Abstract
Disclosed herein is an electromagnetic fuel injector comprising a fuel outlet opening formed at the front portion of the slide member of the valve body, an annular fuel passage leading from the fuel outlet opening to the valve seat and an annular restricted portion provided at the annular fuel passage. The fuel injector of the invention may compensate decrease in the amount of fuel flow because of decrease in the specific weight of fuel and creation of fuel vapor at the fuel injection nozzle in association with increase in fuel temperature, and may supply an engine with fuel mixture having stable air-fuel ratio to purify exhaust gas during engine operation at high temperatures.
