摘要： An excess voltage applied to a piezoelectric element is detected and controlled to improve durability and reliability of the piezoelectric element. A fuel injection control device for an internal combustion engine in which a power source voltage is boosted by a dc-dc converter and the so-boosted output voltage is supplied via a first choke coil and a first thyristor to a piezoelectric element for charging the piezoelectric element, the electric charge of which is subsequently discharged via a second thyristor and a second choke coil. The fuel injection control device includes a positive voltage detection unit for detecting an excess voltage arranged between the first choke coil and the first thyristor and a positive voltage control unit controlled by an output signal of the positive voltage detection unit and adapted for shorting both ends of the first choke coil. The current through the first thyristor is cutoff to prevent the excess voltage from being applied to the piezoelectric element.

摘要： A fuel injection valve includes a fuel swirl generation device, a main fuel injection hole having a comparatively large diameter, and a subsidiary fuel injection hole having a comparatively small diameter. The inclination of the main fuel injection hole with respect to an axis of the fuel injection valve is small so that a fuel swirl remains in the fuel injected therethrough. The inclination of the subsidiary fuel injection hole is great so that the swirl operates so as to push out the fuel through the subsidiary fuel injection hole. The fuel injected through the main fuel injection hole spreads due to the centrifugal force acting on the swirling fuel without depending on an intake gas swirl. The fuel injected through the subsidiary fuel injection hole has a strong penetrating force and can reach the vicinity of a spark plug. This improves ignition without depending on an intake gas swirl. Thus, good combustion is obtained over an entire operation range of a direct fuel injection type engine.
摘要翻译：燃料喷射阀包括燃料涡流发生装置，具有较大直径的主燃料喷射孔和具有较小直径的辅助燃料喷射孔。主燃料喷射孔相对于燃料喷射阀的轴线的倾斜度小，使得燃料喷射通过其中喷射的燃料保留。辅助燃料喷射孔的倾斜度很大，使得涡流操作以便通过辅助燃料喷射孔推出燃料。通过主燃料喷射孔喷射的燃料由于作用在旋流燃料上的离心力而不依赖于进气旋流而扩散。通过辅助燃料喷射孔喷射的燃料具有很强的穿透力并且可以到达火花塞附近。这样可以不依赖于进气旋流来改善点火。因此，在直接燃料喷射式发动机的整个操作范围内获得良好的燃烧。

摘要： A piezoelectric actuator having an active module formed by laminating a plurality of piezoelectric elements, in which the cross-sectional area of the element proximate the fixed end of the module is larger than that of the element proximate the movable end thereof. When the active module expands or contracts, the elements proximate the fixed end receive an inertial load of the elements proximate the movable end. Due to the above structure, a decrease in the inertial load can be realized, thereby preventing the elements near the fixed end from being damaged.

摘要： A torque variation in an internal combustion engine due to the combustion variations is detected at each predetermined period. An average torque variation to be compared with the detected torque variation is predetermined experimentally based on the engine speed and the intake manifold pressure and is stored in a memory. The number of the detected torque variations which exceed the average torque variation multiplied by a predetermined constant is counted, and if the ratio of the counted number to the total number of the detected torque variations is larger than a predetermined reference value, then the presence of a torque variation is determined.
