    摘要: A control device (5) for an internal combustion engine including a fuel injection device (3) is provided. The fuel injection device (3) includes an injection hole (31b, 31c), and is configured to inject fuel from the injection hole (31b, 31c) into a combustion chamber (21). The control device (5) includes an actual injection amount output section (53), an injection amount deviation output section (51a), and an abnormality treatment direction section (51a). The injection amount deviation output section (51a) outputs a signal that indicates the deviation between an actual injection amount and a command fuel injection amount. The abnormality treatment direction section (51a) outputs a signal to enable treatment if the deviation exceeds a predetermined value.

    摘要: A fuel injection device (1) includes a fuel injection valve (2) that injects fuel, and is provided with a first nozzle hole (9) and the second nozzle hole (10), which are controlled independently of each other to inject the fuel. The fuel injection device further includes a controller (5) that performs a deposit removal fuel injection in accordance with an amount of deposits accumulated in the first nozzle hole and/or the second nozzle hole. The deposit removal fuel injection injects fuel to remove the deposits.

    摘要: An outer needle valve (42) and an inner needle valve (43) face on back sides thereof an outer control chamber (R2) and an inner control chamber (R3), which are independent of each other, respectively. An outer fuel outflow passage (C4) and an inner fuel outflow passage (C5) for causing fuel to flow out from the outer control chamber (R2) and the inner control chamber (R3) respectively meet at a meeting portion (Y). A control valve (45) for rendering in communication/shutting off a fuel discharge passage (C6) for connecting the meeting portion (Y) to a fuel tank (T) is interposed in the fuel discharge passage (C6). An automatic valve (44) as an open/close valve for shutting off the outer fuel outflow passage (C4) when a rail pressure (Pcr) is equal to or lower than a predetermined value and rendering in communication the outer fuel outflow passage (C4) when the rail pressure (Pcr) is higher than the predetermined value is interposed in the outer fuel outflow passage (C4).

    摘要: When a control valve 48 allows communication through a fuel drain channel C3, fuel flows into an inner control chamber R2i from an outer control chamber R2o through a communication channel 47 and flows out from the inner control chamber R2i to a fuel tank T. The flow of fuel through the communication channel 47 generates a differential pressure between inner control pressure Pci and outer control pressure Pco (Pco>Pci). Thus, an outer differential pressure immediately after an outer valve opening time can be set small, thereby restraining an increase in the unburnt HC content of exhaust gas at low load, which could otherwise result from a high rising speed of an outer needle valve 42 immediately after the outer valve opening time. Also, an inner differential pressure immediately after an inner valve opening time can be set large, thereby restraining an increase in the smoke content of exhaust gas, which could otherwise result from a low rising speed of an inner needle valve 43 immediately after the inner valve opening time.
