  • Fuel injection apparatus for internal combustion engine
    Patent number: 9429091
    Abstract: A fuel injection apparatus for an internal combustion engine having a plurality of cylinders is provided. The fuel injection apparatus includes a fuel injection valve and an in-cylinder pressure sensor disposed for each of the plurality of cylinders. The fuel injection valve injects fuel into a combustion chamber of each cylinder and the in-cylinder pressure sensor detects a pressure in the combustion chamber. The fuel injection apparatus includes a cylinder pair actuating circuit and a noise suppressing circuit. The cylinder pair actuating circuit is provided corresponding to a cylinder pair which is a combination of two cylinders included in the plurality of cylinders, for supplying actuating current to two actuating solenoids of the two fuel injection valves mounted on the cylinder pair. The noise suppressing circuit is provided between the cylinder pair actuating circuit and the actuating solenoids.
