ELECTROMAGNETIC INJECTOR FOR INTERNAL COMBUSTION ENGINE Russian patent published in 1999 - IPC

FIELD: manufacture of internal combustion engines, specifically, fuel-injecting devices with electron control over gasoline engine. SUBSTANCE: electromagnetic injector has body that houses atomizer and electromagnetic coil. Core attached to body and armature pressed on to tail part of shut-off needle of atomizer are placed inside coil and separated by clearance. Travel of needle is limited by resting of its butt against spacer placed between bearing butt of atomizer and body. Butt of shut-off needle is made flush with bearing butt of atomizer. Length of travel of shut-off needle is limited by installation of distance piece of corresponding thickness between spacer and bearing butt of atomizer. EFFECT: high adaptability of electromagnetic injector to manufacture, high precision of setting of value of travel of shut-off needle of atomizer and high functional characteristics of proposed injector.
