摘要： [과제] 내구성이 보다 우수한 회전날개부재 및 그의 제조방법을 제공한다.
[해결수단] 인장 잔류응력이 남아있는 임펠러(21)를 통상의 사용회전속도 보다 빠른 회전속도로 회전시킨다. 그리하면 임펠러(21)의 내부의 고응력(高應力)발생부(24)가 원심력(F)에 의하여 소성(塑性)변형된다. 이것에 의해 회전을 정지한 후에는 고응력발생부(24)에 압축잔류응력이 잔류(殘溜)하여 인장(引張)잔류응력이 제거된다. 따라서 고응력발생부(24)에 걸리는 반복인장응력을 경감하여 내구성이 보다 우수한 임펠러(21)를 제공한다.

摘要： PURPOSE: A turbocharger is provided to transmit energy of exhaust gas to a turbine wheel efficiently with compact structure, and to prevent exhaust interference by flowing together after increasing the flow rate of backward and forward exhaust gas. CONSTITUTION: A turbocharger is composed of an exhaust inflow passage(19) flowing exhaust gas into a turbine wheel(14), and the exhaust inflow passage is composed of an induction unit linearly formed in the inlet of exhaust gas, a scroll part surrounding the turbine wheel annularly and a tongue part formed in the rear end of the scroll part and arranged linearly in the inlet of exhaust gas. The induction unit comprises a partition part(79) dividing the exhaust inflow passage into the first exhaust inflow passage and the second exhaust inflow passage from the inlet to the downstream part, a tightening part having the sectional area narrowed from the inlet to the end of the partition part, a conflux part joining exhaust gas of the first and second exhaust inflow passages, and a diffuser unit having the sectional area expanded from the conflux part to the tongue part.

摘要： PURPOSE: To provide an exhaust gas purifying device for an internal combustion engine, having improved inherent function by increasing the capacity of all carriers and eliminating the need for a larger arrangement space. CONSTITUTION: The exhaust gas purifying device 1 comprises the carriers 34 arranged in series along the flowing direction of exhaust gas, the upstream carriers 34 being adapted to admit approximate half of exhaust gas passing through a first distribution passage 4, and the downstream carriers 34 being adapted to admit the remaining half of exhaust gas passing through a second distribution passage 5. Thus, the whole capacity of the pair of carriers 34 is approximately doubled, achieving the improved purifying efficiency. The exhaust gas from the distribution passages 4, 5 is combined in a combination chamber 21 and exhausted through one outlet pipe 22. As a result, an increase in cross section of each carrier is suppressed by series arrangement, one outlet pipe 22 helps reducing the size and a smaller arrangement space is required.
