<P>PROBLEM TO BE SOLVED: To promote atomization of fuel injected from a fuel injection valve with a simple configuration. <P>SOLUTION: The fuel injection valve 1 includes a partition wall member 4 disposed to surround a tip of a fuel injection valve body 2. The partition wall member 4 forms a space 5 between the tip of fuel injection valve body 2 and itself. In addition, a spray jetting hole 6 for jetting fuel spray injected from an injection hole of the fuel injection valve body 2 is formed on the partition wall member 4. Furthermore, on the partition wall member 4, a gas introducing hole 7 is formed which introduces surrounding gas to the space 5 formed between the tip of fuel injection valve body 2 and the partition wall member 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
