A metal filmis disposed between a permanent magnetand a rotor yoke, and the permanent magnetand the rotor yokeare subjected to beam welding. Since the metal filmis disposed between the permanent magnetand rotor yoke, and the metal filmas a laser beam irradiated portion is melted by vacuum beam or laser beam, the metal filmhas brazing metal function in welding, so that the connection between the permanent magnetand the rotor yokeis strong. Since there is no need of embedding the permanent magnetin the rotor yokeand there is no need to use polymer adhesives, the cost can be reduced.

An internal combustion engine HC-adsorbent is located in one of a pair of exhaust passages in parallel to each other downstream of an emission control catalyst for purifying an exhaust gas and through which exhaust gas flows selectively by a switchover valve. The adsorbent is a zeolite mixture having pores at least 3.5 &#x212b; and smaller than 6 &#x212b; and not equal or larger than 6 &#x212b; and smaller than 7 &#x212b;, and zeolite having pores at least 7 &#x212b; and smaller than 10 &#x212b; and not equal or larger than 6 &#x212b; and smaller than 7 &#x212b;. HCs are desorbed quickly and easily lowering the desorption temperature, while ensuring excellent adsorbing performance for HCs of different molecular diameters. Even when a vehicle travels only a short duration after engine starting, desorption advances quickly and reliably, the adsorbent exhibiting intended adsorbing performance at the next engine starting.

HC-adsorbent for internal combustion engine

An exhaust system comprising a heat-resistant HC adsorbent comprising an MFI metallo-silicate including at least one of gallium (Ga) and indium (In) as a skeleton forming element, and a metal component ME including at least one of an alkali metal and an alkali earth metal in a content of ME&lE;0.05% by weight. Such an HC adsorbent has an excellent heat resistance.

Exhaust system comprising a heat-resistant HC adsorbent

An HC emission control member includes an HC adsorbing layer on a carrier and an HC oxidizing layer on the HC adsorbing layer. The hydrophobic property of the HC adsorbing layer is enhanced, so that satisfactory adsorption and desorption of HC could be obtained.
