Fuel injection device
Document Type and Number:
Japanese Patent JP5988261
Kind Code:
B2
Abstract:
A fuel injector includes a pilot fuel injector, configured to inject the fuel into a combustion chamber, and a main fuel injector provided coaxially with the pilot fuel injector so as to surround the pilot fuel injector and configured to have a main flow path to generate a premixed air-fuel mixture. The main flow path includes an outer main air passage located radially outwardly and configured to supply a compressed air in an axial direction into an annular premixed air-fuel mixture passage, an inner main air passage located radially inwardly and configured to supply the compressed air into the premixed air-fuel mixture passage from a radially inner side. The injector further includes a main fuel injection port to inject the fuel from an axially upstream side into the inner main air passage.
