The cylinder head includes an ignition plug wall surrounding a bore configured to receive an ignition plug, where the ignition plug wall is integral to the cylinder head, the bore has a diameter, and the ignition plug wall has a thickness. The cylinder head also includes a cooling cavity completely separated from the bore via the ignition plug wall, where the cooling cavity has a radial width relative to an axis of the bore. The cylinder head further includes at least one of a first ratio of a minimum of the thickness versus a minimum of the diameter less than approximately 0.5 or a second ratio of a minimum of the radial width versus the minimum of the diameter less than approximately 0.5, or a combination thereof. | 02-18-2016 |
| 20160076480 | VALVE SEATS FOR CYLINDER HEADS IN AIRCRAFT ENGINES - Intake and exhaust valve seat inserts for aircraft cylinder heads. The inserts are configured for low pressure loss as inlet air and hot exhaust gas passes through the respective valve seat inserts. In an embodiment, the intake and exhaust valve seat inserts may have a plurality of faces or facets, at prescribed angles, in order to minimize pressure loss of gases passing therethrough. In an embodiment, rather than a plurality of faces or facets, the intake valve seat sidewall, and/or the exhaust valve seat sidewall may be provided in the configuration of a smooth curve approximating a set of selected angles, as if the component were made with a plurality of facets. | 03-17-2016 |
| 20160084196 | ENGINE RADIATION NOISE REDUCTION STRUCTURE - An engine radiation noise reduction structure is provided. The engine radiation noise reduction structure includes a coating layer configured to absorb noise emitted from an engine and is formed on a high-temperature noise radiation part. The high-temperature noise radiation part includes an engine cover. In addition, coating layer includes polyamide imide resin and aerogel dispersed within the polyamide imide resin. | 03-24-2016 |
