Claims

[Claims for Utility Model Registration] 1. A first intake port that is always open to generate a swirl in the intake air supplied into the combustion chamber, and an intake control valve that is opened only in the high-load, high-speed operating range of the engine; It is equipped with a second intake port that supplies straight intake air into the room, and a third intake port that is provided with a fuel injection valve.
and a third intake port respectively to the first, second and third intake ports.
In a dual intake valve engine, the first and third intake valves are connected to a combustion chamber through intake valves thereof, and the opening timing of the third intake valve is delayed from the opening timing of the first intake valve. The port is arranged as a Siamese-type port whose upstream side communicates with a common intake passage, and the fuel injection valve is arranged in the common intake passage to supply fuel to both the first and third intake ports. A dual intake valve engine characterized by being configured to. 2. The fuel injection valve is a two-way injection valve in which fuel is injected in two directions: a first intake port direction and a third intake port direction.Claim 1 of the Utility Model Registration Claim. Dual intake valve engine as described. 3. The first intake port is provided with a deflection plate on the upstream side of the fuel injection valve to generate a biased flow in the first intake port. intake valve engine.
