摘要： A fuel injection valve (2) includes a first injection hole group (14), a second injection hole group (15), a control chamber (20), a first needle valve (12), and a second needle valve (13). The first needle valve (12) opens/closes an injection hole in the first injection hole group (14). The second needle valve (13) opens/closes an injection hole in the second injection hole group (15). Lifting of the first needle valve (12), and lifting of the second needle valve (13) are controlled by a pressure of fuel in the control chamber (20). An automatic valve (32) is further provided to change a flow rate at which the fuel flows into the control chamber (20), or a flow rate at which the fuel flows out from the control chamber (20), based on a common-rail pressure in a fuel supply source (1), when the needle valves (12, 13) are lifted. Thus, the fuel injection valve (2) injects fuel at the optimum fuel injection rate in various engine operating states.

摘要： A fuel injection valve (10) with a pressure boosting unit is provided in an engine (1), and boosted pressure fuel injection is performed by increasing a pressure of fuel supplied to a fuel injection valve from a common rail (3). An ECU (20) decides a pressure boosting period that is defined as a time period from when the pressure of the fuel starts to be boosted until when the fuel injection is started using a numerical table in which a fuel injection amount and an engine rotational speed are used as parameters, and sets fuel injection control parameters such as a fuel injection period and pressure boosting starting timing, based on the pressure boosting period. Since the fuel injection control parameters are set based on the pressure boosting period, the control that is performed when the boosted pressure fuel injection is performed is simplified.
