 Another question about fuel, rotary are very fuel versatile and not too
 octane sensitive,but most people use mogas. I assume it must be regular,
 in Calif. you do not even have access to the highest octane premium fuel
 now.  What changes/adjustments have to be made to use other fuel, such
 as diesel, jet A, or anything else flammable.
 Compressed gas fuel I think are too difficult for aviation use for now.
 Can the other fuel be mixed with gasoline?? A straight diet of diesel
 may free the owner from mixing oil in the fuel since diesel have
 lubricating properties.

 They can be made to run on diesel but not compression ignition so far.
 Therefore there is no improvement in BSFC.

 The current geometry does not allow the necessary high compression ratio.

Hi  Paul.     Does  that  mean  you  can  refuel  with  diesel  when  you
run  out  of  gasoline  ?     Or  mix  the  two ?       Ben


You are also unlikely to get it run without high pressure direct injection.
