The housing (34) forms a combustion volume (66) within the housing (34). The primary fuel injector (38) is configured to inject primary fuel into the combustion volume (66). The ignition system (40) is configured to ignite the primary fuel within the combustion volume (66). The ignition system (40) includes a pilot fuel injector (70), a pilot ignitor (72), a pilot chamber (74), a first component (78) and a second component (80). The pilot fuel injector (70) is configured to inject pilot fuel into the pilot chamber (74). The pilot ignitor (72) is configured to ignite the pilot fuel within the pilot chamber (74). The pilot chamber (74) is fluidly coupled with the combustion volume (66) through an aperture in the first component (78). The pilot chamber (74) is formed by and disposed between the first component (78) and the second component (80). The first component (78) is configured from or otherwise include a ceramic.",
