    摘要: A NOx selective reduction catalyst for reducing NOx by the ammonia adsorbed is disposed in an engine exhaust gas passage. As states of adsorption of ammonia by the catalyst, there are a first adsorption state of ammonia that occurs when the ammonia is adsorbed during low temperature and a second adsorption state of ammonia that occurs when the ammonia is adsorbed or has already been adsorbed during high temperature. The amount of adsorbed ammonia in the first state is restricted to control concentration of the ammonia that is in the first state and desorbed when the temperature of the catalyst increases so as to be not higher than an allowable concentration, and that in the second state is restricted to control concentration of the ammonia that is in the second state and desorbed when the temperature of the catalyst increases so as to be not higher than an allowable concentration.

    摘要: A combustion chamber side end portion of a fuel injection valve is placed at a location that overlaps with an imaginary plane, which is perpendicular to a center axis of a cylinder and extends along a portion of a wall surface of an intake port where an intake valve protrudes, or is projected out from the imaginary plane toward a combustion chamber. Alternatively, a center of a fuel injecting side end port of the fuel injection valve, which injects fuel into intake air that flows in a branch port branched from the intake port, may be placed on the center axis side of the intake valve in a radial direction of the cylinder. Further alternatively, an upstream side fuel injection valve may inject fuel into intake air that flows in the intake port, and a downstream side fuel injection valve may inject fuel into intake air that flows in the branch port branched from the intake port. Alternatively, an injection quantity of fuel may be controlled for each of fuel injection valves, which injects fuel into intake air that flows in the corresponding branch port branched from the intake port.

    摘要: A fuel supply system supplies composite fuel containing alcohol and gasoline to multiple cylinders of an internal combustion engine. The composite fuel includes main-fuel and sub-fuel. The sub-fuel is lower than main-fuel in concentration of alcohol. Each of multiple first fuel injection valves is provided to each of the cylinders for injecting fuel. Each of multiple second fuel injection valves is provided to each of the cylinders for injecting fuel. A fuel inlet portion supplies at least sub-fuel to each of the first fuel injection valves and each of the second fuel injection valves. A selector control unit selects one of main-fuel and sub-fuel supplied through the fuel inlet portion to each of the first fuel injection valves.
