特徴とする複吸気弁エンジン。 A first intake passage that is always open and a second intake passage that is provided with an intake control valve that opens and closes depending on the engine load are connected to the engine combustion chamber, respectively, and the first intake passage is connected to the engine combustion chamber. In a dual intake valve engine in which a fuel injection valve is provided in an intake passage, an exhaust gas recirculation passage is opened downstream of the intake control valve in the second intake passage via an exhaust recirculation gas valve, and the exhaust gas recirculation passage is opened downstream of the intake control valve in the second intake passage. A multiple intake valve engine characterized in that the opening timing of the valve is earlier than the fuel injection timing of the fuel injection valve.
