I think you mean "multi port". Multi port fuel injection means 1 injector for each cylinder as opposed to there being 1 or 2 injectors inside the throttle body

What does single point injecton mean in cars?

A vehicle with "single point injection" has one fuel injector injecting fuel for all cylinders, regardless as to how many cylinders the engine actually has. More modern vehicles are "Multi-point Injection" which generally means they have one injector per cylinder. In these cases each injector generally injects fuel for a specific cylinder. Hence a 4cyl engine would have 4 injectors, an 8 cyl engine 8, and so on. A single point system is cheaper to manufacture (less wiring, fewer injectors, etc), but generally is slightly less efficient than a multipoint system, hence why more modern cars are multi-point injection.
