This means, that for small pulsewidths, the fuel actually is fully injected on the closed valve. This allows for better atomization and a cooler intake valve. Only when load goes up does it get to spraying into the open vavle
Everything I read said that the injector fires right before the intake valves opens.

I am pretty sure.
