。[Claims for Utility Model Registration] A nozzle hole 4 is formed in the nozzle hole surface 3 facing the combustion chamber 12 of the nozzle tip 2 of the nozzle body 1, and a heat seal 6 is fitted over the nozzle tip 2. In a diesel engine heat-sealed fuel injection nozzle in which the lip portion 7 of the heat seal 6 is folded back and annularly sealed in contact with the nozzle hole surface 3, the nozzle body 1 is attached to the nozzle hole surface 3 of the nozzle tip 2.
The receiving recess 8 is inserted into the nozzle hole 4 by moving out to the side.
The tip 10 of the lip 7 of the heat seal 6 is fitted into the receiving recess 8, and the outer periphery 7a of the lip 7 of the heat seal 6 is extended to the side wall 5 of the nozzle tip 2. The bottom surface 11 of the part 7 facing the combustion chamber 12 and the nozzle hole surface 3 of the nozzle tip 2 are connected to the inner wall surface 1 of the combustion chamber 12.
3. A fuel injection nozzle with a heat seal for a diesel engine, characterized in that the fuel injection nozzle is configured to be able to be continuously used in a fuel injection nozzle with a heat seal.
