The first thing my mechanic said to me when i was looking for a new car, was NOT to get a car with this belt type. Vendors apparently often dont replace these as they should or take responsibility for failure even under service agreements.

Biggest benefit in the compressor/e-supercharger engine to me is the lack of back pressure. Still until the electric motors are likely water cooled, and batteries are waaaaaay better than they are now, meh.

This was really cool! I wonder if it'd be possible to get the spark with an electronic system rather than trying to create two separate mechanical systems at the same time. For example, using something like an Arduino and a solid state relay to identify when the spark needs to happen and then initiate a spark at that moment using a battery or other power, and just worry about getting a combustion event.

24:40 OMG CHECK IF YOU'RE GETTING SPARK!! 🤦🤦🤦

This is dumb. Its never gonna come to fruitation b/c many nations are banning ICE in favor of electric & other alternitives

18:18 yeah let's revisit that question in 4 years. Besides, are we not already there for passenger vehicles? Taking on nearly 200 miles of range in under 20 mins is pretty acceptable for passenger use, as are ranges of 300 miles, not to mention home fueling. Don't get me wrong - I love the engine this video is talking about - but there's no need to knock BEVs to sell us on this concept when they are rapidly getting better and getting adopted.

20:24 Right off the jump in seeing that you have a magnetic flywheel making the coil spark once per revolution, when you have 6 vane chambers, so it needs to spark 6 times per revolution. Sorry I'm late.

gears are just levers, stacked radially 🤭

Well done.

Chinese EVs make all these obsolete. No maintenance other than suspension. Million mile batteries

Some points: 1. Comparing a free valve engine for a mainstream low budget car to sporty engine 8 years in the future to disprove the original claims is unfair. 2. You don't mention the square profile that's unachievable with a camshaft setup.

Why is air density different in a diverging section of a pipe if the whole pipe is sitting at essentially the same height above sea level? If the air was less dense in a wider pipe, there would be a current of air flowing towards the lower density region.

Bravo 👍🏻 Momci

Somehow your Texas accent mixed with your English speaking accent just sounds like 2 different people talking.

Don’t believe the hype this is a micro v8 engine! 8 cylinders means 8 possible means of problems, don’t fall for it folks!

Honda...we dont copy anyone...ha ha ha ha

The NS200 engine that is only 200cc makes 24HP.

So no friction in this universe?💀so it’s not going to break?

What do you think of the Hond scl500?

There are too many jeeps driving around telling everyone they dont understand also.

would take that car any day over a american car xD

Amazing!!! Great explanation!

why would you do this??? Just curious. new to this channel.

Is there any difference in sound between pre-ignition and knock?

As a mechanical enginner, specialized in R&D: nothing works at the first attempt. The first try should be simpler and just a prove of concept, make it work as a compressor first, then try to spark the fue, and then run it. modularity is the easier way in my experience

It's that think I look into at the optometrist office.

Torque = force. Horsepower = rate of work. Torque is how much force the engine can deliver at the crank. Horsepower is how much work that engine can accomplish over a period of time. Lifting 500# is impressive but if you can’t do it very often then someone that can lift 250# many times in a time period will likely generate more actual work.

the ratchet sound is also coming from the "runner gears" right?

This is a sensational explanation - brilliantly done.

You're too harsh on your audience and on yourself

To work as well, the vertical distance of the rotary valve will have to match the circumference of the a standard vale:)

You are totally right. My girlfriend has a Citroen with the Puretech engine and as you guessed.... it failed at 137.000 km, leading to a catastrophic engine failure, which led to an engine swap worth around 6000 euros. Of course, paid by my girlfriend since the dealer organisation refused any guarantee because it was not proven she used the exact right grade oil. She actually did, but it was not provided by the official dealer but by a multi-brand service centre and the car had a clean service sheet.

what type of engine is this? wankel sibling?

I would think that would be noisy. With the planet gear.

I would be happy to test it in my ultralight airplane

Who else just discovered the most interesting part of the this video....honda made a V3 2 stroke... LIKE WHAT! i have to find one of these now, long live 2 strokes!

Imagine literally admitting that their father is a snake and they come from him... those papists are honest at least

many years before 2050 engines running on fossil fuels will be banned. Unless this engine is electric, it’s incredibly inefficient and already a relic of the past.

What compresses the vane spring when it passes over the exhaust and intake ports?

Wet belts are indeed working better on diesel engines but on petrol engines they are a disaster mainly because of the petrol in the oil when the engine is cold or simply worn out, alongside a lot higher oiltemp.of turbo petrol engine. I did not know that the 1.8 tdci had have a wet belt. On that engine the belt caused no failures. But another maker namely Honda are the next that want to loose customers with its new 1.0 3 cyl turbo petrol with wet belt.

I believe you are from Serbia? So you say *Poršé* - which is obviously the one and only proper way to say it :)

Something that was never brought up in this video, but plays a huge part is government regulation. Cars will be more reliable better engineered if the government didn’t stick its fingers in every part of how vehicles work.

That's a very poor comparison with the infernal combustion engine: the one you had there is far more powerful than that Stirling engine. If you ran a Stirling of comparable power you would have much the same problem with combustion gases.

if you could curve the vein as it extends outward you could get a little more surface area. The vein itself is... kinda odd. seems hard to work around. Maybe if the vein had a dual track that was connected to the axel to spin with it, one on each side, you might be able to seal that and keep that cleaner, vented maybe. track circle above, track circle below

They are not identical,one is red one is yellow

both pistons start moving inwards before the inlet is closed, so a bit of air is being pushed out through it :/

Example BMW M4’s have a hard time keeping up with tuned diesel F350’s

an ICE engine is not the ultimate engine lol

0:55 It is obvious that he whispered
