You will find it usually in diesel systems. This type of injection provides engineers with better insight on the cylinder combustion process.

3) Sequential Port Fuel Injection – This type is also known as sequential fuel injection, multi-port injection, or timed injection. It makes use of various injectors, which spray fuel in clusters or simultaneously. When the engine is idle, the fuel would be able to stay on the port for up to 150 milliseconds.
