4 or 5 percent is a massive improvement for a heat engine. Even increasing the efficiency of the engine by about 0.5% would be huge. Especially nowadays, where combustion engines have met their limits.

기존 기술인 CVVT(언제여느냐)와 CVVL(얼마나여느냐) 기술을 합쳐서 사용하면, 기간(듀레이션)을 조절할 수 있습니다. CVVT(언제여느냐)로 열리는 시작점을 정하고, CVVL(얼마나여느냐)의 하이캠을 사용하는 경우 열리는 기간이 늘어나고, 로우캠을 사용하는 경우 열리는 기간이 단축됩니다. 단, 하이캠을 사용하는 경우 열리는 기간이 길어지면서 흡기 밸브가 많이 열리고, 로우캠을 사용하는 경우 열리는 기간이 단축되면서 흡기 밸브가 적게 열리게 됩니다. 그래서 흡기밸브를 짧은기간 열게되면 적게 열리게되고, 열린면적이 적어지게 되면 저항이 강해져서 공기가 원하는 만큼 들어가지 못하는 단점이 발생하게되는거죠. 바로 이 단점을 해결하기 위해서 CVVD를 개발한 것입니다. 즉, 흡기밸브를 '짧은 기간' 열더라도 "많이" 열고 싶은거죠.

Koenigsegg freevalve is expensive to manufacture. Technology like these are nothing new, its just cost and reliability prohibiting them. Everybody knows if the engine bay can be made "variable everything", we can achieve great efficiency and power. Alfa romeo invented variable valve timing, honda made it affordable and reliable, then it became continuously variable with electronics (instead of fixed at certain rpm with two sets of cam lobes being pushed in and out at certain rpm. Then we have variable turbo geometry, which changes the turbine's compression rate, then nissan did the crazy variable displacement engine which changes the crankshaft and conrod's angle to change the stroke of the piston, absolutely bonkers, and now hyundai's variable valve duration, which isnt just timing of when it open or close, but how much it opens or closes can be adjusted, a big breakthrough instead of just two cam profiles to choose from. Mazda's innovation is crazier than this the HCCX is wilder, costs lesser, cleverer, and saves way more fuel while produces much more power. The breakthrough is how fuel burns, not how lean the air fuel mixture can be at times. So far, HCCX seems to be the most promising, using spontaneous honogenous combustion to create diesel like burn rate and efficiency. But just imagine if all these technology comes together in one engine. Mad mad achievements. But costly and probably not reliable.

180
@@avalanche15301 the best high rev I4 engines produced around 200 hp in the past. Modern gas savers are on another path. You can keep boosting the engine by turbo, but it doesn't mean the engine is good. From engineer's perspective. Only "bad" engine needs boost. Boost is the last solution of meeting industry requirements.
same as toyota dual vvti ?
But the engine American still the best it is like a monster
안 깨지고 무사히 양산되기를 바라겠습니다.
Damn, now that's a promising engine.
ㅎㄷㄷ
if in fact this is a gdi motor, STAY AWAY unless a factory installed catchcan is installed
Но при етом они ставили натяжитель цепи алюминеевьІй, и короткие юпки в поршней ... Ну что б потребитель чаще приходил за тачкой!
Вадим , они постоянно доробатывают свои моторы , внедряют что то новое и технологичное , думаю этот мотор свои 180 тыс отходит без проблем , а больше турбо и не ходят в наших условиях
@@dismay6069 ага! особенно моторы в тачках 2016 го, уже на 70-100 тыс надо менять порши и гильзовать.. такого не было в 2000х!!
очень часто моторы выходили из строя из за забитых радиаторов охлаждения
@@Karavai13_live Вот опять же все кричат очень частно , но никто не говорит сколько машин продано и какой процент . В 2000х и машин столько одной марки не продавали
Don't present these engines as futuristic technology... They are doomed, the electric motor beats them hands down.
I'd rather ruin the environment than die burning
@@mudargamer There's more than enough oil to go around. Oil naturally "renews" itself. Capped off, dead wells often renew themselves. No one is really sure *where* oil comes from. Old John D. Rockefeller made-up that ridiculous meme "fossil fuel" in an effort to drive up oil's cost framing oil as a "rare-earth" commodity. Oil doesn't come from dead dinosaurs. Oil is as essential to the "world system" as blood is to your body. Those power lines along highways and internet cables strung across the ocean bottoms are the world system's nerves just like the actual nerves strung up and down your body. The day I see a solar powered, Airbus A380 taking off with a full load of passengers & cargo I'll watch for oil's obituary in my local paper. Until then, the speed limit is just a suggestion.

@screaming chivo And you really think that newer engines like this one, fully packed with very complicated technology (GDI, twin-scroll turbocharger, PF, EGR, dozens of sensors) are going to last 400000 miles without any problems, like the good old ultra-rustic V8s? 😂
At work, we have some electric motors that have 30 years and still run almost 24/7...
@@mudargamer Because fossil cars doesn't burn? 😂
@screaming chivo ahahahahahahha. IDIOT. Electric cars are objectively so much more reliable because so much less moving parts. A good electric motor will WAY outlive the very best Korea, Japanese or German ICE engine with no maintenance, because, electric motors have nothing to maintain. If you think electric is not the future, your really not very smart, they are objectively better in every way. Even an idiot like you can understand the simple working of an electric motor but definitely not a ICE engine.
What could go wrong
It looks like how VTEC concept.
The car head lamp look like lexus
Govind Raj no
Make v6 or V8 and I'm in
Still very far behind Freevalve
Who cares? FreeValve is too expensive and inefficient and has questionable reliability to make it popular.
There's nobody driving the car
아니 왜 도대체!!!!!!!!
2.5트림엔 R-MDPS 를 안주나요!!!!!!!!!!!!!
너 무 하 시 네 들 C타입쓰다가 ABS, 차체흔들림, 핸들위험경고등 한번에 팍 세개 다 떠서 핸들 빡빡해지고 난리났는데 쓰고 싶겠습니까!!!! 근데 또 3.0은 내 분수에 감당이 안돼네ㅠㅠㅠㅠㅠㅠㅠㅠ 그냥 버스타야겠다..
Will it burn like the theta engines🤔🤔🤔😁
Only if gm pays another American south employee to sabotage the engine like they did before. Nothing was faulty about those engines except the dumb ass employee in the south that didnt do his or her job properly. Stop being bias.
If it’s reliable. All this new crap is nice when it works. When it’s broken I think simplicity.
