Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection nozzle capable of improving fuel consumption and exhaust.
SOLUTION: In the fuel injection nozzle 1A, a needle valve 20 is stored in a nozzle body 10 provided with an injection hole 12 reciprocatably along a central axis AX and the fuel is injected from the injection hole 12. An opening part of the needle valve 22 for closing an opening so as to be opposed to the opening 12HL on an inner side of the injection hole is formed by a member 30 having lower hardness and wearing-resistance than the material of the needle valve 22 and the material of the nozzle body 10. Even when slight manufacturing error exists, it can conform to the periphery by deforming a filling member 30 itself or chipping or abrading an abutment portion. Thereby, since the opening part becomes a flat surface-like shape not containing an excessive space, the fuel injection nozzle can efficiently control the flow of the fuel and can improve the fuel consumption and the exhaust.

Abstract: PROBLEM TO BE SOLVED: To provide a device for reforming fuel for an internal combustion engine capable of reducing hazardous substance in exhaust gas and providing ideal performance by small quantity of charged energy and by a simple method. SOLUTION: This fuel reforming device has a minute air bubble introducing means 20 for introducing minute air bubbles into a fuel tank 10 and fuel and an oxygen concentration control means 30 for increasing and reducing oxygen concentration of minute air bubble forming gas in accordance with a combustion condition in the internal combustion engine. Minute air bubble has various characteristics allowing expectation of improvement of combustion characteristics by determining from its size. Since minute air bubble introduced into fuel for the internal combustion engine is supplied into an engine cylinder while it remains in the vicinity of fuel for the internal combustion engine, influence that composition of minute air bubble forming gas gives to combustion is large. In particular, great influence is given to local equivalent ratio by controlling oxygen concentration in minute air bubble. Consequently, combustion conditions for the internal combustion engine can be easily made proper by comparatively simple device. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To produce a sintered body having a fine and rigid high electric resistance layer on the surface of soft magnetic powder through a simple process using inexpensive soft magnetic powder principally comprising iron as a material.
SOLUTION: Fe-Si alloy powder is heated in weak oxidizing atmosphere to form an SiO
2 oxide film on the surface and after being pressed, it is calcinated in weak oxidizing atmosphere to produce a sintered body. Surface oxidation process is carried out in weak oxidizing atmosphere of steam, or the like, to oxide Si selectively thus forming a thin oxide film of high electric resistance, which is then further calcinated in weak oxidizing atmosphere. The oxide film cracked at the time of press molding is repaired by repeating oxidation in pressurization atmosphere and degassing in pressure reduction atmosphere thus obtaining a high quality sintered body.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection nozzle 1 for conducting injection-supply of fuel to an engine in which diffusibility of injected fuel is improved.
SOLUTION: A 1st and a 2nd nozzle holes 2, 3 respectively are provided axially in the same line in the axial direction of the fuel injection nozzle 1 so that respective axes are not parallel, and are twisted without intersection. Thus, jets from the 1st and the 2nd nozzle holes 2, 3 interfere with each other without coming into collision. Since the 1st and the 2nd nozzle holes 2, 3 are twisted, injection flows from the nozzle holes 2, 3 are diffused swirlingly. Thus, the injection fuel is diffused in a more widespread space than in the case where the axes of the 1st and the 2nd nozzle holes 2, 3 are set parallel to allow the jets to interfere parallel with each other, and in the case where the axes of the 1st and the 2nd nozzle holes 2, 3 are set so as to intersect so that the jets are allowed to collide and diffused unidirectionally at a wide angle.

Abstract: PROBLEM TO BE SOLVED: To accurately detect abnormality of a fuel flow amount by providing a position detection means detecting a position of a valve member which is displaced in accordance with the fuel flow rate, in a fuel cutoff valve provided in a fuel supply route to interrupt it when fuel of specified rate or more flows. SOLUTION: At the time of normal fuel flow, when it is injected from a fuel injection valve, the fuel flows in a fuel passage 21a, and by generating a differential pressure between the upstream/downstream of an orifice 31a, a piston 31 is moved downward. After completion of injection, the piston 31 is returned back to a position of the origin. In a condition that the fuel passage 21a is thus interrupted, a minimum/maximum lift of the piston 31 is equalized, and in an ECU, when the minimum lift exceeds an upper limit lift threshold value, a fuel cutoff condition is judged. On the other hand, when fuel leakage is generated in a fuel supply route to the fuel injection valve, the minimum lift is prevented from being a lower limit lift threshold value or less, so generation of the fuel leakage is judged.
