Sorry to butt into this thread with this, especially since I can’t remeber if I asked this question somewhere before.
Google gives me nothing.
For short lived, but possibly crazy good scavenging, would it be possible to put pulse jet style reed valves in the head of the piston?
- It wouldn’t care about transfer timing; the valves would always open and close at optimal pressure differences.
- It would cool the piston and flow oil past the bearings better.
- It would allow 360* exhaust porting. Filling from the center, pushing exhaust out.
I imaging it would be hard to get a good seal (if possible at all) and the lifespan would be very short.
I dont have the equipment to try it. Clearly some of y’all do. I probably could google the combustion chamber temp and pressure of a pulse jet and compare it to 2T engine. Just fishing for an opinion if this idea deserves to be on my “back burner” or scrapped as a wild fantasy.
This pic is of the pulse jet reeds. My idea would invert them so the petals point toward the center. What do you think?
