I think you're talking about "you", not "us", but be realistic and listen to us who can provide the answers to what you need to know based on our knowledge and experience.
I'm always welcome to comment, everyone. Do not forget that you made it work with the help of us who guided you to make glow plug engine, model diesel engine with compression screw and the 4 cylinder 4 stroke engine with good results and these model engines ran so well.
I learn and get help from so many people , From masters to those who have never done engines , from forums , facebook , youtube , google... , and I am always grateful for the comments contribute
back problem : 0.03 mm stroke
The oil volume in the cylinder has a diameter of 2mm with a stroke of 0.03 mm
V = 3.14.r.r.h = 3.14 x 1 x1 x 0.03 = 0.0942 mm3
this can be achieved (??) when the lobe surface finish, the oil loss between the cylinder and the piston, the perfection of shaft, ..... is 0.0000mm , eliminating the vibration engine running.....
Because all of that will affect 0.03 mm of piston stroke
Watch from the 28th minute of the video, you can see the piston stroke - that is probably the only video where i can see the piston stroke
and I'm sure it's not 0.03 mm . stroke
