I am thinking that the transfers will actually be very low and I think that the exhaust is also lower than normal, possibly around 170 deg or even as low as 150 deg and would think the transfers will be around the 110 to 120 deg mark possibly even down to 90 deg duration if the pressure is high enough in the transfer system. It would be depending on the preset pressure of the reeds to activate.
There is also the possibility of it using a combination of spark ignition and the newer HCCI system after the heat in the system allows the HCCI to work.
That way, there is no problem with getting the ignition to keep up with the higher rpm as it becomes compression ignition.
It is my opinion that the very high compression will allow an otherwise too lean a fuel load to be ignited. That would account for the low emissions when tested.
