the compression ratio : About 18/1
Zephyrin !
details : I will take some pictures : but not now because I have run out of patience with this engine , there is so much trial and error , adjusts and changes .... with pump , injector , valve.
Roger B !
"I recognise the black sludge from the exhaust " : I used kerosene in that video
That video is not how the engine runs the best , Because I have done a lot of adjusts , maybe more than 50 times adjusts and runs , I want to know if the engine can run ... and how does it run . ..as well as I want to know more about pump, injector, valve, pump and injector can run for a long time , i want to know what fuel it can run with.... so that ,i don't have the patience to put it in the best condition, and i think that video enough to prove that the engine is running so I made a video showing how you see it run

Trial and error is how i want to know more about it .
