Webb14 maj 2024 · The period of time is known as the injector "pulse width" and is measured in milliseconds. (1/1000 of a second) They are in the intake manifold near each cylinder head. Electric Fuel Pump - A 12-volt high-pressure fuel pump, (located in the fuel tank) supplies fuel under pressure to the fuel rail on the intake manifold. Webb21 aug. 2024 · Because on a modern electronic injection injection system there is one injector pulse per firing stroke increased fuel flow for higher RPM isn't a major factor in injector pulse length. You can observe the injector pulse length increasing if you add load at idle speed by switching on electrical loads and the AC.
