I'm working on the same idea--still on the drawing board--for an International truck six. Using the idea of 3 injectors, one in each intake runner...since the head is where the ports actually "split" for each cylinder. You simply have to make each injector fire EVERY crank revolution, instead of every OTHER crank revolution. On a low-rpm engine like a tractor or some of these old trucks, firing each injector twice as often still shouldn't be too bad on them.
Remember, it takes TWO crankshaft revolutions to make a combustion "cycle" on a 4-cycle engine...so on your 4-cylinder example, you'd be firing one injector every 180 degrees, since it would take 720 degrees--two crankshaft revolutions--to fire all 4 cylinders. At 90 degrees of crankshaft rotation, there should be NO spark OR injector events going on...think about it.
