INTERNAL COMBUSTION ENGINE GASOLINE INJECTION SYSTEM

摘要

The invention relates to a gasoline injection system for an internal combustion engine. A control stop for a shuttle-type metering pump is responsive to a cam follower movable by a diaphragm. The diaphragm is in turn responsive to the pressure drop across the engine intake throttle. An airflow control device is carried in the intake, upstream of the throttle. The control device is operable by an element sensitive to engine temperature to reduce the pressure drop and thereby increase fuel supply at low temperatures. A cam track engaged by the cam follower is energizable during engine starting to further increase the fuel supply.
