The nozzle itself is a normally closed valve (normally closed valve means that the valve remains closed when there is no input control signal;And normally open valve is when there is no input control signal, the valve has been in the open state), by a valve needle movement up and down to control the valve open and close.When the ECU commands fuel injection, its voltage signals send an electric current through a coil in the nozzle, creating a magnetic field that pulls up the needle and opens the valve so that the fuel can escape the nozzle.The advantage of jet fuel supply is that the fuel supply is very controlled, so that the engine can have the correct air fuel ratio in any condition, not only to keep the engine running smoothly, but also to meet environmental regulations.
