We'll be back in time a bit, for the first project ...
Here with a sketched diagram in cylinders. the basic standard norm poped by the timing.
You can see a huge difference in capacity volume and its asymmetry ..
Adding well-done gasodynamic phenomena, the volume of one cylinder can even be 700 ccm of really sucked air, with a basic piston of 300 ccm.
Well, it's a little not surprising to receive this 200 hp at 5000 rpm with 1 liter of basic capacity ..
But of course I understand that my experience and knowledge is not needed for anyone ... You can start from the very beginning and ... lose a few years to get what I already know ...
