The utility model discloses an engine exhaust manifold. The engine exhaust manifold comprises an exhaust manifold body, wherein the exhaust manifold body is composed of a transverse pipe section and a sloped pipe section which is upward inclined and curved through successive connection, the end part of the transverse pipe section is provided with an air inlet flange connected with a connecting end surface of a cylinder cover, and the end part of the sloped pipe section is provided with an air outlet flange connected with a supercharger connecting end surface. The engine exhaust manifold provided by the utility model has the advantages that the vertical distance from the top surface of the air outlet flange to a center line of a transverse pipe is shortened, the height of the air outlet flange of the exhaust manifold is reduced, and an included angle arranged between the flat surface where the end surface of the air outlet flange is located and the flat surface where the end surface of the air inlet flange is located is an acute angle; an included angle formed by the transverse pipe section and the sloped pipe section is an obtuse angle, the height of a supercharger connected with the air outlet flange of the exhaust manifold is reduced, and the compatibility of an engine and a vehicle is improved.
