摘要： In an internal combustion engine, a variable compression ratio mechanism able to change a mechanical compression ratio and a variable valve timing mechanism able to control the closing timing of an intake valve are provided. The mechanical compression ratio is held at a maximum mechanical compression ratio at the engine low load operation side and gradually made to decrease as the engine load increases at the engine high load operation side. The actual compression ratio is held nearly constant at the engine high load operation side and is made to decrease as the engine load decreases at the engine low load operation side.

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： 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.
