With the patent filing, they probably are making a jump on the EPA or equivalent agency requirements for allowable emissions, with the double burn, any left over fuel gets a post burn, as you said, replacing needs for maybe EGR valves and or Catalytic Converters. Not to mention how expensive in both waste and materials those CC's are.
The port arrangement will mean it needs forced induction (turbo or supercharger) as it’s very similar to the old Detroit diesel 2 strokes. If it’s only relying on the slight effect through scavenging there won’t be that great a performance gain, just added complexity. In any type of machinery, the simpler the better. This is just less reliability for some possibly dubious gains.
This somewhat makes sense if using forced induction and direct injection where the stoichiometric mix can be managed and unburnt fuel losses avoided - but N/A with port injection... really ?
Nope. Mitsu GDI was first mass production gasoline direct injection - today found in nearly every new car. I had this engine (1.8L) and it truly worked - car was very fuel efficient.
If a hydrogen generator was installed to constantly trickle hydrogen into the engine or a fuel canister it could actually make petrol fuel burning more efficient. You can plug it in at night and it fills up the canister with hydrogen. It could alternate between petrol fuel and hydrogen or a combination of both during driving. Hydrogen actually will clean up your emissions to the point where you don't even need a catalytic converter. And your home could be your fuel station.
@PseudonymAliase I was thinking the same thing but with natural gas. Hydrogen would definitely work. Oxygen would work too, but the volatility isn't practical.
@@bryankotsch hydrogen engines exist volatility is totally practical. The problem is it costs $250 to $350 to fill up your hydrogen canisters and go 300 to 500 miles
@PseudonymAliase We need a more streamlined way to extract hydrogen and oxygen from water. Of course, big oil companies would not be happy. I remember the Bugatti that ran on propane or natural gas as well as gas and achieved the same top speed. Fastest car in the world for a brief period in the 90's.
Using a mix of gasoline and ethanol also give cleaner emissions. My MB190E would not pass the emissions tests here without running 40% ethanol and rest gasoline mix.
While this is amazing tech I think Porsche is better off pursuing E fuels. E fuels would allow you to keep the conventional ICE design while still meeting the absurd environmental regulations.
I guess you know better than all the world class engineers that work at Porsche huh? Go ahead and tell us who you are, genius, so we can scroll down the long list of your achievements sure to be included on your lengthy wikipedia page
I wouldn't say its overcomplicated at all, the tech is pretty basic and resembles similar things in valve tech we've seen through the years (vtec, Mivec). Given there is a difference between the two but both were considered complicated originally and then later made very main stream. The part I don't understand, Porsche are one of the manufactorers that are moving towards electric and Hydrogen powered cars, this tech doesn't seem to fit with that model UNLESS they have plans for this to be primarily a hydrogen powered engine which does change things quite alot.
My 6.0 diesel would like a word with you... 😂 This is a way to get around an EGR system from what I can gather, which is required to meet emissions standards nowadays. My truck is low miles for an '07 (89k miles as of today) and I'm on my 3rd egr valve. And yes I've tried to clean and reuse them. The next thing to change is the EGR cooler but I'll delete it because I don't have to do SMOG tests
It will work but there will be a host of issues with reliability. The gear on the crank will be another source of failure, the secondary injection ports too. I honestly don't see the point of this when Hydrogen and/or electric seems to be the future.
@@watchnocatch171we could just reject the EV mandates and vote out the politicians pushing them. They're not gonna stop using bunker fuel in container ships, so why should we be forced to stop using a much cleaner fuel?
Can't wait for all the armchair engineers to come out of the woodwork and explain to the world how this engine is the worst thing ever made and Porsche's engineers don't know what they're doing, etc.
It's not that it's the 'worst' thing ever made (that title will remain with anything Stellantis makes), but the design makes the engine setup as complicated as that other engine Nissan created a couple years back. Putting more moving parts in an engine will most likely decrease the longevity and/or reliability.
@@TheReal_JG It all depends on the engineering. VTEC or similar variable valve technology also adds more moving parts to the engine, yet we have engines lasting 400k kilometers. Even DOHC is a complication compared to OHC or even push-rods.
only in your dreams. those ware not even fast in race trim. from what i remeber even the aprillia rs and caviga mito were faster. even a suzugki rg500 get's destroyed by almost any modern porsche. do i have as much fun in a modern porsche, as one a small nimble bike. that is a different story ...
Let’s be honest. Electric car sales are up 31%. Only 4% of people who buy an electric car go back to a hybrid or ICE car. VW group profits are down almost 50% and as a result they are in trouble. This won’t make it to full production. China will buy more of Porsche/VW. Begrudgingly ICE is over. Zero friction electric motors. Batteries that can charge from any point of capacity percent to full in 6mins. As someone who loves the sound and feel of a v10 or BMW 6 cylinder. These ICE machines are done, gone, buried.
Quick, put a call in to Porsche. They're gonna be gutted to find out their patented idea isn't going to work as they hope, but it's best they know ASAP. Your expertise will save them a fortune...
This is like a horse-drawn carriage company coming out with new carriage shaft technology in 1908. Like cool idea I'm sure, but 20 years too late, and won't be remotely relevant as the world transitions to EVs.
the 6-stroke used to be known as the "miller cycle" engine, and the concept is certainly not new... iirc it got some newsplay about 15 years ago, and it was certainly not new then... it does aid with cleaner emissions, but lower specific output... no surprise that Porsche is looking at it again... cheers!
@@bujaksha They are kinda right though. How long will it take to make the tech reliable? Because Electric powered and Hydrogen power are starting to become more and more main stream now. If this engine takes 5-10 years of hard R&D then it will be dated by the time it is consumer ready. Unless its a tech they are looking to adapt to hydrogen based engines which im guessing is the plan. How really knows with those Germans though, mad bunch.

