The only thing to solve this is using rotating valves. Once I have seen an engine using 2 rotating tubes above the cylinder, one with an hole to the cylinder to let the fuel through the tube in and one tube with a hole conected to the exhaust.
Yup. I've seen all the aircraft, motorcycle, and automotive non-poppet valve designs (that I can find online), and all the RC non-poppet valve 4 stroke designs. What I'm drawing is much different than anything I've seen before. The only reciprocating thing in my engine will be the piston.
I've had this design kicking around in my brain for years but I assumed it wouldn't work, or that I would never have the means to make one. Now that I'm seeing it in 3 dimensions, I know it will very likely work and that it isn't outside my abilities and means to at least make some prototypes.
