An air intake system for directing intake air to an internal combustion engine of a machine is disclosed. The air intake system may comprise an air compressor configured to increase a pressure of the intake air, and a membrane unit downstream of the air compressor and having a membrane with selectivity for siloxanes. The membrane may have a first side and a second side, and the first side may be exposed to a higher pressure than the second side when the air compressor is operating. The membrane may be configured to separate the intake air into a permeate that traverses the membrane from the first side to the second side, and a retenate that remains on the first side. The permeate may have a higher siloxane content than the retenate. The retenate may be directed to the internal combustion engine for combustion.

A heat exchanger, especially a charge-air cooler or exhaust-gas cooler, with a tube-to-tubesheet sub-assembly, in which tubes are inserted in a sealed manner by their ends into openings of two oppositely-disposed tubesheets, wherein at least one region of a housing is arranged between the two tubesheets and encompasses and outwardly seals the tubes of the sub-assembly, wherein the two tubesheets have two sides extending parallel to each other and adjoining an end region of the tubes in each case, and on which is arranged in each case a housing section which is connected to the housing, wherein on at least one of the tubesheets a seal is arranged with sealing effect between the housing and this tubesheet and/or between this tubesheet and the housing section which is arranged on this tubesheet.

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 charge air cooler for an internal combustion engine may include a heat exchanger having a plurality of fluid paths through which charge air to be cooled is flowable. The charge air cooler may also include a collector attached to the heat exchanger and communicating with the fluid paths. A lower region of the collector may be configured as a condensate receiving zone for receiving condensed charge air. At least one pipe body may be arranged in the collector and may delimit a fluid channel through which condensed and non-condensed charge air may be flowable. An opening may be formed in the at least one pipe body and may fluidically connect the fluid channel to the condensate receiving zone.

A thermal management system and method for a vehicle includes a cooling system having a variable cooling capacity and which is connectable to a heat-producing system of the vehicle. A control system is configured to increase the cooling capacity of the cooling system to a first predetermined level in response to the at least one input indicating an increase in the future heat load of the heat-producing system when a temperature of the cooling system is at least a predetermined temperature and the cooling system is operating below the first predetermined level. The control system is also configured to inhibit increasing the cooling capacity of the cooling system to the first predetermined level in response to the at least one input indicating an increase in the future heat load of the heat-producing system when the temperature of the cooling system is less than the predetermined temperature.

An electrically assisted exhaust gas turbocharger has a fresh air-conducting section, an exhaust gas-conducting section and a bearing section. A rotating assembly includes a shaft and a compressor wheel connected to the shaft. A turbine wheel is connected to the shaft for conjoint rotation. The compressor wheel is rotatably accommodated in the fresh air-conducting section and the turbine wheel is rotatably accommodated in the exhaust gas-conducting section. The shaft is rotatably mounted in the bearing section and has an electric motor with a rotor and a stator. The rotor is arranged in operative connection with the shaft. A coolant channel in the electrically assisted exhaust gas turbocharger is designed for coolant to flow therethrough. The coolant is compressed air downstream of the compressor wheel and can be fed to the compressor wheel downstream and/or upstream thereof. A sealing element is formed between the electric motor and the fresh air-conducting section.

An off-road vehicle includes a vehicle body frame, a cabin, an engine room, an internal combustion engine, and an engine room cover. The engine room is provided behind the cabin. The engine is provided in the engine room and supported by the frame. The intercooler includes an intercooler core and is provided along an intake conduit extending toward the engine and provided above the engine. The engine room cover includes an upper surface exposed to outside the vehicle, is provided above the engine, and defines an upper boundary of the engine room. The engine room cover is provided above the intercooler and includes a window opening through which the intercooler core is exposed to outside the vehicle. The window opening includes a circumferential edge portion that faces an upper surface of the intercooler from above. The window opening is provided along an outer circumferential edge of the intercooler core.

A charge air cooler for an internal combustion engine, includes a charge air inlet and a charge air outlet which are fluidly connected with each other via multiple charge air channels which are arranged parallel to each other and arranged parallel to each other and subjectable to a coolant flow; and at least one flow guide element arranged upstream of the charge air channels, wherein the flow guide element at least in one operating state of the internal combustion engine deflects charge air entering through the charge air inlet the direction of a condensate accumulation volume of the charge air cooler.

A charge air cooler (CAC) device includes a body including an inlet end, an outlet end, and a plurality of passages extending between the inlet end and the outlet end. At least one of the plurality of passages is covered by an inlet blocking member at the inlet end.

A charge air cooler shroud is provided. That charge air cooler shroud includes a main body having an access opening and a removable access panel carried on the main body and covering the access opening. A method is also disclosed for mounting a cooling module to a frame of a motor vehicle.
