Alternatively, electrically controlled "valves" could be utilised on a more conventional head...and if the valves opened / shut normally, but could be extended INTO the cylinder, to increase compression at the desired part of each scycle..(Making the valves a solid tube to take up volume..maybe twisting open / closed to vary between a solid tube and a fuel delivery / exit path)
Just some random thoughts to help with overcoming the requirement for 4 x truck springs being inside a 4" cylinder bore.. (Havent invented a Tardus as yet...sorry..)...

Very interesting link. Looks like a workable improvement.
Also great idea from you, I think?
Increase compression ratio after TDC with the valves to burn fuel better and get more power to wheels.
Hi Cajunfj40
I love Ecomodder and mean no harm. I know it is difficult to have threads that doesn't drift, just had a suggestion. Things like in the link above IMHO will bring the gains I'm hoping for. After that type of mechanical changes we can start improving with electronics, etc.
