摘要： An engine induction system resonator that is designed to minimize emitted engine noise. The resonator includes an enclosed tube that has a first diameter and that defines a resonant chamber therein. The resonator also includes a pipe that has a second diameter smaller than the tube diameter. The pipe extends axially through the tube and has first and second ends that connect to other induction system components to channel inductive air flow therethrough. The pipe defines a plurality of perforated holes distributed along a section of the pipe housed within the tube. The plurality of perforated holes is distributed along the pipe in a manner that minimizes emitted engine noise. The resonator is designed in view of other system components to minimize overall system cost and overall required system implementation area.

摘要： A method of minimizing engine noise emitted from a motor vehicle air intake system. An objective function to be minimized, such as emitted engine noise, is selected. A model of a motor vehicle engine and intake manifold as an acoustic source is generated. Next, a model of required air induction system components is generated. A set of air induction system components and system dimensional constraints is selected. A model of the air induction system is then created given the generated models of the acoustic source and the required induction system components, the selected air induction system components and the system dimensional constraints to thereby minimize the objective function. The methodology of the present invention minimizes the guesswork associated with multi-component induction system design, as it ties all functions together into a model that can be easily manipulated as needed in response to changing design parameters.

摘要： In a fastened joint where two or more joint members are secured together, a method for improving the sealing properties of the joint. The method includes the incorporation of one or more depressions into at least one joint surface of the joint members. The depressions are positioned to reduce the tendency of the joint members to transmit clamping forces between non-sealing areas, thereby increasing the magnitude of the clamping forces transmitted through sealing areas and reducing the opportunity for leakage.

摘要： A hydraulic lash adjuster for an engine is provided that includes a resilient seal received over a plunger assembly above a fluid return aperture in the plunger body. The hollow interior of the pushrod which supplies the hydraulic lash adjuster with fluid provides a secondary low pressure fluid cavity which allows the overall length of the hydraulic lash adjuster to be shortened, thus removing mass from the valve train and improving the valve train dynamics. This configuration prevents fluid from escaping the lash adjuster, allowing the lash adjuster to be positioned in the engine over a wider range of operating angles. Supplying fluid from the pushrod also eliminates the need to machine a fluid supply bore into the body of the hydraulic lash adjuster as well as the need to orient the fluid supply bore to a fluid gallery in the engine block.

摘要： A cylinder bore liner insert configured to be cast in an internal combustion engine block includes an additive manufactured liner wall formed during an additive manufacturing process and having an inner surface, an outer surface, and an upper surface configured to be operably associated with a cylinder head, wherein the inner surface at least partially defines a cylinder bore configured to receive a piston therein. A liner water jacket is defined internally within the additive manufactured liner wall during the additive manufacturing process. The liner water jacket at least partially surrounds the cylinder bore to provide cooling thereto via a flow of coolant within the liner water jacket. A plurality of coolant ports are formed in the upper surface and configured to enable flow of coolant between the liner water jacket and the cylinder head.
