Paul,
  I think I got the picture of peripheral port housing off your site. The
two right housings were regular housings that were ported, what are the two
smaller ports above the intake and do you have more information on
peripheral porting?

That was an unsuccessful attempt to inject fuel directly into
the rotor housing. The fuel needs time to atomize for good burning
and injecting it directly into the rotor housing at low pressure
does not work very well. This differs greatly from high pressure
direct injection as that causes the fuel to atomize well.
Some of the latest diesel injectors are up to
about 30,000 psi or above.

Peripheral porting generally improves the volumetric efficiency
and consequently the power available 10 to 20%. Idle smoothness
is a problem for car applications.
