The utility model discloses a camshaft cavity of a diesel engine cylinder body. The camshaft cavity is arranged on the side surface of a cylinder hole of the diesel engine cylinder body; on the cross section, penetrating through the center of a camshaft, of one cylinder of the diesel engine cylinder body, the inner contour, close to one side of the cylinder hole of the cylinder, of the camshaft cavity of the diesel engine cylinder body is a square surface; on the longitudinal section, penetrating through the center of the camshaft, of the cylinder, the inner contour is conformal to the inner wall, close to the inner contour, of the cylinder hole of the cylinder so as to form an arc-shaped surface. According to the camshaft cavity of the diesel engine cylinder body, the inner contour, close to one side of the cylinder hole, of the cavity is designed to be conformal to the inner wall, close to the inner contour, of the cylinder hole, so that the wall thickness between the cylinder hole and the camshaft cavity is uniform and the local wall thickness can be reduced, the weight of the cylinder body can be effectively reduced, and the weight of a whole engine can be further lowered, thus further meeting the lightweight requirement of the engine.
