An apparatus and method compressibly secure together a plurality of components, wherein some of the components may include plastic or other materials susceptible to creep. The apparatus includes a plurality of stackable compression limiters configured to engage axially end to end in tandem and in some aspects to lockably engage. Each stackable compression limiter includes an elongated sleeve member configured to limit the maximum compressive force applied to its associated component, where different components in the stacked assembly may be configured for different maximum compressive forces.

An active intake manifold system includes at least one flap cartridge assembly having a unitary cartridge housing including one or more flap valve housings. A flap valve is rotatable in the aperture of the flap valve housing between an open state and a closed state. A shaft is provided extending through the mounting ear apertures of the flap valves so that the flap valves change state in unison. A plurality of air intake runners provides air flow communication between the outlets of the flap valve housings and the cylinder intake valves of the engine. Each intake runner includes a main runner portion that then splits into a plurality of tracts of differing lengths with each tract tuned to a different predetermined engine speed and having a length and volume selected to optimize engine performance at the predetermined speed. The flap valves may be automatically operated by an actuator under control of an engine control system.

A lower intake manifold assembly includes a lower housing and a runner insert fitted into the lower housing. The lower housing may be made of metal and the runner insert may advantageously be made of a synthetic resin material. The runner insert provides a sealing surface between the lower housing and the cylinder head of an internal combustion engine. The runner insert also supports a charge motion control valve flap assembly that advantageously may include a shaft and synthetic resin flaps over-molded onto the shaft.

An integrated positive crankcase ventilation (PCV) channel is formed along a structural weld line between two shell components that are welded together to form an air intake manifold. The integrated PCV channel can be used to uniformly distribute blow-by gases from the crankcase of an internal combustion engine to a plurality of combustion chambers via the air intake manifold.

An air intake manifold assembly includes an air intake manifold and a insert that is permanently bonded to an inner surface of the air intake manifold. By bonding the insert to the manifold, a dead space is formed between the insert and the manifold, which reduces the plenum volume within the manifold.

An intake manifold system for an international combustion engine includes an engine intake manifold having a valve; and an actuator connected to the valve to control valve opening. The actuator is connected to a pressurized coolant reservoir of the engine to allow the use of the pressurized fluid of the coolant reservoir to operate the actuator.

Engine intake manifold system

An air intake manifold assembly for an internal combustion engine composed of a plurality of molded synthetic resin shells assembled to each other so as to define a plenum chamber, a plurality of inlet channels leading from said plenum chamber to cylinder inlets of the internal combustion engine, and a throttle body passageway leading from a throttle body mount into the plenum chamber; with a groove formed in a surface of at least one of the shells facing an adjacent shell and extending from an inlet opening to the throttle body passageway or the plenum chamber so as to form an elongate passage between the assembled shells leading from the inlet to the throttle body passage or plenum chamber, and a method of forming such an intake manifold assembly.

A plastic transmission filter () composed of mating upper () and lower () shells of synthetic resin material with at least one set of registering weld posts () extending between inner surfaces of the upper and lower shells; a fluid pervious centertube () interposed between the mating shells around the weld posts, and a filter material () wrapped around the centertube to form a bag filter. The filter assembly can be welded together in a single vibration welding operation and provides enhanced flow of transmission fluid by avoiding flow restrictions caused by prior art reinforcement poles.

An engine intake manifold includes a casing having a plurality of air intake passages, and a plurality of valve plates, wherein each valve plate is disposed in one of the air intake passages to control airflow through the air intake passage. The valve plates are connected to a common valve shaft for rotation between an open position and a closed position. The engine intake manifold may further include an actuator that is mounted to the casing or to the valve shaft via a snap connection, and is rotationally connected to the valve shaft to allow the actuator to rotate the valve shaft.

A method for making a lower intake manifold of an internal combustion engine includes the steps of (1) forming a main part from a plastic material by injection molding, (2) forming a runner insert for each engine cylinder from a plastic material by injection molding, and (3) individually attaching each runner insert to the main part to ensure the distance between two adjacent runner inserts is within a predetermined limit.

An air intake, especially for internal combustion engines with a V-shaped cylinder arrangement, which is composed of two units (). From the two units () extend the intake ducts (), each associated with one cylinder bank () of the internal combustion engine. By dividing the air intake device into two units (), the unit () can be mounted first on the internal combustion engine, a free space () for the mounting tool being necessary. Then the unit () is placed and bolted on, the air intake ducts () being able to run through the free space () in the hatched area (), since the unit () is already installed. The advantage of this air intake tube configuration is a substantially greater geometric freedom of design.

A mounting arrangement for an intake manifold and a method of making same. The mounting arrangement includes an adapter plate attached to a cylinder head of an engine. The adapter plate has at least one aperture having a smooth inner surface. The intake manifold includes at least one inlet pipe and is mounted to the adapter plate by arranging the at least one inlet pipe in the at least one aperture of the adapter plate. A securing mechanism is arranged between the at least one inlet pipe and the smooth inner surface of the at least one aperture. The mounting arrangement of the present invention substantially isolates the intake manifold from vibrations caused by the operation of the engine, which in the past have been transmitted to the intake manifold by way of mounting flanges.

A combined air intake manifold and fuel delivery rail for an internal combustion engine which decreases manufacturing and assembly costs, as well as the weight of the engine. An air channel formed in a hollow portion of the manifold registers with air intake ports in the engine head which lead to the individual cylinders of the engine. An elongated recess in the underside of a mounting flange forms a fuel supply channel which communicates with fuel inlet openings in the engine head leading to fuel injectors for the engine cylinders. Seals may be provided between the manifold and the engine head to seal the air channel and the fuel supply channel.
