Filed: 2000-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection device capable of controlling a fuel injection rate according to an engine operating state so as to simultaneously reduce NOx, HC, and black smoke and improve fuel consumption output. SOLUTION: A needle 21 receives force from the fuel pressure of a first control chamber 25 in a nozzle hole closing direction, and receives force from the fuel pressure of a fuel collecting portion 56 in a nozzle hole opening direction. When voltage is applied to a piezoelectric element 30, the fuel pressure of the first control chamber 25 and a second control chamber 26 is reduced, so that the needle 21 leaves a valve seat 12a to lift by a lift amount H1, and fuel is injected from a nozzle hole 12b. When the voltage applied to the piezoelectric element 30 is dropped, the fuel pressure of the second control chamber 26 rises to raise a second piston 23, so that the needle 21 is lifted again to abut against a tip packing 13 and stopped.  When interrupting the application of the voltage on the piezoelectric element 30, the fuel pressure of the first control chamber 25 is raised, and the force in the nozzle hole closing direction becomes large, so that the needle 21 is seated on the valve seat 12a to finish fuel injection.

Filed: 2000-02-16
Abstract: PROBLEM TO BE SOLVED: To solve the problems with the conventional eccentric centroid disk that, when a disk 1 for evaluation provided with an eccentric centroid member 21 is rotated at a high speed by a disk drive assembly, the level difference (ruggedness) in the part stuck with the eccentric centroid member 21 heretofore induces a local pressure increase by the flow of the air on the disk surface, causing the deformation of the disk 1 and that the follow-up of the servo system of the disk drive assembly to the disk 1 is made difficult by such deformation of the disk 1 and the deviation of servo is resulted in reproduction. SOLUTION: The constitution to eliminate the level difference of the eccentric centroid member 21 or the constitution to provide the eccentric centroid member 21 at a radius 48 mm or below of the disk 1 is adopted. As a result, the flow of the air on the disk surface during high-speed rotation is stabilized and the local deformation of the disk 1 is lessened. The performance evaluation by the disk eccentric centroid of the disk drive assembly is made possible by using the evaluation disk having such eccentric centroid.
