Methods and systems are provided for a fastening assembly. In one example, the fastening assembly includes a vibration dampening element, a two-piece insert, a lower portion, and a fastener configured to engage with the two-piece insert and the lower portion of the assembly. The fastening assembly may be at least partially assembled during manufacture of components to be coupled via the fastening assembly, allowing the components to be readily coupled during final installation of the fastening assembly.

Isolating fastener

A positive crankcase ventilation system for an internal combustion engine routes blowby gases into the intake of the engine. Because the blowby gases have about 12% water vapor, during cold-weather operation, the water vapor may freeze in the PCV valve or in the port that couples the PCV duct with the intake manifold. In situations in which the PCV duct is pointing toward the direction of flow of the intake gases, a hood or cap is placed over the end of the tube according to the present disclosure. It can be as simple as a 90-degree elbow or multiple openings in the cap. A centerline of the openings is perpendicular or at an obtuse angle with respect to the direction of flow in the duct so that the intake gases do not directly access the openings and cause freezing in the openings (or ports).

An engine cover assembly including a fastener concealing plug is disclosed. The plug includes a conical wall having upper and lower ends. A lower circumferential ring is spaced apart from the upper ring. The lower end of the concealing plug includes a fastener-receiving recessed area. The fastener pocket of the engine cover includes upper and lower grooves having a ring area formed therebetween. The upper circumferential ring of the plug nests with the upper groove of the pocket, the recessed area of the plug nests with the ring area, and the lower circumferential ring of the plug nests with the lower groove of the pocket. The engine cover is positioned on the engine such that a cover attaching stud passes through a stud-passing aperture of the cover. A fastening nut is threaded onto the cover-attaching stud until it comes into contact with a compression-limiting spacer. The plug conceals the fastener.

A plural port intake manifold with outlets aligned along a common cylinder head plane and each intake port containing, a valve unit including a valve plate that is rotatable by a shaft along an axis of rotation recessed within an inner wall as well as a welded connection encircling each intake port upstream of the axis. The system may allow the use of a plate CMCV that can fully retract into the intake runner when not in use.

Charge motion control valve and intake runner system

A vehicle incorporates a turbocharged internal combustion engine and a crankcase ventilation system. That crankcase ventilation system includes a first vent line connecting a cam cover at a first spigot to an air inlet duct at a second spigot. In addition the system includes a second vent line connected between the crankcase and the intake manifold of the engine. A one-way valve is provided in the second vent line. A restriction is integrated into either the first spigot, the second spigot or a quick connect that connects the first vent line to the first or second spigot.

A coupling system for attaching a first part to a second part using a locator and expansion shear pin is disclosed. The first part has a first flange and may be a formed part, such as an intake manifold. The second part has a second flange and may be a component, such as a throttle body, for attachment to the first part. The component includes a fastener-passing bore having an inner diameter. The locator and expansion shear pin extends perpendicularly from the first flange. The pin includes an expansion wall extending beyond the surface of the flange. A fastener-receiving bore is formed concentrically in the pin relative to the wall. The wall is expandable from a first diameter to a second diameter. The first diameter is less than the inner diameter of the fastener-passing bore. The second diameter is at least equal to the inner diameter of the fastener-passing bore.

Expansion shear pin for use with thread-forming screw

An internal combustion engine for an automotive vehicle has an intake manifold receiving fresh air via an inlet duct. The engine includes a crankcase. A turbocharger is provided having a compressor with an inlet coupled to the inlet duct and an outlet coupled to the intake manifold. A first vent line couples the crankcase with the compressor inlet. A second vent line couples the crankcase with the compressor outlet and intake manifold. The second vent line has a valve blocking air flow into the crankcase and allowing air flow out from the crankcase. The first vent line comprises a dual-acting valve having a first flow capacity into the crankcase and a second flow capacity out from the crankcase which is greater than the first flow capacity. Thus, crankcase ventilation is optimized for both engine idle and high engine load conditions.

A positioning bracket or a retention bracket to position an actuating arm connected to and at least partially external of an intake manifold, where the positioning bracket includes a body portion to receive there-through a fastener, and an ear portion extending from the body portion and defining an ear aperture to receive there-though a pin of the actuating arm.

Intake manifold retention bracket for long-short runner control

An intake manifold is provided that comprises a plurality of intake manifold runners, and each intake manifold runner comprises at least one elongated riband at least one elongated blister. The elongated riband the at least one elongated blisteroperate together to control structural failure of the intake manifold in an impact event. Specifically, the elongated rib acts to receive and concentrate load while the at least one elongated blister provides an area of intentional failure, thus restricting the failure to a focused area on the intake manifold.

Intake manifold having failure controlling features

In an intake manifold that has charge-motion-control valves (CMCVs), a gap exists between the flapper valves and the wall of the intake runners. Although the gap is maintained as small as practical, it cannot be eliminated because manufacturing tolerances and temperature variations to which the intake manifold is subjected must be accommodated to prevent binding of the flapper valves. Some flow makes an end run through the gap leading to undesirable fluid mechanics. Disclosed herein is a seal that is positioned to rest gently upon the flapper valve near the gap such that the gap is substantially sealed off while applying a modest force on the CMCV so that the actuation torque is minimally impacted. The seal has a press-in-place portion inserted into a pocket formed in the manifold to hold it in place and a lip portion that extends out from the press-in-place portion to obstruct the gap.

Charge motion control valve seal and method of assembly

An apparatus includes an engine assembly and an engine cover. The engine cover includes at least one through hole extending from a top surface to a bottom surface. An appliqu&#xe9; is mounted on the engine cover. The appliqu&#xe9; includes at least one mounting post extending through the at least one through hole. A backing plate is disposed on a bottom surface of the engine cover receiving the at least one mounting post to secure the appliqu&#xe9; to the engine cover.

Engine cover applique backing

A high pressure charge air feed arrangement for an internal combustion engine is provided. The arrangement includes an intake having a high pressure output, a rocker cover having an intake runner defining a high pressure charge flow path, and a gas and oil separator having a flow accelerator with input and output sides. The high pressure output of the intake is attached to one end of the path and the accelerator is attached to the other end. The path is connected between the input and output sides of the accelerator. The separator includes upper and lower plenums divided by a wall having an oil and gas diffuser. The input side is connected to the lower plenum and the output side is connected to a crankcase oil return line. The flow accelerator may be any type of fluid accelerator, including, but not limited to, a venturi pump and a jet pump.

Internal charge air feed from rocker cover integrated intake runners

A crankcase ventilation system for a turbocharged engine has full bi-directional flow for an idle state and a boosted state. A PCV valve provides air flow from the crankcase to the intake manifold in the idle state. A restriction in a first vent line limits fresh air into the crankcase in the idle state. A PCV bypass permits a one-way flow into the crankcase via a second vent line bypassing the PCV valve in the boosted state. A pressure relief valve in communication with the first vent line is configured to bypass the restriction in the boosted state when a pressure in the crankcase exceeds a threshold pressure. In a preferred embodiment, the PCV bypass is configured to bypass both the PCV valve and a pull separator (i.e., oil separator at the second vent line) in the boosted state.
