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.
