A lot to break down in that video, several of these I have owned and become very intimate with, and funny how I can spot the video clips taken from several mainline YouTubers videos and well known engine builders. A shame the list is wrong in number one though. I haven’t personally witnessed over a dozen 12 valve Cummins engines break a million miles, 2 that broke 2 million miles, and one that came through the wrecking yard and was bought not dismantled that was over 3 million. The owner dropped it off for a rotted out cab, the junk yard owner bought it and had me put a used cab on it and drove it home gave it to his grandson

All of our engines, in fact, still use the energy of the explosion. But we can also use compression energy.
17 years ago, when I was working as an electronics engineer at the experimental plant of the Scientific Research Institute in Donetsk, the inventor Vladimir Kashcheev came to the office of the deputy director of the plant for science (my good comrade). He said that he had made an engine that burns hydrogen and oxygen, not to expand them, as in conventional engines, but to create a vacuum inside the cylinder. The movement of the piston from the bottom dead center upwards creates atmospheric pressure. One of the problems that he had to solve was the freezing of water vapor on the walls of the cylinder.
Here I found a description of this engine and the inventor’s contacts.
However, at that time Vladimir Kashcheev came by his other invention. He needed to make a mold to produce the second half of his glass jar lid. Apparently, solving the problems of disposable caps for preservation would still feed a person better than a fundamentally new type of internal combustion engine…
Although I may have missed something during this time. And such engines already exist in other parts of the world.

It looks like Porsche has a 6 stroke engine. it has an extra power and exhaust stroke. The ring geat it uses looks like it would be prone to failure, so it just looks like hype but that might just be me.

You may be right, but this will have to be determined in everyday use, over a long period of time, and in many conditions. I have seen too many things succeed that I didn’t think were going to, based on my farm experience. I’m a mechanical engineer. I have worked with pressure vessels and piping systems, foundry, turbo charger development. ‘Truth is stranger than fiction’.

Ditto.
Life is stranger then imaginations.
I am just not sure they are going to make it an actual product. It seems like I saw something like this before.

That’s true. When I was a kid, I read every Popular Science magazine I could get my hands on. There were an awful lot of engines, and everything else, that were going to change the world. I think it’s also true that Fiction can be stranger than Truth 
Working at a university, I learned that some folks can’t tell the difference between the two. Or won’t.

LoL. So glad to be out of that. My parents were professors at the University of Vermont. I escaped by working on a dairy farm. Reality is beautiful!

It is a matter of approach . . .
A believer is a Believer because belief in something is what gives it credence in their lives and useage.
The other approach is also an extreme . . .
it is not an accepted valid working Truth until it can be math’ed-out, rationalized and explained. So not a Truth; it does not exist to them. Not accounted for.
Until it rears up and whaps’ you in the head. Bites you in the ass. Opps.
A practicalist person just accept things as they are.
On the woo-woo six cycle engine as an internal combustion engine there will be internal combustion blow by gasses. If the internal engine negative pressures are still used as a system vapors capture and burn up recycling them; there will be continuous internal acids building up. Etching and eating away materials.
Connecting rod and/or crankshaft changing variable compression ratio LAB Testing engines work O.K. Low hours of usage with lots of helper maintences.
NOT so ok when in continuous thousands of hours usage as NISSAN is doing now on production general use engines.
Modern Honda trying to create a long life true Atkins cycle internal multi-link engine never could get the rubbing points wear down to their proven hours-in-service life standards.
Many others have trashed their once better engine life’s reputations by adding internal idealizing complexities exposed to harsh internal wearing. Wanting to Believe in better.

I did too. And I read a bunch of back issues as well. What I figured out is some of the stuff, they were saying was new, took a long time to hit the mainstream. If it was actually successful, the technology was 5-20+ years ahead of any commercial product.
Most of it is oil is a limited resource. some of it is performance and some of it is environmental, but even the environmental laws are mostly because oil is a limited resource.

I think it was probably in the 70’s that there was an article on one of those popular science/mechanics magazines about a proposed commercially built home power plant using a Fiat engine and using the cooling liquid as a heating source. Ran on the homes natural gas supply. I must have dreamed it because I have tried to find the article on the web to no avail.

You might be nuts but your memory still intact. 
I think this is what you saw, and I think it made it into pop sci.

Thanks for the affirmation Sean. Doesn’t prove my memory is intact. Can’t find the freakin torque wrench I used last week.

It might just mean you need to clean. It is how I have to find stuff if things get too messy because of starting projects and getting interrupted by something else. Too many cycles, I clean until I find it.
