Claims

[Claims for Utility Model Registration] 1. A main intake passage provided with a main intake control valve, a normally open first intake passage branching from the downstream side of the main intake control valve of the main intake passage, and a first intake passage provided with an engine load. a second intake passage provided with an auxiliary intake control valve that opens and closes in response to the auxiliary intake control valve; a fuel injection valve is provided downstream of the auxiliary intake control valve in the second intake passage; In a dual-intake valve engine in which an intake passage is connected to an engine combustion chamber through each intake valve, a bypass passage is provided that branches from an upstream side of the main intake control valve of the main intake passage and reaches the fuel injection valve, The bypass passage is provided with an on-off valve that controls opening and closing of the passage, and the on-off valve is opened from the start of fuel injection during the intake stroke until a predetermined time after the fuel injection stops. Dual intake valve engine. 2. The dual intake valve engine according to claim 1, wherein the opening/closing control valve is a solenoid valve controlled by a computer.
