The fuel injection system is intended to provide the engine with better and more economic performance under all operating conditions, providing a more accurate fuel dosage with faster response.
It adjusts the pressure in the entire fuel line, from the outlet of the pump to the injection nozzles.
The Diaphragm is a pressure regulator used in single-point injection systems (it has only 1 injection nozzle) located at the throttle body.
