Abstract: PROBLEM TO BE SOLVED: To further promote spraying-atomization by further thinning a fuel flow in a nozzle as a thin film, in an injector.SOLUTION: A guide surface 41 is arranged in a tip part of a needle valve 3 so as to extend to the inner peripheral side by continuing with a seating surface 22 by becoming a steeper slope than the seating surface 22 by an angle θ1, and a nozzle inner peripheral sidewall surface 42 is inclined toward the outer peripheral side relative to the guide surface 41 by an angle θ2. Thus, the seating surface 22 leaves from a seating object surface 21, and when fuel flows toward the nozzle 14 from a fuel flow passage 12, the fuel passed through between the seating surface 22 and the seated object surface 21 is intensively pressed to the guide surface 41 and flows in the nozzle 14. The fuel flowed in the nozzle 14 is further intensively pressed to the nozzle inner peripheral sidewall surface 42. Thus, the fuel flow in the nozzle 14 is further thinned as the thin film, and the spraying-atomization can be further promoted.

Abstract: PROBLEM TO BE SOLVED: To further promote spray atomization by further thinning the film of a fuel flow in a nozzle port 14, in an injector. SOLUTION: The end of a needle valve 3 is formed with a guide surface 41 steepened by an angle θ1 in comparison with a seating surface 22, continued to the seating surface 22 and extending to the side of an inner periphery. A wall surface 42 on the side of the inner periphery of the nozzle port is inclined by an angle θ2 toward the side of an outer peripheral with respect to the guide surface 41. When the seating surface 22 is separated from a seated surface 21 and fuel flows from a fuel flow passage 12 toward the nozzle port 14, fuel passed between the seating surface 22 and the seated surface 21 is pushed to the guide surface 41, collected, and led to flow into the nozzle port 14. Fuel led to flow into the nozzle port 14 is pushed to the wall surface 42 on the side of the inner periphery of the nozzle port, and further collected. Therefore, the spray atomization is further promoted by further thinning the film of the fuel flow in the nozzle port 14. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a control system of an in-vehicle apparatus capable of suggesting a service provided by a further suitable in-vehicle apparatus in a situation where a vehicle is placed.
SOLUTION: The situation where the vehicle is placed is detected to estimate an in-vehicle apparatus to be controlled. The voice and action of an occupant are detected to decide an in-vehicle apparatus to be controlled and control contents thereof. By detecting the voice and action of the occupant of the vehicle, information which cannot be obtained by a sensor and the like mounted on the vehicle, and the occurrence of a situation requiring the control even if conditions for executing the control are not completely satisfied, can be detected from the voice and action of the occupant. By deciding the in-vehicle apparatus to be controlled and control contents thereof on the basis of the voice and action of the occupant, it becomes possible to suggest a service by the further suitable in-vehicle apparatus to the occupant of the vehicle, in the situation where the vehicle is placed.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection valve reducing energy of an electromagnetic drive part 6. SOLUTION: A diaphragm 7 collapsed by rise of a fuel pressure for reducing set load of a spring 5 is disposed on a supporting point on an upper side of the spring 5. During cranking until initial explosion, the fuel pressure is low and the diaphragm 7 is in an expanded state. As load in the valve closing direction applied to a needle 4 is high, the needle 4 is not lifted by effect of the initial explosion. After an engine is started, the diaphragm 7 is completely collapsed by rise of the fuel pressure and the load in the valve closing direction applied to the needle 4 is reduced. However, the needle 4 is not lifted by an effect of combustion. During normal operation after start of the engine, since the load in the valve closing direction is reduced, energy of the electromagnetic drive part 6 is reduced. With the same amount of energy consumption as before, even when the fuel pressure is increased, the fuel injection valve is stably operated to open and close. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection valve 1 which prevents its needle 7 from making a poor operating performance even in case an inclination occurs in the elongating/contracting direction of a piezoelectric actuator 3.
SOLUTION: A pressurizing piston 4 is composed of: a head part 4a abutting to the axial direction end face of the piezoelectric actuator 3 and receiving the displacement of the piezoelectric actuator 3; and a piston wall 4b in cylindrical shape receiving the motion of the head part 4a and moving in the axial direction, wherein these two parts are combined to be relatively movable in the radial direction. The movement of the head part 4a in the radial direction is restricted by an outer sleeve 5 to hold the periphery of the piston wall 4b slidably. According to the constitution described above, a deflection in the radial direction is generated between the head part 4a and the piston wall 4b in case the elongating/contracting direction of the piezoelectric actuator 3 is inclined relative to the axial direction, which suppresses inclination of the piston wall 4b, so that the piston wall 4b is prevented from seizing the outer sleeve 5.

Abstract: PROBLEM TO BE SOLVED: To provide an ignition timing control method and device for a premixed compression ignition engine of simple structure.
SOLUTION: The ignition timing control device for controlling the ignition timing of the premixed compression ignition engine 10 has a laser generators 1, 1' for generating predetermined laser beams 2, 2'; a condensing irradiation means 3 for condensing and irradiating predetermined laser beams generated from the laser generators 1, 1', toward a combustion chamber 7 of the premixed compression ignition engine 10. The condensing irradiation means 3 condenses and irradiates the predetermined laser beams 2, 2' toward the combustion chamber 7 to produce an oxygen radical (O*). Since only the condensing irradiation of predetermined laser beams toward the combustion chamber is carried out, the conventional premixed compression ignition engine has only to be provided with a laser light source for generating laser beams, and a condensing irradiation means for condensing and irradiating the laser beams. Structure can thereby be made extremely simple.
