- | The fuel injectors are electrical solenoids (switch valves for liquid) that allow the flow of pressurized fuel from the electric fuel pump. The injectors spray fuel (like a hose nozzle) into the intake manifold air tract.

The injectors spray fuel (like a hose nozzle) into the intake manifold air tract. |
The injection time (therefore, fuel amount) is a matter of how long (in milliseconds) the injector solenoid is active. This is a very small time period. | The injection time (therefore, fuel amount) is a matter of how long (in milliseconds) the injector solenoid is active. This is a very small time period. | ||
