Hyundai's New Theta Engine with GDI (Gasoline Direct Injection) Technology

[macgilliosa99]

only hyundai could make an engine that sounds this gay...

[memadmax69]

So, they took a diesel cylinder head, slapped some spark plugs in it instead of glow plugs, and stuck it on top of a gasoline engine block....

Brilliant.

[ps3dethman1]

My friend has a sonata with this engine he's put 65,000miles on it and never hade a signal problem.

[SNLGUY]

How has Hyundai addressed the oily buildup on the valve stems which attracts so much carbon the horsepower starts to dive after only 5K miles on the odometer. Ford and Cadillac have addressed this problem with new ECM's that produce ultra precise timing which has shown no oily deposits.

[ollonsvin]

@SNLGUY Because europe and the rest of the world uses better engine oil then in the us, here we change oil every 30000km

[GTAstuntking]

@SNLGUY Also they have this problem every DI engine suffer from carbon build up.

DI are not good for driving short trips.

Korean Junk

[treadstone323]

@thomasward00 bigger than your Junk, for sure!

[SendTheBitch2Mars]

I saw this video in class today with Radecki hahahaha!

[hazyazn]

RSX type S is better :P

2L = 210 Hp

[armwrestling23]

first nothing really new here second why don't car manufactures companies use Diesel type of piston with deep hole on top as those are proven to get better compression and it takes pressure off cylinders walls and heads = longer lasting engine with better performance using 3 compression rings and 3 oil rings would make an engine out live a human being lol. And you would basically never loose compression

[1stMrSceptical]

This is not direct injection ie: direct inject straight into the combustion chamber as diesel engines do, and the new Bombard two strokes there's nothing new here.. move on

[zackthegoth]

fancy, still gonna fail as soon as you step on it. }:)

[ReiDiGera]

I love it how the injectors sound like tinker bell when they activate

[dg5master]

WHY Hyundai DOESNT USE THAT ENGINE IN THE CARS SHIPPED TO SAUDI ARABIA ??? THE ONLY COUNTRY THAT DOESNT GET DGI ENGINE !

THAT WHY I BACKED AWAY FROM BUYING A Hyundai SONATA LAST MONTH,

RESPECT YOUR CUSTOMERS EQUALLY; HYUNDAI.

[BestestMoron]

@dg5master

(a) 'coz saudi sucks asshole.

(b) the camel jokies are dump as brick. You probably the only one in saudi that knows what GDI engine is.

(c) 'coz saudi sucks asshole.

[dg5master]

@BestestMoron Completely wrong

Your words tells that you do not know anything about the Saudis, and I think you never talked to any Saudis! Saudis are Encyclopedia in cars.

[summitsvift]

this is old technology abandoned by Mitsubishi

[klesmer]

@summitsvift Don't fret, if Mitsu is going to stay competative they will be bringing it back along with everyone else.

[wongyongjain]

compatible with gasoline ???

[NIGHTMAREuki]

how is this better than old Nissan VQ25DD that was introduced in 1999?

212 hp @6400 rpm and 199 ft·lbf @4400 rpm

[JTH6990]

sound effects in this video are gay

[weasel884]

lol id love to see how this motor would preform in my 5000 pound Buick.im sure i could lay some nasty tire marks but it would suck gas from the car being so heavy

[TheWizzardFromOS]

Wow I watched the nissan 1.6 liter GDI system video just before that one. They produced 190hp with their system (althouh with a turbo)

[intel220]

hundai!

engine without quality

[pattycarljackson]

@intel220 hyundais engines are actually best in class and the tau v8 ranked best engine for the last 2 years

[TheNuggetface]

Ski-Doo E-TEC Engine Technology kicks the shit out of this idea, why would you develop 4 strokes after seeing that????? 2 strokes are the future, lighter, lower emissions, more efficient, and longer engine life. win win win. they did do something better than what they had in the past here i guess, if you liked this video please just watch "Ski-Doo E-TEC Engine Technology" its amazing

[kumathebulldog]

@TheNuggetface um... no, 2 stroke engines are pretty nasty your knowledge of engines must be low if you think 2strokes create lower emissions than 4strokes.. engine manufactures would have to invest lots of money to refine a big enough 2stroke so it can power a car, making that car an expensive odd engine car that no one would want thus making it bad business for automotive manufacturers. if you hate 4 stroke so much get an electric car dude..

[diegomayan]

@kumathebulldog They invest in 4 strokes because they make more money with them....

[kumathebulldog]

@diegomayan LMAO 0_o is that so? can you please elaborate on your point.

[sangolt88]

@kumathebulldog With all respect, new two strokes are a lot different than the ones they made back in the 80's. Especially DI help 2-strokes get more fuel efficient and better performing. I think a 2-stroke DI car engine could work, if anyone are brave enough in the industry.

[hooknshlimer]

@TheNuggetface I actually have seen the new E-Tec video, and they have improved the two stroke engine, but they still burn oil, but they still lose intake gases out through exhaust ports wasting fuel, they do not have lower emissions then a four stroke motor, they don't burn cleaner than one, why do you think they quit using two-strokes in motogp ?

[boilingpoint2]

fucking good video animation !! 10 stars !

[Capkirk3]

I am an Assistant Service Manager at a Toyota Dealership, my brother builds the Camry, Venza and Avalon. My father owned the Toyota Dealership in my hometown for 20 years. Im happy and proud to say that I just bought the 11 Hyundai Sonata. I love it!! Great car for the money!! great

[Motorfordtoyota]

Ecoboost and ecotech are better. FORD AND GM ALL THE WAY!! With a little Toyota thrown in too.

[youngbleeb]

Everyone's got a GDI 4cylinder engine now.. they all had a good 5+ years to copy off of Mazda....

[Heebda]

Its "THAY TUH"

[eraserheads78]

Correction, its not 200hp but a 176 @ 6000 rpm.

[Ksport07]

@eraserheads78 nope it's 200 hp in US where the GDI engine is used. Outside North America, it's a less powerful engine.

[adsabine1]

The timing chain looks like it would cause a lot of friction on the "chain system" and not that impressive HP for a 2.4L.

[1tb4life]

These engines are gonna suffer from extreme carbon build-up and end up dying. And the ones that don't die will have constant problems starting around 30k miles.

[chrisw40]

@1tb4life yea right is that why they have 100,000 mile warranties

[psychotikpaisano]

wtf, this music makes my head feel funny...

[kibetster]

Love ,Love Love Engines,Awesome presentation of a GDI Engine
