FUEL DELIVERY SYSTEMS FOR INTERNAL COMBUSTION ENGINES

摘要

Airflow in an outlet pipe (1) of an engine is assessed by the position of an airflow measuring member (2) movable in a divergent portion (7) of the inlet pipe (2) against the action of a spring. Movement of the member (2) causes corresponding angular movement of a cam (9) engaging a cam follower (11) controlling the position of a fuel metering member (19) controlling fuel flow to fuel delivery nozzles (65). A pressure regulator (71) is provided for controlling the fuel pressure drop across the fuel metering member (19) so as to be proportional to the air pressure drop across the airflow measuring member (2).
