A catalytic device that can increase the durability of a catalyst support with holes is provided. A flat plate and a corrugated plate have a plurality of holes, a joint area between the flat plate and the corrugated plate is provided in a first upstream area including one end of a catalyst support, and a joint area between the catalyst support and an outer cylinder is provided in a second upstream area that includes the first upstream area and is wider than the first upstream area in the direction of an axis.

Catalytic device

In an exhaust-gas-purification catalytic heating device that houses a current heater in a conductive metallic housing where a catalytic unit is housed, the current heater being arranged at an upstream side of the catalytic unit along a distribution direction of exhaust gas, the current heater has a negative electrode directly coupled to the housing electrically coupled to an external ground wire, the current heater has a positive electrode with which a rod-shaped terminal is continuous, the terminal passing through the housing in an electrically insulating state so as to be electrically coupled to a power line outside the housing, and the terminal has a portion protruding from the housing, the protruding portion being covered with a terminal cover.

A metal honeycomb structure includes planar and corrugated sheets brazed together at first and second joining portions made of brazing materials applied to the corrugated sheet. The first and second joining portions are located proximate exhaust inlet and outlet of the honeycomb structure. The honeycomb further includes a joining strip joined to a metal outer tube. The joining strip is made of a brazing material applied to an inner wall of the metal outer tube. The second joining portion overlaps the joining strip and has a brazing length larger than a brazing length of the first joining portion which does not overlap the joining strip.

It is devised to further enhance strength and straightening ability of a nitrocarburized raw material for crankshafts. A nitrocarburized raw material for crankshafts is formed so as to have a composition composed of C, Si, Mn, Cu, Ni, Cr, V, S, s-Al, Ca and N in prescribed % by mass, with the balance being Fe and inevitable impurities and having a structure of ferrite+pearlite; after smelting a steel having the foregoing composition, hot forging is performed; thereafter, a normalizing treatment is applied to the subject hot forged material at a treatment temperature in the range of from 780&#xb0; C. to 850&#xb0; C.; and straightening process for correcting bending to be caused due to the nitrocarburizing treatment is later applied.
