摘要： PROBLEM TO BE SOLVED: To provide a torque detector for accurately detecting torque generating in an axial magnetic rotational member without depending on rotation angle sensor by devising the constitution of a magnetostriction sensor. SOLUTION: A detection core 32 positions inside an excitation core 31 and the detection core is arranged to face to the circumferential surface of a magnetostriction part 22 of a detection ring 20 at both legs 32a and to be perpendicular to the axis direction of the magnetostriction part 22. A correction core 33 is in the same plane as the excitation core 31 and is arranged to be perpendicularly face to circumferential surface of a magnetostriction part 22 of a detection ring 20 at both legs 33a and to be along the axial direction of the magnetostriction part 22. The difference between the detection output of a detection coil 35 wound on the detection core 31 and the correction output of the correction coil 36 wound on a correction core 33 is output as a torque detection signal.

摘要： PROBLEM TO BE SOLVED: To make uniform the linear velocity distribution inside a catalyst structure for accelerating the activation of a catalyst, wherein the catalyst structure consists of a plurality of monolith catalyst pieces arranged in series in the exhaust gas flowing direction. SOLUTION: A catalyst structure 1 includes two catalyst pieces 2 and 3 consisting of honeycomb structure composed of bulkheads 21 and 31 of a constant thickness installed at a certain spacing in matrix arrangement formed from lines and columns and cell holes 22 and 32 partitioned by the bulkheads 21 and 31, and these catalyst pieces 2 and 3 are arranged adjoiningly in series in the exhaust gas flowing direction G inside an exhaust pipe 4, wherein the bulkhead 31 of the downstream catalyst 3 has one smaller number of lines and columns than those of the upstream catalyst 2. The positional relationship between the bulkheads 21 and 31 of the two catalysts 2 and 3 is such that the degree of positioning of the downstream bulkhead 31 within the cell holes 22 in the upstream catalyst 2 is greater in the central part of the cross-section of the exhaust gas flow in the exhaust pipe 4 and becomes smaller as going toward the periphery.

摘要： PROBLEM TO BE SOLVED: To make the detection precision of a noncontact-type detector higher. SOLUTION: On the periphery of a shaftlike rotating body 81 which transmits torque, a cylindrical magnetostrictive member 2 made of magnetostrictive material is fitted. From the quantity of magnetostriction in accordance with the torsion of the magnetostrictive member 2, torque is detected. Besides, generation of a detection error caused by expansion by temperature of an adhesive agent, etc., is prevented by press-fitting and fixing both ends 21, 22 of the cylindrical member 2 to the periphery of the rotating body 81 without using an adhesive agent. By not fixing the other part 23 of the magnetostrictive member 2, uniform torsional deformation free from defective deformation caused by influence of friction with the rotating body 81, etc., and according to the torsion of the rotating body 81, is generated in the nonfixing part 23, and detection precision is made higher.

摘要： PROBLEM TO BE SOLVED: To simplify the structure of a conduit line, and to prevent that the fuel is continued to inject in the disorder condition of a two-way valve for injection control, in a high pressure fluid injection device. SOLUTION: A needle 12 to open and close an injection hole 101 for fuel injection purpose is controlled by increasing and decreasing the pressure of a control hydraulic chamber 106 generating its back pressure. The high pressure fuel leading-in to the control hydraulic chamber 106, and the release of the high pressure, are carried out by a single common use conduit line 21, by switching a two-way valve 42. Inside a tubular body 11 is made into a valve chest 103 and a cylinder 105, and a needle 12 is held slidable in the cylinder 105 to prevent the leakage of the fuel from the sliding part of the needle 12 to the other part, so as to make a drain conduit line unnecessary. The leading-in of the high pressure fuel to the valve chest 103 is carried out through a check valve 14, and the fuel leading-in to the valve chest 103 is prohibited as well as the inside of the valve chest 103 is maintained at a high pressure, so as to prevent the continuous injection of the fuel.

摘要： PROBLEM TO BE SOLVED: To reduce adhesion of particulate to the interior of an intake pipe and to eliminate a need to perform after-processing of particulate accumulated at a filter by a method wherein the end part on the exhaust pipe side of an exhaust gas conduit, communicated with an intake system, is protruded in an exhaust pipe and the terminal opening thereof is pointed to the direction of a flow of exhaust gas. SOLUTION: A part of exhaust gas discharged in an exhaust pipe 3 from an engine 1 flows through the terminal opening 42 of an EGR conduit 4 to an intake pipe and is mixed with intake air. The maximum combustion temperature of the engine 1 is decreased by the mixture and oxidation reaction of nitrogen is suppressed. In this case, the end part 41 of the EGR pipe 4 is extended through an exhaust pipe 3 wall and protruded in the exhaust pipe 3, and bent in an L-shape to the opposite side to the engine 1 at the central part of the cross section of the exhaust pipe 3, and a terminal opening 42 is pointed to a spot situated downstream of an exhaust gas flow. This constitution reduces an amount of particulate adhered and accumulated on the intake pipe and eliminates a need to mount a member for capturing the particulate in the EGR conduit 4.
