The present invention relates to a multi fuel injection device for a diesel engine, which multiply configures a plunger provided in a fuel pump to inject fuel in different injection patterns so as to obtain maximally complete combustion. The multi fuel injection device for a diesel engine according to the present invention is configured with a fuel injection pump for injecting fuel into the combustion chambers of each cylinder via an injector. The fuel injection pump comprises: a housing; a main plunger rising and descending within the housing to inject a main fuel admitted through a main fuel inlet through a main fuel outlet; and a sub-plunger provided in the housing to rise and descend according to the rising and descending of the main plunger, and operate simultaneously with the main plunger to form different injection patterns by admitting sub-fuel through a sub-fuel inlet and injecting the sub-fuel through a sub-fuel outlet, in order to improve a diesel engine's performance. |
