This would be very interesting if the engine can run on the residual fuel left over in the cylinder after an exhaust stroke. But, dare I say, not impossible. The exhaust valve should be closing somewhere around the 24 degree BTDC point, so, the fuel would just remain in the cylinder throughout the next intake stroke and then fire on the next compression stroke. Granted, the fire is not going to be very hot but the engine could possibly run on it.
