Abstract
A stem of a poppet valve of a fuel injection nozzle has a plurality of first injection ports and a plurality of second injection ports formed in an area in the vicinity of a valve portion of the poppet valve. One open end of the first injection ports are spacedly circumferentially aligned. One open end of the second injection ports are likewise spacedly circumferentially aligned. The one open end of the first injection ports are located downwardly of the one end of the second injection ports. The one open end of the first and second injection ports are axially aligned. When an engine is revolving at a low speed, fuel is injected from only the first injection ports, and when the engine is revolving at a high speed, fuel is injected from the first and second injection ports.
