Methods and systems are provided for regulating airflow through a charge air cooler integrated in an intake assembly. In one example, an engine intake assembly comprises a plenum having an integrated charge air cooler (CAC), a first header seal positioned around a circumference of a first CAC header, and a first rotatably movable seal positioned in a bypass passage of the plenum. The first movable seal interfaces via sliding contact with the first header seal and adjusting a position of the first movable seal may vary the amount of airflow through the bypass passage.

An apparatus and method for a heat shield with an integrated air filter assembly is disclosed. Wherein the air filter assembly comprising a filter material circumferentially extending such that the filter material surrounds at least a portion of an interior cavity of the air filter, a distal end cap affixed to a distal end of the filter material, and a wire support extending along at least a portion of an exterior surface of the filter material; and wherein the heat shield is configured to direct cooler air into an air intake conduit extending from an intake portion of an automobile engine for combustion.

Systems are disclosed for power systems and enclosures having an improved compressor drive. In examples, a power system includes a generator to be driven by an engine. The generator is coupled to the engine on a first side of the generator and has a clutch extending from a second side of the generator opposite the engine. The clutch is coupled to the engine. A compressor is positioned at the second side of the generator opposite from the engine. The compressor comprising a shaft extending toward the generator and configured to be driven by the clutch.

An engine cover covers an engine; and an intake pipe through which the air is introduced into the engine. An intake silencer is provided adjacent to the intake pipe and suppresses air pressure fluctuations of air in the intake pipe to reduce intake sound. A portion of the intake silencer is covered with the engine cover, and a remaining portion is exposed with respect to the engine cover. An advantage is that secondary noise generated by the intake silencer and a temperature increase of air suctioned into the engine are simultaneously suppressed.

Disclosed is a transport refrigeration unit (TRU) having: an engine configured to power a refrigeration system of the TRU, the engine including an air intake, the engine within an engine compartment of the TRU; an air management valve (AMV) fluidly coupled to the air intake; a first duct fluidly coupled to the AMV and including a first inlet within the engine compartment; and a second duct fluidly coupled to the AMV and including a second inlet that is exterior to the engine compartment and is configured to receive atmospheric air; wherein: the AMV is configured to modulate air into the engine from the first duct and the second duct, when a temperature of air within the AMV is above the first threshold and the temperature of air within the second duct is below the first threshold, to lower the temperature of air entering the engine to below the first threshold.

Methods and systems are provided for a hydrocarbon (HC) trap system in an engine air induction system. In one example, a system may include a pillow-case type HC trap housed in a rectangular opening formed in a wall of an air conduit at the outlet of an air cleaner box. A frame may be integrally formed around the opening to support the HC trap protruding outward from the wall.

In an engine compartment, a separation wall is provided between an intake pipe, which runs around to a rear side of the engine from a lateral side of the engine, and the engine. On an outer side of this separation wall, a travel wind guide having a vertical wall portion that opposes the separation wall with the intake pipe being therebetween is provided. The travel wind guide guides vehicle travel wind that is introduced into the engine compartment in a manner to cause the vehicle travel wind to flow along the intake pipe on the outer side of the separation wall.

This air distributor (1) comprises two half-shells (2) made of plastic material and a stack of plates (4) made of plastic material, the two half-shells (2) defining a volume inside of which the stack of plates (4) is positioned, the stack of plates (4) comprising two end plates (40) and the stack of plates (4) defining between its adjacent plates (4) a set of intermediate spaces (10) suitable for a fluid circulation. The plates (4) of the stack of plates (4) are attached to one another, each end plate (40) is attached to one of the two half-shells (2), and the two half-shells (2) are attached to one another.

An air intake apparatus for an internal combustion engine includes an outer port member facing an inner surface of a suction port, an inner port member arranged inside the outer port member, and a heater arranged inside the inner port member. The inner port member is stacked on an outside of the heater in a direction orthogonal to an intake flow direction of the suction port, and is configured to insulate heat from the heater.

An air fin for a heat exchanger has air channels defined by corrugations, the corrugations having generally planar flanks joined by alternating crests and troughs. Perforations extend through portions of at least some of the flanks and are aligned within two spaced apart planes. A rectangular aperture extends through at least two consecutive ones of the corrugations, and is bounded by the two planes. A method of making the air fin includes forming perforations into a continuous strip of metal sheet at regular intervals, corrugating the strip to form crests and troughs between the perforations, and punching out a portion of the strip at regular intervals. The punching out includes shearing webs between the perforations, and results in the formation of the rectangular aperture.
