    Abstract: An environmental control system for an aircraft. The environmental control system is powered by engine bleed air. A primary turbocharger is provided that includes a first turbine and a first compressor. The first turbine is powered by the engine bleed air. The first compressor draws ambient air and creates a first compressed air supply without ever exposing the first compressed air supply to the engine bleed air. A secondary turbocharger is provided that has a second compressor and an expansion turbine. The second compressor further compresses the first compressed air supply to create a second compressed air supply. A heat exchanger is provided that cools the second compressed air supply to create a cooled compressed air supply. The cooled compressed air supply powers the expansion turbine. This causes the cooled compressed air supply to losing both heat and pressure to become a conditioned air supply.

    Abstract: A charge air cooler for use with a turbocharged engine system of a motor vehicle includes an outlet tank in fluid communication with a heat exchanger core. A condensation separator comprising an array of baffle plates is disposed adjacent a fluid outlet of the outlet tank. The baffle plates are spaced apart from each other and each of the baffle plates includes an alternating pattern of ridges and grooves formed therein to form a tortuous flow channel between adjacent ones of the baffle plates. The tortuous flow channels cause liquid water originating from the heat exchanger core and flowing through the condensation separator to encounter a surface of the baffle plates before exiting the fluid outlet. The baffle plates may be covered with a surface feature adapted to capture or absorb the liquid water, thereby preventing an undesired quantity of liquid water from entering the engine of the motor vehicle.

  • Patent number: 8984878
    Abstract: An internal combustion engine has a cylinder head having at least one cylinder. A cover is connected to the cylinder head and covers the cylinder and related valve train components. An exhaust gas turbocharger powered by the engine's exhaust system delivers compressed gasses to the intake system. An exhaust gas recirculation system branches off from the exhaust system downstream of the turbocharger and feeds into the intake system upstream of the turbocharger. A coolant-fed charge air cooler is disposed between the cylinder head and the cover, and at a point that is a geodetically highest point in the intake system when the internal combustion engine is in an installed position. This configuration prevents any liquid that has condensed out of the charge air during cooling from collecting in the cooler and/or in the intake system between the cooler and the at least one cylinder.

  • Publication number: 20150040559
    Abstract: An intake-exhaust gas handling system for an internal combustion engine includes an intake system, an exhaust system, an intake cooler, and an exhaust gas recirculation (EGR) system. The intake system provides an intake charge, which can be a mixture of exhaust gas and air, to the internal combustion engine. The exhaust system removes exhaust gas generated by the internal combustion engine after a combustion process. The intake cooler can be disposed at the intake system for cooling the intake charge prior to its discharge into the internal combustion engine. The EGR system routes exhaust gas from the exhaust system to the intake system, where it is mixed with air at a position upstream of the intake cooler.
