Abstract
During a manufacturing method, a protective coating is applied to a first chamber surface of a first component to provide a coated first chamber surface. The protective coating is applied to a second chamber surface of a second component to provide a coated second chamber surface. The second component is configured with the first component to provide a pilot chamber structure. The pilot chamber structure includes a pilot chamber, a pilot aperture, a fuel aperture and an ignitor aperture. The pilot chamber is formed by the coated first chamber surface and the coated second chamber surface within the pilot chamber structure. The pilot aperture projects into the first component from a distal end of the pilot chamber structure to the pilot chamber. The fuel aperture projects into the pilot chamber structure to the pilot chamber. The ignitor aperture projects into the pilot chamber structure to the pilot chamber.
