Abstract: PURPOSE: An exhaust manifold of an engine is provided to restrict or properly absorb thermal transformation around the junction part of an exhaust manifold. CONSTITUTION: An exhaust manifold of an engine comprises fastening flanges(5), coupling flanges(3), a reference hole(7), and a thermal deformation prevention hole(9). The fastening flanges are formed on the top and bottom of ports(15,17,19,21,23) and fastened to a cylinder head with bolts. The coupling flanges form a vertical plane perpendicular to the fastening flanges. The reference hole, which serves as assembly reference during assembly of an exhaust manifold, is formed in one of the fastening flanges. The thermal deformation prevention hole is formed in the fastening flange which is vertically symmetrical with the fastening flange in which the reference hole is formed. The thermal deformation prevention hole is formed to be larger than the reference hole but to prevent the thermal transformation of the exhaust manifold.

CONSTITUTION: A bypass channel(10) is installed in a case(1) to guide exhaust gas to pass a carrier(4) and detour so as to be discharged. The bypass channel is placed in the case, and directly connects an inlet(2) and an outlet(3) of the case so that some of exhaust gas introduced through the inlet is directly discharged through the outlet without passing the carrier. An opening and closing unit(11) is installed to an inlet of the bypass channel to be selectively opened and closed depending on strength of exhaust pressure, and comprises a valve body(12) and a spring(13). The valve body opens and closes the inlet of the bypass channel, and has one side hingedly coupled to a wall of the case to allow the valve body to rotate. The spring is formed on an axis of the valve body to elastically press the valve body in closing direction.
