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 abnormal combustion detection apparatus for an internal combustion engine quickly detects the occurrence of preignition by using a knock sensor. When the knock sensor detects an engine knocking, the ignition timing is delayed. If despite the delay of ignition timing, the knocking is not decreased and the air-fuel ratio detected after the delay of ignition timing is less than the air-fuel ratio detected before the delay of ignition timing, it is determined that preignition has occurred.

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.
