Abstract

PURPOSE: To perform a proper fuel injection throughout the operation by consituting a fuel injection nozzle with the first and second cores, each having a different polarity, and a needle, and by injecting a fuel slightly or in a good deal, at the light load operation or at the heavy load operation.
CONSTITUTION: The fixed first core 6 magnetized by the final coil 8, the mobile second core 9 spaced from the first core 6 and magnetized by the second coil 17 and a needle 20 of magnetic material spaced from the second core 9 are disposed in a housing 2 of a fuel injection nozzle. Fuel passage 5, 7, 12, 24, 25 are provided on the axis of each core 6, 9 and the needle 20, said needle 20 opens/closes a valve opening 3 and each core 6, 9 has an opposite polarity. At this load operation the second core 9 abuts on the needle 20 to inject fuel slightly, while at the heavy load operation the whole abuts on the core 6 to inject fuel in a good deal.
