Your English is more than fine, no need to apologize. Thanks for your time spent making this well done video, keep it up. Ignore non constructive criticism, always be open to different ideas or opinions but at the end of the day do you my dude.

I  got to work with Napier Deltic Engines during my Navy Service . Astonishing Power for the size of them . And the TS3 is legendary .

@TheSilverShadow17

The Opposed Piston design is the Internal Combustion Engine in it's ultimate form and expression. As well as being the most efficient design by far, because it doesn't involve the use of valves or heads, or camshafts which makes it MUCH simpler in design and can be roughly half if not a quarter of the size of a traditional layout, but with significantly greater thermal efficiency to boot.

@ivanyurkinov

nice presentation, well narrated great graphical animations! thanks for the interest and time to put this together.

@gregwarner3753

I am fascinated watching the illustrations of the Napier Deltic engine mechanism. Fascinating way of achieving diesel compression ratios without the extreme piston accelerations associated with long strokes. This configuration seems ideal foe stationary power plant use at lower cost then oil/gas turbines.

@Tonedog88

The Closed Caption function is more inaccurate than your English.  I'm glad you're effectively bilingual because the captioning was comical.  I'd never heard of opposed piston engines.  It's always a great video when I learn something new.  Thanks much!

@ridefast0

I was on a UK train many years ago, when it accelerated I had to hold my cup of tea to stop it sliding off the table. Yes, that was a Deltic locomotive, much loved and much missed by its fans.

@cyrus7210

I've never experienced the opposed piston engine in any form. It's got potentially more various forms than I can grasp. This kind of mechanical voodoo piques my interest and let me tell 'ya...start looking into this one and it branches of in so many directions it's amazing. Hey... your speech across this video is not to be apologized for. Its got a unique pattern to it, the timing, pronunciation, structure used etc.. I find it easy to listen to and comprehend. Lyrical is a word that's comes to mind. Dude I've lived my life in the South so I've heard beau coups of interpretations and find yours to be one of them,so no apologies necessary. Now my cousin Brittle,him and the rest of them Clakhits, now there is an accent to grasp. Couldn't tell if he was telling us about his boat trailer breaking or the new puppies they have, either way,we got the mailbox put upstairs and he's happy.

@billdennis2993

Thx for an informative video, while surving in USN in early 70's was stationed on Coronado Island and had the pleasure of hearing the 3500 hp Napier Deltica mounted in the  "Nasty" PTFs they sounded like turbine engines with the exhaust pulses of 18 cyl in each revolution. Your compression ratio example is incorrect shoukd be expressed as 15:1 which is the minimum for a "Diesel" compression ignition. enginea.

@MarttiSuomivuori

Man, never mind your second-language English. You graphics are great and your presentation clear and factual. My respects.

@jimmykreutz6087

Thank you for advising us watchers of the language advisory, much appreciation, real class!

@ignasanchezl

A few things are wrong with the video, nothing super notable exept that this 2 stroke does not burn oil, just like other blown 2 stroke diesels.

@pashakdescilly7517

A French company called Gobron-Brillié  made two-cylinder opposed piston engines from 1898 to 1922.  For quite a while, they were among the more powerful engines available.  The design is very unusual, having two cylinders and a yoke driven by an extra pair of crank throws to operate the opposing pistons.  There's a Wikipedia page on it.

@SJR_Media_Group

Great introduction to Opposed Engines...

I have been working on several Opposed Engine designs. One is a 180 degree flat opposed with 2 crankshafts and 1 common head. The technology is in the head and large gains are possible. Both are 4 stroke Gas but have also been working on a 2 stroke gas engine as well.Tthe other is a 120 degree inverted V using a common head. 180 degree makes a wide but low engine. 90 degree makes a narrow but taller engine. 120 degree is  good trade off for width and height. 

Common head has variable timing, duration, and overlap using camless technology. It also has variable combustion chamber volume so most efficient compression ratio is always used. The 2 stroke uses mechanical supercharger forced induction. It also uses mechanical exhaust scavenge pump. We are not using bottom port and long piston. That works great in a low RPM engine for ships or locomotives. We are using very traditional 4 valves, 2 spark plugs, fuel injection. We have squeezed 720 degrees of 4 stroke into 360 degree of 2 stroke. 

We want to move from design to prototypes to validate concepts.

@whydahell3816

Nice work. Good content and your English is as good as most Americans!

@sparty94

good video, the graphics are excellent. your english is fine btw, i had no problem understanding you.👍

@mrkiplingreallywasanexceed8311

Hello sweetie - I congratulate you on doing a video on such a technical topic in a language which is not your own. It was fairly intelligible although your use of excellent animations of cutaway engine sections was a very visual aid to understanding and helped smooth over any gaps where perhaps one or two trip ups may have slightly interrupted the flow! However I would be very happy to suggest some changes to both the wording of your script and provide some clues on the pronunciation of a few specific words which might  help both how to say them more clearly  - but also where the stress or accent should be placed in longer words  - and even how to make the "rhythm" more natural which would also further tweak and refine how comprehensible your explanation is. You can reach me here in the comments initially and perhaps we could get into the detail via email. I have no financial or other hidden interest other than I have time on my hands, I am a competent authority (certainly at this level) and you asked for help in the first few seconds of the clip which I am happy to give you....

@crabby7668

Commer and dodge used to supply trucks with opposed diesels in UK in the 60s. You could tell them a mile away from their distinctive sounds.

@TIJoe-te9qu

I can understand your English, and the animations are great. You probably also know about the Commer British opposed three that had one crank and rocker arms.

@seagie382

I really like that you chose to narrate this video, I couldn't possible sit through a text to speech video.
Though, I wish someone would upload good english captions, the autogenerate is unintelligible.
