[Land-speed] How About - - No Cam at all?

[Bryan Savage]

I saw a comment on the SAE site several years ago about a single 
cylinder lab
motor used in a feasibility study that had solenoid controlled valves. 
Also a comment
about one using hydraulic cylinders for valve control. Looked ideal for 
a diesel because
at low power settings just enough air can be let into the cylinder to 
support combustion
without knocking. A quiet diesel ??.
