Hi All !
I just tested :
the pressure is quite high, I can't seal the injector
It seems to be pretty good
I had to make new piston and lap cylinder , they weren't so good
Hi Alex, first, I am NOT a diesel expert, just had a bit of training 50-plus years ago, and a bit of modern train while I was the emissions Engineer at a car plant.In practice the spray pattern is not allways conical, it is sometimes shaped using different sized holes and angles, more so laterly trying to satisfy emissions, again a reason for going to electronic control, however if you do manage to get a good spray of fuel at the right time and pressure with no drip you will have achieved something that many have not or would not attempt, me included, I had enough problems with all the right gear. I'm ashamed to say that if we did have some high smoke pumps and the destination didn't have tight emission control they would probably go depending upon how busy we were. Injection pipes also get very hot and are noisy, why I don't know.
How are you planning to control the amount of fuel delivered per injection?
Your injector spray looks good but time will tell how it acts under the pressure of compression?
A very fine mist ignites well from the compression heat and has little smoke. Bigger droplets don't ignite as well and produce allot of smoke.
Keep up the good work.
Cheers

I plan to control the amount of oil entering the engine with the cam lobe height and the oil pressure adjustment bolt .
A project of which I do not know the outcome !
Hi All !
I just redid the new cylinder, it sprays a little better .

I think the danger is what happens if your engine works better (makes more power) than you expected. Without a governor it could accelerate to such high RPM that it throws a rod or suffers some other catastrophic failure.Mechanicboy, Willyb !
Thanks !
If I just need the engine to run - I don't need adjust the speed , because I don't know if the pump and the injector are fine , so do I need that part ?
