Fuel injection device.

摘要

A fuel injection device in which a fuel injection pump (100) is connected through a fuel injection pipe (400) to a fuel injection nozzle (500), is improved in that the inner diameter of the fuel injection pipe is rededuced from the side of the fuel injection pump towards the side of the full injection nozzle. The inner diameter of the fuel injection pipe could be reduced from the side of the fuel injection pump towards the side of the fuel injection nozzle either in a stepwise manner or continuously.
