ABSTRACT:
An auxiliary fuel injection unit includes two surge tanks partitioned by a wall surface, a butterfly valve for switching between connection and disconnection of two surge tanks, and one auxiliary fuel injection valve for injecting an auxiliary fuel in a direction opposing a direction of flow of intake air within the surge tank. The butterfly valve has a valve plate surface closing an opening provided in the surge tank wall surface and a rotation shaft for turning the plate surface. The auxiliary fuel injection valve has two injection holes connecting with each other, for injecting the auxiliary fuel toward the valve plate surface of the butterfly valve and toward the surge tank wall surface.
