Methods and systems are provided for removing condensate form a charge air cooler coupled to an engine intake system. In one example, a method may include flowing heated air from a fuel vapor canister of an evaporative emissions control (EVAP) system through the charge air cooler to vaporize condensate in the CAC. The air is drawn in from atmosphere by operating an electric booster in a reverse direction and the air is heated at the canister by operating a canister heater.

A gas-liquid separator includes a cylindrical inlet pipe and a fluid inflow pipe. The inlet pipe includes a fluid inlet which is formed in a fluid entering side and radially opens. An axis line of the inlet pipe horizontally extends. The fluid inflow pipe includes at an end a connection opening connected to the fluid inlet. An axis line of the fluid inflow pipe horizontally extends. The fluid inflow pipe introduces the gas-liquid two-phase fluid through the fluid inlet from a side of the inlet pipe. In a connecting portion, a position of an axis line extending through a center of a connection opening in communication with the fluid inlet is vertically offset with respect to a position of the axis line of the inlet pipe.

An internal combustion engine having an intake manifold, a compressor in fluid communication with the intake manifold, a charge air cooler in fluid communication with and between the compressor and the intake manifold, a throttle controlling fluid communication between the air charge cooler and the intake manifold, and a condensate collection reservoir that collects condensate from the air charge cooler and is in fluid communication with a suction port of a Venturi device in a bypass loop around the throttle. A motive inlet of the Venturi device is in fluid communication upstream of the throttle and a discharge outlet is in fluid communication downstream of the throttle, and under operating conditions that provide an adequate pressure drop across the Venturi device, the suction port draws condensate from the condensate collection reservoir and introduces the condensate into the intake manifold as a mist.

A gas dehumidification device having two heat exchangers, each including a first and second fluid line. Each second fluid line at least partially surrounds the respective first fluid line. Each heat exchanger thermally couples a fluid in the respective heat exchanger second fluid line with a first coolant on an outside surface of the respective heat exchanger second fluid line. The gas dehumidification device further comprises a two-position valve. In a first position, a fluid comprising a higher temperature than the first and/or second coolant is conducted into the first heat exchanger first fluid line and in the second position, the fluid is conducted into the second heat exchanger first fluid line. A controller is configured to place the valve selectively into the first or second position.

A charge air cooler (CAC) condensation dispersion system including a compressor for generating a hot compressed air flow; a CAC having an inlet tank for receiving the hot compressed air flow and an outlet tank for discharging a cooled compressed air flow; a condensate pickup tube having an inlet disposed in a lower volume of space within the outlet tank and an opposite outlet; and a condensate conveyance tube having a first end connected to the outlet of the pickup tube and an opposite second in in fluid connection with the inlet of the compressor. A solenoid actuated control valve is disposed in-line with the condensate conveyance tube. A controller configured to send a signal to the solenoid valve to selectively cycle the control valve between an open state and a closed state. An in-line orifice plate is disposed adjacent the second end of the condensate conveyance tube.

An intercooler assembly includes: a cooler body having a heat exchanger; an upper tank formed at an intake air inlet connected to the heat exchanger and coupled to an upper portion of the cooler body; a lower tank coupled to the lower portion of the cooler body to form an intake air discharge part connected to the heat exchanger; a bypass unit connected to the intake discharge part separately from the intake inlet; and a valve unit connected to the intake air inlet and the bypass unit and selectively introducing intake air supplied through a turbocharger into the intake air inlet and the bypass unit.

An intercooler drain system which drains condensate from an intercooler includes an upper header, a lower header, and a plurality of tubes connecting the upper header and the lower header, the intercooler drain system including: a drain passage allowing the condensate collected in the lower header of the intercooler to be drained; and a valve opening and closing the drain passage. The valve has a specific gravity less than a specific gravity of the condensate, and when the condensate is collected above a predetermined level in the lower header, the valve rises due to buoyancy to open the drain passage.

A method and system for condensing water for injection into an internal combustion engine to increase the engine's fuel economy and performance while reducing emissions. A volume of ambient air is drawn through an intake valve into a sealable chamber. The intake valve is closed and the ambient air compressed within the sealed sealable chamber and thereafter vented through an exit valve to be contained in a cooling section. The cooling section comprises a port and a cooling device. The cooling device, which in one embodiment comprises a refrigeration unit, cools the ambient air contained within the cooling channel to condense water vapor present in the ambient air into liquid water. The liquid water is drained from the cooling channel through the port and collected in a reservoir. Liquid water from the reservoir is then injected into at least one combustion chamber of the internal combustion engine.

A frame device for a fan module for a main cooler and for a charge air cooler of a motor vehicle, comprising a main frame for the main cooler and a charge air cooler, separate from the latter, for the charge air cooler, wherein a seal is provided between the main frame and the charge air frame. Furthermore, the invention relates to a fan module with such a frame device.
