Abstract
The proposed solution relates to a fuel nozzle for the injection of hydrogen into a combustion chamber of an engine, the fuel nozzle including, for provision of a hydrogen-air mixture, a nozzle head having outflow openings (19, 21) at an end face of the nozzle head. Multiple first outflow openings for hydrogen to be injected and at least one second outflow opening for air to be injected are present at the end face for the provision of the hydrogen-air mixture, where the at least one second outflow opening has a polygonal cross section and the multiple first outflow openings at the end face are arranged around the at least one second outflow opening.
Claims16
A fuel nozzle for injection of hydrogen into a combustion chamber of an engine, said fuel nozzle comprising, for provision of a hydrogen-air mixture,
- a nozzle head having outflow openings at an end face of the nozzle head,
- wherein multiple first outflow openings for hydrogen to be injected and at least one second outflow opening for air to be injected are positioned at the end face for the provision of the hydrogen-air mixture, where the at least one second outflow opening has a polygonal cross section and the multiple first outflow openings at the end face are arranged around the at least one second outflow opening;
- wherein the end face of the nozzle head is quadrangular or rectangular.
A fuel nozzle for injection of hydrogen into a combustion chamber of an engine, said fuel nozzle comprising, for provision of a hydrogen-air mixture,
- a nozzle head having outflow openings at an end face of the nozzle head,
- wherein multiple first outflow openings for hydrogen to be injected and at least one second outflow opening for air to be injected are positioned at the end face for the provision of the hydrogen-air mixture, where the at least one second outflow opening has a polygonal cross section and the multiple first outflow openings at the end face are arranged around the at least one second outflow opening;
- via at least one additional outflow opening formed between the nozzle head and an edge of the passage opening, the air can flow past the nozzle head into a combustion space of a combustion chamber;
- wherein the at least one additional outflow opening is formed by a gap having a longitudinal extent with regard to the end face of the nozzle head and running along a section of an outer circumference of the nozzle head.
