ABSTRACT:
A fuel injection system for supercharged internal combustion engines is proposed, which serves to meter a quantity of fuel adapted to the quantity of air aspirated by the engine and also serves to regulate the fuel-air mixture in accordance with operating characteristics of the engine. The fuel injection system includes an air flow rate member, the restoring force of which is generated by means of pressure fluid in a control pressure line. The pressure of the pressure fluid in the control pressure line is variable in accordance with at least one pressure control valve, by means of which the pressure in the control line and thus the restoring force exerted upon the air flow rate member, which actuates a control slide of a metering and distribution valve assembly, can be reduced when the intake tube pressure downstream of a compressor increases. The result is that an undesirable leaning down of the fuel-air mixture caused by the error in air density can be corrected.
