In a combustion unit, a fuel collision member is disposed between a fuel injection valve and a combustion chamber. The fuel collision member is positioned so that, a part of fuel injected from said fuel injection valve is introduced into the combustion chamber while colliding with the fuel collision member, and the other part of fuel is directly introduced into the combustion chamber without colliding with the fuel collision member. Thus, fuel introduced into the combustion chamber is atomized while being introduced into the combustion chamber in a wide range.

1. A combustion device comprising:a combustion receiver for defining a combustion chamber; a fuel injection unit having an injection port for injecting fuel to be introduced into said combustion chamber; an air supplying unit for supplying air into said combustion chamber; an ignition unit for igniting a mixed gas between fuel and air in said combustion chamber; and a fuel collision unit disposed between said injection port and said combustion chamber in such a manner that, a first part of fuel injected from said injection port of said fuel injection unit directly collides with said fuel collision unit, and a second part of fuel is directly introduced from said injection port to said combustion chamber; wherein: said fuel collision unit includes a plate portion having a first surface on a fuel injection side of said fuel injection unit and a second surface on a side of said combustion chamber; said plate portion has an inner wall defining a fuel opening through which fuel injected from said fuel injection unit passes; and said fuel injection unit and said fuel collision unit are disposed in such a manner that, when fuel injected from said injection port of said fuel injection unit passes through said fuel opening, a part of fuel is introduced into said combustion chamber while colliding with the inner wall and the other part of fuel is introduced into said combustion chamber through said fuel opening while being prevented from colliding with said inner wall.