unlikely that will reach mass production. No sane person would buy this. Then again most new cars in western world are leases.
And i would assume a pretty hot running engine.
It will likely sound like two engines running out of slightly out of phase with each other.
Probably sounds like an expensive maintence bill as well

Nice work. Nice vid.

Nope.

Can't wait to see what they bring to the road in the future ❤❤❤. Porsche just engineering excellence
Great video
the planetary gears will break like there's no tomorrow, put money on that. those additional air ports will probably also keep getting blocked.
Thank you Porsche for keeping our dreams and futures bright
I'm interested in that bus in the back with the house doors on it.
While this is amazing tech I think Porsche is better off pursuing E fuels. E fuels would allow you to keep the conventional ICE design while still meeting the absurd environmental regulations.
I’m confused! 😂
This combution engine addict sees the silver lining!
New engine is very promising but.. when it breaks.. ouch!
It won't break, it's a Volksw-.... oh....
This will change what cylinder count and arrangement is naturally balanced, right?
So you guys saw What the D4A channel did.
I want to hear it
This was my nickname in freshman year.
This gave some hope to the gearheads.
This feels more like a second channel upload
Those planetary gears are just another costly repair job waiting to happen.
TL;DR porsche wants to implement a new EGR system so that they can meet future emissions standards
Shuttle shout out to TDC. 🤣🤣🤣
I think Mike would shoot all DT videos in a scrapyard if he could...
how do you prevent the oil from sticking on the bottom intake in this engine?
Piston works as valve itself. Just like in 2-stroke.
Why no rotary valve engines?
6-stroke will be available within a few years..
porsche tends to follow through with their engine designs when performance is available..
mind blown
As useful as working on better horse feed 120 or 130 years ago.

Horribly overcomplicated and seems like a way to make it cleaner running? Maintenance costs will rival aircraft.

@@MrWiggz69 Porsche is actually pushing Clean combustion fuel/Bio Fuel over electric. They invested heavily in that area already.

It's maintenance costs can't be worse than EV depreciation or battery replacement. I know which one I'd rather have.
Wouldn't this put more strain on the block
its like EGR inside engine
Was thinking thr same
Its kind of like less complex sleeve valve engine.
Love Porsche ❤❤❤
What manner of sorcery be this?
Neat!
Interesting concept if it actually works.
It will work but there will be a host of issues with reliability. The gear on the crank will be another source of failure, the secondary injection ports too. I honestly don't see the point of this when Hydrogen and/or electric seems to be the future.
More things to break when it goes horribly wrong and it will write off the car
Maybe. Until someone has a better idea, the only alternative might be no somewhat conventional ice at all. So what do you prefer?
Yup, I wonder how much the efficency gains will be offset by nobody wanting to fix them due to cost.
@@watchnocatch171we could just reject the EV mandates and vote out the politicians pushing them. They're not gonna stop using bunker fuel in container ships, so why should we be forced to stop using a much cleaner fuel?
German engineering. How far we reached from the VW Käfer.
So the fuel efficiency will be increased I think.
Nobody told Porsche that fossil fuelled vehicles are history?!
I love the optimism of thinking Porsche are going to have slow ICE vehicles in 2030 being whipped by soccer moms in Kia EV minivans.
Does it work by exploding petrol just like any other internal combustion engine? Yes
Where is that back drop.
Rocket stove principle
Probably will work with electric motors to even power output
So more power but shorter lifespan ?

Over complicating something with marginal benefits. Yes, you proved it can be done. Now, pick something with a better benefits to complexity ratio.
Its not complicated at all the issue is Hydrogen/Electric is the future so this tech all ready seems about 20 years too late.
Porsche has gotten less reliable over the past years, I,m sure this will help with that.
Nice idea...

I wonder how much of the efficency will be offset by the fact many will be scrapped due to cost of fixing them.
