20140165951 | STRUCTURE TO REDUCE NOISE AND VIBRATION IN AN ENGINE SYSTEM - Adding dome-shaped protuberances, or polydomes, to an engine system increases the structural integrity of the engine component to which they are added and allows noise radiated in the engine system to be reduced in certain regions of the frequency spectrum without incurring a significant increase in the mass of the engine part to which they are added, which may result in a longer solidification time during the mold injection process. The size and spatial arrangement of polydomes relative to one another can be further adjusted to reduce noise within the engine system and polydomes may be reinforced with ribs to increase the structural stiffness of plastic engine components. Because plastic engine components are created using an injection mold process during the manufacturing process, added surface features (e.g. polydomes and ribs) are continuous with the underlying planar surface to which they are added. | 06-19-2014 |

Upon identifying the initial leak, the system substitutes a vacuum-based leak test at each selected interval. The vacuum-based test includes evacuating the system, using the pump. The system then monitors system pressure for a selected period. If system pressure rises above a threshold value during the selected period, then the system identifies a subsequent leak. Upon receiving notification that the initial leak has been repaired, the system returns to pressure-based leak testing. Where a single pump is used, that pump is configured both for system pressurization and evacuation. | 04-02-2015 |
