The fuel flow to the injectors is metered mechanically in the fuel distributor by a linkage from the airflow meter. Additionally, it is fine-tuned electrically via the electro-hydraulic actuator valve (mounted on the side), which is controlled by the ECU depending on various inputs - primarily the lambda sensor (O2 sensor).

Note too each injector has a mechanical pressure-actuated check valve. Dropping the fuel pressure to them cuts off the fuel flow completely.
