のデイーゼルエンジンの燃料噴射装置。[Claims for Utility Model Registration] 1. A fuel injection device for a diesel engine, which has a nozzle hole exposed to a combustion chamber, and in which a needle valve element for opening and closing the nozzle hole can be moved forward and backward into an internal space communicating with the nozzle hole. a nozzle having a single return chamber arranged therein; a first fuel supply system including a pump that is connected to the return chamber and pressure-feeds main fuel such as light oil to the return chamber; and a second fuel supply system including a pump that is connected to the return chamber and pumps a different type of fuel such as alcohol to the return chamber, and at the start of fuel injection, returns the main fuel from the first fuel supply system to the return chamber. 1. A fuel injection device for a diesel engine, characterized in that the fuel injection device for a diesel engine is configured to pressure-feed a different type of fuel to a fuel chamber, and then control the supply of a different type of fuel from a second fuel supply system depending on the load of the engine. 2. A fuel injection device for a diesel engine according to claim 1, wherein the amount of main fuel supplied is substantially constant regardless of the engine load.
