    摘要： A fuel supplying apparatus of an internal combustion engine includes a first fuel supply system, a second fuel supply system, and a pulsation propagation suppressing unit. The first fuel supply system pressurizes a fuel by a low-pressure pump, and supplies the fuel pressurized by the low-pressure pump to a first fuel injection mechanism. The second fuel supply system is branched from the first fuel supply system, further pressurizes the fuel, pressurized by the low-pressure pump, by a high-pressure pump that is driven according to an operating state of the internal combustion engine, and supplies the fuel pressurized by the high-pressure pump to a second fuel injection mechanism. The pulsation propagation suppressing unit is provided in at least one of the first fuel supply system and the second fuel supply system, and suppresses propagation of a pulsation generated in the high-pressure pump to the first fuel injection mechanism.

    摘要： A fuel injection device for an engine includes a direct injector and an intake passage injector. When the engine load is relatively low, a fuel pressure lowering procedure is executed for lowering the pressure of fuel supplied to the direct injector. An ECU sets a fuel injection ratio, which is the ratio between the fuel injection amount of the direct injector and that of the intake passage injector, based on the engine operation state. The ECU changes the fuel injection ratio such that the ratio of the fuel injection amount of the direct injector to the total amount of the fuel fed to a combustion chamber is decreased, until the pressure of the fuel supplied to the direct injector is raised from the value lowered through the fuel pressure lowering procedure to a predetermined permissible value. This effectively suppresses hampering of the engine combustion, caused by the lowered fuel pressure.

    摘要： When an inner wall of a cylinder head is viewed along an axis of a cylinder, a line that passes through a center of a fuel injection port and a center of a valve opening adjacent to the injection port is defined as a first line, and a line that is perpendicular to the first line is defined as a second line. A notch is formed in a part of the inner wall that defines the injection port. Specifically, when the inner wall is divided into sections by the second line, the notch is located in the section in which the adjacent opening exists. The notch is also displaced from the first line. Therefore, a sufficient thickness of the section corresponding to the valve seats of intake and exhaust valves are easily ensured.
