mode where you injected it at just the right time to cause ignition
by the red hot exhaust valve.

So, for me this begs the following question.  Have any of the rotary crowd
made an attempt at setting up a stock 12a or 13b as a diesel?  I think it
would be interesting to try.  Maybe that would be a good use for my $50 13b
core.

Unfortunately the rotor combustion chamber shape does not lend itself to the
high compression required of a diesel. The RR version used in effect two
Wankels working together to generate the high compression required which
defeated the compact and light weight advantages of the Wankel in the first place.

That is not to say it cannot be made to run on diesel fuel however.

What about kerosene?  Can the wankel operate on kerosene by
either direct injection or otto mode?

Dennis.

Direct injection but the guys at Diamond Engines say it is not as easy
as it looks.
