Definitions
- the invention relates to a fuel injection nozzle with a cooling channel arranged in the combustion chamber end region of the housing.
- the invention has for its object to achieve good cooling of the thermally highly stressed areas of the injection nozzle.
- cooling channel is arranged closer to the nozzle needle bore than to the outside of the housing and has a cross-sectional area whose width is at most equal to the height extending in the axial direction of the nozzle.
- the width of the cooling channel is advantageously 0.1 to 0.9 times the height. According to a preferred embodiment, the width of the cooling channel is approximately 0.25 times the height.
- the cooling duct preferably extends on the combustion chamber side to the height of the nozzle needle seat.
- the nozzle has a housing 1, in which a nozzle needle bore 2 with a nozzle needle seat 3 is arranged along its axis A-A.
- the nozzle needle bore 2 merges into a fuel storage space 4, which leads to injection bores 5 projecting into the combustion chamber (not shown).
- a cooling duct 6 is arranged in the housing 1.
- the width of this cooling channel is approximately 0.25 times the height extending in the direction of the axis A-A. It generally applies to the cooling duct 6 that the width should at most be equal to the height.
- the width should preferably be selected in a range from 0.1 to 0.9 of the height.
- a cooling duct designed in this way can be pulled down close to the combustion chamber and thus into the end region of the nozzle which is subjected to the greatest thermal stress.
- a large wall surface 8 of the cooling channel 6 facing the inner region of the nozzle is available for the heat transfer to the cooling water.
- the cooling channel 6 is supplied with coolant through a coolant supply line 7.
- the cross-sectional area of the cooling channel 6 is approximately twice the cross-sectional area of the coolant supply line 7. This achieves a relatively high flow rate of the coolant and thus a large amount of heat dissipation. Dead water areas are also avoided with this construction.
