The fuel supply system must make available to the fuel injectors an adequate quantity of filtered fuel from the fuel tank, and at an adequate pressure (injection pressure), in all operating conditions.

Function

The fuel pump (M3) draws the fuel out of the fuel tank (75) and pumps it through the fuel filter with integrated diaphragm pressure regulator (55/1) to the injectors connected to the fuel rail (17) (single-line system).

The fuel pressure is controlled to approx. 3.7 to 4.1 bar by the diaphragm pressure regulator. The fuel pressure is controlled independently of the intake manifold pressure. When the throttle is depressed sharply, fuel supply is assured by means of the acceleration enrichment. The large-volume fuel rail prevents the formation of vapor bubbles.

Excess delivered fuel flows back unpressurized from the diaphragm pressure regulator in the fuel filter to the fuel tank (75).

Air is admitted to the diaphragm pressure regulator in the fuel filter by means of a hose line to the fuel evaporation control system.

The fuel injectors operated by the ME-SFI control unit, inject the fuel as a finely atomized spray into the intake passage.
