SOLUTION: This casing 10 has a cylinder part 13 made of steel plates 11 and 12 overlapped in a plurality of layers. The steel plates 11 and 12 are closely contacted to each other so that they may vibrate and damp by friction between them. The casing 10 is a casing of a catalytic converter 19, and the steel plates 11 and 12 are constituted of inner and outer casings 12 and 11. The overlapped steel plates 11 and 12 are roll molded. The outer casing 11 has a reduced diameter part 22 by drawing and a corner part of the inner casing 12 is cut 16. The inner casing 12 and the outer casing 11 are fixed by spot welding 15 before molding. The inner casing 12 and the outer casing 11 are spot-welded 16 at a casing longitudinal direction center part before welding an abutment part. A recessed part or a projecting part 23 is provided on one of the inner and outer casings 12 and 11. A sound absorbing material 25 is arranged in a gap 24 of the inner and outer casings 12 and 11.

摘要： PURPOSE:To suppress interference between inner and outer pipes in a double exhaust pipe having a bent portion by eliminating extention at an inlet of exhaust gas before reaching the bent portion, and thereby suppressing shifting of the bent portion of the inner pipe. CONSTITUTION:A sliding portion 22 is formed on an upstream end of a bent portion 20 of an inner pipe 4 and a part between the inner pipes 4 and 6. A sliding portion 26 is formed on a downstream end of the bent portion 20 of the inner pipe 4, and a part between the inner pipe 4 and an outer pipe 2 of a straight portion 18 in the vicinity of an outlet 10 for exhaust gas. Thermal expansion difference between the inner pipes 4, 6 in the longitudinal direction of a straight portion 16 and the outer pipe 2 is eliminated by the sliding portion 22 on the upstream end of the bent portion 20 of the inner pipe 4 including the bent portion 20. Thermal expansion difference between the inner pipe 4 in the longitudinal direction of the straight portion 18 and the outer pipe 2 is eliminated by the sliding portion 26 on the downstream end of the bent portion 20 of the inner pipe 4 including the bent portion 20. Interference between the inner pipe 4 and the outer pipe 2 is hard to occur at the bent portion 20 and generation of abnormal noises is reduced.

摘要： PURPOSE:To reduce the quantity of exhaust HC in a cold time, by promoting the atomization of fuel in a dual intake type internal-combustion engine provided with an electron control fuel injection device. CONSTITUTION:The main intake passage 28 of siamese type and a subordinate intake passage 30 are provided, and a fuel injector 36 is provided on the main intake passage 28. An assist air pipeline 42 supplying assist air for promoting the atomization of fuel is provided near the injection port 36a of the injector 36. The fuel is atomized by the assist air introduced from the assist air pipeline 42 into an adapter 56 via an assist air intake port 56a. Thereby the particle size of the fuel injected from the injector 36 is minimized, and thus the supply of the fuel to each cylinder becomes smooth.
