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： 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.

摘要： The invention provides an apparatus and method for diagnosing breached fuel elements in a nuclear reactor. A detection system measures the activity of isotopes from the cover-gas in the reactor. A data acquisition and processing system monitors the detection system and corrects for the effects of the cover-gas clean up system on the measured activity and further calculates the derivative cure of the corrected activity as a function of time. A plotting system graphs the derivative curve, which represents the instantaneous release rate of fission gas from a breached fuel element.
