摘要： PROBLEM TO BE SOLVED: To provide a burner apparatus excellent in flame insulation capability and performing stable combustion even when the amount of injection of fuel gas is reduced. SOLUTION: There are provided first nozzle means 10 for specifying a first flow passage 45, second nozzle means 12 for specifying a second flow passage 47, an injection nozzle body 20 having an injection hole 48 for injecting fuel gas, and an air flow passage 8 for supplying air to the first and second flow passages 45, 47. When the amount of supply of fuel gas is little, an injection speed thereof is reduced, and the fuel gas flows into the first flow passage 5 by receiving action of the air stream flowing through the first flow passage 45, while, when the amount of supply of the fuel gas is much, an injection speed thereof is increased, whereby the fuel gas surmounts the air stream flowing through the first flow passage 45 and flows through the second flow passage 47.

摘要： PROBLEM TO BE SOLVED: To properly adjust self-ignition timing with a simple structure, in a pre-mix compression self-ignition engine maintaining rotation of a crankshaft, having an intake stroke allowing an intake of a fuel and an oxygen-containing gas for combustion into a cylinder from at least one intake passage, a compression/expansion stroke allowing compression and self-ignition of a premixture within the cylinder, and an exhaust stroke allowing exhaust of exhaust gas within the cylinder after the compression/expansion stroke from at least one exhaust passage. SOLUTION: In this engine, the timing of compression self-ignition in an engine operation cycle can be detected, and a portion of exhaust gas can be supplied into a cylinder 3 before the compression self-ignition by opening/closing timing control of an air supply valve 1 or an exhaust valve 2. The amount of the exhaust gas supplied into the cylinder 3 before the compression self- ignition is controlled according to the timing of the detected compression self- ignition to control the timing of the compression self-ignition.

摘要： PURPOSE:To eliminate the unevenness of the applied surface of a catalyst and the nonuniformity of the applied amount among products and to make the detecting characteristics for every product uniform by containing a second substrate having a gas sensitive body on the surface into the recess part of a first substrate, and applying the catalyst on the position covering the recess part. CONSTITUTION:A glass substrate 10 on which a gas sensitive body 11 is provided is contained in a recess part 4a of a heater substrate 4. Under this state, a catalyst layer 13 is applied so as to cover the recess part 4a. The catalyst layer 13 is formed by screen printing so as to cover both the substrate 10 and the substrate 4 under the state wherein a part of each of electrodes 12 and 12 is exposed. The substrate 10 is bonded to the substrate 4 by the application of the catalyst layer 13. In this constitution, the surface of the substrate 4 and the surface of the substrate 10 form the approximately same plane. Therefore, the catalyst layer 13 can be uniformly applied. The amount of the application becomes uniform regardless of products. The 'dispersion' in detecting characteristics for every product can be eliminated.

摘要： PURPOSE:To decrease the fluctuation in the temp. of a gas sensitive body and to prevent the degradation in characteristics and yield by providing conductive leads with heat radiating parts for controlling the temp. of the gas sensitive body which are arbitrarily cut and removed according to the temp. states of the gas sensitive body. CONSTITUTION:The leads 9a, 9b for electrodes and the leads 10a, 10b for heaters consist of blank materials, such as nickel and extend nearly perpendicularly from the two sides 11a, 11b of a leaf frame 11 toward the central side. The respective leads 9a, 9b, 10a, 10b are integrally provided with the heat radiating parts 12a to 12d for controlling the temp. of the gas sensitive body. The heat radiating parts 12a to 12d are made of rectangular plates and are coupled via the fine width parts 13a to 13d thereof to the respective leads 9a, 9b, 10a, 10b in such a manner that heat can be transferred. The heat radiating parts 12a to 12d are so set that the volume (surface area) thereof is 1/4 the volume (surface area) of the leads 9a, 9b, 10a, 10b. If, therefore, the heat radiation quantity form, for example, a piece of the lead is assumed to correspond to the quantity to lower the temp. of the gas sensitive part 1 by about 20 deg.C, the temp. of the gas sensitive part 1 can be increased by about 5 deg.C by cutting the one heat radiating part.

摘要： PURPOSE:To always carry out the proper air-fuel ratio control by reducing the set value for feedback of an O2 sensor by a prescribed value when the detection value of a CO sensor exceeds a set value when the load and revolution speed of an engine are constant for a prescribed time. CONSTITUTION:A control valve 7 installed in an air bypass line 6 is opening/ closing-controlled by a controller 8 according to the magnitude of the detection value of an O2 sensor 1 installed before a catalytic layer 4 in the exhaust line 3 of an engine 1, and air-fuel ratio is adjusted. In this case, an exhaust bypass line 9 is installed onto the outlet side of the catalytic layer 4 in the exhaust gas line 3. Further, a CO sensor 10 is arranged in the exhaust bypass line 9, and a valve 11 and a suction pump 12 are arranged on the starting edge side. The detection value of the CO sensor 10 is inputted into the controller 8, and when the detection value of the CO sensor 10 exceeds a set value, the set value of the O2 sensor 1 is reduced by a prescribed value.

摘要： PURPOSE:To suppress the decrease of the resistance of a sensor with lapse of time and to prevent the breakdown thereof by impregnating a silicic acid soln. having a prescribed degree of polymn. to a molding formed by embedding electrodes therein and precalcining the molding, then subjecting the molding to normal calcination under specific conditions. CONSTITUTION:The molding 6 of SnO2 embedded therein with electrode 2 in common use as a heater and the detecting electrode 4 is precalcined and thereafter, the soln. of silica having 2-3 average degree of polymn. is dropped onto the molding 6 to impregnate the silica therein. The electrodes 2, 4 are energized after air drying, by which the molding is subjected to the normal calcination for 10-60min at 700-800 deg.C. The silica added to the molding 6 is penetrated into the molding by the normal calcination and is deposited on the surface of the molding 6 to form a silica film 8. The resistance change of the sensor with lapse, of time is decreased and the breakdown thereof is hardly generated according to the above-mentioned method.
