This time not more rpms, just a more refined machine, poducing its power more smoothly. The crank is stabbilised with 2 paralel shafts, which prevent it from twisting = more power. Switches use scotch yoke principle of operation.
This time a small inline engine using the small lego cilynders. It's doing only 2400 rpms, but since it's only 2 cilynders the vibrations are extreme :( I know that those small cilynder engines are capable of much more, but with only 2 cilynders i won't achieve much more (probably). The speed computer is geared down 3:1 for better accuracy.
I abandoned the double cam setup in favor of a pushrod setup. It has much promise. I have to further tweak the opening times, to hopefully get some consistent 1800 rpm numbers out of it.
The engine actually runs at 1540 for a second or two. I still have lots of work to do untill this runs as desired (1600-2000 rpms), but it has come a long way. At the end you can hear the compressor kicking in.
Just a quick test, to see how smooth the new V6 mechanicals work. The pistons have been removed, so i can fix some leakages. I think the mechanical side works pretty smooth.
