A motor vehicle has a supercharged internal combustion engine arranged at the rear and can be fed cooled combustion air via a charge air cooler (7). The charge air cooler (7) is positioned above the internal combustion engine below a covering hood (4) for the internal combustion engine. The charge air (B.sub.EIN) is fed via at least one charge air inlet opening in a charge air inlet shaft (8) that adjoins the covering hood (4) and is discharged via at least one charge air outlet shaft (B.sub.AUS) that is connected to outlet openings (13, 14) in the region of a license plate recess (9) of the motor vehicle.

A charge air cooler shroud mounting system is provided. The charge air cooler shroud has a body having a four point attachment system including a mounting aperture, a first lug, a second lug and a third lug. The mounting aperture provides a fixed point of attachment while the lugs provide a plurality of floating points of attachment.

Methods and systems are provided for controlling a condensate level in a charge air cooler. In one example, a method may include adjusting an air flow to a membrane in response to a condensate level in the charge air cooler.

A cooling system is provided for an engine. The cooling system may have an air cooler configured to cool intake air being supplied to the engine. The cooling system may also have a sensor configured to generate a temperature signal indicative of a temperature of the intake air and a fan in proximity to the air cooler. The cooling system may further have a controller in communication with the sensor and the fan. The controller may be configured to cause the fan to operate at a speed that is a function of the temperature signal when the temperature of the intake air is above a threshold temperature. The controller may further be configured to selectively cause the fan to pulse when the temperature of the intake air drops below the threshold temperature.

A two-piece nested air intake scoop for an engine cowl and methods of assembly and manufacture. The nested air intake scoop includes an air intake scoop lower duct and an air intake scoop upper duct coupled to the air intake scoop lower duct. The air intake scoop upper duct is reversibly nested within the air intake scoop lower duct. Reversibly nested includes at least two surfaces of the air intake scoop upper duct airtight mechanically connected to at least two surfaces of the air intake scoop lower duct.

A method of operating a forced induction gaseous-fueled engine includes mixing gaseous-fuel and engine intake air to form a mixture at a fuel mixer. The method includes delivering the mixture to an intake manifold by at least partially bypassing a charge air cooler.

Methods and systems are provided for adjusting engine operating parameters to regulate condensate formation in a charge air cooler. Based on conditions conducive to condensate formation, one or more of throttle valve position, active grille shutter opening and compressor speed may be regulated in order to decrease dew point temperature and condensation at the charge air cooler.

An engine system includes a charge air cooler assembly that is configured to direct air to different parts of the engine system and to reduce overall void volume within the air intake system. The charge air cooler assembly includes a first stage air-to-air cooler arranged to direct a first charge air along a first direction from an inlet to an outlet of the first stage air-to-air cooler. The charge air cooler assembly also includes a second stage air-to-air cooler arranged to direct a second charge air along a second direction from an inlet to an outlet of the second stage air-to-air cooler that is different from the first direction. In some embodiments, the first stage air-to-air cooler and the second stage air-to-air cooler are each disposed in a parallel flow arrangement relative to an air driver of the engine system.

A bidirectional active ventilation (BDAV) unit includes a housing that is mountable within a cover of an engine compartment of a vehicle, and a retractable intake scoop attached to the housing. The retractable intake scoop is movable between a first position that permits airflow into the engine compartment and a second position that permits airflow out of the engine compartment.
