Abstract
An exhaust manifold includes: an inlet portion which collects exhaust gas discharged through a first to a fourth exhaust ports; an outlet portion discharging the exhaust gas; and a tube portion connecting the inlet and the outlet portions. The inlet portion comprises: a first inlet portion one end of which communicates with the first and the second exhaust ports; and a second inlet portion one end of which communicates with the third and the fourth exhaust ports. Since the inlet portion is provided as two considering the combustion sequence, the productability and the economic feasibility can be enhanced, and the surrounding space can be enlarged to enhance the workability, and a simple exterior appearance can be obtained, and interference between exhaust gases can be effectively prevented, and since the size of the exhaust manifold can be increased, an engine load can be reduced to improve the fuel mileage.
