An intake system for a vehicle may include an intake manifold having an internal space divided into a first chamber and a second chamber by a partition wall, in which intake air flows into the first chamber through a charging path and is then discharged to a portion of an intake port connected to the intake manifold; and intake air flows into the second chamber through a bypass path bypassing charger and is then discharged to another portion of the intake port.

An agricultural harvester includes an IC engine, a grain tank, and a fluid cooling system for at least one component onboard the agricultural harvester. The fluid cooling system has a cooling package positioned between the IC engine and the grain tank. The cooling package includes a housing, and a plurality of cooling units arranged in a side-to-side manner within the housing, transverse to a fore-aft direction of the harvester.

A cooling arrangement for cooling charge air of a supercharged internal combustion engine. In a charge-air line that leads to the internal combustion engine, there are provided a compressor arrangement, which has at least one compressor stage, and an expansion arrangement, which has at least one expansion stage for lowering the pressure level and thus for cooling the charge air. A cooling device is provided between the compressor arrangement and the expansion arrangement. The at least one compressor stage and the at least one expansion stage are connected in series and are respectively connected in terms of drive to an electric motor. The compressor arrangement has at least two compressor stages connected in parallel.

According to the present invention, a rotary blower or supercharger includes a recirculation loop for readmitting pressurized outlet gas back into the rotor chambers, and cooling means for cooling the pressurized outlet gas before it is readmitted into the rotor chambers, thereby providing a supercharger having a lower operating temperature and a higher operating pressure capability. In the preferred embodiment of the present invention, a supercharger includes a housing assembly defining first and second transversely overlapping cylindrical chambers. The housing defines an inlet port for the inflow of an inlet gas, and an outlet port for the outflow of the outlet gas. The supercharger further has first and second meshed, lobed rotors respectively disposed in the chambers for counter rotation about axes substantially coincident with the chamber axes. According to the present invention, the housing further includes a recirculation port and a recirculation flow path for recirculation of a portion of outlet gas flowing out of the outlet port back into cylindrical chamber. The recirculation flow path further including cooling means for cooling of at least a portion of the outlet gas, thereby providing a cooler operating supercharger.

An intake air cooling device includes an intake manifold communicating with intake ports, and an intercooler disposed laterally of a cylinder head for cooling intake air. The intake manifold includes a manifold body fastened to the cylinder head, and a cooler forming portion communicating with the upstream end of the manifold body and constituting the lower end of the intercooler. Assuming that the cooler forming portion is a second cooler forming portion, the intercooler includes a first cooler forming portion mounted on the upper portion of the second cooler forming portion. The intercooler is constituted by the first and second cooler forming portions. The manifold body includes a plurality of fixing portions fastened to the surface of the cylinder head. The fixing portions are located on the outside of the second cooler forming portion in a side view along a direction orthogonal to the cylinder array direction.

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.

An engine having an integrated heat exchanger includes a cylinder head defining combustion chambers; an intercooler embedded at an intake side in the cylinder head and cooling intake gas by using a coolant; an EGR cooler embedded in the cylinder head and cooling exhaust gas, which is discharged from an exhaust side of the combustion chambers and recirculates to the intake side of the combustion chambers through an EGR passageway formed in the cylinder head; and an EGR distribution tube formed at an upper side in the cylinder head, supplied with the exhaust gas passing through the EGR cooler, and having distribution holes through which the exhaust gas is distributed into intake ports connected with the combustion chambers.
