摘要： PROBLEM TO BE SOLVED: To provide a torque detector, with which the torque generated in a shaft-shaped magnetic rotation member is detected with good accuracy by a method, where the positional relationship between the exciting coil and the detecting coil of every magnetostrictive sensor is contrived. SOLUTION: In both magnetostrictve sensors 30, 40 the coil face of every detecting coil is set at a prescribed angle +θ with reference to the axis of exciting coil. A microcomputer 54 corrects detection outputs of both the magnetostrictive sensors 30, 40, so as to be placed on the same output torque characteristic. On the basis of both the corrected outputs, the torque of a crankshaft is calculated.

摘要： PURPOSE:To achieve high NOx purification factor, by making use of the temperature transition property of a catalyst for reduction of NOx, and also, maintain the excellent fuel consumption rate of a diesel engine. CONSTITUTION:When a control circuit 6 judges that the temperature of a catalyst is in temperature bounds such as the range from the catalyst activity lower limit temperature to the upper limit set temperature by the signal of the temperature sensor 3 annexed to a zeolite catalyst 2, and that this is in such condition that the catalyst may be supplied with HC by the signals being output by an acceleration aperture sensor or a revolution sensor for detecting the operation state of a diesel engine, it issues HC supply signals intermittently to a supply device 5. The catalyst 2 reduces and purifies the NOx in exhaust by the HC supplied intermittently, and also repeats temperature up and temperature down, but the NOx purification factor of the catalyst improves by the temperature up transition property of the catalyst, and it can reduce and purifies NOx more efficiently than the case of supplying HC stationarily.

摘要： PROBLEM TO BE SOLVED: To provide practical constitution of high detection precision for detecting torque of a rotary body.
SOLUTION: A detecting ring 2 of which the both ends 21, 22 are pressure- contact-fixed to the rotary body 81 is fitted with the rotary body 81 for transmitting the detected torque, and a torsion equivalent to a torsion of the rotary body 81 is accurately produced in non-fixed part 23 contactless with the rotary body 81. A large number of slender grooves are formed along a circumferential direction of the detecting ring 2 in the non-fixed part 23, and the grooves are arranged in an axial direction of the detecting ring 2 to form two kinds of grooves tilted at 45° with respect to the axial direction of the detecting ring 2 and grooves tilted at 40° in an opposite side thereof. A longitudinal-directional groove direction is conformed with a direction of a shearing strain by the torsion of detecting ring 2 in one-side grooves and made orthogonal thereto in the other-side grooves, a boundary part 24 in the two kinds of grooves is displaced axis-directionally in response to a level of the torque, and a torque sensor 3 is used as a sensor for detecting the displacement to widen selection ranges for a material of the detecting ring 2 and a type of the torque sensor 3.

摘要： PROBLEM TO BE SOLVED: To enhance detection precision in a non-contact type torque detector. SOLUTION: A cylindrical magnetostrictive member 2 constituted of a magnetostrictive material is fitted in an outer circumference of a shaft-like rotor 81 for transmitting torque, and a torque sensing part 231 different in torsion in response to the torque and a torque non-sensing part 232 are provided in the cylindrical magnetostrictive member 2. Magneto-striction in the sensing part 231 is detected by a torque sensing part detecting means 31, and magneto- striction in the torque non-sensing part 232 is detected by a torque sensing part detecting means 32. The magneto-striction in the torque sensing part 231 is offset-corrected with the magneto-striction in the torque non-sensing part 232. Offset fluctuation caused by changes of a rotational angle and an ambienet temperature of the rotor 81 is prevented to enhance the detection precision.

摘要： PURPOSE: To increase a HC amount meeting operating condition of an engine in an exhaust emission control system simply. CONSTITUTION: In a feed pump for supplying fuel to a fuel injection pump 1 by pressurizing fuel in a comparatively low pressure, the operating condition of an internal combustion engine, for example, it is noticed that feed pressure of fuel whose volume is changed according to rotating speed is generated. A part of fuel of feed pressure is taken out to a HC feed line 2 by a HC taking- out part 2a, pressure is regulated by a throttle 3, and it is supplied to a HC feed device 5 arranged upstream from an exhaust emission control system (for example, a catalyst). Exhaust purifying action is assisted as amount increasing HC by fuel which is mixed with exhaust gas and supplied to the exhaust emission control system 6. Since the amount of fuel supplied as HC is automatically regulated to a volume meeting operating condition of an engine, HC is supplied without the shortage even if complex means for regulating a HC feed amount especially is not used. A control valve 4 for opening/closing controlling by a simple control circuit 11 and an exhaust temperature sensor 7 are arranged.
