摘要： To enable bonding flat and corrugated sheets at their contact points by laser welding or other welding methods while laminating and spirally winding the sheets, a process of producing a metal catalyst carrier for exhaust gas purification in the form of a metal honeycomb column composed of flat and corrugated metal sheets alternately laminated, wound together, and bonded to each other, the process includes the steps of: forming plural openings in a flat sheet of a metal; laminating one piece of the flat sheet having the openings formed therein and one piece of a corrugated sheet of a metal and bonding the laminated flat and corrugated sheets to each other to form a composite sheet; and spirally winding the composite sheet around an axis to form columnar turns each composed of an outer flat layer composed of the flat sheet and an inner corrugated layer composed of the corrugated sheet, while bonding an outer turn and an adjoining inner turn by welding an inner corrugated layer of the outer turn, in a portion exposed in one of the openings of an outer flat layer of the outer turn, to an outer flat layer of the adjoining inner turn through said one of the openings to bond the outer turn and the adjoining inner turn.

摘要： An exhaust gas purifying apparatus includes a carrier of a honeycomb structure which is made of at least one flat metal plate and at least one corrugated metal plate which is superimposed on the flat metal plate. A catalytic layer is formed on the surface of the carrier. The carrier suited for being coated with the catalytic layer is disposed in an exhaust pipe of an internal combustion engine. The carrier is provided, on an axially intermediate portion thereof, with a large number of louvers which causes a haphazard secondary motion in the exhaust gas. A predetermined portion of the carrier including the turbulence producing portion and an additional region located adjacent to said predetermined region is coated with a larger amount of catalyst than that with which the remaining portion of the carrier is coated, whereby good purifying efficiency can be obtained for a long time.

摘要： A flat-corrugated combined sheet 16 is obtained from a flat sheet 10 and corrugated sheets 12 and 14 which are welded together. The combined sheet 16 is rolled, so that a catalyst carrier 18 of a honeycomb structure to which an exhaust gas is contacted is obtained. At a middle part of the catalyst carrier 18, the flat sheet 10 has a section 10-1 free of corrugated sheet, and is formed with louvers 21, so that, in the rolled state, a turbulence generating section 30 is created. At a location upstream from the turbulence generating section 30, the flat sheet 10 has spaced sections 10-2 free of corrugated sheet, so that, in the rolled state, low flow-resistance sections 22 are created. The dissipation of heat of the exhaust gas is reduced at the sections 22, so that the temperature of the exhaust gas introduced into the turbulence generating section 30 at locations downstream from the low flow-resistance sections 22 is high, thereby promoting an activation of the catalyst at the section 30.

摘要： An electrically heating catalytic apparatus that quickly heats catalyst to an activation temperature even when the engine is started at a low temperature below the catalyst activation temperature. The apparatus employs an electrically conductive catalyst carrier that is electrically heated. The carrier is provided with local hot spots to be energized. Since the heat is locally generated, the heat capacity of the catalyst carrier is small to shorten a temperature increasing time.

摘要： An electrically heated catalytic converter having a substrate for a catalyst, a rod-like metal electrode connected to the substrate, and a casing accommodating the substrate. The substrate for the catalyst is formed as a scroll-like cylindrical laminated assembly of thin metal sheets wound around the electrode. The electrode extends from the laminated assembly along the central axis, bends towards the wall of the casing and penetrates the casing. The electrode is fixed to the casing via an insulating material at the point where it penetrates the casing. When the electricity is fed to the electrode, electric current flows through the electrode to the laminated assembly, and to the casing, and heat is generated in the substrate by the electric current and the temperature of the catalyst carried by the substrate quickly reaches the activating temperature. The rod-like electrode of the present invention is formed as a hollow pipe. Since the heat mass of the hollow pipe electrode is very small compared with the solid metal rod electrode, only a small amount of the heat generated by the electric current is consumed for heating the electrode of the present invention. Therefore, a large amount of the heat generated by the electric current is used for heating the substrate for the catalyst, and the time required for heating the substrate for the catalyst is greatly reduced.

摘要： An ignition device sets a total discharge period, each discharge period and each intermittent period of a multiple discharge are set by a control map in addition to the setting of a throttle opening, fuel injection timing, fuel injection period and ignition timing for the range of non-stratified charge combustion, when a direct injection-type engine operates in the range of stratified charge combustion. Ignition signals including a plurality of rises and falls are outputted in time with a specific ignition timing after fuel injection. Thus a plurality of sparks are generated from the spark plug, ensuring reliable ignition in response to changes in the concentration of sprayed fuel within the operation range for stratified charge combustion.

摘要： A power-saving type of ignition apparatus is provided with a spark plug of which electrodes (30, 40) are regulated in their shapes to lower an amount of energy required for its ignition. To face to a tip (31) of a center electrode (30) extending from a mounting bracket (10), a cylindrical protrusion (41) is built on one surface (43) of an earth electrode (40). The protrusion extends toward the center electrode to form a discharge gap (50) between the protrusion and the tip of the center electrode. Both of the tip of the center electrode and the protrusion of the earth electrode are 2.3 [mm] or less in each diameter (D1, D2), thus an amount of energy required for ignition being limited to 17 [mJ] or less.
