So it’s like Vtec but biased towards economy rather than power? How positively clever and bland at the same time.
I guess, but VTEC is also somewhat biased towards economy. The first cam profile is for economy and the second for power.
You just discovered the truth by implying someone else’s ignorance. What a wonderful day on Earth. Yes, vtec is about solid mid-range (which it actually never had) for ECONOMY DRIVING while being able to extend the rev-range beyond the touque focused cam profile for more power at high revvs.
So basically VW gets VTEC. Nothing new here.
And let me guess, there’s a sneaky hidden third cam profile which is only switched to during fuel economy tests…
Lol you got me!
Lol
Budackgate intensifies
So haha yeah this giant of a manufacturer that VW is, has mildly modified atkinson cycle. Meanwhile Mazda has revolutionized the ignition of the mixture with just a tiny fragment of the budget and market share.
Yep, this really doesn’t sound like it’ll change much at all. But the car will probably sell well because “REVOLUTIONARY NEW ENGINE CYCLE THAT IMPROVES MPG!!!!!”
And Koenigsegg is developing a Freevalve system which will allow this kind of thing to be controlled far more closely, and they’ve probably produced fewer cars in their lifetime than VW produce in an hour.
Actually that’s how it is, the smaller companies r innovative while the large companies are generally more conservative, if a small company’s idea takes off then they adopt the idea too and sometimes they buy the smaller company too.
And then there are electric cars, which are much more simple and don’t need to be fettled with as much. Also may have better range and carbon emissions. But there are drawbacks too
Variable valve timing with a fancier name
compression brings efficiency, MAKE a smaller engine, and use it FULLY and it will be MORE efficient than this thing.
NO, bigger engine- better tunability.
Not necessarily. A lot of small, heavily-boosted engines have to run rich fuel:air ratios to cool the engine.
Emission scandal incoming!! 😂
What are the advantages of the Budack over the Atkinson, if any?
Seems to me that the Budack reduces the amount of intake air which reduces the amount of fuel being “sucked up” whereas the Atkinson throws some of the usable mixture “away” into the exhaust. In my opinion the basic principle is the same but Budack eliminates the one inefficiency Atkinsons introduces.
Just my 2 cents as a mech engineer. Any combustion specialized engineer want to weigh in?
“Budack” will be the sound it makes when it breaks down 😂
