roblox...
I’m sticking with diesel.
Tru dat. Got my 7.3 Powerstroke. Tried and true. Never lets me down.
Yep my Ford Kuga/ Escape) has 2 litre diesel. Produces 370 NM at approx 1700 rpm and 400NM at 2000rpm. It pulls hard like a train uphill and begs to change up to higher gears.. never get that in a petrol until you wind it right up
@@mjames2117 did you ever drive a turbo petrol engine? It's the exact same feeling. It's the turbo that gives you low-end torque, not the fuel used or if it's ignited via spark or via compression.
Go drive a naturally aspirated diesel and then come tell us how it "pulls like a train". A naturally aspirated diesel is even weaker than a similar displacement naturally aspirated petrol engine.
@@Kain987 yes have driven a gsi Zafira..nice, quick but also very lightweight. Petrol torque curve is mid to high revs. A turbo serves to spool the engine up to their torque curve quicker and once turbo is running you have good response.
My Kuga/Escape has 350 to 400Nm between 1300 and 2000rpm eg low end and yes with the turbo. But it still has more torque than equivalent Cc petrol and a fair few other 2 litre diesels. If I am going up a hill in 5th gear pulling hard at 1500revs I guarantee your petrol will be in 3rd gear at higher revs needing to be worked hard and your turbo petrol will be in 4th gear and still revving higher because the engine still has to work harder than the diesel with its longer stroke and higher compression coupled with its higher energy density per unit volume. Some normally aspirated diesels did work well. I recall Renault 19 1.9?d were pretty decent.
MAZDA SKYACTIVE X ARE BETTER....

Just give me a car from back in the day when you could fix anything in your yard without a computer!!!! Then you knew what you had! Seems like more problems with technology & costs more than its worth along with more headaches! GDI is not up to par!! I'd stay away from GDI !!
