Curious about an Indian Petter Type of Engine

[SevenMaxTriad]

While on my continual search for more and more information about Petters, I saw some videos of "Petter" engines I have never seen before.  Any of you folks know what make and model these engines are based off of?  Are they even Petters in the first place?  I can't seem to find any other information about them other than the very ambiguous titles on almost all the related videos.

Hi,  I have read that the Chinese single flywheel engines (Changfa S195 etc) are copies of the old Yanmars (TS130 etc.), and my guess is that that is what these engines are.

Whether they are made in China, Pakistan or elsewhere, I can't say, but they don't look like Petters to me.

The S195 is a project by one of our members on this site, and my hat is off to him for a job well done.
