This technology is used in Gasoline/petrol Engines. Initially carburetors were replaced by Single Point Fuel Injection (SPFi) that involves only one injector for all cylinders which often led to ...

SPDI (Single-Point Direct Injection): In this system, fuel is injected into the intake manifold just before the intake valves. It is used to improve fuel atomization and combustion efficiency compared ...

Single-point fuel injection is an earlier system that uses one or two injectors in the throttle body to spray fuel into an intake manifold shared by all cylinders.
