It was mentioned that the problem with a '747 and a 4cyl engine
with 1 injector: was that the one injector wasn't firing often enough.
That the one injector was firing every other plug firing. This was the
cause of the backfiring and herky-jerky motion.

When looking at the common TBI V8, the injector firing intervals
per spark plug firing is the same. Each injector fires every other
spark plug firing. The V8 then divides the two injectors between two
banks of 4 cylinders. Same as 1 injector on a 4 cylinder engine.

This is by the design of the intake manifold. The manifold is split
with each half feeding 4 cylinders. Each half is feed by 1 injector.

No difference in the fuel feed per injector between the 4 cylinder
and 8 cylinder engine.
