Abstract
A cylinder head with which exhaust manifolds are integrated includes a secondary air supply passage configured to include: a main passage disposed above combustion chambers of an engine, and extending along a cylinder line direction; and plural branch passages establishing individual communications between the main passage and corresponding exhaust ports. The respective plural branch passages are so disposed as to be inclined downward from the main passage toward the exhaust ports. Accordingly, it is possible to prevent corrosion of the cylinder head due to stagnation of condensed water.
