摘要:
In a metal catalyst converter configured of the metal catalyst carrier that holds the catalyst into the honeycomb body created by alternately winding flat sheet and corrugated sheet, a plurality of slit matrix that extend in the direction perpendicular to the exhaust gas direction were arranged on at least one part of the upstream side of the exhaust gas passage. By that a low heat capacity and high heat transfer area in regard to the downstream side of the exhaust gas passage was formed. The upstream portion of the metal catalyst converter on which slit matrix was formed was configured to be covered by outer casing having an air insulation layer. The upstream side of this outer casing was held and fixed to the exhaust gas passage.

It is the primary object of the present invention to provide a catalyst converter which can hold a sufficient amount of catalyst to raise the temperature thereof to the catalyst activation temperature in a short time without enlarging the metal carrier itself. The metal carrier 1 is arranged in the course of an exhaust manifold 3 of an engine 2 and is composed of an alternating winding of a flat sheet 7 and a corrugated sheet 8, wherein slit parts 9 are formed in the flat sheet 7 and the corrugated sheet 8 of the metal carrier 1 in an end portion thereof, on the side the engine 2.

A self-heat generating type honeycomb filter is mounted in an exhaust pipe line of an engine, and a plane plate and a corrugated plate are layered, then wound, and the first slit portion and second slit portion having openings, respectively, are formed between an up-stream and down stream side end portions of the plane and corrugated plates. An electric current is applied between the up-stream and down stream side end portions, to heat the first and second slit portions. Accordingly, a self-heat generation type catalytic converter capable of realizing both high resistance and low thermal capacity, and further ensuring a reduction in thermal conduction, and durability, and raising the temperature up to the sufficient level with less power consumption, can be provided.

A problem has been resolved by providing a folding cell phone having a position detecting unit which detects the coupling state between the first frame part and the second frame part and a communication controlling unit which performs processing to control enabling or disabling of the configuration to stop the functions necessary for communication only, according to the results of detection by the position detecting unit.
摘要:
Pressurized fuel of a common rail is introduced into a control chamber of a fuel injector. An electromagnetic valve opens or closes a fuel discharge passage of the control chamber to adjust a hydraulic pressure of the control chamber. Through a switching leak passage, bubble-containing fuel directly returns from a valve opening of the electromagnetic valve to a low-pressure return passage without passing through an armature chamber. Through a stationary leak passage, the fuel leaking from every slide portion returns to the return passage via the armature chamber. A downstream portion of the stationary leak passage opens to the upper portion of the armature chamber. A damper element is provided downstream of the electromagnetic valve in the return passage for canceling an increased fuel pressure.

In a fuel injection valve, a flow-out passage is provided on a downstream side thereof with an out-orifice. The out-orifice is provided around a periphery of an inlet opening thereof with an inlet circumferential edge with which a flow of fuel to be ejected from a pressure control chamber via the out-orifice is swirled so that turbulent flow is forcibly formed. Then, the turbulent flow is maintained until the fuel is ejected. Dimensions of the out-orifice satisfy the formulas, R/D≦0.2 and L/D≦1.2, where R is corner radius of the inlet circumferential edge of the out-orifice, D is inner diameter thereof and L is axial length thereof. Accordingly, fuel injection is stable with less fuel amount fluctuation in each cycle even when fuel pressure and temperature are relatively low.

摘要:
A honeycomb structure body has a honeycomb base body and a pair of electrodes composed of conductive ceramic layers and intermediate layers. The honeycomb base body made of porous ceramics containing SiC is comprised of a cell formation part and an outer peripheral part. The outer peripheral part covers the cell formation part. Each electrode is comprised of a conductive ceramic layer and an intermediate layer. The conductive ceramic layers containing SiC, Si and C are formed at two opposite positions on the outer peripheral part observed from a diameter direction. The intermediate layers containing SiC, Si and C are formed in the outer peripheral part at the parts which face the conductive ceramic layers. The honeycomb structure body satisfies a relationship of 0.5≦t/T≦1, where “t” indicates the thickness of the intermediate layer and “T” indicates the thickness of the outer peripheral part.

A so-called internal intermediate pressure multistage compression type rotary compressor makes it possible to prevent the pressure inside a roller from inconveniently increasing and also to permit smooth and reliable supply of oil into a cylinder of a second rotary compressing element by a relatively simple construction. A lubrication groove for providing communication between an oil bore and a low-pressure chamber in the cylinder is formed in a surface of an intermediate partitioner that is adjacent to the cylinder of the second rotary compressing element. Furthermore, a through bore for providing communication between a hermetically sealed vessel and the inside of the roller is formed in the intermediate partitioner.
摘要:
In a manufacturing method of producing ceramic honeycomb structure bodies, an extrusion molding step extrudes a ceramic raw material to make a ceramic honeycomb molded body having an outer peripheral skin part, plural cell walls arranged in a honeycomb structure shape, and plural cells surrounded by the cell walls. A cutting step cuts the ceramic honeycomb molded body into plural ceramic honeycomb shaped bodies of a predetermined length. A drying step dries each ceramic honeycomb shaped body, and a working step cuts and removes the outer peripheral part thereof. A burning step burns the worked ceramic honeycomb shaped bodies to produce the ceramic honeycomb structure bodies. In the working step, a cutting tool for blanking having a cutting tooth formed at a front part thereof is relatively moved in the axis direction of the ceramic honeycomb shaped body in order to cut and remove the outer peripheral part including at lease the outer peripheral skin part.
