发明名称 MANIFOLD FOR INTERNAL COMBUSTION ENGINE
摘要 <p>PURPOSE:To prevent generation of cracks by suppressing application of stress caused by difference between input oscillations. CONSTITUTION:An exhaust manifold 1 is provided with branched portions 3A, 3B, 3C and a main body 4. Inlet side flanges 5A, 5B, 5C installed on a cylinder head 2 is arranged respectively on the edges of the branched portions 3A, 3B, 3C. An outlet side flange 6 connected to an exhaust pipe 7 is arranged on an edge of the main body 4. The inlet side flange 5A is integrated with the outlet side flange 6. Oscillations are transmitted to the exhaust manifold 1 from the cylinder head 2 and the exhaust pipe 7 at the time of running. Oscillations transmitted from the cylinder head 2 and the exhaust pipe 7 to the exhaust mainfold 1 respectively through the inlet side flange 5A and the outlet side flange 6 have the same phase. Application of stress is suppressed, which may be caused by oscillation difference.</p>
