ダヘツド。 In a cylinder head of a diesel engine that has a pre-chamber, two intake holes, and one exhaust hole, an intake port and an exhaust port are formed on one side of the main center line in the cylinder arrangement direction, and the main center line is The exhaust hole and the first intake hole are arranged on both sides of the sub-center line for each cylinder, which is slightly offset to the non-port side and perpendicular to the main center line, and the first intake hole is closer to the side of the sub-center line than the sub-center line. A second intake hole is placed at a slightly offset position and on the port side from the main center line, and a sub-chamber is placed at a position on the non-port side, and a water-cooling jacket is formed around the sub-chamber while exhaust is exhausted from the other side. A cylinder head for a diesel engine, characterized in that a drilled passage formed to pass between a hole and a second intake hole is connected to a water cooling jacket.
