造。It is a same flow type in which the intake port and exhaust port open on one side of the cylinder head, and the intake port diameter is larger than the exhaust port diameter, and the exhaust port wall is centered between the cylinder bores with respect to the intake port wall. In the cylinder head structure of an adjacent engine, among the cylinder head bolt bosses provided on both sides of the cylinder head corresponding to the center between the cylinder bores, the bolt boss is provided on the side opposite to the side of the cylinder head where the above-mentioned intake and exhaust ports open. The cylinder head bolt boss portion and the adjacent intake and exhaust port walls of the cylinder loading deck portion are connected by a substantially triangular rib, and the rib faces toward the center between the intake port wall and the exhaust port wall. What is claimed is: 1. A cylinder head structure for an engine, characterized in that the cylinder head is inclined at a predetermined angle toward an intake port with respect to a direction perpendicular to a cylinder row.
