    Abstract: A ventilator (100) for ventilating an airway (112) of a patient is generally configured to perform a series of respiration cycles, wherein each respiration cycle includes the delivery of a main volume of fresh respiratory gas into the patient's airway (112), followed by the evacuation of a corresponding volume of used respiratory gas, and to further perform a series of subcycles during a corresponding one of the respiration cycles, wherein each subcycle includes the delivery of an auxiliary volume of fresh respiratory gas into the patient's airway (112), followed by the evacuation of a corresponding volume of used respiratory gas, the auxiliary volume being smaller than, and distinct from, the main volume.

    Abstract: An assembly for a powerplant includes a housing (34), a primary fuel injector (38) and an ignition system (40). 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.

    Abstract: During a manufacturing method, a protective coating (112) is applied to a first chamber surface (114) of a first component (102) to provide a coated first chamber surface (114') and to a second chamber surface (116) of a second component (104) to provide a coated second chamber surface (116'). The second component (104) is configured with the first component (102) to provide a pilot chamber structure (68). The pilot chamber structure (68) includes a pilot chamber (74), a pilot aperture (76), a fuel aperture (92) and an ignitor aperture (94). The pilot chamber (74) is formed by the coated first chamber surface (114') and the coated second chamber surface (116') within the pilot chamber structure (68). The pilot aperture (76) projects into the first component (102) from a distal end of the pilot chamber structure (68) to the pilot chamber (74). The fuel aperture (92) projects into the pilot chamber structure (68) to the pilot chamber (74). The ignitor aperture (94) projects into the pilot chamber structure (68) to the pilot chamber (74).
