FUEL INJECTORS WITH TORCH IGNITORS
DRIVE
December 18, 2024
A fuel injector (100) includes a fuel nozzle (102) configured to issue a spray of fuel from a fuel outlet (104) in a downstream direction along an injection axis. The fuel nozzle (102) includes a nozzle body (106) that defines a main flow passage (108) therethrough. An injection fuel line (110) is in fluid communication with the fuel nozzle (102) to supply fuel to the fuel nozzle (102). A torch ignitor (112) with a flame outlet (114) opens into the main flow passage (108) of the fuel nozzle (102) for issuing flame into the main flow passage (108). The flame outlet (114) meets the main flow passage (108) at a position that is downstream of the fuel outlet (104) with respect to the downstream direction along the injection axis.
