jef, I just started reading this very interesting thread on your engine build. Real nice work you do for sure. I was wondering about the port timing, is it the same as the engine you chose to build your own version of? I guess you may call it a "piston" port engine & not any reed valves. If you can, could you post photos of the rod as you machine it. Thanks Very Much, Capt,n
Hi Captinjohn , it is a piston ported engine (old school)
the porttiming of the new engine is 130° for the exhaust ( was 110° ) , 113° for the intake ( was 100° ) , 100° for the transfers ( was 90° ) , the compression ratio is now 6,7/1 ( was only 5/1 ) , in the future there will be certainly pictures of the rod construction ,right now I can not post any picture , internal server error .You could always go and see at another construction report from me on a Dutch forum , there are pictures between of the rod constructionhttp://www.modelbouwforum.nl/forums/bouwverslagen-vliegen/175091-bouwverslag-2cc-dieselmotor.html
