Abstract: A self-retaining gasket including a main body, a first retention tab, and a second retention tab. The main body includes a first surface and a second surface opposite to the first surface. The main body defines a first aperture extending between the first surface and the second surface. The first retention tab and the second retention tab extend from the main body at the first aperture.

Abstract: A speed nut for fastening a work piece to a stud includes a fastener plate defining an opening on a surface. The speed nut further includes a prong extending inwardly from an edge of the opening, the prong includes a root portion connecting with the fastener plate and a terminal end defining a single-threaded hole within the opening and configured to ratchet over threads of the stud. The root portion and the terminal portion are arranged offset from each other such that the prong plastically deforms in response to the work piece being removed from the stud.

Abstract: A housing has an outer pipe, an inner pipe, and an EGR inlet. The inner pipe is located inside the outer pipe. The inner pipe defines an inner passage internally. The inner pipe defines an annular passage externally with the outer pipe. The EGR inlet defines an EGR channel therein to communicate with the annular passage. The inner pipe has an end surface defining a throttle passage extending circumferentially. The throttle passage communicates the annular passage with the inner passage radially inward. The throttle passage is narrow on a side of the EGR channel and is wide on an opposite side of the EGR channel.

Abstract: A dedicated exhaust gas recirculation (EGR) system. The EGR system includes a plurality of flow restriction devices, each one of which is associated with a different one of a plurality of EGR conduits leading to air runners of an air manifold in order to control delivery of exhaust gas to the air runners. The air runners are configured to direct air and exhaust gas to the engine cylinders.

Abstract: A compression limiter for limiting compressive force applied by a fastener when fastening a component to a body. The compression limiter includes a sleeve and a diaphragm. The sleeve is formed in a cylindrical shape with openings at both ends. The diaphragm is coupled to an inner surface of the sleeve. The diaphragm is deformable between a first configuration and a second configuration. The first configuration defines a slit on the diaphragm with a width less than a diameter of the fastener. The second configuration expands the slit according to the diameter of the fastener so that the fastener is retained within the sleeve because of an elastic force applied by the diaphragm.
