Claims

[Scope of utility model registration request]

At least two consisting of a main intake valve and a sub-intake valve
and at least two intake passages consisting of a main intake passage and a sub-intake passage, and the main intake passage is connected to the combustion chamber via the main intake valve to generate a swirl flow within the combustion chamber. The fuel injection valve is arranged in the auxiliary intake passage connected to the combustion chamber via the auxiliary intake valve, and the main intake valve opens from near the top dead center of the intake stroke to the beginning of the compression stroke, and the auxiliary intake valve opens. A fuel injection internal combustion engine that opens from near the center of the intake stroke to the beginning of the compression stroke is equipped with a common camshaft for driving the main intake valve and the auxiliary intake valve. A fuel injection type internal combustion engine equipped with a plurality of intake valves in which the valve lift of a sub-intake valve is increased by driving the intake valves by a camshaft via a Rocker arm.
