Claims

[Scope of utility model registration request]

It is equipped with three intake valves consisting of a first intake valve, a second intake valve and a third intake valve, and three intake passages consisting of a first intake passage, a second intake passage and a third intake passage. A first intake passage for generating a swirling flow inside the room is connected to the combustion chamber through the first intake valve, and a second intake passage connected to the combustion chamber through the second intake valve is connected to the combustion chamber through the second intake valve. An intake control valve that opens when In a fuel injection type internal combustion engine in which the third intake valve is opened from near the center of the intake stroke to the beginning of the compression stroke, the inlet portions of the first intake passage, the second intake passage, and the third intake passage are connected to a common a first nozzle hole opening into the intake passage and a fuel injection valve disposed within the common intake passage, the fuel injection valve being oriented toward the inlet of the first intake passage; and an inlet of the second intake passage; a second nozzle hole oriented toward the
A fuel injection type internal combustion engine includes a plurality of intake valves each having a third nozzle hole oriented toward the entrance of an intake passage and having the largest injection amount.
