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 chamber for absorbing condensate formed in a charge-air-cooler of a turbocharged engine system. The chamber may include desiccant to absorb the moisture. The chamber may also include a valve that is controlled by the vehicle control module to open to allow airflow to pass by the desiccant and absorb the moisture from the desiccant or to place in a closed position to allow the desiccant to absorb the condensate formed in the charge-air-cooler.

The dual pass intercooled supercharger includes a supercharger and intercooler. The system is configured such that air leaving the supercharger traverses the intercooler from one side to an opposing side two or more times.

Methods and systems are provided for cleaning out condensate stored at a charge air cooler. In response to increased condensate accumulation at a charge air cooler, airflow through the engine is increased to purge the condensate while an engine actuator is adjusted to maintain engine torque. Combustion stability issues of engine cylinders are addressed by adjusting fueling of each cylinder individually during condensate ingestion.

Methods and systems are provided for estimating water storage in a charge air cooler (CAC). In one example, engine operation may be adjusted responsive to water storage parameters at the CAC, the water storage parameters based on an output of a first oxygen sensor positioned downstream of the CAC and a second oxygen sensor positioned upstream of the CAC. Further, operation of the first oxygen sensor and the second oxygen sensor may be diagnosed during certain engine operation conditions wherein no condensate is forming in the CAC.

A charge air cooling chamber has a lower wall with an orifice in the lower wall. A condensate pipe is fluidly connected to drain exhaust fume condensate from the orifice into a collection tank. A vent pipe is fluidly connected to vent fumes from an upper opening of the collection tank to an exhaust stack. A loop seal is fluidly connected to drain condensate from a lower opening of the collection tank. Exhaust gas moisture condensate drains from the cooling chamber into the collection tank, via the continuously open orifice. Exhaust gas moisture condensate fumes vent from the collection tank to the exhaust stack.

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.

When a deceleration request is issued while the engine load of an internal combustion engine 10 is in a predetermined high-load region, and the vehicle is decelerated so that the engine load transitions from the high-load region to a low-load region to respond to the deceleration request, control is performed that continues a fuel supply from injectors 36 of a first cylinder #1 and a fourth cylinder #4 and cuts a fuel supply from injectors 36 of a second cylinder #2 and a third cylinder #3. Condensed water generated in an intercooler 24 is caused to flow between two guide devices 22c provided at the bottom of a convergence portion 22a of an intake manifold 22 to thereby flow into intake branch pipes 22b of the second cylinder #2 and third cylinder #3.
