Abstract
Multiple injection holes are formed in an injection hole plate. Each injection hole penetrates the injection hole plate. The injection hole is formed with an inlet side opening and an outlet side opening. The outlet side opening is formed in the shape of a flattened rectangle having a major axis and a minor axis. Therefore, the fuel flowing into the injection hole through the inlet side opening is injected in the shape of a film from the outlet side opening. Thus, liquid film splitting is promoted, so atomization of the fuel is promoted. Since the multiple injection holes are formed in the injection hole plate, the shape of a great fuel spray, which is formed by combining fuel sprays injected from the respective injection holes, can be adjusted easily.
