ノズル。 In a fuel injection nozzle that directly injects fuel into the combustion chamber of a diesel engine, the nozzle body of the fuel injection nozzle has two holes of different sizes and sizes.
The height from the tip of the nozzle body to the upper surface of the small nozzle on the inner wall side of the nozzle body is the same as the height from the tip of the nozzle body to the lower surface of the large nozzle on the inner wall side of the nozzle body. A fuel injection nozzle characterized in that the large injection port and the small injection port are arranged so as to be lower than the height.
