Claims

[Scope of utility model registration request]

The center of the straight line connecting the center of the intake port and the center of the exhaust port in the cylinder head of a diesel engine where a water jacket is formed and multiple bolt holes are formed for passing bolts for tightening and fixing to the cylinder block. A cooling water passage located on a straight line substantially perpendicular to this straight line at a portion and communicating with the front water jacket at one end is drilled in a bridge portion formed between the intake port and the front exhaust port, The other end side of the cooling water passage is located between a communication portion between a waterway formed in the cylinder block and communicating with the water jacket and the cooling water passage, and an intersection between the cooling water passage and the bolt hole. A cylinder head cooling device for a diesel engine, characterized in that a blank seal is press-fitted to seal the cylinder head.
