An engine includes a block defining cylinders, a charge-air cooler, and an intake manifold configured to receive air from the charge-air cooler and convey the air to the cylinders. The intake manifold includes an inlet connected in fluid communication with the charge-air cooler, a plurality of runners each associated with one of the cylinders, and a wedge disposed in an air path between the inlet and the runners with a leading edge of the wedge facing the inlet. The wedge is configured to deflect water, condensed in the charge-air cooler, to distribute the water among the runners.

A monitoring system and method for detecting clogging through fouling of an air filter (3) of an internal combustion engine (5) comprising a differential pressure sensor means (7) for determining a differential pressure between an ambient environment and a position directly downstream of the air inlet filter. The system further comprising at least one exhaust flow sensor means (9) for determining the exhaust flow, and a controller (13) which is communicatively connected to each of the sensor means for processing information therefrom. The controller is arranged for determining a first filter resistance coefficient based on, at least, a measurement of the differential pressure, and the exhaust flow. The system is arranged for, using the controller, to calculate a second filter coefficient based on the historic evolution of the first filter coefficient, the controller further arranged for comparing the second filter coefficient to a boundary value, and generating a clogging alarm signal when the second filter coefficient exceeds said boundary value.

A fluid connector, including a tubular member, a connector body, including an exterior opening groove, and a retainer clip to lock the tubular member to the connector body, an assurance cap including one or more latch fingers engaged with the exterior opening groove, and a tool, including an annular collar mountable over the tubular member, and a plurality of fingers carried on and extending axially from the annular collar, the plurality of fingers operatively arranged to engage the latch fingers when the collar and the plurality of fingers are engaged with the assurance cap to disengage the latch fingers from the exterior opening groove to disconnect the assurance cap from the connector body.

Systems, methods and apparatus are disclosed for providing or maintaining a target surge margin at the compressor during steady state engine operating conditions and to avoid compressor surge during transients by controlling a compressor recirculation valve position to a commanded position. The estimated surge margin can be determined in response to the measured pressure ratio across the compressor, an estimated compressor flow, and a compressor map for the compressor.

An air cleaner has a body, an intake part to take air into the body, an exhaust pipe to exhaust the air from the body, a mounting section to mount an air flow meter to the exhaust pipe, a rib disposed on an inner surface of the body, and a straightening element disposed on an inner surface of the exhaust pipe. The rib extends toward the exhaust pipe and the straightening element extends in a same direction where the rib extends. The straightening element is located closer to the body than the mounting section.

An engine intake structure comprises an intake passage member 18 which defines an intake passage 36 for supplying air to an internal combustion engine 12, and which also defines a resonator chamber 40 in communication with the intake passage 36; and an in-vehicle device 14 located in an engine room 10 of a vehicle and having a preset reference temperature for temperature control, the intake passage member 18 being located above and adjacent to the in-vehicle device 14. The intake passage 36 extends above the in-vehicle device 14 so as to at least partially overlap the resonator chamber 40 as viewed in a vertical direction, thereby forming a two-layer structure, which makes the in-vehicle device 14 less affected by ambient temperature in the upper part of the engine room 10.

Methods and systems are presented for diagnosing a breach of an evaporative emissions system. The methods and systems include repurposing a resonator as a vacuum reservoir to reduce a pressure of an evaporative emissions system so that it may be determined if there is or is not a breach of the evaporative emissions system.

An engine system includes an intake manifold and a charge-air cooler disposed upstream of the intake manifold. The charge-air cooler includes a housing defining an enclosure having a water reservoir, a heat exchanger disposed within the enclosure, and a valve disposed within the enclosure. The valve has a flap that is movable between an open position in which airflow is permitted across the water reservoir and a closed position is which airflow across the water reservoir is inhibited.

An acoustic component is provided with a flow channel for a fluid. The flow channel has an inlet pipe and an outlet pipe. A flow channel section is arranged between the inlet pipe and the outlet pipe, wherein the flow channel section has a silencer volume connected in the flow channel section via openings to the flow channel. A flow deflection device is arranged at least in the flow channel section with the silencer volume, wherein the flow deflection device deflects a flow of the fluid in the flow channel section with the silencer volume away from the openings. The openings in the flow channel section are arranged in a sheltered zone of the flow deflection device.

An internal combustion engine is provided with: two intake pipe portions for guiding intake air to two banks; and a blow-by gas recirculation pathway for leading blow-by gas to the two intake pipe portions from a cylinder head or a crank case that includes the two banks. The blow-by gas recirculation pathway includes a distribution passage which is provided between the two intake pipe portions, and which distributes the blow-by gas and allows the same to flow to the two intake pipe portions.
