  • Patent number: 9371802
    Abstract: In an engine provided with a supercharger and a low pressure loop EGR apparatus, an ECU controls an EGR valve to fully close when a detected operating condition is a predetermined operating condition. An outlet of an EGR passage is located at a higher position than an inlet in a vertical direction to allow condensed water to flow downward from downstream to upstream of the EGR valve and flow downward through the EGR passage to an exhaust passage. When the EGR valve has to be controlled to fully close, the ECU forcibly opens the EGR valve when a predetermined discharge condition is established to discharge the condensed water from a downstream side of the EGR valve.

  • Patent number: 9341103
    Abstract: The present invention refers to a device (1) for water circulation in a cooling circuit of an internal combustion engine (3). The device comprises a pump and a suction chamber (8) which develop in a circular way around the axis of the pump impeller. The device comprises also a water manifold (50) that can be connected to the outlet of a radiator (40) of said cooling circuit. The device comprises a first duct (5) connected to the manifold and a first opening (5?) which defines an axial inlet for said first flow in said chamber (8). The device comprises also a second duct (6) connected to the manifold (50) and to the suction chamber (8?) by means of a second opening (6?). The latter defines a tangential intake for water, so that it is subject to a rotation around the axis of the impeller. The device further comprises flow rate partition means (9) suitable to vary the flow rate of the water circulating in both ducts (5,6) as a function of the operating conditions of said engine.

  • Patent number: 9341127
    Abstract: Methods and systems are provided for adjusting a LP-EGR valve and an LP intake throttle to provide a desired LP-EGR flow rate while maintaining a minimum differential pressure. In one example, a method for a turbocharged engine method comprises: responsive to a differential between intake and exhaust pressure below a threshold, adjusting a LP-EGR valve while adjusting a LP intake throttle to regulate a LP-EGR flow rate and the differential to respective setpoints; and responsive to the differential above the threshold, saturating the LP-EGR valve to minimize the differential while actuating the throttle to regulate the flow rate to its setpoint. In this way, control of the LP-EGR system may be more robust to disturbances at very low differential pressures, require less actuator movement, and increase fuel economy.

  • Patent number: 9267738
    Abstract: An air conditioning system for a vehicle includes a heat exchanger, a case clamping an outer peripheral part of the heat exchanger in its thickness direction, and an elastic body disposed at the outer peripheral part of the heat exchanger between the case and the heat exchange. The opposite side of the exchanger is held directly by the case. The elastic body is compressively deformed between the case and the heat exchanger to clamp the heat exchanger. A region of the outer peripheral part of the exchanger includes a planar portion at least on one side of the exchanger. The case includes an air stop rib at a position of the case opposed to the planar portion in the thickness direction of the exchanger. The air stop rib is located adjacent to the planar portion to limit an air leak.

  • Patent number: 9261056
    Abstract: An intake enhancement system is arranged for incorporating with a vehicle which includes a combustion engine and a heat exchanger for generating a cooling effect. The intake enhancement system includes an intake cooling unit for delivering a combustion element to the combustion engine, wherein the intake cooling unit is thermally conducted with the heat exchanger for heat-exchanging the combustion element with heat exchanging agent of the heat exchanger so as to substantially cool down the combustion element along the intake cooling unit before the combustion element delivers to the combustion engine.

  • Patent number: 9249998
    Abstract: An air-cycle air conditioning system and method, using an automotive turbocharger as the core of the system, was designed and tested. Effects on engine performance were minimized while maximizing the possible cooling possible and also minimizing weight and space requirements. An unmodified automotive turbocharger was tested initially as a baseline in a Reversed-Brayton Cycle air cooling system. A second air-cycle machine, assembled from commercial turbocharger components chosen individually to optimize their performance for cooling purposes, was tested to improve the overall cycle efficiency. An optimized air-cycle air conditioning system was tested on an internal combustion engine to simulate more realistic operating conditions and performance.

  • Patent number: 9217362
    Abstract: A method is disclosed for controlling a two-stage turbocharger system having low-pressure and high-pressure turbochargers in line, sequentially, with an engine. The turbochargers include a low-pressure (LP) turbine and an LP compressor, and a high-pressure (HP) turbine and an HP compressor. The LP compressor feeds the HP compressor, which feeds the engine intake. The engine exhaust feeds the HP turbine, which feeds the LP turbine. The method determines a total boost pressure, which provides combustion reactant for the engine. The method calculates an LP compressor power from the determined total boost pressure, and an LP turbine flow from the LP compressor power. The low-pressure turbocharger operates at the calculated LP turbine flow. The method calculates an HP compressor power from the determined total boost pressure, and an HP turbine flow from the HP compressor power. The high-pressure turbocharger operates at the calculated HP turbine flow.
